Abstract: A method of securing a vessel (206) with an offshore jack-up (100). The offshore jack-up (100) has a hull (102) and a plurality of moveable legs (104a, 104b, 104c, 104d) engageable with the seafloor. The offshore jack-up (100) is arranged to move the legs (104a, 104b, 104c, 104d) with respect to the hull to position the hull (102) out of the water. The method comprises moving at least a portion of a vessel underneath the hull (102) of the offshore jack-up or within a cut-out (400) of the hull (102) when the hull is positioned out of the water and the legs (104a, 104b, 104c, 104d) engage the seafloor. A stabilizing mechanism (502, 504, 506, 508, 510, 512) mounted on the offshore jack-up (100) is engaged against the vessel (206). The stabilizing mechanism is pushed down on the vessel to increase a buoyant force acting on the vessel.

Abstract: A semi-submersible service vessel (100) for a floating installation (102) has a hull (104) and a ballasting system. The ballasting system is arranged to selectively lower the hull (104) to a first draft and raise the hull (104) to a second draft. The second draft is smaller than the first draft. At least one submersed elongate lifting fork is fixed to the hull (104) and is configured to extend across the underside of the floating installation (102) and engage the underside of the floating installation (102) when the hull (104) is raised from the first draft to the second draft. Wherein the at least one lifting fork is arranged to lift the entire floating installation (102) when the hull (104) is raised from the first draft to the second draft, and a method of servicing a floating installation (102) with a semi-submersible service vessel (100).

Abstract: A method of supplying a load between a vessel and an offshore jackup (100). The offshore jackup has a hull (102) and a plurality of moveable legs (104) 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 (406) mounted on the offshore jack-up (100) engages with a cargo carrying platform (228) 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.
