Large Spar Drilling and Production Platforms for Deep Water Oil and Gas

A “spar” is a term for a long slender pole commonly used in sailing vessels as booms or masts. In the context of this book, spars are floating structures that are characterized by their deep drafts and long vertical hull forms. Spar platforms have been used for offshore oil and gas operations for a number of years. The first application was a storage spar, “Brent,” installed in the North Sea in the 1960s. Spars were introduced for production, drilling, and workover operations in the 1990s. They remain one of the few hull forms that can support top-tensioned risers for drilling and production in ultra-deep water.
