New Orleans-headquartered Technology Associates Inc. (TAI) has added a diesel-electric hybrid offshore wind farm service vessel (SOV) design to its EnviroMax series of vessels.
TAI EnviroMax ships have been designed to maximize operational capabilities, minimize fuel consumption and minimize carbon footprint. In addition to optimized operation, the designs offer unique features that reduce production costs.
TAI EnviroMax SOV designs are offered in “S” (small), “M” (medium) and “L” (large) classes.
“The growth of the US wind industry is inspiring,” said TAI President Anil Raj PE, “and our TAI EnviroMax series vessels are designed to be aligned with the goals of environmental sustainability of production systems. wind power in the United States. “
EnviroMax SOVs are designed for U.S. flagged Jones Act operations and feature dual azimuth propulsion power and a hybrid diesel power plant. They are DP2, have azimuth retractable bow thrusters, maximized mission spaces, and over 30 days of endurance.
SOVs have speeds of up to 15 knots and maintain their position in high seas conditions and currents.
The vessels are optimized for reduced movement and acceleration in all degrees of freedom. High freeboards ensure dry working decks. They feature a motion-compensated telescopic gangway that can extend and is designed to reach 27 meters above sea level to maximize days of operation. They offer a high degree of safety and comfort for the crew.
The 264-foot “M” Class SOVs have a 58-foot beam, which provides a large work platform of approximately 5,400 square feet with storage space for up to 30 pallets. The 3,800 square foot warehouse space below deck can support 16 TEUs or the equivalent on pallets. A 3-D offshore knuckle boom crane is installed for lifting the cargo.
Class “M” and “L” ships include a helicopter landing deck. The “M” class can accommodate over 80 people, including a lounge, hospital, gymnasium, training area and theater. Accommodation is in comfortable cabins for a single person for long-term occupancy.
Four different sized EnviroMax designs were built in multi-vessel contracts to support offshore oil and gas and seismic research. TAI’s designs for the United States, Coast Guard’s Polar Security Cutter (WMSP) and NOAA’s AGOR Variant (NAV) have won detailed design and construction contracts managed by the US Navy for American shipyards VT Halter Marine Inc. and Thoma-Sea.
