Cummins Hotips#846      November 2018

from Ocean Choice.

Fish companies from New Zealand to Russia and Iceland to the USA as well as Greenland and now Canada have chosen the Norwegian firm Skipsteknisk when it comes time to design a new vessel. The firm has garnered a reputation for designing and overseeing the construction of vessels that integrate the most up to date technology from deck equipment to processing and stowage.

Ocean Choice International, of St. Johns, Newfoundland, Canada has ordered a new 74 by 16-meter freezer trawler to be built at the Tersan Shipyard in Turkey. For the design work, both hull and equipment, they went to Skipsteknisk. Given the vessel size and freezing capacity, electrical generation is an important consideration in the design.

In addition to a 6528-hp MAN main engine the designers designed in a Cummins QSK 60-powered generator with an output of 2155KVA/ 1724KWe, 3x440VAC, 3 phase, 60hz. An additional Cummins QSK19-powered generator has an output of 700 KVA / 560KWe, 3x440VAC, 3 phase, 60 Hz.

These will meet the extensive electrical needs of the vessel’s 39-crew accommodation block, extensive navigation suite, and processing factory. Most importantly the large freezer capacity will have a significant draw.

It is to partially meet electrical demands of the trawler that Ibercisa electric winches have been selected. These trawl winches have a remarkable quality, when the net is being payed out, the force of the turning winch generated electricity. It is similar to a hybrid car going down hill, but the new energy is not stored in a battery.

Inge Bertil Straume of Skipsteknisk explains, “By the use of active front end (AFE) technology, we are able to utilize regenerative power from the winches when paying out the trawl gear. Thus the winches work as a “power plant”.

“This free power will normally be utilized through the other major consumers on-board, like fish factory, freezing machinery and the hotel load. In the case of low demand on-board, this free power will be put on the propeller through the gearbox shaft alternator / motor ( in PTI mode).”

Of course the power from the winch is intermittent and small compared to the demands of the vessel. The electric winches make heavy demand when the gear is being retrieved. The two Cummins-powered, IMO 3 certified, generator sets will meet the vessel’s extensive electrical requirements.

Delivery of the, as yet unnamed, vessel is scheduled for the fourth quarter of 2019.
