Nordlaks in Stokmarknes, Norway, is building a 385m long and 60m wide offshore salmon farm and has ordered a new hybrid/LNG live fish carrier (wellboat), with Rolls-Royce providing the equipment for both newbuilds. The ships have been designed by NSK Ship Design.
Rolls-Royce will supply six TT1100 tunnel thrusters to the massive fish farm, which has been designed to produce salmon further offshore. The thrusters will circulate water both inside and underneath the cages in which the fish stocks are held.
This will be the first time that thrusters are supplied for this kind of use, as they are normally, they are used for ship propulsion, Ottar Ristesund, Rolls-Royce, SVP Propulsion Sales – Marine, mentioned.
In addition, Nordlaks has also ordered a new, environment-friendly wellboat to transport live salmon from the offshore fish farm to the onshore processing facility. The wellboat will have four LNG engines, as well as propulsion and Dynamic Positioning (DP) system from Rolls-Royce.
"In addition, they [Nordlaks and NSK Ship Design] have specified a propeller solution that provides the best possible manoeuvrability – whether the vessel is serving traditional fish farms in Norway’s fjords or the new installations located in rougher waters offshore ... The vessel produces low emissions and will run efficiently for many years."
