Application of a Tripod Tower Platform Accommodating 4 to 6 Conductors for Mini-Satellite Developments.

摘要

The objective of the study was to investigate the application of a Tripod Tower Platform (TTP) for mini-satellite developments. The platform has to accomodate 4 to 6 vertical conductors and will be placed in 26 m waterdepth in the K15-area. The study was initiated by and executed in cooperation with the Nederlandse Aardolie Maatschappij (NAM) b.v. First the basis for design was determined, in which the most important subject is the NAM mini-satellite concept. The concept implies that no gas-processing will take place on the platform, that it is unmanned, and only wireline operations are to be executed from the platform itself. Secondly a layout for the platform was made. This results in 3 alternatives regarding the layout of the column in the substructure. The third part of the study is the calculation of the costs, regarding materials, fabrication and installation, and to compare the costs of the designed platform with the NAM mini-satellite.
