University Hospital Coventry
University Hospital Coventry is a large National Health Service hospital situated in the Walsgrave on Sowe area of Coventry, West Midlands, England, 4 miles from the city centre. It is part of Warwickshire NHS Trust, it has a large, progressive accident & emergency department providing a trauma service to Coventry and Warwickshire, is one of the largest of its kind outside London. The original hospital on the site, known as the Walsgave Hospital, opened in stages: the maternity unit opened in 1966, the general unit opened in 1969 and the psychiatric unit opened in 1973, it was demolished in spring 2007. A new hospital was procured under a Private Finance Initiative contract to replace the Walsgrave Hospital and the Coventry & Warwickshire Hospital in 2002; the hospital was built by Skanska at a cost of £ 440 million. Construction started in July 2002 and the hospital opened on 10 July 2006. Skanska subsequently sold its stake to Innisfree for £66 million; the hospital is equipped with 27 operating theatres.
On 26 March 2012, the hospital was designated as one of four trauma units in the West Midlands Region. In 2012, the planning committee approved an application to build a new car park at the hospital, to help improve ongoing congestion and traffic issues; the trust was one of 26 responsible for half of the national growth in patients waiting more than four hours in accident and emergency over the 2014/5 winter. It was named by the Health Service Journal as one of the top hundred NHS trusts to work for in 2015. At that time it had 6198 full-time equivalent staff and a sickness absence rate of 3.99%. 70 % of staff recommend it as a place for 64 % recommended it as a place to work. The hospital plays host to Coventry Hospital Radio, a free station provided through the Hospedia bedside units and now online via their website; the station started broadcasting in 1972. Coventry Hospital Radio did provide commentary on every match until the move to the Ricoh Arena in 2005. Since 2016 the Saturday afternoon sports show has provided the latest football scores and rugby scores plus other sporting action.
The station is managed by an elected committee. The station is situated on the 5th floor and is available to all wards and online via the web providing music and chat 24 hours a day, 7 days a week; this year, Coventry Hospital Radio was shortlisted for three National HBA Radio Awards. Radio presenter, Dan Sambell, won a Gold award for "Best Male Presenter" and husband and wife team Colin and Annette Gutteridge were awarded Bronze for Programme With Multiple Presenters; the Meriden Hospital is a private hospital run by BMI Healthcare. It is situated within opposite to the NHS hospital. List of hospitals in England List of NHS trusts Warwick Hospital University of Warwick University Hospital Coventry Coventry Hospital Radio
International Civil Aviation Organization
The International Civil Aviation Organization is a specialized agency of the United Nations. It codifies the principles and techniques of international air navigation and fosters the planning and development of international air transport to ensure safe and orderly growth, its headquarters is located in the Quartier International of Montreal, Canada. The ICAO Council adopts standards and recommended practices concerning air navigation, its infrastructure, flight inspection, prevention of unlawful interference, facilitation of border-crossing procedures for international civil aviation. ICAO defines the protocols for air accident investigation followed by transport safety authorities in countries signatory to the Chicago Convention on International Civil Aviation; the Air Navigation Commission is the technical body within ICAO. The Commission is composed of 19 Commissioners, nominated by the ICAO's contracting states, appointed by the ICAO Council. Commissioners serve as independent experts, who although nominated by their states, do not serve as state or political representatives.
The development of international Standards And Recommended Practices is done under the direction of the ANC through the formal process of ICAO Panels. Once approved by the Commission, standards are sent to the Council, the political body of ICAO, for consultation and coordination with the Member States before final adoption. ICAO is distinct from other international air transport organizations, like the International Air Transport Association, a trade association representing airlines; the forerunner to ICAO was the International Commission for Air Navigation. It held its first convention in 1903 in Berlin, but no agreements were reached among the eight countries that attended. At the second convention in 1906 held in Berlin, 27 countries attended; the third convention, held in London in 1912 allocated the first radio callsigns for use by aircraft. ICAN continued to operate until 1945. Fifty-two countries signed the Chicago Convention on International Civil Aviation known as the Chicago Convention, in Chicago, Illinois, on 7 December 1944.
