Floating Offshore Wind Turbine Design Passes ABS Review

The American Bureau of Shipping (ABS) has completed the design review of the Front End Engineering and Design (FEED) documentation for the VolturnUS, a floating offshore wind turbine (FOWT), developed by the University of Maine Advanced Structures and Composites Center.   “UMaine is pleased that its innovative design became the first floating wind turbine concrete semisubmersible hull to be reviewed by ABS, and found to meet the ABS requirements,” said Dr. Habib J. Dagher, P.E, UMaine Composites Center executive director and principal investigator.    “After 10

US Awards $3.7 Mln for Wind Project off Maine

The Maine Aqua Ventus project, an experimental floating deep-water offshore wind project off the coast of Castine, Maine, has received $3.7 million from the U.S. Department of Energy.   The project was originally competing for a $47 million grant but was passed over for projects in New Jersey, Virginia and Oregon. The DOE instead awarded Maine $3.7 million for work to continue on a pilot project off the coast of Monhegan.

Maine Marine Earns Grant to Study Ocean Turbine Stress Limits

Maine Marine Composites has been awarded a $249,976 federal grant from the Bureau of Safety and Environmental Enforcement (BSEE) to analyze the best ways to predict fatigue in the support structures of floating offshore wind turbines. A federal agency, the BSEE was created in the wake of the Deepwater Horizon disaster in the Gulf of Mexico to promote safety, protect the environment and conserve resources in the exploration and development of the Outer Continental Shelf. "Maine Marine Composites engineers predict the performance and stress on components in ocean-based systems by analyzing

Universtiy of Maine's Advanced Structures & Composites Center granted up to $4 million to fund offshore windmill project. Habib Dagher, the director of the Advanced Structures and Composites Center, is busy planning the first phase of a “potential $93.2 million deepwater offshore wind demonstration project by the U.S. Department of Energy. The DOE held a competition to screen proposals for clean energy that would jumpstart wind farms in the United States. Seventy competitors submitted proposals for a chance to receive funding for their development of offshore wind energy. The UMaine

; The 155-foot-long, 60-foot-high and 60-foot-wide module was lifted to a height of approximately 100 feet using four cranes:  two of Bath Iron Works’ 300-ton capacity cranes and two additional 400-ton cranes provided by Reed & Reed, Inc., a construction company headquartered in Woolwich, Maine.  Once at the prescribed height, the ship’s 610-foot hull was then moved into position beneath the suspended module using the shipyard’s electro-hydraulic ship transfer system.  After confirming final positioning of the deckhouse and ship, the module was lowered into place.

amounts of a fine red seaweed clogging the coastline, the result of sweeping changes in the marine environment occurring beneath the water.   To further investigate, researchers at the University of New Hampshire looked at seaweed populations over the last 30 years in the Southwestern Gulf of Maine and found the once predominant and towering kelp seaweed beds are declining and more invasive, shrub-like species have taken their place, altering the look of the ocean floor and the base of the marine food chain.   In the study, recently published in the Journal of Ecology, researchers compared

Launching the Jamie Hanna

On August 14, 2012, more than 50 fellow lobsterman, boat workers, mechanics, family, and friends gathered to witness the launching of the 55-foot research and lobster vessel Jamie Hanna. A procession of cars made the 2 mile trip to the launching ramp at Outward Bound on Clarke Island, Maine. The lead car cleared the road to make way, as the 20 ton hydraulic trailer inched along and a crew on the pilothouse roof lifted phone lines and branches. When the boat arrived at the ramp an hour later, the tide was falling and concerns were raised about whether the boat would fit between the rocks and the

Delivery of Zumwalt Warships Delayed

 Problems with the complex technology being installed in the new destroyers of the Zumwalt class have forced the Navy and shipbuilder General Dynamics Bath Iron Works to delay delivery of the first two ships, the US Navy said.   Work at the contractor’s Bath Iron Works unit in Maine has fallen behind “due to the complexity of the first-ever all-electric ship and the particular demand it has created for skilled electricians shipyard-wide,” Commander Thurraya Kent, a Navy spokeswoman. The ships will be delivered a year later than planned.   The three ships are

Rebecca Stephens Smith, Marine Superintendent with DUNCOC, said "In its history the R/V Cape Hatteras spent a total of 5,401 days (14 years, 10 months) at sea collecting data and specimens along the Eastern Seaboard from Maine to the Caribbean. Beyond the public eye, research aboard the vessel has helped to expanded human knowledge and understanding of the ocean, the ocean floor, the water column, and the many living things calling the ocean home."
