Abstract: An offshore structure for deploying and retrieving underwater electrical power generators that converts energy derived from water currents into electrical energy. The offshore structural platform includes a pair of vertical guide rails to guide a propulsion device lowering said generator underwater onto a seabed propulsion device. The seabed propulsion device is engaged on an underwater seabed rail system and transports the generator onto one of many unique frames specifically designed to support underwater generators. Securing devices are utilized to ensure the generators remain anchored to each propulsion device and to the unique frame. Rail transferring elements are also utilized for a smooth and safe transition during the transport process.

Abstract: A transshipper for floating on water comprises a pair of elongate buoyant vessels arranged in parallel spaced relationship for receiving a feeder barge to be unloaded between the vessels. The platform is supported by the buoyant vessels in a raised position above the buoyant vessels. A transfer conveyor supported by the buoyant vessels extends transversely of the buoyant vessels in a raised position above the buoyant vessels. A first lifting conveyor is suspended from the platform and is movable longitudinally of the transfer conveyor for raising material to be unloaded from a feeder barge located between the buoyant vessels and for depositing the material onto the transfer conveyor. A second lifting conveyor is provided for receiving material from the transfer conveyor and an unloading boom is provided for receiving the material from the second lifting conveyor and for delivering the material to a receiving vessel located alongside one of the buoyant vessels.
