The history of Poly Ice Trawl Doors
Since 1965, Poly-Ice hf., has been producing trawl doors, starting with the traditional V-shaped bottom trawl doors. The company's development and research policy has led to the production of different types of high-quality trawl doors, in response to skippers' requests and different fishing conditions throughout the world.
In mid 1997, more than 7200 Poly-Ice® trawl doors have been produced at Poly-Ice hf.
The company's quality policy for products development and improvement is a very important factor. In close co-operation with demanding skippers through out the world, leads and suggestions are followed for improving quality and performance.
The developement of new trawl doors
In past years, Poly-Ice hf. has developed computerized tests of the hydrodynamic effects of the trawl doors design, carried out by the engineering faculty at the University of Iceland .
Different designs of each trawl door model are tested at the University's computer program for best hydrodynamic results. When best result is achieved, small scale models of the two or three of the best outcome are made and tested in flumetanks with small scale trawls for comparing results and effects. When satisfied result is reached, full size prototype of the doors are made and tested with full size trawl under normal fishing conditions.
At the end of this process, new Poly-Ice ® trawl doors are ready for sale. The result of this co-operation, is probably the most modern and effective trawl doors available today.
