The Damen Gorinchem Holland shipyard has ordered a hybrid-propulsion solution from MAN Energy Solutions in connection with the building of 2 × dual-fuel/hybrid RoRo ferries for Canadian outfit, Seaspan Ferries Corporation. The order covers the provision of MAN 35/44DF dual-fuel engines, fuel gas-supply systems and the main electric systems, including batteries.
MAN Energy Solutions will provide the solutions in association with Aspin Kemp & Associates (AKA), in which it has a 40% stake. AKA specialises in power supply, energy management and drive systems for marine and industrial applications.
Similarly, MAN Energy Solutions’ fuel-gas specialist, MAN Cryo, has been charged with supplying the new ferries’ fuel gas-supply system. MAN Cryo offers systems for the storage, distribution and handling of liquefied gases and was fully integrated into the company in 2015.
Wayne Jones OBE – Chief Sales Officer and Member of the Executive Board, MAN Energy Solutions – said: “We are very pleased to have won this order, and that our case was compelling enough for the customer to change an existing technical specification to our favour. It really showcases our strategic direction of developing sustainable technologies and solutions, and how we have expanded our business in recent years. This is a move that is now paying off as evidenced by the key roles that AKA and MAN Cryo play in this significant order.”
Jones concluded: “System technologies that help our customers to increase the efficiency of their plants and reduce emissions already form a significant part of our business, and also lead the way to a carbon-neutral future. The Seaspan order also fulfills our desire to increasingly become a supplier of complete solutions.”
Jason Aspin – CEO of Aspin Kemp & Associates – added: “This order represents a strategic milestone for AKA due to many factors. First off, it showcases the successful MAN and AKA partnership, offering highly innovative, full turn-key systems to operators. Secondly, it is a great opportunity for AKA’s technologies to be deployed in our backyard in Canada with a leading and forward-thinking owner like Seaspan. And lastly, with a technology where AKA has been a first mover in several initiatives for over a decade, this demonstrates that the marine industry is opening to the value that hybrid systems provide in meeting their environmental reduction targets while at the same time reducing their operating costs. We are very excited to see this project kick into full gear and look forward to participating in a successful outcome for all stakeholders!”.
Having initially been minded to build repeats from the existing LNG ferries, MAN Energy Solutions – courtesy of a live performance of its MAN 35/44DF engine – demonstrated that a fully-integrated MAN solution could better fulfill the owner’s requirements.
MAN Energy Solutions’ scope of supply for each shipset comprises:
- 2 × MAN 9L35/44DF Diesel/Gas-electric propulsion system
- 1 × MAN Cryo Fuel Gas Supply System including a 209m³ tank
- 1 × AKA main electrical system
- 1 × AKA 2-MWh energy storage systems
- 1 × AKA low voltage distribution system
The MAN hybrid-system solution in combination with a fully integrated MAN Cryo FGSS that is perfectly adjusted to the engines gas-flow requirements offers reliable operation in gas mode – especially in view of the ferry segment’s typical frequent and high load-fluctuations – and even with low methane numbers. For Seaspan, it was essential to avoid any diesel operation due to environmental and ecological reasons.
High system efficiency and the lowest emissions will also be achieved by having just one of two DF engines online at a time and at high load. Being able to operate with a one engine-online-concept facilitates significant savings in terms of vessels fuel costs, running hours and therefore spare parts/maintenance costs.
The propulsion and battery hybrid system, deeply integrated by AKA, provide sufficient propulsion power in all operational modes to serve Seaspan’s requirements to maintain its routes on time, fuel-efficiently, and with a minimal carbon footprint.
Additional AKA hybrid features for this project include peak shaving under rough conditions and maneuvering, enhanced dynamic support during ship acceleration, and zero-emissions operation at the terminal. MAN Energy Solutions will provide Seaspan a ready-for-the-future solution in view of the ecological and economical demands for its fleet-replacement programme and Seaspan´s future successful business.
The Maritime Energy Transition
The new Seaspan order is part of the ‘Maritime Energy Transition’, an umbrella term that covers all MAN Energy Solutions activities in regard to supporting a climate-neutral shipping industry.
The term stems from the German expression ‘Energiewende’ and encapsulates MAN Energy Solutions’ call to action to reduce emissions and, among other initiatives, establish natural gases as the fuels of choice in global shipping.
Launched in 2016 after COP 21, the initiative has since found broad support within the shipping industry and politics.