Under its terms, a Provisional International Civil Aviation Organization was to be established, to be replaced in turn by a permanent organization when 26 countries ratified the convention. Accordingly, PICAO began operating on 6 June 1945, replacing ICAN; the 26th country ratified the Convention on 5 March 1947 and PICAO was disestablished on 4 April 1947 and replaced by ICAO, which began operations the same day. In October 1947, ICAO became an agency of the United Nations linked to the United Nations Economic and Social Council. In April 2013 Qatar offered to serve as the new permanent seat of the Organization. Qatar promised to construct a massive new headquarters for ICAO and cover all moving expenses, stating that Montreal "was too far from Europe and Asia", "had cold winters," was hard to attend due to the refusal of the Canadian government to provide visas in a timely manner, that the taxes imposed on ICAO by Canada were too high. According to The Globe and Mail, Qatar's move was at least motivated by the pro-Israel foreign policy of Canadian Prime Minister Stephen Harper.
One month Qatar withdrew its bid after a separate proposal to the ICAO's governing council to move the ICAO triennial conference to Doha was defeated by a vote of 22–14. The 9th edition of the Convention on International Civil Aviation includes modifications from 1948 up to year 2006. ICAO refers to its current edition of the Convention as the Statute, designates it as ICAO Document 7300/9; the Convention has 19 Annexes that are listed by title in the article Convention on International Civil Aviation. As of January 2019, there are 192 ICAO members, consisting of 191 of the 193 UN members, plus the Cook Islands. Liechtenstein has delegated Switzerland to enter into the treaty on its behalf and the treaty applies in the territory of Liechtenstein; the Republic of China was a founding member of ICAO but was replaced by People's Republic of China as the legal representative of China in 1971 and as such, did not take part in the organization. In 2013, the Republic of China was for the first time invited to attend 38th session of ICAO Assembly as a guest under the name of Chinese Taipei.
The Council of ICAO is elected by the Assembly every 3 years and consists of 36 members elected in 3 groups. The present Council was elected on 4 October 2016 at the 39th Assembly of ICAO at Montreal; the structure of the present Council is as follows: ICAO standardizes certain functions for use in the airline industry, such as the Aeronautical Message Handling System. This makes it a standards organization; each country should have an accessible Aeronautical Information Publication, based on standards defined by ICAO, containing information essential to air navigation. Countries are required to update their AIP manuals every 28 days and so provide definitive regulations and information for each country about airspace and airports. ICAO's standards dictate that temporary hazards to aircraft are published using NOTAMs. ICAO defines an International Standard Atmosphere, a model of the standard variation of pressure, temperature and viscosity with altitude in the Earth's atmosphere; this is useful in designing aircraft.
USS San Antonio
USS San Antonio, the lead ship of her class of amphibious transport dock or landing platform dock, is the first ship of the United States Navy to be named for the city of San Antonio, Texas. San Antonio is the first U. S. Navy vessel to incorporate new crew comfort features, including bunks with increased headroom, in-rack fans, pull-out laptop computer shelves, she is the largest U. S. Navy vessel to incorporate stealth features, with close attention paid to exterior shaping. Major antennas are mounted on platforms inside two Advanced Enclosed Mast/Sensor systems rather than on traditional mast yardarms which are exposed to the environment. Deck edges are bounded by shaped bulwarks rather than lifeline stanchions; these bulwarks are double as storage lockers, eliminating locker clutter on decks. Exterior equipment is recessed or flush-mounted where possible, giving the ship a clean exterior appearance. Any equipment that cannot be flush-mounted incorporate shaping features of their own; the boat-handling crane at the center of the ship folds into a clean shape when not in use.
The anchor and anchor pocket are shaped to minimize radar backscatter. On 17 December 1996, the U. S. Navy awarded a contract to an industrial alliance led by Northrop Grumman Ship Systems, with General Dynamics Bath Iron Works, Raytheon Electronic Systems and Intergraph Corporation, to design and construct the first of an anticipated 12 ships under the Navy's LPD-17 program; the keel was laid down on 9 December 2000. The ship was launched on 12 July 2003 and christened on 19 July by Senator Kay Bailey Hutchison of Texas, she was scheduled to be commissioned 17 July 2002, but was delayed by problems at the Avondale shipyard, which resulted in her being towed from New Orleans to the Northrop Grumman shipyard at Pascagoula, Mississippi, in December 2004 for completion. The Navy took delivery three days before Hurricane Katrina hit in August 2005. Work was delayed further when the ship became a base for regional relief efforts, including accommodations for some shipyard workers, the National Guard, Navy diving and salvage personnel and government officials.
