A new standard of line hauling
"The line is set where the fish are, not according to the weather forecast. The boat is kept in position with wind in the stern. We pull the line when others are backing against the wind, and we save fuel by using step II on the gear, thereby driving the propeller at a lower speed.
This is the specific feedback from several ship owners.
Manoeuvring a longliner during fishing set great demands on accurate positioning related to the line. Just a few meters out of position increases wear on the line, and reduces the catch significantly. This is especially true in bad weather on shallow fishing grounds. A longliner must be able to operate in storm and harsh weather, regardless of wind from any direction.
Over the years, Brunvoll, in close collaboration with ship owners and designers, has developed unique systems for accurate and economical manoeuvring, especially adapted to longline vessels. A longliner pulls a line perhaps 80% of the time, with low speed and little load on propulsion, but with high demands on keeping the position and course.
The unique solutions with 2 speed gearbox in combination with a retractable azimuth combi thruster in the foreship have been a success for our customers in this segment.
