Over the past thirty years pile founded steel jacket-type platforms (commonly referred to as fixed platforms) have represented the most common structural solution for offshore structures and in particular the offshore oil and gas industry's drilling and production facilities. The need to move into deeper waters, technological advancements, ever-growing expertise, more sophisticated analytical techniques and faster and larger computers have pushed the state-of- the-art further and further. Today the tallest steel jacket. Shells Cognac platform, stands in 1050 feet of water in the Gulf of Mexico. There are various indications that with the present technology, water depths much beyond 1000 feet may require an altogether different approach. |
