Transport Vessels for Floating Wind

Abstract

Floating wind turbine construction is a large logistical exercise. The naval architecture requirements are described for a semi-submersible substructure. Large heavy transport vessels are required to transport the substructures from the shipyard to the fit-out quay. Specialized cargo ships transport turbine blades and nacelles from the dockside factory to the fit-out quay. General cargo ships move the anchors and associated equipment to the mooring assembly yard. The transport vessels for the substructure may be powered, Heavy Transport Vessels (HTV) or non-powered cargo barges. Intact stability, both GM and GZ curves, and damage stability need to be considered. This article outlines the loadout, ocean transport and float off restrictions of the substructure.

The article discusses the naval architecture requirements for transport vessels and will discuss intact stability, damage stability, motions, accelerations, bending moments, and sea fastenings. Constraints such as local width, overhead cables, bridges, and water depths are considered
