The owners of Faroese pelagic vessel Finnur Friði, Gøta-based fishing and processing company Varðin, were early adopters when it came to synthetic trawl warps.
The 76 metre pelagic vessel has been one of the Faroese fleet’s consistent top catchers since it was delivered in 2003, and the first set of Hampiðjan’s DynIce warps were spooled onto its winch drums back in 2007. Now they have come back to Hampiðjan for their third set of DynIce warps, having ordered 2300 metres of 38mm warp for each winch drum,
“We’ve been very satisfied with the DynIce warps ever since we first had a set in 2007. These warps have performed extremely well in pelagic trawling over the years and they last an average of seven years, which is excellent, taking into account that we get a year and a half out of steel wire warps with the same diameter and breaking strength,” said Finnur Friði’s skipper Andri Hansen.
“We still have the older warps on the drums underneath and right after the blue whiting fishery ends in the summer we expect to spool a new set of warps onto the winches that cope well with the tensions of working with DynIce warps,” he said, adding that the Brattvaag winches cope well with the tensions involved in working with synthetic warps.”
He explained that the warps perform exactly as they are intended to, and lie in a direct line to the doors, while the significantly heavier steel wire warps lie in a half-loop from the stern and then upward to the trawl doors.
“So the DynIce warps don’t spook the marks before the trawl and the doors reach the fish. That’s the reason why marks make their way more easily into the trawl with DynIce warps,” he said.
“When we fish for mackerel close to the surface it’s very easy to keep the pelagic trawl high in the water column when the mackerel are 40 to 50 metres below the surface. At shallow depths we can shoot away a lot more DynIce warp than we could with steel wire, so we get a good horizontal opening. We often see the warps are clear of the water when the doors are high in the water or at the surface. That’s because the DynIce warps are forty times lighter in water than steel wire. We have also repeatedly seen over the years that due to the light weight of these warps, there is virtually no maintenance needed to the trawl blocks and rollers on board,” Andri Hansen said.
He commented that when working in deeper water, such as on blue whiting at around 600 metres, they need to shoot 200 to 400 metres more warp than the trawlers using steel warps, as well as having to use toe-end weights that are 1000 to 1500kg heavier so that the trawl opens correctly at those depths.
“In comparing DynIce warps with steel wire warps of the same dimensions, it’s clear that DynIce warps are lighter to tow, so there is lower fuel consumption per towing hour. I can safely say that choosing DynIce warps back then was an investment that has paid itself back many times over for the company in terms of more economical operation,” Andri Hansen said.
