MHO-Co Hybrid Vessel
MHO-Co’s two new crew transfer vessels (CTVs) – MHO Asgard and MHO Apollo – have been put through their paces, having traveled from China to Denmark. The 12,000 nautical mile journey was a voyage of discovery for Volvo Penta and Danfoss Editron, with the many lessons learned helping to create a tailor-made solution fit for the owner’s requirements.
Danfoss Editron and Volvo Penta treated the journey from China to Denmark as a pilot project and a time to work with the captains and crew to tweak the novel technology onboard and make it as reliable and efficient as possible for the customer. The companies were able to test different power combinations, such as diesel-electric operation or diesel-only. In Dynamic Postitioning System-mode (DPS-mode) fuel consumption is below 20 liters/hr. and can be as low as 17 liters/hr. which is exceptional for vessels of this size class.
All these tests were carried out with the captain and stakeholders, which meant the result was a solution that was fit for purpose for the operator’s requirements. From these initial learnings, the teams have started adapting the drivetrain – not just the motors themselves – to all-electric propulsion needs.
Volvo Penta also worked with captains during the design phase to reimagine existing systems. For example, to take the electric propulsion dimension into account, Volvo Penta created a completely new HMI. To do this, the company worked closely with the captains during the design phase. Volvo Penta took advantage of options offered by the power of plenty, different kind of captain controls, and reading diagnostics differently to develop the HMI.
“The design, build, and delivery of these vessels was all about teamwork and collaboration,” explains Erno Tenhunen, Danfoss Editron’s Marine Director. “Ultimately, these are learning projects on all sides. We are trying to push the limits of technology, and the best way to do this is to bring our unique ideas, perspective, and knowledge together. That’s exactly what we have done here.”
