European initiative to develop a wind-wave power open-sea platform equipped for hydrogen generation with support for multiple users of energy. The three-year project, called H2OCEAN, aimed to develop an innovative design for an economically and environmentally sustainable multi-use open-sea platform. The consortium comprised 17 partners from five European countries (UK, Spain, Denmark, Germany and Italy). The project was fnded by European Commission’s Seventh Framework Programme (FP7) provided three-quarters (€4.5 million) of the total €6 million funding.

The TROPOS Project was aiming to develop a floating modular multi-use platform system for use in deep waters, with an initial geographic focus on the Mediterranean, Tropical and Sub-Tropical regions, but designed to be flexible enough so as to not be limited in geographic scope.
TROPOS has 20 partners from 9 countries (Spain, the United Kingdom, Germany, Portugal, France, Norway, Denmark, Greece and Taiwan), under the coordination of PLOCAN

MERMAID looked at developing concepts for the next generation of offshore platforms to be used for multiple purposes, including energy extraction, aquaculture and platform related transport. The project did not build new platforms, but theoretically examined new concepts, such as combining structures and building new structures on representative sites under different conditions.

The MERMAID project had 28 partners including Universities, Research institutes, Large, Small and Medium Enterprises. The group represented a broad range of expertise in hydraulics, wind engineering, aquaculture, renewable energy, marine environment, project management as well as socio-economics.

The Multi-Use in European Seas (MUSES) project is a Horizon 2020 funded project that is exploring the opportunities for Multi-Use in European Seas across five EU sea basins (Baltic Sea, North Sea, Mediterranean Sea, Black Sea and Eastern Atlantic). MUSES builds on existing knowledge to explore the real opportunities for Multi-Use in European Seas, including the scope for innovation and Blue Growth potential and to present practical solutions on how to overcome existing barriers and minimize risks associated with Multi-Use development. MUSES was a two year project, co-ordinated by Marine Scotland, that concluded in October 2018. There were 10 project partners from across Europe.

Comprised of concrete floatation chambers joined together by flexible links using a modular adaptive architecture, MPOP will be large infrastructures that can withstand large swell conditions. Modularity will make the tasks of movement, assembly and maintenance much easier.  This project is at early stage – R&D awaiting public support .

Marine Investment for the Blue Economy (MARIBE) is a Horizon 2020 project exploring cooperation opportunities for companies that combine different Blue Growth and Blue Economy sectors.  The project is identifying opportunities to unlock the potential of multi-use of space and multi-use platforms. The project is 18 months and has a consortium of 11 partners from Ireland, United Kingdom, Belgium, Spain, Italy, Malta and the Netherlands. The project is coordinated by University College Cork (MaREI)

Swedish company Hexicon and engineering partner Atkins are working together on a commercial demonstration project; the Dounreay Tri offshore wind floating platform which is due to be located off the north coast of Scotland. The platform will have a two turbine 5 MW structures mounted on it.  The partners have been working together since 2015 and the construction started in March 2017. The project is currently on hold, but there is strong commitment of the project’s key suppliers to re-start the project and commissioning is planned latest Q1 2020.

This is Norway's first development concession enabling Ocean Farming AS, supported by Kongsberg Maritime AS, to build the world's first automated 'exposed' aquaculture facility.It is situated outside of Trondheim. The Ocean Farming facility is a new and innovative design, developed to overcome the challenges of more traditional inshore fish farming facilities by being located in deeper waters, further from the coast. The submerged, anchored fixed structure will float steady in the exposed ocean and is suitable for water depths of 100 to 300 meters, where the aqua biological conditions are more ideal for aquaculture on 'the fish's terms'.

Havfarm  is an aquaculture vessel being built in China which will be the largest ‘ship’ in the World when completed in 2020. It is 431 metres in length with a beam of 54 metres.  The vessel will be anchored in waters off the coast of Norway with a turret mooring system similar to those used in the offshore oil industry.

SalMar is a Norwegian Fish Farm Platform. The consortium is planning to build another huge offshore platform possibly twice the size of Ocean Farm 1, which was brought in from China last summer.

SalMar and MariCulture have signed a partnership to develop a new offshore aquaculture concept called Smart Fish Farm that can operate in the open sea.  The concept is quite different from anything so far conceived in that this huge new platform should be able to withstand wave heights of up to 15 metres.

