TAI develops diesel electric hybrid Jones Act SOV design

New Orleans headquartered Technology Associates, Inc. (TAI), has added a diesel-electric hybrid offshore wind farm Service Operation Vessel (SOV) design to its EnviroMax vessel series.

The TAI EnviroMax vessels have been designed to maximize operational capabilities, minimize fuel consumption and carbon foot print. In addition to optimized operation, the designs offer unique features that reduce production costs.

The TAI EnviroMax SOV designs are being offered in the “S” (small), “M” (medium) and “L” (large) classes.

“Growth in the U.S. wind energy industry is inspiring,” says TAI President Anil Raj PE, “and our TAI EnviroMax series vessels are designed to be in sync with the environmentally sustainability objectives of U.S. wind power generation systems.”

EnviroMax SOVs are designed for Jones Act compliant U.S. flag operations and have twin azimuthing propulsion power, and a hybrid diesel electric plant. They are DP2, have retractable azimuthing bow thrusters, maximized mission spaces and more than 30 days of endurance.

The SOVs have speeds up to 15 knots and hold position in high sea states and currents.

The] vessels are optimized for reduced motions and accelerations in all degrees of freedom. High freeboards ensure dry working decks. They feature a telescopic, motion-compensated gangway that can extend and is designed to reach 27 meters above sea level to maximize operational days. They have a high degree of crew safety and comfort.

The 264-foot, “M” class SOVs has a 58-foot beam, which provides a large working deck of some 5,400 square feet with storage for up to 30 pallets. The 3,800-square foot, below-deck warehouse space can support 16 TEU containers or the equivalent in pallets. A 3-D offshore knuckle boom crane is installed for cargo lifting.

The “M” and “L” class vessels include a helicopter landing deck. The “M” class has accommodations for over 80 personnel, including a lounge, hospital, gym, training area and theater. Accommodations are in comfortable single person cabins for extended duration occupancy.

Four different EnviroMax size designs have been built in multi-ship contracts to support offshore oil & gas and seismic research. TAI’s designs for the U.S, Coast Guard’s Polar Security Cutter (WMSP) and NOAA’s AGOR Variant (NAV)have won U.S. Navy managed Detailed Design and Construction contracts for U.S. shipyards VT Halter Marine, Inc. and Thoma-Sea.
