MAN wins Seaspan ferry propulsion system order

Artist's impression of ferry
The two 149 m LNG battery hybrid RO/RO ferries recently ordered by Canada’s Seaspan Ferries (see earlier story) may look a lot like the pair delivered to the operator last year, but they are being built by a different shipbuilder and will have a different propulsion system supplier.
Damen Shipyards Gorinchem B.V. is to build the vessels at its Mangalia, Romania, yard and has placed an order with MAN covering the provision of MAN 35/44DF dual-fuel engines, fuel gas-supply systems and the main electric systems, including batteries.
MAN says that, though Seaspan had initially been minded to build repeats of the two previous ferries, 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 will provide the solutions in association with Aspin Kemp & Associates (AKA), in which it has a 40% stake. AKA specializes in power supply, energy management and drive systems for marine and industrial applications.
Similarly, MAN Energy Solutions’ fuel-gas specialist, MAN Cryo, will provide the new ferries’ fuel gas-supply system.
COMPELLING CASE
“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 favor,” said Wayne Jones OBE, Chief Sales Officer and Member of the Executive Board, MAN Energy Solutions. “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.”
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!”.
SCOPE OF SUPPLY
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 209 cu.m tank
  • 1 × AKA main electrical system
  • 1 × AKA 2-MWh energy storage systems
  • 1 × AKA low voltage distribution system .
SYSTEM CHARACTERISTICS
The MAN hybrid-system solution in combination with a fully integrated MAN Cryo FGSS that is exactly 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 means significant savings in fuel costs, running hours and therefore spare parts/maintenance costs.
The propulsion and battery hybrid system, integrated by AKA, provides sufficient propuslion 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.

NEW SEAWORK MARINE CONFERENCE TO FOCUS ON BILLION-DOLLAR MARKET



Unmanned Surface Vessels and Hybrid Propulsion will be the topics of a new European commercial marine conference taking place at Seawork on Wednesday 4 July.


Estimated at USD 470 million, the Unmanned Surface Vessels (USV) market is expected to reach around USD 1 billion by 2022 due to the ever-increasing need for maritime security, ocean mapping and data.
With Europe’s USV market set to grow at a higher rate than anywhere else globally, unmanned surface vessels are able to augment or even replace divers for salvage activities, port security, fish farms surveillance, bridge and dam monitoring and to aid research efforts.
The Seawork Commercial Marine Conference’s morning session will focus on USVs and will invite speakers from a range of industries, including Dr Katrina Kemp - Smart Ships & Automation Policy Officer at the Maritime and Coastguard Agency, who will be discussing the government’s emerging vision for autonomous, smart shipping; Ifor Bielecki – Director of Sea-Kit, on the challenges of long range, long endurance USV operations; and Gordon Meadow – Associate Professor at Warsash School of Maritime and Science and Engineering, who will be discussing their collaborative research project with Rolls Royce developing the unmanned and partially autonomous operation of marine vessels.
Marine hybrid propulsion systems are yet another fast-emerging market, estimated to reach around USD 5,252 million by 2024. Already a preferred, clean propulsion system choice globally, hybrid technologies are increasingly being used in several vessel categories. With the ever-increasing need to reduce operating costs and minimise fuel consumption, together with growing environmental and legislative pressures to bring down emissions, more and more vessel operators are beginning to see the benefits of embracing hybrid propulsion.
The afternoon session of the Seawork Commercial Marine Conference will centre around the future of hybrid propulsion and will invite speakers including Anne Duncan – CEO at Ecospeed, who will discuss how hybrid and windfarm operations could offer a clean solution for the shipping industry; Tony Birr – Consultant at Goodchild Marine Services Limited, on new developments in hybrid pilot boats; Dr Christoph Ballin- Co-Founder and CEO of Torqeedo GmbH, who will discuss the marine sustainability revolution and how hybrid propulsion technologies could play a key part.
Both sessions will provide businesses across the commercial marine industry the opportunity to keep ahead of the curve with developments within this fast-paced sector.

EUROPE: CATERPILLAR MARINE TECHNOLOGY ORDERED FOR HYBRID TUG


The Cat Marine Advanced Variable Drive is to be installed on a tugboat to be built by Turkey’s Sanmar Shipyard.
Announcing the contract, Caterpillar Marine said that its AVD will offer improvements in fuel efficiency and vessel performance by means of a fully-integrated hydro-mechanical propulsion system.
‘Different from a typical Power Take In (PTI) solution, the AVD incorporates a planetary gear set allowing seamless clutch engagement of main engines, auxiliary engines, or both to provide a scalable power installation to meet any customer need in terms of maximum vessel speed, power, or bollard pull,’ explained Nathan Kelly, product definition engineer for Caterpillar Marine. 
‘This also allows propeller speed independent of engine speed so optimal engine efficiency can be achieved leading to fuel savings of 15%-20%.’
The Sanmar hydraulic hybrid tug will be a Robert Allan Ltd-designed RAmparts 2400SX harbor tug incorporating an integrated Caterpillar AVD system of 3512 main engines, a C32 auxiliary engine, Cat MTA 627 fixed pitch tug thrusters, and bridge controls.  
Compared to a conventional tug with equivalent bollard pull, the return on investment is estimated at three years or less, based on projected fuel and operating cost savings.
Ali Gurun, director of projects, Sanmar Shipyards, commented on the new vessel initiative: ‘This strategic development between Sanmar and Caterpillar will provide a highly optimised, lower cost alternative to conventional electric hybrid systems with similar benefits regarding improved performance, lower noise and lower emissions.’
