Schiffstechnik | Ship Schiffstechnik | Ship Technology A colorful hybrid The charge is building up: The progress of the »Color Hybrid« ship construction in spring 2019 has been steady, and the plug-in hybrid vessel is getting prepared to enter service in June with a lot of innovative technology on board For a long time, Ulstein Verft’s yard number 311, the »Color Hybrid«, has been hiding in the dock hall. Now it has been painted and launched. The delivery is scheduled for May 2019 to enter service in June, so the waiting for the world’s largest plug-in hybrid vessel will be over soon. The environmentally sound ship will be servicing the 38nm route between Sandefjord – Strømstad (crossing time 2,5 hours) from summer 2019 . Ulstein won the contract in competition with several other yards. In Februabry 2017, Color Line and Ulstein Verft signed the contract on construction of the 30,000 GT ship designed by Fosen Yard. The new RoPax cruiseferry uses new solutions to reduce noise and emissions. The vessel features a diesel-electric plugin hybrid concept with PTO/PTI allowing for hybrid propulsion using both direct-drive and electric. Siemens batteries installed in four battery rooms in the machinery area deliver a combined capacity of 4.7 MWh. At vessel speeds up to 12 kn, the 5 MWh battery package weighing almost 70 t is going to allow for 60 minutes of fully electric operation. In normal operation the vessel’s top speed is 17 kn. The battery system was delivered by Siemens, who manufactured the batteries at its new production facility in Trondheim. Siemens is well-known for being a key supplier for ferry operator Scandlines’ hybrid ferry »Berlin« (196 m, 1,600 lane meters), which is in service in the Baltic since 2016 and uses batteries with a combined capacity of 4.5 MWh. The energy management system for this vessel and her sister ship »Copenhagen« already came from Siemens, while the batteries came from Corvus Energy. The batteries are recharged via a power cable with »green« electricity from shore facilities or, as a secondary alternative, recharged on board by the ship’s generators. With shore power provided in Sandefjord, all Norwegian ports on Color Line’s network will have shore power facilities. The ship will have full battery power into and out of the fjord to Sandefjord inner harbour. It will therefore not give emissions of harmful greenhouse gases or nitrogen and sulphur compounds in this area. The ship is equipped with four Rolls- Royce Bergen B33:45L in-line diesel engines of which two are B:33:45L6 (six cylinders, 3,600 kW) and two are B33:45L8 (eight cylinders, 4,800 kW). The four engines were delivered in March 2018, the contract came with an option to provide engines for a second vessel. The »Color Hybrid’s« engine and energy layout also features a waste-heat recovery system. Norwegian company Brunvoll supplied the propulsion package including controllable pitch propellers and tunnel thrusters, gearboxes, rudders and steering gear. Besides the two CP-propellers, Brunvoll delivered two fixed-pitch propeller tunnel thrusters and one rim-driven, permanent magnet tunnel thruster as well as control systems for propulsion, positioning and manoeuvring. A »local« project Steel cutting started in July 2017, in April 2018 Crist shipyard in Gdynia, Poland, began to assemble the 14 blocks of the ship’s hull. After the hull was completed it was then towed to Ulsteinvik in November 2018 for outfitting. According to Ulstein, »Color Hybrid« is a good example of the interaction in the © Color Line 14 HANSA International Maritime Journal 05 | 2019 NorShipping