The ship's final cost was $840 million over budget. The ship arrived at her homeport of Norfolk, Virginia on 18 December 2005, she was commissioned 14 January 2006, at NS Ingleside, Texas. Guest speakers included former U. S. President George H. W. Bush. Senator Hutchison, the ship's sponsor, gave the crew the customary first command, "Man our ship, bring her to life!" In 2009, San Antonio served as a flagship for Combined Task Force 151, the multi-national anti-piracy naval force off Somalia. During the ship's time off Africa, the crew boarded 20 foreign vessels; the crew discovered hidden explosives on one of the vessels. The ship returned to Norfolk on 27 March 2009. In August 2013, the Navy confirmed, they stressed it was a long-planned action and not related to the arrival of destroyers, stationed there due to the conflict in Syria. Officials thought it prudent to keep the ship near the destroyers, given the situation. In October 2013, Al Qaeda operative Abu Anas al-Libi was seized in Libya and transferred to San Antonio to await transport to the United States for a trial and questioning.
On 12 October 2016, San Antonio and destroyer Mason were transiting through the southern end of the Red Sea when missiles were fired at them from Houthi-controlled territory in Yemen. Neither ship was harmed. In response to the attack on Mason and San Antonio, the destroyer Nitze launched five cruise missiles against three radar sites in Yemen that U. S. officials believe targeted the U. S. ships. On 21 October 2016, San Antonio deployed to the Mediterranean Sea as part of Operation Odyssey Lightning to replace amphibious assault ship Wasp, carrying out operations against ISIS. San Antonio carried UH-1 Y Hueys and AH-1 W Cobras from the 22nd MEU's Aviation Combat Unit, VMM-264. Nearly three years after commissioning, problems persisted with this first-in-class vessel. On 27 January 2006, a contract worth over $6 million was awarded to Northrop Grumman, for the Post-Shakedown Availability of San Antonio. Work was expected to be completed by April 2007. On 22 June 2007, Secretary of the Navy Donald C.
Winter sent a letter to Northrop Grumman outlining problems with the ship, from leaks to steerage issues, stating, "Twenty-three months after commissioning of LPD-17, the Navy still does not have a mission-capable ship."In November 2008, two months into her maiden deployment, San Antonio had been forced to undergo an unplanned maintenance stop in Bahrain due to leaks in its lube oil piping system. During a February 2009 transit of the Suez Canal, with both shafts at full power, one shaft went into reverse, sending the vessel careening out of control and narrowly missing other ships and running aground. During an anti-piracy mission in February 2009, one of the ship's crew, Petty Officer 1st Class Theophilus K. Ansong, 34, of Bristol, was killed in a small boat accident in the Gulf of Aden; the ship's captain, Commander Eric C. Cash, was reprimanded over the incident at an admiral's mast by Admiral J. C. Harvey Jr. the commander of Fleet Forces Command. Another officer, Lieutenant Commander Sean Kearns, the ship's executive officer refused a mast over the same incident and was court-martialed in October and November 2010.
During the trial, his defense team presented evidence of the ship's numerous deficiencies and lack of written procedures as contributing to the accident. Kearns was acquitted of the charges on 5 November 2010. Kearns stated that the ship's officers had been pressured by the Navy to declare the ship ready
Leeds General Infirmary
Leeds General Infirmary known as the LGI, is a large teaching hospital based in the centre of Leeds, West Yorkshire, is part of the Leeds Teaching Hospitals NHS Trust. Its previous name The General Infirmary at Leeds is still sometimes used, it is the second largest hospital in Leeds after St James's University Hospital. The first hospital known as Leeds Infirmary was opened in 1771 on what is now the site of the former Yorkshire Bank in Infirmary Street off City Square, Leeds. Notably, the founding five physicians at the infirmary were all graduates of the University of Edinburgh Medical School. Construction of the current hospital on its new site in Great George Street started in 1863 to the designs of Sir George Gilbert Scott. Before drawing up the plans Gilbert Scott and the Infirmary's Chief Physician, Dr Charles Chadwick, visited many of the great contemporary hospitals of Europe, they were impressed by hospitals based on the pavilion plan recommended by Miss Florence Nightingale, adopted this for the new Infirmary.
