No-Excess Block Construction in Oil Drilling Platform Sevan Driller

Abstract:

Article Preview

The technique of hull block accuracy control is the main concern for modern shipbuilding. The method of no-excess block construction is introduced in Sevan Driller, the world’s first cylindrical ultra-deep offshore drilling platform. According to the structural characteristics of the drilling platform and production capacity, the partition and construction programs of the hull blocks are proposed. Modeling and drawing for platform in the design stage is analyzed. In the manufacturing stage, the factors affecting the block accuracy include plate-cutting, plate alignment, marking, assembling and welding. Additionally, the range of accuracy controlling aspect and compensation values are confirmed. The application of no-excess block construction in this drilling platform results in the improved quality of the drilling platform, reduced shipbuilding costs and the shortened shipbuilding cycle.
