North Sea, Norway, Europe.
Imagine having operations in 36 countries around the world. What type of infrastructure would you need? What communication channels are essential? How do you manage people and results? How would you guarantee peak performance and meet budgets and deadlines? These have been the questions and challenges of the energy industry for the last 40 years, and no company has been more effective at answering these questions than the Norwegian oil-and-gas giant Statoil, which has become a world energy leader in the game of growth, while still having the presence of mind to be sustainable conscious.
Statoil Troll-A Platform: The Largest Object Ever Moved by Mankind
The Troll A platform is an offshore natural gas platform in the Troll gas field off the west coast of Norway. At 1.2 million ton ballasted under tow, 472 meters high, with underwater concrete structure at 369 meters, and dry weight of 656,000 tons, the Troll A platform is a majestic piece of design and construction. Not only is Troll A among the largest and most complex engineering projects in history, it is the largest object ever to be moved by man across the surface of the Earth.
Statoil Troll-A Platform: The Largest Object Ever Moved by Mankind.
The Troll A platform is a condeep offshore natural gas platform in the Troll gas field off the west coast of Norway. It is the tallest structure that has ever been moved to another position, relative to the surface of the Earth, and is among the largest and most complex engineering projects in history. The platform was a worldwide sensation when it was towed into the North Sea in 1996, where it is now operated by Statoil.
Oil has made the Troll gas field to shelf giant, larger than the number two and three, Ekofisk and Statfjord, combined. The extraction of oil from the thin layers of Troll is one of the Norwegian shelf biggest success stories, not only technologically but also in resource management and value creation on the shelf. The Norwegian Petroleum Directorate (NPD) has played a crucial role in this process, and still do. The Troll field lies in the northern part of the North Sea, around 65kms west of Kollsnes, near Bergen. The enormous gas reservoirs lying 1,400 meters below sea level are expected to produce for at least another 70 years.
The platform stands on the sea floor 303 meters below the surface of the sea and one of the concrete cylindrical legs has an elevator that takes over nine minutes to travel from the platform above the waves to the sea floor. The walls of Troll A's legs are over 1 meter thick made of steel reinforced concrete formed in one continuous pour. The four legs are joined by a "Chord shortener", a reinforced concrete box interconnecting the legs, but which has the designed function of damping out unwanted potentially destructive wave-leg resonances. Each leg is also sub-divided along its length into compartments a third of the way from each end which act as independent water-tight compartments. The legs use groups of six 40 meters tallvacuum-anchors holding it fixed in the mud of the sea floor. In 1996 the platform set the Guinness World Record for 'largest offshore gas platform'. The title now belongs to the Petronius Platform in the Gulf of Mexico which stands 2,000 feet (610 m) above the ocean floor.
In 1996 the platform set the Guinness World Record for 'largest offshore gas platform'. In 2006, the 10th anniversary of Statoil's operatorship of Troll gas production was celebrated with a concert by Katie Melua held at the base of the Troll A platform. As well as entertaining the workers on the rig, the concert set a new world record for the deepest underwater concert at 303 meters below sea level.
On 2 October 2006, Melua entered the Guinness Book of Records for playing the deepest underwater concert 303 metres below sea level on the Norwegian Statoil's Troll A platform in the North Sea. Melua and her band underwent extensive medical tests and survival training in Norway before flying by helicopter to the rig. Melua later described achieving the record as "the most surreal gig I have ever done". Melua's concert is commemorated in the DVD release Concert Under the Sea, released in June 2007.
