OPTIMISATION OF OFFSHORE INSTALLATION STRATEGY BY SIMULATION

The STAR (Slim Tripod Adapted to Rig) concept was developed in order to meet the requirements for a small multi-well platform suitable for shallow water, especially for marginal fields, where a stepwise development approach is desirable due to e.g. reservoir uncertainties. As a number of crane barge contractors available on the market is limited, the aim was to develop a platform concept, which apart from conventional installation methods also would allow for installation by a medium size drilling rig (jack-up) in connection with drilling of the wells. However, prior to the actual installation it was agreed to try out the hitherto unproven method in a real-time simulator. The paper outlines the general results obtained from the simulation programme, and it documents in particular the agreement between computed and measured (full-scale) barge motions as well as the value of the training sessions.