It featured the latest innovations, with plentiful baths and lavatories throughout, a system of hydraulic hoists to reduce the labours of attendants and nurses. However, the high ceilings recommended by Nightingale meant that it could not be adequately heated, doors to bathrooms were two narrow to admit a wheelchair. Though completed in 1868, it had no patients for the first year. Instead it housed a temporary loan exhibition, held to recover some of the £100,000 construction costs. After half a million visitors, the profit came to only £5, it was opened on 19 May 1869 by Prince Albert, The Prince of Wales. The building was extended to designs by George Corson between 1891 and 1892; the Brotherton Wing, which now faces Millennium Square opened in 1940, the Martin and Wellcome Wings opened in the 1960s, the Worsley Building, which accommodates the Leeds Dental Institute and the Leeds School of Medicine, opened in 1979. The Clarendon Wing opened in 1984, replacing the former Leeds Women's and Children's Hospital, now houses the Leeds Children's Hospital.
The Jubilee Wing, named in celebration of the 50th anniversary of the National Health Service, which provides new Emergency Department services as well as housing regional cardiothoracic and neurosurgery facilities, opened in 1998. It provides internal links to all other sections. Though the main entrance was on Thoresby Place, the south frontage on Great George Street provided the main decorative display, with plainer more functional facades elsewhere; this Victorian Gothic frontage is in red brick with stone dressings, red granite pillars, slate roof with pinnacles and Venetian Gothic windows. The original plan follows the layout of Lariboisière Hospital in France: a'pavilion' arrangement providing cross lighting and ventilation for the wards and a Winter garden in a central glazed courtyard; the garden remains, but the glazing was removed in 1911. There are three wings North and South of this courtyard, the central South one being the George Street entrance, which has a porch in Porte-cochère style.
Inside it has a reception hall with a baronial fireplace leading to a glazed roof corridor with columns featuring carvings of medicinal plants by William Brindley and a mosaic floor. This leads to a staircase with decorative ironwork leading up to a landing with stained glass windows; this opens onto a corridor going around the garden. In the corridor is a Potts clock and just along the corridor is a chapel dedicated to Saint Luke which opened in 1869; the three wings on the south are joined by single storey closed colonnades to make the South facade. A further, but open colonnade East and another wing is a faithful copy of the original style by George Corson. On the West of Thoresby Place is the School of Medicine, an 1893 Grade II* listed building by W. H. Thorp in red brick, stone dressings and slate roofs in Perpendicular Revival style; some of the entrance hall is lined with Burmantofts Faience. In similar style is the 1897 Nurses' Home by Thorp, now north of the Brotherton Wing, facing it on the entry road from Calverley Street.
An appeal for the building of this extension was commenced in 1911. The project's general manager was F. J. Bray, its treasurer was Charles Lupton who, along with his brothers - including Alderman F. M. Lupton and his daughter Olive and her husband Richard Noel Middleton - had promised to have made donations "up to the 15th of June, 1914". F. M. Lupton's niece, Miss Elinor G. Lupton, his first cousin - Baroness von Schunck and her son-in-law Lord Airedale - gave generous donations towards the extension scheme; the Brotherton Wing on Calverley Street is in Portland Stone, in keeping with the Leeds Civic Hall on the other side of the road. It was the gift of, named after, Charles Frederick Ratcliffe Brotherton and opened in 1940. First planned in 1926, in a modern style, it has semi-circular balconies at the South End, where it was intended that patients would rest and enjoy fresh air, which did not prove to be the case because of the rise of the motor car and other pollution; this 1984 building is Leeds Children's Hospital.
It is grey slate with four storeys around a central courtyard. The Leeds Inner Ring Road runs in a tunnel underneath it; the Jubilee Wing opened in 1998 at a cost of £92 million. It is both a major expansion in the form of a north extens
An airport is an aerodrome with extended facilities for commercial air transport. Airports have facilities to store and maintain aircraft, a control tower. An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off or a helipad, includes adjacent utility buildings such as control towers and terminals. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, emergency services. In some countries, the US in particular, they typically have one or more fixed-base operators, serving general aviation. An airport serving helicopters is called a heliport. An airport for use by seaplanes and amphibious aircraft is called a seaplane base; such a base includes a stretch of open water for takeoffs and landings, seaplane docks for tying-up. An international airport has additional facilities for customs and passport control as well as incorporating all of the aforementioned elements.
