Abstract

An optimal ship for installation of offshore wind turbines should ideally provide the following three main features:
•a crane, which can handle heavy items and place them at a position high above the sea level;
•a jacking system, which is stable and able to operate at large water depths and reasonably high seas; and
•a large free deck area for stowage of wind turbine components.

The latter point, a large free deck area, is most often obstructed by mooring equipment, air pipes, rescue equipment etc. at various positions on the vessels deck and in particular along its sides. One possibility for improvement is to build a so called trunk above the deck and extend the trunk to the vessel's sides by means of beams and stanchions thereby a completely free area is established for stowage of the wind turbine components. The combination of an "elevated" deck and installation of beams extending to the ship's side, where the beams are supported by stanchions provides several benefits, including:
•A larger area for stowage of wind turbine components, i.e. increased loading capacity and better stowage arrangement;
•a free passage along the ship's sides; and
•good and readily accessible space for rescue means, mooring equipment, etc.

Arrangement of vessel for improved stowage of wind turbine components

Abstract:

An optimal ship for installation of offshore wind turbines should ideally provide the following three main features:


• a crane, which can handle heavy items and place them at a position high above the sea level;


• a jacking system, which is stable and able to operate at large water depths and reasonably high seas; and


• a large free deck area for stowage of wind turbine components.

The latter point, a large free deck area, is most often obstructed by mooring equipment, air pipes, rescue equipment etc. at various positions on the vessels deck and in particular along its sides. One possibility for improvement is to build a so called trunk above the deck and extend the trunk to the vessel's sides by means of beams and stanchions thereby a completely free area is established for stowage of the wind turbine components.

The combination of an "elevated" deck and installation of beams extending to the ship's side, where the beams are supported by stanchions provides several benefits, including:


• A larger area for stowage of wind turbine components,


i.e. increased loading capacity and better stowage arrangement;


• a free passage along the ship's sides; and


• good and readily accessible space for rescue means, mooring equipment, etc.

Alternative to trunk: cargo-hold for wind turbine components and/or wells for tower sections
