Rolls-Royce to Deliver Automatic Crossing System to Fjord1 Rolls-Royce will supply an automatic crossing system to Norwegian ferry company Fjord1. The system, the first to be supplied by Rolls-Royce, will control two new double-ended battery ferries as they cross between Anda and Lote on the 1,330 km long E39 route connecting communities along the west coast of Norway. Construction on the two new ferries is to start this fall at the Tersan shipyard in Turkey, with delivery in 2017. As part of its agreement with the Norwegian government, Fjord1 must keep strict yearly limits on its battery-powered ferries. To that end, the automatic crossing system will help Fjord1 ensure consistent behavior during a vessel’s journey and help with energy consumption. The system will automatically control the vessel’s acceleration, deceleration, speed and track. Two energy efficient RollsRoyce Azipull thrusters respond adaptively to environmental conditions.
The system, developed by Rolls-Royce’s Ship Intelligence Program, “will help the customer meet their contractual need to ensure predictable energy consumption optimized for varying environmental conditions,” says Jann Peter Strand, Rolls-Royce, Product Manager, Automatic & Control — Marine. “It is a step on the road to realizing Rolls-Royce’s goal of remote and autonomous vessels.” The system will work in conjunction with a Captain who will maneuver the ferry manually a few meters from the dock. The Captain will then supervise the system and intervene should it be needed—and should the Captain be unable to take manual control, the system will stop at a safe distance from the quayside and stay positioned until further action can be taken. Rolls-Royce says that the next version of the system will allow for automatic berthing.
Damen Green Solutions has signed a letter of intent with Norwaybased TeamTec AS to supply the innovative Avitalis ballast water treatment system (BWTS). Under the agreement Damen will deliver the global sales, integration engineering installation and servicing capability for the system via its 32 yards around the world. The system, which is currently undergoing land-based testing for U.S. Coast Guard approval and shipboard testing for IMO approval, uses a combination of filtration and chemical treatment. The chemical used in the treatment process is Peraclean Ocean, developed by Germany’s Evonik Industries AB. The chemical has a broad anti-microbial spectrum making it effective even at low temperatures and rapidly decomposes into water, oxygen and acetic acid. The system works in a two-stage treatment process. The ballast water is first pumped through a 40 µ automatic self-cleaning filter, where more than 90% of the organisms ≥ 50 µ are filtered out and pumped back into the water. Peraclean Ocean is then injected into the ballast water and disinfection happens immediately. Avitalis is highly effective in water of any salinity, turbidity or temperature. It is anticipated that IMO type approval will be achieved in the first half of 2017, followed by full U.S. Coast Guard BWMS type approval later in the year.