Such airports rank among the most complex and largest of all built typologies with 15 of the top 50 buildings by floor area being airport terminals. The terms aerodrome and airstrip may be used to refer to airports, the terms heliport, seaplane base, STOLport refer to airports dedicated to helicopters, seaplanes, or short take-off and landing aircraft. In colloquial use in certain environments, the terms airport and aerodrome are interchanged. However, in general, the term airport may imply or confer a certain stature upon the aviation facility that other aerodromes may not have achieved. In some jurisdictions, airport is a legal term of art reserved for those aerodromes certified or licensed as airports by the relevant national aviation authority after meeting specified certification criteria or regulatory requirements; that is to say, all airports are aerodromes, but not all aerodromes are airports. In jurisdictions where there is no legal distinction between aerodrome and airport, which term to use in the name of an aerodrome may be a commercial decision.
In United States technical/legal usage, landing area is used instead of aerodrome, airport means "a landing area used by aircraft for receiving or discharging passengers or cargo". Smaller or less-developed airfields, which represent the vast majority have a single runway shorter than 1,000 m. Larger airports for airline flights have paved runways of 2,000 m or longer. Skyline Airport in Inkom, Idaho has a runway, only 122 m long. In the United States, the minimum dimensions for dry, hard landing fields are defined by the FAR Landing And Takeoff Field Lengths; these include considerations for safety margins during takeoff. The longest public-use runway in the world is at Qamdo Bamda Airport in China, it has a length of 5,500 m. The world's widest paved runway is 105 m wide; as of 2009, the CIA stated that there were 44,000 "... airports or airfields recognizable from the air" around the world, including 15,095 in the US, the US having the most in the world. Most of the world's large airports are owned by local, regional, or national government bodies who lease the airport to private corporations who oversee the airport's operation.
For example, in the United Kingdom the state-owned British Airports Authority operated eight of the nation's major commercial airports – it was subsequently privatized in the late 1980s, following its takeover by the Spanish Ferrovial consortium in 2006, has been further divested and downsized to operating just Heathrow now. Germany's Frankfurt Airport is managed by the quasi-private firm Fraport. While in India GMR Group operates, through joint ventures, Indira Gandhi International Airport and Rajiv Gandhi International Airport. Bengaluru International Airport and Chhatrapati Shivaji International Airport are controlled by GVK Group; the rest of India's airports are managed by the Airports Authority of India. In Pakistan nearly all civilian airports are owned and operated by the Pakistan Civil Aviation Authority except for Sialkot International Airport which has the distinction of being the first owned public airport in Pakistan and South Asia. In the United States, commercial airports are operated directly by government entities or government-created airport authorities, such as the Los Angeles World Airports authority that oversees several airports in the Greater Los Angeles area, including Los Angeles International Airport.
In Canada, the federal authority, Transport Canada, divested itself of all but the remotest airports in 1999/2000. Now most airports in Canada are owned and operated by individual legal authorities or are municipally owned. Many U. S. airports still lease part or all of their facilities to outside firms, who operate functions such as retail management and parking. In the U. S. all commercial airport runways are certified by the FAA under the Code of Federal Regulations Title 14 Part 139, "Certification of Commercial Service Airports" but maintained by the local airport under the regulatory authority of the FAA. Despite the reluctance to privatize airports in the US, the government-owned, contractor-operated arrangement is the standard for the operation of commercial airports in the rest of the world. Airports are divided into airside areas; the landside area is open to the public, while access to the airside area is controlled. The airside area includes all parts of the airpo
An oil platform, offshore platform, or offshore drilling rig is a large structure with facilities for well drilling to explore, extract and process petroleum and natural gas which lies in rock formations beneath the seabed. In many cases, the platform contains facilities to house the workforce as well. Most oil platforms engage in activities on the continental shelf, though they can be used in lakes, inshore waters and inland seas. Depending on the circumstances, the platform may be fixed to the ocean floor, may consist of an artificial island, or may float. Remote subsea wells may be connected to a platform by flow lines and by umbilical connections; these sub-sea solutions may consist of one or more subsea wells, or of one or more manifold centres for multiple wells. Offshore drilling presents environmental challenges, both from the produced hydrocarbons and the materials used during the drilling operation. Controversies include the ongoing U. S. offshore drilling debate. There are many different types of facilities from which offshore drilling operations take place.
