PLATFORM PROVIDED WITH RENEWABLE ENERGY CONVERTER SYSTEMS
Patent Number: GB 2383978
A platform is designed as a floating structure to intercept and convert renewable marine and other energy sources, notably solar energy, energy of winds, waves and sea currents, geothermal and ocean thermal energy conversion, (OTEC), any combination of such available sources optimised to generate electricity to power on-board facilities, to be cabled to nearby land grids, or transformed by hydrolysis into oxygen, and hydrogen, a clean fuel for the future which can be pipelined or tankered to land, thus relieved from the negative effects of land-based power plants. The platform or linked platforms are an extension of land and can be used additionally for controlled environment agriculture but also for housing and industry and the waters below for mari-culture. When linked in a linear mode, energy platforms can provide coastal protection. The vast pollution free energy resources available from such platforms can provide a significant proportion of world energy requirements.
MARINE PLATFORM TETRAHEDRAL STRUCTURES
Patent Number: GB 0725365.1
Marine platforms are used in many applications, in particular relating to oil and gas exploitation.
It is proposed that platforms are built to consist of a deck, supported by a tetrahedral triangulated structure, which provides great strength and offers very little resistance to oncoming waves, taking the deck loads down below the areas most affected by the waves, to profiled buoyancy vessels whose air content can be varied to lower or raise the platform according to wave heights, including those of rogue waves, guaranteeing the safety of people and equipment on the deck in all weather conditions, the platforms, near shore or on shore having many other applications.
APPARATUS FOR DERIVING POWER FROM SEA WAVES AND SOLAR ENERGY
Patent Number: GB 0901780.7
There are many devices proposed to capture energy from sea waves, some land based, others limited to shallow waters and some designed for the open seas. They share in common their reliance on solid structures.
It is proposed to capture wave energy with flexible membranes, an upper membrane following the waves’ movements, and a submerged membrane weighted and valved, in waters less affected by the waves, the two linked by extensible hose pumps or ties with hydraulic actuators, the hydraulic pressure used to generate electricity or provide desalinated water by reverse osmosis.
The flexible nature of the device is compatible with marine conditions, and presents less danger to navigation than solid floating structures, with no visual interference, the device, also useable as a wave attenuator, needing to be clearly signalled. The large surface of the upper membrane is used to carry solar energy converters, photovoltaic, photo-thermal or photo-biological.
Patent Nunmber: 1100823.2
Land next to the sea is generally built-up and development land there is often too expensive or unavailable.
It is the purpose of the following invention to create development platforms at sea, one being made up by bringing together six ships designed to form a hexagon, the prow of one ship designed to be firmly fixed to the rear of the neighbouring ship, one of the ships provided with an opening such that boats can enter a central harbour, the centre formed by inner platforms providing accessible deck space. Each ship is composed of a hull which provides the flotation and large rooms, and a superstructure where apartments, hotels, ground floor shops and public spaces are planned.
Since the life of conventional hulls is around 50 years, a system is provided by which the superstructures can be slid from an old or damaged hull to a new hull brought alongside.
LOW LEVEL PUMPED OTEC COLD WATER PIPE
Patent Nunmber: 0803919.0
Thermal Energy Conversion (OTEC) applications, is made of rigid materials, generally metal or concrete, This is necessary because the circulating pumps are located on the platform vessel or land site from which they originate.
It is the purpose of the present invention to locate the pumps at the low level base of the pipe, so that the pipe contains water pressurised from the base, giving form to the cold water pipe. or CWP, allowing for the use of a greater diversity of materials, from rigid structures needing thinner walls, to semi flexible or flexible materials, stabilised by the inner water pressure, such CWPs able to be used conventionally as horizontal plungers, or able to follow uneven surfaces of coastal falls, and having many other applications, allowing considerable savings in costs, and, because of their flexibility, less prone to fracture than rigid CWPs.
OTEC LOW LEVEL CONDENSER
Patent Nunmber: 2395754
An Ocean Thermal Energy Conversion system is provided with a condenser, located in deep cold waters, to which the vaporised working fluid vapour, having driven a surface-mounted turbo-generator, is transferred down a conduit, the condenser being formed of heat exchangers taking the cooled vapour back to its liquid state. It runs into a sump from which it is pumped up by a single pump, or a series of pumps linked to break tanks, through an insulated tube back to the surface, where heat exchangers expose it to surface water heat. This causes the condensed working fluid to vaporise, driving the turbo-generator, the vapour being returned again to the condenser, to complete the cycle. The condenser is located at the lower end of a tube, containing linking pipe work and machinery, which may serve as access, and as guide to raise the condenser to the surface for maintenance. of the accompanying drawings.
Patent Nunmber: 2396335
Oil tankers and ships carrying dangerous cargo are frequently prey to accidents that cause them to break up and sink, spilling their contents that cause environmental calamities.
A cover in the form of a generally elliptical dome can be lowered over the wreck to prevent its spill from propagating. Since speed is essential, it is proposed to use inflatable structure techniques to fabricate the dome from membranes and pressure rigidised tubes, the whole assembly being initially compactly folded on a specialist ship, and deployed and lowered over the wreck whose emissions are contained, a valve being provided at the crown to allow oil and lighter than water fluids or gases to be pumped away to surface recovery vessels. The rapid intervention of such measures could limit or totally prevent environmental disasters by tackling these “ at source.
