Incat Crowther announced the delivery of a pair of Incat Crowther 35 Crew Transfer Vessels (CTVs) to MHO-Co. The two hybrid vessels, MHO Asgard and MHO Apollo, were constructed by AFAI Southern Shipyard and are the third and fourth Incat Crowther-designed vessels for MHO & Co.

MHO Asgard and MHO Apollo will service the Hornsea Project 2 offshore wind farm for Ørsted. The vessels follow on from MHO Esbjerg and MHO Gurli.

MHO Asgard and MHO Apollo are powered by a propulsion system that was developed in collaboration with Danfoss and Volvo Penta. The system comprises a pair of diesel drivetrains and a pair of diesel-electric drivetrains, each driving Volvo Penta Integrated Propulsion System (IPS) drives. The main diesel engines are Volvo Penta D13s, producing 515kW each.

The generators used for the diesel-electric propulsion train are Volvo Penta D8-MH units. A further three of these units are located in the hulls amidship, alongside a Volvo Penta D5 used as a harbour generator. Propulsion comes via Volvo IPS units. Additionally, a Corvus battery system provides stored power for zero-emission operation.


According to Incat Crowther, the vessel can operate in zero-emission electric mode for up to 8 hours, or in combination with diesel propulsion for a maximum speed of 25 knots. It also uses multiple modular generators which aims to optimise power generation for the operational profile.

Incat Crowther worked with MHO-Co to develop a design that improved on its predecessors, offering more space and functionality. The layout features a 110m2 foredeck with multiple tie-downs, deck crane, moon pool and the capability to take Bring-to-Work systems. The Z-Bridge BTW system has been tested on
MHO Esbjerg .

MHO Asgard and MHO Apollo accommodate 24 technicians in mid-deck cabins. A saloon for technicians is located on the main deck with 24 suspended seats, lockers, a pantry and a separate mess. Additional technician rest spaces are also located on this deck, as is a large wet room with lockers and showers.


“Designing and building hybrid CTVs is a huge step in the environmental direction, and I am proud that we at MHO-Co have found partners who share our vision for sustainable development in the offshore industry,”
said MHO-Co CEO and founder, Mik Henriksen.


Ed Dudson, Managing Director of Incat Crowther Europe said: “MHO Asgard and MHO Apollo demonstrate Incat Crowther's growing reputation for collaboration with operators and developers of new propulsion technologies, delivering fully-integrated solutions based on proven platforms.”
