(BELLINGHAM, Wash.) — Global classification society DNV has issued an approval in principle (AiP) for a 92-foot crew transfer vessel (CTV) concept design by All American Marine and Teknicraft.
The quad engine design concept has a beam of 33.5 feet with a projected speed of 29 knots, fully laden. This concept will incorporate HamiltonJet’s parallel hybrid EHX system using HTX waterjets, powered by quad MAN2862 LE 438 Tier 4 engines. The EHX system will allow for zero emissions when using battery power and will enable both station keeping and slow speed operations, as well as boost power when needed.
The vessel design concept is based on MO1, a proven vessel from Teknicraft that was built in 2013 to support the North Sea offshore wind market. The new concept design incorporates substantial updates and modifications, with the hybrid power system among its most noteworthy.
As an independent assessment of a concept within an agreed framework, an AiP confirms that the design is feasible, and no significant obstacles exist to prevent the concept from being realized. The AiP also establishes trust in the solution, as it is grounded on solid technical standards. For the emerging U.S. offshore wind market, establishing trust is essential.
“There has never been a more exciting time for offshore wind in the U.S., and the significant demand for vessels needed to support the market is part of what is driving that excitement,” said Antony DSouza, senior vice president and regional manager at DNV Maritime Americas.
The unique Teknicraft design incorporates a cutting-edge hull shape with an optional hydrofoil. When deployed in All American’s catamarans, this system creates lift and enhances the vessel’s performance.
Teknicraft hull designs have been recorded as producing one of the lowest levels of wake wash energy within their vessel class and can provide excellent fuel efficiency.
