A feeder vessel for the onshore-to-offshore transport of elongate wind turbine objects with a motion compensating carrier assembly having a motion compensated platform for receiving and retaining the elongate object, and a motion compensation mechanism. The motion compensation mechanism includes extendable actuators which passively compensate motions of the platform out of a neutral position, and winches driving carrier cables such that traction by the respective carrier winch counteracts an extension of at least one of the carrier actuators. The winches are embodied as active motion compensation winches to compensate movements of the platform.

A modular spreader structure (10) for use in offshore lifts comprises a plurality of elongate tubular elements (26, 22) made primarily of composite material. Primary tubular elements (26) each comprise an axial coupler formation (28) for end-to-end coupling with a complementary axial coupler formation of another primary tubular element, aligned on a common longitudinal axis. The adjoining primary tubular elements are interengageable by longitudinal overlap between male and female axial coupler formations. Secondary tubular elements (22) each comprise a node connector (30) that is configured for attachment to the structure at an orientation inclined relative to the common longitudinal axis of the primary tubular elements. In particular, the secondary tubular elements can be attached to an outer surface of one of the primary tubular elements.

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 moving at least a portion of a vessel underneath the hull of the offshore jack-up or within a cut-out of the hull when the hull is positioned out of the water and the legs engage the seafloor. A stabilizing mechanism mounted on the jack-up is engaged against the vessel. The stabilizing mechanism is pushed down on the vessel to increase the buoyant force acting on the vessel.

This invention provides a method and apparatus for transporting marine fuel by rail car directly to a fueling vessel, by loading rail cars loaded with marine fuel onto a specially equipped roll-on/roll-off rail barge and transporting the barge by towboat to a mooring, where it is moored/secured in position, after mooring the barge will have the capability for offloading marine fuel from its rail cars via a barge-included distribution system to fuel a vessel. The barge may operate and be regulated as a fuel terminal when secured to the mooring.

A marine emergency rescue transfer system includes a water navigation robot. An attracting device configured to attach and fix with an accident ship is installed on one side of the water navigation robot. An automatic lifting device is installed on the water navigation robot. A fixing sealing device is installed on the automatic lifting device. The automatic lifting device is installed on the automatic lifting device. The fixing sealing device includes a box body and a vacuum pump. The box body defines a cavity. The vacuum pump is configured to pump air or water in the cavity, so the box body is fixed on the accident ship through atmospheric pressure or water pressure. The rescue devices are placed in the fixing sealing device. The remote control grippers are installed on the automatic lifting device. The remote control grippers are configured to grip the rescue devices for transfer operation.
