Supporting clients as they pioneer novel installation techniques

摘要

To accommodate the transport and installation of the 10MW-plus turbines, larger jack-up vessels are being designed. Besides the traditional resistance and propulsion, seakeeping and dynamic positioning analyses, leg load and operability analysis are vital for the critical jack-up phase of the operation. Feeder barge concepts have also been on the drawing board for many years. These barges can be floating or rigidly connected to the installation vessel. However, the challenge for the floating barges is to deal with the motions of the barge, while lifting components from the deck. For the rigid connection alternative, the mam challenges are the impacts between the barge and installation vessel during connection and the wave loads on both vessels. MARIN performs numerical motion analyses and concept model tests to determine the feasibility and operability of feeder barge solutions.
