The International Marine Contractors Association’s (IMCA) has published Standardised boat landing research report, with an aim to standardize boat landings for accessing wind turbine foundations from crew transfer vessels (CTVs). IMCA’s Renewable Energy Workgroup and the National Workboat Association (NWA) were seeking a consensus on the optimum design and configuration of boat landings for accessing wind turbine foundations from […]
German researchers gathered around the Research Alliance Wind Energy (FVWE) have completed a three-year Smart Blades project that resulted in new concepts for intelligent rotor blades which can adapt to the wind, thus allowing turbine rotor blades to produce electricity more efficiently, Fraunhofer IWES said in a statement. Rotor blades are subject to severely fluctuating wind loads due to the […]
A strong partnership has resulted in the development of a new wind turbine technology, which could mean a leap forward in blade control and cost reduction. Leading Danish wind industry players and the scientific community have joined forces to develop the iRotor technology, a solution which uses wireless sensor technology to measure changes in the […]
Transfers at sea have long been a problem and the safety of those involved is becoming an increasing consideration particularly because of the rapidly increasing numbers of people involved. The offshore wind farm owners and contractors alike have very strict H&S policies which other industries increasingly feel obliged to adopt as the renewable energy sector […]
A fracture in the welding that connects the tower top flange with the tower had caused the breaking of the turbine Number 7 at the Samsø (Paludans Flak) offshore wind farm, Siemens said in a statement. With the fracture developing over time, the tower top flange ultimately separated from the rest of the tower. “The welding at […]
DNV GL has certified a software developed by the Offshore Renewable Energy (ORE) Catapult as part of a project to develop a new bi-axial blade fatigue testing method. The project is aimed at reducing fatigue test times by almost a half and overall test times by a quarter. The two-year collaborative Knowledge Transfer Partnership project between […]
The DCNS Research teams have moved in their new facilities at Technocampus Ocean, located in Bouguenais, on the outskirts of Nantes, France. During the inauguration of Technocampus Ocean on 15 October, DCNS launched its rupture innovations workshop. The workshop aims particularly at fostering the emergence of new and inventive ideas and boosting their development in order […]
Ocean Power Technologies, Inc. (OPT) has deployed its APB350 A1 PowerBuoy approximately 14 miles northeast of Atlantic City, New Jersey. The APB350 A1 contains an improved Power Takeoff (PTO) system compared to the APB350 that was deployed in 2011 in connection with the U.S. Navy’s Littoral Expeditionary Autonomous PowerBuoy (“LEAP”) Program and then redeployed in 2013 […]
Grouting or bolting of the connection between monopile and transition piece belong to the past with the introduction of Dutch engineering company KCI’s Double Slip Joint. KCI is completely convinced about this after completing intensive research. The company introduced their new concept at the EWEA OFFSHORE event in Copenhagen last month where it attracted a […]
Recognising the critical role that substructures play on the Levellised Cost of Energy, a dedicated session was held on Tuesday 10th March at EWEA Offshore that discussed various foundation solutions. One of the session speakers was Dr. Azadeh Attari from engineering consultants, Gavin and Doherty Geosolutions (GDG), who presented preliminary results from the European Commission […]
The annual International Conference on Offshore Wind Substructures was held in Edinburgh last week, where the latest trends in foundation design and innovations in substructure technology were discussed.

Ocean Power Technologies, Inc. announced financial results for its Fiscal 2015 second quarter ended October 31, 2014 (“fiscal 2015”). David L. Keller, Interim Chief Executive of OPT stated, “I am pleased to report that during the second quarter we completed the site remediation and removal of equipment on the Reedsport, Oregon project which allowed us […]
The interest in structural health monitoring (SHM) in industry has increased significantly in recent years. Failure of a mechanical structure can indeed occur suddenly and provide a lot of damage. With SHM it is possible to follow up (online or offline) defects with permanently attached sensors. Damage to mechanical structures may consist of (small) changes […]
Tank testing of scale models to develop the next generation of Pelamis Wave Power’s wave energy converter (WEC) machines have now been successfully completed.
