VESSEL FOR TRANSPORTING WIND TURBINES AND METHODS THEREOF
First Claim
1. ) A vessel comprising:
- a hull having a hull periphery, wherein the hull periphery has a bow, a center section, a transom, an extended transom, a bow sloped section between the bow and the center section, and a transom sloped section between the transom and the center section, and the transom is wider, along the vertical axis, than the bow, and the bow and transom are at least half as deep as the center section;
at least two rear jack-up legs movably attached to the hull;
at least one forward jack-up leg movably attached to the hull;
a powered jacking mechanism connected to each of the jack-up legs for elevating and lowering each jack up leg relative to the hull between elevated and lowered positions;
at least two rear azimuthing thrusters affixed to a lower side of the transom;
at least one front azimuthing thruster affixed to a lower side of the bow;
at least four wind-turbine-column foundations; and
at least two wind-turbine-blade brackets individually affixed to the side of the transport vessel.

Abstract
A vessel having the capability of storing, transporting, and installing between one and ten wind turbines is provided. Such a vessel includes a hull having a hull periphery. The vessel further includes at least two rear jack-up legs, and at least one forward jack-up leg, movably attached to the hull, as well as a jacking mechanism connected to each of the jack-up legs for elevating and lowering each jack-up leg relative to the hull between elevated and lowered positions. The vessel also includes at least two rear azimuthing thrusters affixed to a lower side of the transom; and at least one front azimuthing thruster affixed to a lower side of the bow. The vessel further includes at least four, preferably at least six, wind-turbine-column foundations, and at least two wind-turbine-blade brackets individually mounted to the side of the transport vessel.
