Cost EffectiveAdvances in technology

allow utility-scale offshorewind to be cost-competitive

with a new fossil plant

New turbines, such as

the Siemens 6.0-154

shown here, produce

much more energy than

turbines made only afew years ago.

Deepwater contracted with Rhode Island Fast Ferry (Quonset, Rhode Island) to build

a state of the art crew transfer vessel

Rhode Island Fast Ferry contracted with Blount Boats (Warren, Rhode Island) to

build the vessel

The crew transfer vessel is a 70 catamaran with a tier 3 engine and custom bow to

safety and efficiently transport workers from the Quonset to the Block Island Wind

Wind energy will reduceemissions and energy prices

This effect, called pricesuppression has been welldocumented by NYSERDA for

wind farms upstate

Because Long Island has higheremissions and energy prices,offshore wind will have an evengreater benefit than wind farmsupstate
