DNV Awards Approval in Principle to All American Marine 92′ Crew Transfer Vessel Design

92′ Crew Transfer Vessel Design Principles

Global classification society DNV has issued an Approval in Principle (AiP) for All American Marine and Teknicraft Design’s 28 m (92’) Crew Transfer Vessel (CTV) concept design.

Engine and other specs

The quad engine design concept has a beam of 33.5’ with a projected speed of 29 knots, fully laden. This concept will incorporate Hamilton Jet’s parallel hybrid EHX system using Hamilton HTX waterjets, powered by quad MAN2862 LE 438 Tier 4 engines.

The EHX system will allow for zero-emissions operations when using battery power and will enable both station keeping and slow speed operations, as well as boost power when needed.

Concept Design of Crew Transfer Vessel

The vessel design concept is based on the MO1, a proven vessel from Teknicraft Design 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 the exclusive builder for Teknicraft Design in North America, AAM knows that this design concept will prove itself in the fast-expanding U.S. offshore wind market and set the stage for AAM to expand its leadership position into the manufacturing of CTVs and support vessels for the market.

AAM’s Naval Architect

All American Marine appreciates the unique needs of each customer and understands that no single design will fit every operator’s mission. AAM, with its naval architect, Teknicraft Design, focuses on the design and customization of each vessel before manufacturing, and throughout the build process to ensure that their customers’ be-spoke solutions achieve or exceed expectations.

Technical Standards

The pursuit of an AiP for this design with DNV demonstrates the AAM and Teknicraft Design’s commitment to excellence.  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, SVP and Regional Manager at DNV Maritime Americas.

“We are proud to partner with All American Marine and Teknicraft Design for the Approval in Principle of this CTV design. DNV sees collaboration as a key to the industry’s success and achieving the 30 by 30 target. It’s a pleasure to work with organizations like AAM and Teknicraft, who see the value of partnership and collaboration in the mission to achieve the industry’s common goals.”

AAM and Teknicraft Partnership

Two-plus decades of partnership between AAM and Teknicraft has resulted in a finely tuned process that benefits operators. Where the vessel designer and builder typically operate independently of one another, the exclusive relationship between AAM and Teknicraft applies a holistic approach.

The partners’ design and production teams consider every detail of a vessel’s mission before the build phase, to ensure the construction of the most fuel-efficient, lowest wake energy, and best performing vessel in its class.

Teknicraft’s Design Details

The unique Teknicraft design incorporates a cutting-edge hull shape with an optional hydrofoil. When deployed in our catamarans this system creates lift and enhances the vessel’s performance.

Distinctive design characteristics ensure high-speed travel, ultra-low wake, industry-leading fuel efficiency, superior seakeeping and is fully customizable depending on the application. With vessel applications ranging from law enforcement to research & Survey, to high-speed passenger ferries and cutting-edge eco-tour vessels, AAM has the proven expertise to build any Teknicraft Design in our state-of-the-art Bellingham, WA facility.

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, regularly exceeding
