This work reports on the results of development of a tension leg platform (TLP) suitable for the North Sea, designed for the production of 100,000 barrels of oil per day (BOPD). The development was carried out in collaboration with the American engineering company FLUOR Inc. of Houston, Texas, which was responsible for the basic design, the assessment of the movement behaviour and the design of the riser, tendons and the floor anchoring, using their already available programs. The design of a process unit on the deck of the TLP authorised for the North Sea was particularly important and the excellent expert knowledge of FLUOR was the precondition for this. The whole plant was to be tested and approved by the Det Noske Veritas (DnV), who received a subcontract in the context of the project. BLOHM + VOSS AG (B+V) were responsible for the arrangement of the process, drilling and living quarters on the TLP and for the development of a safety strategy in discussion and in agreement with the requirements of the DnV. B+V, using the knowledge of strength and fatigue strength of CONOCOS Hutton, designed the steel structure of the TLP. Special attention was paid to clear classification of the bracings and the unambiguous transfer of forces at the critical highly-stressed places, such as the front/pillar transition or the deck/pillar transition, in order to reduce the building cost and achieve a high degree of use of the material. B+V also designed the living quarters of the TLP, a hotel for more than 200 people, which is lifted onto the TLP in one piece and examined the site requirements and course of construction of a TLP and the floating process of connection of the platform deck and substructure. B+V also participated in determining the total cost. (orig.).
