Marine renewable energy has the potential to produce up to 20% of the UK’s current electricity demand, leading to extensive research and development activities in this area. As the industry of wave energy progresses toward commercialisation, a number of barriers still limit its potential, including the cost of energy. A significant portion of this is the cost of operation and maintenance…

Ocean Thermal Energy Conversion (OTEC) harnesses thermal energy stored at different seawater depths via power generation from a thermodynamic closed-loop cyclical system. Apart from its consistent energy generation, it could be diversified into other side industries, making OTEC an attractive and sustainable source of renewable energy. However, the process that utilises seawater as its main…

As the depths of sites consented for offshore wind increases, the need to develop floating foundations for wind turbines increases, as fixed foundations are only economically viable up to approximately 50 m water depth [2]. Key to developing the floating wind turbine industry is the development of accurate numerical models, which can combine the aerodynamic, hydrodynamic, structural…

Marine risers such as cables of cylindrical cross-section continuously encounter ocean currents during their service life, causing vortex-induced vibrations (VIV). Such oscillations can last a long period at high frequencies and produce significant damage that accumulates in structural components. The accumulated damage eventually leads to the failure of the structure.
The Reynolds…

Originating with the NSF-funded Living Bridge Project, a floating tidal energy conversion (TEC) system has been deployed at Memorial Bridge in Portsmouth, NH since 2018. The bridge crosses the Piscataqua River, in Great Bay Estuary, between downtown Portsmouth and Kittery, ME. The TEC system consists of a 15 m x 6m turbine deployment platform moored to one of the bridge piers and a modified…

The present paper presents the Reliability, Availability and Maintainability analysis performed by the authors in the framework of the H2020 REALTIDE project on two tidal turbine concepts - “complex bottom fixed tidal turbine” and “floating multirotor tidal turbine” (herewith called concept 1 and concept 3 respectively). The objective was to assess their designs and conditioning monitoring to…

The offshore wind industry is rapidly developing in a hurricane prone area off the US East Coast. For assessment of extreme environmental conditions, or hazard intensity measures, such as wind and wave loads (e.g., 50-year or 500-year wind speed) various methodologies including univariate (e.g., Generalized Extreme Value distribution; GEV) and multivariate (e.g., Inverse First…

The technology used in wave energy conversion systems is still in the early stages of research and development. There are a number of challenges associated with becoming a commercially viable source of renewable energy due to the high operating and maintenance (O&M) costs. A potential solution for increasing the availability of wave energy converters (WECs) and reducing operating and…

Many facilities in contact with seawater are constantly affected by marine biofouling.
In particular, marine biofouling cause many problems, such as reducing efficiency of water turbine, interfering with water barrier by stop log, and generating harmful gas (ammonia) due to the death of fouling organisms during Overhaul.
For this reason, Sihwa Tidal Power Plant has been researching… - Conference Paper:
Kim et al.
The turbine generator cooling water system of Sihwa Tidal Power Plant is an economical system in which the cooling water cools the turbine generator through a circulation pump and the rising temperature recirculates heat exchange with seawater through a surface cooler
However, as the cooling water facility continues to operate and a long period of time passes, the cooling water quality…

A vital aspect of ensuring the cost effectiveness of wave energy converters (WECs) is being able to monitor their performance remotely through structural health monitoring, as these devices are deployed in very harsh environments in terms of both accessibility and potential damage to the devices. The WECs are monitored through the use of measuring equipment, which is strategically placed on…

Marine energy sources are able to make significant contributions to future energy demands. Marine current has huge potential to supply renewable energy as compared to the other energy sources. Marine environment is harsh for the installation and operation of marine current turbine (MCT). Seabed scour around marine current turbine is induced when the flow suppression occurs at the seabed.…

Marine current energy is an abundant renewable energy resource. Marine current turbines (MCTs) can convert the kinetic energy of marine currents into electrical energy. However, the variations in the marine currents are violent and complex. These characteristics will be reflected in the variation in the operating condition of MCTs, thus interfering with normal diagnosis for the high-resistance…

The proposal of new technologies capable of producing electrical energy from renewable sources has driven research into seas and oceans. Research finds this field very promising in the future of renewable energies, especially in areas where there are specific climatic and morphological characteristics to exploit large amounts of energy from the sea. In general, this kind of energy is referred…

Tidal stream and wave energy resources may have the potential to complement the exploitation of wind power currently promoted, in industrial countries, as one of the alternatives to fossil fuel energies. However, despite a wide range of energy converters tested and deployed in real sea conditions, the exploitation of tidal and wave resources still shows high economic uncertainties associated…

Operation data in real conditions are generally essential to validate wave energy converter (hereinafter referred to as WEC) models and prototypes and to increase their operational safety, thus reducing costs. In this sense, the Mutriku Wave Power Plant, as one of the power plants with experience in generating energy from waves, makes its operation data from recent years available to…

Wave power in China has an energy density that is one-tenth of that of the wave power in Europe. Therefore, Chinese developers cannot simply replicate and transplant European devices and facilities to East Asia. Instead, to exploit the conditions in East Asia, a combined-oscillating-buoy-based wave energy convertor (WEC) is proposed as an array-type WEC. Sea trials of a 10 kW pilot device…
