The CNP Freire yard in Vigo has delivered the second of two trawlers completed this year for owners in Greenland.
The Rolls-Royce-designed Polar Nattoralik was delivered this week following sea trials, and he naming ceremony was held at the yard the next day, attended by representatives of both the yard and the owner, Polar Seafood.
Earlier this year the yard delivered sister vessel Markus to Qajaq Trawl. Both trawlers are designed to fish for and freeze shrimp caught in Arctic waters. Polar Nattoralik has an 80 metre overall length, with a 17 metre beam and has a 2100 cubic metre fishroom capacity.
‘The shipyard’s management is very pleased with the results of these vessels, which have helped Freire strengthens its worldwide reputation as shipbuilders of highly sophisticated fishing vessels,’ a spokesman for the Freire yard said.
‘One of their most important characteristics is their high level of automatisation and efficiency in terms of fuel consumption.’
Built to Rolls-Royce’s NVC 375 design, Polar Nattoralik and Markus are designed with operational efficiency, low emissions, crew comfort, safety and excellent seakeeping capabilities as the main considerations in the development of the ship design and equipment package.
As well as the design of the 80 metre Polar Nattoralik, Rolls-Royce also delivered an equipment package that includes the nine-cylinder Bergen B33:45 main engine, propulsion system, automation, winches, steering gear and a power electric system.
A Promas system integrates the propeller, a hubcap, rudder bulb and the rudder itself into a single hydrodynamic efficient unit. A Hybrid Shaft Generator (HSG) is also part of the package, providing an advanced power system that enables a much more flexible use of engine and propeller speed variations to maximise both propeller and engine efficiencies, which contributes to the reduction of CO2 and NOx emissions.
Deck equipment consists of low pressure hydraulic main winches with electric auxiliary winches.