Keppel Offshore Marine

Offshore rigs for fish farms are being developed by Keppel Offshore. The prototype consists of a semi-submersible — a raised platform above sea level connected to a floating ring pontoon by columns — attached to six hexagonal fish cages.  The cages, which are submerged underwater to minimise sea surface obstruction, can be controlled remotely and raised above sea level to harvest fish or for maintenance or repair.  The platform above water can house hatcheries to supply healthy fish fry, as well as an operations centre to manage a gamut of activities from feeding, cage cleaning and inspection, to tracking the health, diet and growth of the fish.  There could also be a processing plant to fillet, package and chill the fish.

The P37 is described as 'the only wave wind device in the world that has produced joint power to the frig in the real offshore environment.'

Over a period of several years P37 has been tested, to document the efficiency rate in off-shore conditions and the use of the system as a floating foundation for wind turbines.

This multi-purpose floating platform integrates wind, solar, wave and tidal energy devices in limited water space. Combining multiple renewable energy devices in such a manner could potentially offer stable electricity production 24/7, despite seasonal changes. The company’s proven RPC technology allows the platform to start small and scale up in very short periods of time. Its modular design enables remote production, assembly in situ and direct installation on water, saving significant amounts of time and money for the client.

The Marine Energy Utilization Research Division of Nagasaki University focuses on the research and development of marine energy utilization. Engineering research focuses on the application of mechatronics to provide robotic assistance and IoT (Internet of Things - providing system interconnectivity, data sharing etc.) to support a fully integrated and largely autonomous marine energy network.

They are conducting leading edge research in developing advanced robot mechatronics systems. For example the development of marine strength rope, smart underwater cables, underwater charging, optimized control for floating wind power clusters and intelligent breading systems.

National Ports’ modular port solutions provide a cost-effective and practical floating port for all types of cargo.

Smart Floating Farms by Forward Thinking Architecture

Concept published in 2015.   Initial Unit measures 60m x 35m (replicable and scalable) and will be anchored to land (calm waters, marinas, lakes rivers). Designed for Autonomous Triple-decker Farm Barge.  Solar panels on top deck providing power for the middle deck hydroponic food production and the Commercial recirculating aquaculture system below.


The resulting platform will integrate proven commercial systems such as mooring systems, pontoons & floating structures, hydroponics (cultivation and irrigation high yields with reduced costs and less water use), RAS aquaculture / tanks and middle size commercial desalination unit (for salt water areas).

Offshore Power Plant (OPP) for use of the coast of Japan.  The concept was announced in 2006. In 2015 the company was working with Siemens to develop the OPP.

SeaFloat is developing concepts for floating combined cycle power plants.  It is anticipated the first could go into operation in 2020.

The basic idea is that power plants should be built on ships or floating platforms instead of being erected on land.

Float In in the USA have produced a concept floating multi-use platform designed to serve as a shipping container terminal located off the south of Ireland (Portunus Project).  Pneumatically Stabilised Platform (PSP) permits the construction of stable, floating reinforced concrete foundations of unlimited size for use on any body of water deep enough to float them.  Rho-Cee Wave Energy Converter to generate power.  Potential Energy  Storage (PES) stores captured energy as compressed air.  LNG Terminal provides baseload electricity, potable water.

This EU Project is demonstrating and benchmarking a floating wind turbine system for power generation in Atlantic deep waters. This project follows 3 main objectives:

  • Proving the technical, economic and environmental feasibility of an EU technology floating system in deep waters;

  • Bringing wind energy applications closer to market in diverse European deep offshore areas;

  • Assessing the expected global generation cost per MWh in a 15-year perspective.

The Offshore Wind Turbine became fully operational in September 2018.  A second unit is soon to be operational off Japan. To view the video click here.

WindFloat® is a floating foundation for offshore wind turbines with a simple, economic and patented design. The innovative features of the WindFloat dampen wave and turbine induced motion, enabling wind turbines to be sited in previously inaccessible locations where water depth exceeds 40m and wind resources are superior. Prototype is a 2 MW wind device but the next generation WindFloat will be optimised for 5 - 8MW and the future 8+ MW offshore wind turbines.

This platform is IDEOL’s second demonstrator and is installed at Kitakuyshu, Japan.  It carries a 3MW offshore wind turbine and is anchored in a water depth of 55 meters. It was commissioned in 2018.

The objective of the project is to validate a floating technology with a view to equipping future commercial floating farms that the Japanese want to see installed by 2030.
