Incat Crowther 35s Become the First Large Hybrid CTVs in Service

Press Release – Incat Crowther is pleased to announce the delivery of a pair of Incat Crowther 35 CTVs. Recently delivered by AFAI Southern Shipyard, MHO Asgard and MHO Apollo are the first hybrid CTVs in operation with extensive zero-emission capability. The vessels will service the Hornsea Project 2 offshore wind farm for Ørsted. The vessels are the third and fourth Incat Crowther-designed vessels for MHO & Co, following on from MHO Esbjerg and MHO Gurli.

MHO Asgard and MHO Apollo are powered by an advanced 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 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 3 of these units are located in the hulls amidship, alongside a Volvo Penta D5 used as a harbour generator. Propulsion is via highly efficient Volvo IPS units. Additionally, a Corvus battery system provides stored power for zero-emission operation.

The system offers exceptional flexibility, allowing the vessel to operate in zero-emission electric mode for up to 8 hours, or in combination with diesel propulsion for a maximum speed of 25 knots. The flexibility is enhanced by the use of multiple modular generators, meaning power generation can be optimized for the operational profile.

Incat Crowther worked with MHO-Co to develop a design that improved on its predecessors, offering even more space and functionality. The incredibly flexible layout features a vast 110m2 foredeck with multiple tie-downs, deck crane, moon pool and the capability to take B2W, Bring-to-Work systems. The Z-Bridge BTW system has been trialled on MHO Esbjerg.

MHO Asgard and MHO Apollo accommodate 24 technicians in mid-deck cabins. A comfortable 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,” says MHO-Co CEO and founder, Mik Henriksen.

Ed Dudson, Managing Director of Incat Crowther Europe says: “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.”
