Discover the new generation of WAVECRAFT ™ Crew Transfer Vessels

The WAVECRAFT ™ series of crew transfer vessels is based on 30 years of proven technology and solid expertise in delivering most sophisticated composite high-speed vessels to the most demanding defense and commercial markets worldwide.

We have reached and crossed new technological frontiers and now offer new generation of high-performance WAVECRAFT ™ Crew Transfer Vessels for the Renewables, Oil & Gas, Passenger and Defense sectors.

All WAVECRAFT ™ vessels are based on proven Surface Effect Ship and air-cushion catamaran design, which guarantees rapid transit time, excellent seakeeping and passenger comfort, superior fuel economy and reduced environmental footprint.

Structural design of our vessels presents low wake wash characteristics, enabling safer, high-speed operation in shallow and confined areas, while benefiting atmospheric and marine environments.

WAVECRAFT ™ crew transfer vessels are equipped with sophisticated motion control system, which compensates for vertical wave motion, offering comfortable transit and safe access to other vessels and installations offshore.

We build all our high-performance navy and commercial vessels in composite sandwich materials, where low structural weight presents several benefits, including: high speed, high payload fraction, reduced displacement, lower power requirements, and up to 20-30% lowered fuel consumption than aluminum vessels, resulting in lower emissions.

Umoe Mandal is supported by the Norwegian state-owned Export Credit Norway, which provides competitive long-term loan financing solutions to national and foreign companies looking to purchase goods and services from Norwegian exporters.
