Multi-Purpose Floating Structures are special design in water floating structures applications, long lasting and easy for replacement. It is the most economical and safe way to build a floating structure to suit for anything that are floated on the water. The mounting frames are designed with capability of ensuring system integration, components replication, cost reduction and modularization by using recycled plastic drums or other floating containers.

A deep-sea multi-energy integrated platform for complementary power generation, production, living and exploration includes a platform body and a sustainable power supply system, where the platform body includes a column cabin, an upper platform housing, a lower platform housing and a current guide column; the column cabin, the current guide column, the lower platform housing and the upper platform housing are mutually connected to form a triangular platform with a hollow cavity, and a net is disposed in the hollow cavity to form a mariculture zone; the sustainable power supply system includes a wind-driven generator disposed at an end of a top surface of the upper platform housing, a solar panel disposed above a middle portion of the top surface of the upper platform housing, a wave power generation apparatus disposed on the current guide column, and several tidal current power generation apparatuses.

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 riser system with a primary conduit extends between a surface vessel and a subsea location and an auxiliary conduit that extends adjacent the primary conduit. In one example a composite jumper conduit extends from the surface vessel and is fluidly connected to the auxiliary conduit. The jumper conduit includes a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix. In one example a subsea composite jumper conduit extends from subsea infrastructure and is fluidly connected to the auxiliary conduit. The subsea jumper conduit includes a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix.

A supporting system for a floating unit in shallow water exerts controlled stresses on the floating unit hull and includes supporting structure for the hull. An extendable supporting device operatively connects to the supporting structure and is suitable to support a predetermined weight of the floating unit and load when entirely supported by the extendable supporting device and when the extendable supporting device rests on a bed of a water body. An actuator device connects to the supporting structure and operatively connects to the extendable supporting device for extension or contraction. A control device operatively connects to the actuator device to control the extraction or contraction movement of the extendable supporting device. The system includes at least one hull stress monitoring device operatively connected to the control device. A device to monitor the stress, or load, on the extendable supporting device operatively connects to the control device.

A subsea fluids storage facility comprises a tank for holding and separating fluids which is equipped with ballast capacity and a separable base to be deployed upon the seabed in shallow or deep water, and the storage facility is connectable to a surface production facility, especially a buoy for processing fluids. In deep water the tank is held at a depth above the base for temperature controlled stabilization of produced oil in the tank.
