Surface Effect Ship Designed for Crew Transfer Vessels
ESNA and Strategic Marine have signed an agreement to develop a SES CTV (Surface Effect Ship Crew Transfer Vessel) for offshore wind applications.According to Wikipedia, a surface effect ship or sidewall hovercraft is a watercraft that has both an air cushion, like a hovercraft, and twin hulls, like a catamaran.The vessel type offers the combination of higher speed, increased operational wave height and reduced fuel oil consumption.The plan is to start building the first offshore…
U.S. Offshore Wind: GLDD Orders Huisman Rock Installation Equipment for Newbuild Vessel
U.S.-based Great Lakes Dredge & Dock Company (GLDD) has ordered rock installation equipment from the Dutch company Huisman.The equipment will be installed on the GLDD's newbuild rock installation vessel, which will support the development of offshore wind in the U.S.Huisman said it has optimized the equipment for installing scour protection necessary for offshore wind applications. This includes, for example, filter and armor layers for foundations, which it can install pre- or post foundation installation. It can also install cable protection for both inter-array and export cables.
DNV GL Guidelines for Floating Wind Power
DNV GL, the world’s largest resource of independent energy experts and certification body, has published the revised standard for design of floating wind turbine structures DNV GL-ST-0119, and a new guideline for the certification of floating wind turbines, DNVGL-SE-0422.Together, the two documents define design and certification requirements for floating offshore wind turbine concepts, prototypes and projects. The guidelines provide the most comprehensive technical reference suite for this emerging technology, enabling the safe and reliable realisation of floating wind projects.The documents cover the complete requirements for the integrated system and can be applied for design and certification of floating wind farms…
DNV GL Signs Certification Deal With Blade Maker Sinoma
DNV GL and the wind turbine blade manufacturer Sinoma signed a partnership agreement for certification of Sinoma’s products to improve the reliability and quality of blades manufactured in China. Certification ensures that turbines that use blades produced by Sinoma comply to international safety and reliability standards throughout their lifespan, in onshore and offshore wind applications. As wind turbines increase in size, the failure of key components as rotor blades can lead to significant losses for the different stakeholders involved. “Turbine manufacturers constantly work on improving quality and reliability of wind turbine components such as rotor blades and gearboxes for example,” explains Daniel Hein, Country Manager China for Renewables Certification, DNV GL.
Saint-Gobain Announces Renewable Energy Initiatives
An early glimpse into the 2013 Annual Energy Outlook from the U.S. Energy Information Administration reveals that increased generation from renewable energy is expected to account for 32% of the overall domestic growth in electricity generation from 2011 to 2040. With this insight and reports of global growth forecasts in renewable energy from both financial and market analysts in mind, Saint-Gobain Performance Plastics today announced its initiatives for composite bearings applications in renewable energy markets.
