Abstract
The offshore jack-up has a hull and a plurality of moveable legs engageable with the seafloor. The offshore jack-up is arranged to move the legs with respect to the hull to position the hull out of the water. The method comprises securing the vessel with respect to the hull of the offshore jack-up when the hull is positioned out of the water and the legs engage the seafloor. A lifting mechanism mounted on the offshore jack-up engages with a cargo carrying platform positioned on the vessel. The platform is lifted with the lifting mechanism between a first position on the vessel and a second position clear of the vessel.
Claims20
A cargo carrying platform to carry a plurality of separate wind turbine components including at least one wind turbine blade, and to transfer the plurality of separate wind turbine components between a vessel and an offshore jack-up, the cargo carrying platform comprising:
- a platform base configured to engage with the plurality of separate wind turbine components, the platform base being further configured to be releasably secured to the vessel;
- a frame mounted to a periphery of the platform base, the frame configured to at least partially surround the plurality of separate wind turbine components;
- at least one engagement position, the at least one engagement position configured to engage with a lifting mechanism mounted on the offshore jack-up, the lifting mechanism configured to engage and lift the cargo carrying platform between a first position on the vessel and a second position clear of the vessel;
- and
- an elevated fastening portion mounted above the platform base, the elevated fastening portion configured to secure the at least one wind turbine blade.
A method of loading a plurality of separate wind turbine generator components on a vessel, the plurality of separate wind turbine generator components including at least one wind turbine blade, the method comprising:
- loading the plurality of separate wind turbine generator components on a cargo carrying platform having a frame mounted to a periphery of a platform base, the frame configured to at least partially surround the plurality of separate wind turbine generator components and an elevated fastening portion mounted above the platform base arranged to secure the at least one wind turbine blade;
- and
- loading the cargo carrying platform on the vessel.
A cargo carrying platform to carry a plurality of separate wind turbine components including at least one wind turbine blade, and to transfer the plurality of separate wind turbine components between a vessel and an offshore jack-up, the cargo carrying platform comprising:
- a platform base configured to engage with the plurality of separate wind turbine components, the platform base further configured to be releasably secured to the vessel;
- an elevated fastening portion mounted above the platform base, the elevated fastening portion configured to secure the at least one wind turbine blade;
- at least one sea fastening configured to releasably secure the platform base to the vessel;
- and
- at least one securing mechanism configured to releasably secure the plurality of separate wind turbine components to the platform base such that the plurality of separate wind turbine components are secured to the platform base when the cargo carrying platform is lifted from the vessel.
