Ship rudder design fishing vessel business case

By: Jeroen Berger, July 10, 2017

The fishing vessel LH 356 ‘Henk Senior’ will be transferred from the Spanish shipyard Nodosa Shipyard to Louwe de Boer from Osprey Trawlers in Urk (the Netherlands) in the beginning of March of 2017. The Twin Rigger/ Fly Shooter is 28,7 metres in length, 10 metres in width and has cavities of 4,51 metres (main deck) and 6,86 metres (shelter deck). It was the challenge to give this fishing vessel an environmentally friendly look. Our Spanish partner VICUSdt has been selected as the supplier for a CFD optimized ship rudder design for this fishing vessel.


What was the challenge with the LH 356 ‘Henk Senior’?


Osprey Trawlers, together with three other companies, is part of Osprey Fish; the company of one of the oldest Dutch fishing families: the De Boer family. This family have sailed the seas for generations. Once in small wooden sailboats, and nowadays with a modern, seaworthy fleet. Because they want to maintain the fishing sector on the North Sea for now and for the future generations, they are deeply committed to sustainable fishing. For the LH 356 ‘Henk Senior’ the concept of sustainability had to be expressed.

How have they addressed this challenge?


As a family business, they have taken the lead to provide their fleet, and so for the LH 356 ‘Henk Senior’ too, with the MSC certificate. MSC stands for Marine Stewardship Council, which is an international non-profit organization established to address the problem of unsustainable fishing and safeguard seafood supplies for the future. The LH 356 ‘Henk Senior’ catch therefore bears the label "Certified Sustainable Seafood", guaranteed by the Marine Stewardship Council. A guarantee for the consumer that their fish has been caught in a socially responsible manner.


What has VICUSdt been able to contribute to this?


In the field of sustainability, VICUSdt has optimized the ship rudder from the LH 356 ‘Henk Senior’. By making use of advanced Computational Fluid Dynamics (CFD) calculation techniques the cavitation-rudder angle will increase and the resistance will reduce.



What was the result of VICUSdt’s work?


VICUSdt’s CFD optimized ship rudder design leads to a lower environmental footprint, a reduction in operational costs and will contribute to a better competitive edge for Osprey Trawlers.
