Concept Design of a Station Keeping Vessel Dedicated to Maintenance of the Far Shore Wind Farm

Abstract

The thesis together with the attached General Arrangement drawing is focused on the concept design of a station keeping vessel Mauric Far shore Wind farm Station Keeping Vessel (MFWSV) dedicated to maintenance of offshore wind farms, with an integrated friendly environment energy architecture. The design was developed during the three-month research program at BUREAU MAURIC, Nantes, France. The offshore wind farm supply vessel coupled with the green energy propulsion system and met all IMO (International Maritime Organization) regulations on offshore vessels.

The report is divided into 3 parts. Part 1 describes the essential project background, design assumption, choice of specification and theoretical background, while Part 2 goes into more details on the procedure of the project MFWSV, including the general arrangement, calculation, propulsion system and dynamic positioning system of the vessel. Part 3 relates to research and introduction of special systems in this vessel.

The MFWSV is a 75m monohull designed to operate in far shore of Southern North Sea wind farms where significant wave heights reach to 3.25 meters and the water depth is about 50 m. The vessel varies from the current wind farm support vessels and will provide accommodation, safer transfer for technicians and warehouse facilities during the service period. In the same time, it is designed for ease of maintenance as it has a diesel - electric propulsion advantageous for the Dynamic Positioning System to avoid necessity of maintenance in the rough seas and longer transits.

AUTOCAD computer system was used for design of general arrangement of the ship, MS Excel to estimate weight of vessel and electric consumption in different statue of the vessel propulsion system.
