A buoyant offshore renewable energy system mounting platform is provided for positioning a renewable energy device in a body of water, the body of water comprising a surface and a bed, the platform comprising a framework, comprising at least three vertexes, and at least one mooring member for positioning the platform relative to the surface and bed of the body of water. Each of the at least three vertexes having at least one buoyancy member. The buoyancy member preferably comprising a plurality of buoyancy units wherein at least one of the buoyancy members comprises a renewable energy device selected from: a renewable energy convertor; a renewable energy harnessing apparatus; a renewable energy processing apparatus; a renewable energy storing apparatus; a renewable energy data capture apparatus; a data storing apparatus.

A system for converting fluid flow into electricity. The system has an arm assembly with four floats that rotate around a center float. The floats on the arm assembly are all provided with impellers that turn one half revolution for every one revolution of the arm assembly. This slow rotation maintains the impellers at the optimal angle to convert the flow of the water current into rotational motion of the arm assembly, regardless of the orientation of the arm assembly. The arm assembly is coupled to an electric generator provided on the center float that converts torque generated by the arm assembly into electric power that may either be stored on an on-board battery or transmitted by wire for use elsewhere.

A wind-wave-resistant floating offshore photovoltaic device includes a photovoltaic array and a mooring unit; the mooring unit used for limiting the position of the photovoltaic array is arranged on two sides and the head of the photovoltaic array, the photovoltaic array includes a breaking-wave base device arranged on a wave facing face, resonance wave absorbing floating body units arranged in a middle and common floating body units arranged on a wave shielding face, and the whole formed by connecting the plurality of resonance wave absorbing floating body units is connected to the breaking-wave base device by means of rubber ring type connectors.

A suspension system for supporting a body relative to at least four points, including: a respective front left, front right, back left and back right support arrangement between the respective point and the body, each respective support arrangement including a respective resilience arrangement and a respective control ram, each respective control ram including a respective compression chamber forming at least part of a respective compression control volume; a control arrangement including a first and a second diagonal reversible pump for displacing fluid between diagonally opposite compression control volumes. Each respective resilience arrangement can include a respective damping arrangement to restrict and/or selectively prevent compression and/or expansion of at least a portion of the respective resilience arrangement. Each respective control ram can further include a respective rebound chamber, the front control rams being cross connected and the back control rams being cross connected.

A chassis module for a vessel, the chassis module having: a frame; a left linkage arrangement including at least one left hull connection and configured to movably couple the frame to at least one left hull when the left hull connection is connected to the left hull; a right linkage arrangement including at least one right hull connection and configured to movably couple the frame to at least one right hull when the right hull connection is connected to the right hull; at least one left support mount and at least one right support mount for respectively connecting to a respective support providing support for the frame relative to the respective left or right hull when hulls are connected to the hull connections; the frame having a plurality of body attachments to facilitate attachment of the chassis module to a body of a vessel.

A ground effect craft having a ground effect wing, a plurality of sponsons, and a control system is disclosed. The ground effect wing may include a fore ground effect wing and an aft ground effect wing. The ground effect wing may generate a stabilizing moment on at least one sponson to stabilize the ground effect craft. The plurality of sponsons may be dynamically coupled to the body. The plurality of sponsons may be dynamically coupled to each other. The dynamic coupling may permit the sponsons to move relatively independent of the body and each other, thereby stabilizing the ground effect craft. The ground effect craft may include a stabilizing wing.
