Leading Journal of the Irish & UK Fishing Industries

Founded in 1967, Thyborøn Trawldoors continues to pave the way for innovation and efficiency in the fishing industry, supplying fishermen across the world with top quality, tailor-made trawl doors to suit pelagic, semi-pelagic and bottomfishing vessels.

In co-operation with fishermen and technical experts from the leading flume tanks in the world, Thyborøn Trawldoor is currently attempting to further improve and develop the trawl doors, culminating in the recent launch of their new fully controllable Bluestream controllable trawl doors on the market.

Taking great pride in quality assurance and efficiency, the company carried out tests of the new product on board Swedish pelagic vessel Themis over a long period to finalise and perfect the design.

“We are satisfied with the feedback from Themis and we have now made them 100% available commercially, and we’re open to supplying and customising systems for each of our customers who need a set of controllable doors,” said the company’s Henrik Andreassen.

A second set of tests were carried out on board Shetland pelagic vessel, Serene, while it was in Skagen for annual maintenance. The successful outcome of the tests meant that the vessel was not only supplied with a 15 square metre pair of Bluestream doors, but it also returned home with a second pair on board for Antares.

Among the many advantageous features of the new Bluestream doors, is the ability to pre-set the depth, while also controlling the doors during a tow via the wireless communication system.

“The feedback from Themis was that this is very beneficial. When the crew are asleep, and the skipper wants to make a small adjustment during the night, he can just change the setup on the trawl doors without having to wake up four or five guys,” explained Henrik Andreassen.

He added that the surface area and spreading force of the trawl doors be changed by up to 27% can with this system.

“With a set of 15 square metre doors, you have every size covered all the way down to 10,95 square metres,’ he said.

“This becomes extremely useful for the vessels operating across different fisheries. A further important feature is that with these doors, you avoid any danger for the crew when adjusting the doors, since it can now be done remotely from the wheelhouse.”

Highlighting Thyborøn Trawldoors position as one of the leading global brands in the industry, Andreasson explained, “The flexibility in our production and among the staff allows the company to offer “tailor-made” trawl doors, which are built to the individual customer needs, wishes and demands.”

Visitors will have the opportunity to witness the scale model Thyborøn Trawldoors Bluestream doors first hand at the Irish Skipper Expo, with the team showcasing 3D videos of the product in action and providing expert information.