These include bottom founded drilling rigs, combined drilling and production facilities either bottom founded or floating platforms, deepwater mobile offshore drilling units including semi-submersibles and drillships. These are capable of operating in water depths up to 3,000 metres. In shallower waters the mobile units are anchored to the seabed, however in deeper water the semisubmersibles or drillships are maintained at the required drilling location using dynamic positioning. Around 1891, the first submerged oil wells were drilled from platforms built on piles in the fresh waters of the Grand Lake St. Marys in Ohio; the wide but shallow reservoir was built from 1837 to 1845 to provide water to the Miami and Erie Canal. Around 1896, the first submerged oil wells in salt water were drilled in the portion of the Summerland field extending under the Santa Barbara Channel in California; the wells were drilled from piers extending from land out into the channel. Other notable early submerged drilling activities occurred on the Canadian side of Lake Erie since 1913 and Caddo Lake in Louisiana in the 1910s.
Shortly thereafter, wells were drilled in tidal zones along the Gulf Coast of Texas and Louisiana. The Goose Creek field near Baytown, Texas is one such example. In the 1920s, drilling was done from concrete platforms in Lake Maracaibo, Venezuela; the oldest offshore well recorded in Infield's offshore database is the Bibi Eibat well which came on stream in 1923 in Azerbaijan. Landfill was used to raise shallow portions of the Caspian Sea. In the early 1930s, the Texas Company developed the first mobile steel barges for drilling in the brackish coastal areas of the gulf. In 1937, Pure Oil Company and its partner Superior Oil Company used a fixed platform to develop a field in 14 feet of water, one mile offshore of Calcasieu Parish, Louisiana. In 1938, Humble Oil built a mile-long wooden trestle with railway tracks into the sea at McFadden Beach on the Gulf of Mexico, placing a derrick at its end - this was destroyed by a hurricane. In 1945, concern for American control of its offshore oil reserves caused President Harry Truman to issue an Executive Order unilaterally extending American territory to the edge of its continental shelf, an act that ended the 3-mile limit "freedom of the seas" regime.
In 1946, Magnolia Petroleum drilled at a site 18 miles off the coast, erecting a platform in 18 feet of water off St. Mary Parish, Louisiana. In early 1947, Superior Oil erected a drilling/production platform in 20 ft of water some 18 miles off Vermilion Parish, Louisiana, but it was Kerr-McGee Oil Industries, as operator for partners Phillips Petroleum and Stanolind Oil & Gas, that completed its historic Ship Shoal Block 32 well in October 1947, months before Superior drilled a discovery from their Vermilion platform farther offshore. In any case, that made Kerr-McGee's well the first oil discovery drilled out of sight of land; the British Maunsell Forts constructed during World War II are considered the direct predecessors of modern offshore platforms. Having been pre-constructed in a short time, they were floated to their location and placed on the shallow bottom of the Thames and the Mersey estuary. In 1954, the first jackup oil rig was ordered by Zapata Oil, it was designed by R. G. LeTourneau and featured three electro-mechanically-operated lattice type legs.
Built on the shores of the Mississippi river by the LeTourneau Company, it was launched in December 1955, christened'Scorpion'. The Scorpion was put into operation in May 1956 off Port Aransas, Texas, it was lost in 1969. When offshore drilling moved into deeper waters of up to 30 metres, fixed platform rigs were built, until demands for drilling equipment was needed in the 100 feet to 120 metres depth of the Gulf of Mexico, the first jack-up rigs began appearing from specialized offshore drilling contractors such as forerunners of ENSCO International; the first semi-submersible resulted from an unexpected observation in 1961. Blue Water Drilling Company owned and operated the four-column submersible Blue Water Rig No.1 in the Gulf of Mexico for Shell Oil Company. As the pontoons were not sufficiently buoyant to support the weight of the rig and its consumables, it was towed between locations at a draught midway between the top of the pontoons and the underside of the deck, it was noticed that the motions at this draught were small, Blue Water Drilling and Shell jointly deci
