World's first concrete TLP takes shape off Norway
The world's first concrete tension leg platform (TLP) is being assembled offshore Norway for development of Heidrun field by Conoco Norway Inc. to meet a target for first oil production on Aug. 1, 1995. Development of Heidrun fields is in many ways a frontier project. It lies in 350 m of water in the Norwegian Sea off central Norway and is the most northerly development in Norwegian waters. It sees introduction of the concrete floater and the use of titanium drilling risers. It is the first development offshore Norway to utilize off loading of produced oil directly into shuttle tankers without storage. Installation methods for Heidrun's topsides and foundations were designed to avoid the requirement for heavy lift vessels. And concrete was used for the first time to make module support beams in the TLP hull. The paper describes the exploration history of the field, TLP details, marine operations at Heidrun, and contracts.
