![]() ![]() Furthermore, NC will perform all marine operations related to the substructure. This comprises the complete delivery of the hull with two module support beams (MSB), including all mechanical outfitting. Norwegian Contractors a.s (NC) is undertaking the Engineering, Procurement, Construction and Installation (EPCI) contract for the Heidrun TLP substructure. The more » Heidrun TLP will be the northern most located platform in the North Sea when installed at Haltenbanken in 1995. The TLP will be moored by 16 steel tethers, arranged in groups of four per corner, which secure the substructure (hull) to the concrete foundations. The field is developed by means of a concrete Tension Leg Platform (TLP) by Conoco Norway Inc. The Heidrun Field is located in 345 m water depth in the northern part of the Haltenbanken area, approximately 100N miles from the west coast of mid-Norway. The focus will although be on the concrete substructure. This paper gives a summary of the Heidrun substructure including tethers and foundations. Statoil believes it can fill the gap from existing fields in Norwegian waters. Sleipner was to have begun deliveries to a consortium of continental gas companies in October 1993. The Sleipner setback forces state owned Den norske stats oljeselskap AS (Statoil) to cast around for supplies. With European gas demand sharply increasing, Norway is under pressure to increase output from new fields in the mid to late 1990s. Norwegian oil more » production has been hovering just below 2 million b/d since the beginning of this year, making Norway the North Sea's largest producer, a position formerly held by the U.K. Aker Oil and Gas, a leading offshore firm, says the country's construction industry will be working at capacity for the next 4 years. Currently, 10 oil and gas fields are under development, and several projects are on the drawing board. The accident, a blow to Norway's gas sales program in Europe, came with offshore activity in the Norwegian North Sea moving into a new boom period. This paper reports on Norway's buoyant offshore industry that was stunned when the concrete substructure for Sleipner natural gas field's main production platform sank in the Grandsfjord off Stavanger late last month. This will use conventional production technology, although the possibility of a concrete treatment platform has not been ruled = , Also in the Norwegian North Sea, companies involved in the Sleipner gas development project agreed to seek approval for the $1.77 billion, first phase development phase of West Sleipner reserves beginning in 1996. In addition, a group led by Norsk Hydro Produksjon AS, Oslo, chose a concrete floating production platform as the basis for a $2.42 billion development of the oil province in Troll gas field in the North SEa. ![]() ![]() As part of a $3.5 billion project, it will be installed in the Conoco group's Heidrun oil and gas field in the Haltenbanken area of the Norwegian Sea off mid-Norway. let a $350 million contract for construction of the world's first concrete hull, tension leg platform (TLP) to Norwegian Contractors, Stavanger. ![]() This paper reports on development plans for two fields off Norway that have given a boost to use of concrete for the construction of floating production facilities. ![]()
