MAN Propulsion for 7 Russian Factory Trawlers
MAN Energy Solutions said it has won the contract to supply propulsion systems for seven new 109-meter factory trawlers for the Russian Fishery Company (RFC).
The series’ lead vessel will be built by Tersan shipyard in Yalova, Turkey for scheduled delivery in July 2020. The following six identical vessels will be constructed in Russia.
The configuration of the newbuilding’s propulsion system features a MAN 14V32/44CR main engine (delivering 8,120 kW), a MAN Alpha VBS 1260 propeller, a gearbox including power take-off/power take-home with startup converter, and 1× MAN 9L21/31 + 1 × MAN 7L21/31 GenSets. System delivery for the first vessel is scheduled for June 2019.
The propulsion system features advanced common-rail technology to achieve high degrees of flexibility and efficiency with the main-engine power of 8,120kW. This doesn’t compromise the low fuel-oil consumption and maintains a green footprint.
The vessels will operate using IFO (380 cSt) fuel for both main propulsion and auxiliary power generation, equipped with a four-bladed, 4.3-meter-diameter MAN Alpha VBS1260 propeller with Alpha High Thrust propeller nozzle class ICE 1A Super.
Each vessel will feature an Alphatronic 3000 propulsion-control system with unique features such as customized multiple combinator curves for both speed 1 and speed 2 including floating frequency. Also included is an 850 kW PTI reverse-power mode for winch energy recovery that via PMS interfaces with the SaCoS engine system and Alphatronic 3000 system.
The complete package supply is specified to include MAN PrimeServ online service and crew training.
The high-tech factory trawlers were designed by Norwegian naval architect Skipsteknisk to have catching and processing capacity for more than 400 metric tons of pollock or 350 metric tons of herring per day, with a 300-metric-ton-per-day freezing capacity, plus a 250 metric-ton-per-day meal and oil plant. Fishroom capacity is 4,000 cubic meters, and there will be a 1,000-cubic-meter meal hold.
RFC’s requirements were for a vessel with capacity for operation in ice, accommodation for a crew of 139 and a high capacity for high-level processing on board, including surimi production.
MAN Energy Solutions reports that its equipment was chosen on account of its robustness and reliability, and that the power rating and performance of the 14V32/44CR main engine suited the vessels’ operation profile well. Similarly, MAN’s ability to tailor its MAN Alpha propeller to suit the vessels’ operating profile was a huge plus.
Lex Nijsen, Vice President, Head of Four-Stroke Marine at MAN Energy Solutions, said, “Our track record within the fishing segment is very good but we are especially pleased to have won this noteworthy order as the trawlers will be the largest such vessels constructed in the past 25 years. That the customer has chosen an MAN propulsion set-up to accompany its choice of main engine is particularly satisfying and fits well with our strategy of providing system solutions.”
