The present invention relates to a method for riser string handling on an offshore drilling vessel (1), the offshore drilling vessel comprising a multiple firing line hoist system, a riser tensioner system (50) arranged in the second firing line, and a suspended riser transfer device (60). The method comprising the steps of lowering a riser string in the first firing line, and simultaneously assembling and preparing a riser tensioner system in the second firing line, wherein the riser hang-off assembly displaces the riser string, leaving the top end of the riser string exposed, from the first firing line to the second firing line to be connected to the riser tensioner system.

Disclosed herein is a marine vessel, which in one example comprises a substantially continuous deck. Also disclosed is an example with a plurality of parallel longitudinally aligned channels extending from the forward deck to the aft deck. The vessel having a vessel cabin resting on and longitudinally movable upon the deck. The vessel cabin in one example having a plurality of rolling wheels attached thereto; wherein the rolling wheels roll upon the deck and allow longitudinal movement of the vessel cabin between the aft region and the forward region. A drive unit (motor) may be provided. The drive unit optionally mounted to the cabin and in one example having a drive wheel mounted to the drive unit and configured to rotate the drive wheel. The drive wheel(s) contacting the deck such that rotation of the drive wheel repositions the cabin between the aft region and the forward region.

An extendable and retractable lower deck for a watercraft is attached to and supported by one or more amidships hulls. The lower deck and hulls slide between an extended position and a stowed position on rails that are secured to the underside frame of the main, upper deck that is supported by abeam hulls. When fully extended, the extendable deck remains attached to the watercraft. A rotatable gate positioned within the lower hull can be used for improved accessibility to and from the water; the gate is stowed when its distal end is in the raised position and is deployed when its distal end extends below the bottom side of the hull into the water in the lowered position. Laterally expandable panels in the lower deck provide increased width, and other accessories used with the watercraft can be contained in one or more storage holds in the amidships hull.

A manual and submersible auxiliary swim platform for a vessel having a main aft platform, the main aft platform having a recessed area for receiving the auxiliary swim platform. A pair of bracket assemblies secure the auxiliary platform to the main aft platform, and both bracket assemblies have a first bracket member, a second bracket member, and a detent bushing. The detent bushing is interposed and secured to the first and second bracket members at a common end. The detent bushing limits rotational and pivotal movement of the bracket assemblies in conjunction with a contact tab, pin and channel design of the bracket assemblies.

An aquatic vessel, illustratively a pontoon boat including a thruster system is disclosed. The aquatic vessel executes a process to automatically position the aquatic vessel relative to a target location such as a mooring implement. Exemplary mooring implements include a dock, a slip, or a lift.

A cruise system using mobility vehicles, may include a cruise ship having a cabin space used as a cabin when a mobility vehicle is aboard. A mobility vehicle is configured to board or disembark the cruise ship, and when aboard, park in the cabin space to serve as a cabin. A connector electrically connects the mobility vehicle and the cruise ship to enable power exchange or data communication between the mobility vehicle and the cruise ship.
