Abstract
Marine pump vessels and wing fluidizer support vessels, and methods of using same. Wing fluidizer support vessels are configured to deploy a wing fluidizer including thrusters capable of fluidizing sediments from a first seabed location and moving it to a second seabed location. Pump vessels include one or more pumps deployable from a separate vessel and stowable thereon.
Claims14
A subsea sediment fluidizer support vessel, comprising:
- a) a modular, generally rectangular hull comprising a plurality of box-shaped float modules coupled together that is configured to be disassembled and transported on one or more trucks or shipping containers, the modular hull comprising a deck, a bow, a stern, a port side, and a starboard side;
- b) port and starboard telescoping jib booms secured to the hull and configured to support and move a wing fluidizer between stowed and deployed positions, the wing fluidizer having one or more thrusters for moving sediment;
- c) port and starboard electric motorized trolleys movably secured to the respective port and starboard telescoping jib booms to assist in moving the wing fluidizer;
- d) port and starboard slave trolleys movably secured to the respective port and starboard telescoping jib booms to assist in moving the wing fluidizer;
- and
- e) electric wire hoists connected to the port and starboard slave trolleys and configured to lift, lower, and adjust attitude of the wing fluidizer.
