The rebuilding of a Kockel Fish Vessel into a small 300MT freighter.

This Kockel Fish Vessel "CatJan" Fish register no. LO-13






Principle dimensions:

Length o.a. = 44.5 m

Breadth o.a. = 12.0 m

Depth moulded = 1.55 m

Dead weight = 169MT

Draft = 0.35 m

After the rebuilding the vessel has a new deck of frames in the middel of the vessel and Dragline Pannels will be used for closing the deck when the freight is Sand etc. With open frame deck the vessel can be used as small Dredger. It can open in the middel hydraulicly a big Gate Valve DN600mm to unload the dredg.


 Sand Trucks can drive via a Ramp on board of the CATJAN. max weight 40ton



The vessel is high maneuverable with three (3) Schottel Pumpjets PJT57 who can turn 360 degrees. Average speed is approx 7/8 knots

The new owner is Frachtschifffahrt Jan Christiansen from the island Föhr, Northern Germany

Multi purpose Shelter Deck Trawler

The shelter deck trawler is built for a Dutch client and he wanted to be able to fish with Beams, Trawl, Outriggen and Twinriggen. Therefore we designed together with the client a (for the Netherlands) new type of shelter deck trawler with a hull from shipbuilding steel Grade A and a shelter deck and wheelhouse from highly seawater resistant Aluminium 5083 H111. The propulsion will exist out of two (2) Diesel Electric driven propeller shaft and propellers with a diameter of 1700mm complete with nozzles with a maximum bollard-pull of 9.000kg. The vessel will have good maneuverability because of the two (2) propulsion systems and this is important for this type of fishing. The total length of the trawler is only 23.99 meter, and this is below the 24 meter limit for Euro-trawlers. The total propulsion power is two (2) times 111kW (150 Hp) is 222kW (300Hp) and this is also a limit for Euro-trawlers. The advantage of a Euro-trawler is that she is allowed to fish within the 12 miles zone. (coastal zone).

The power supply for the electric motors of the propulsion system comes from two (2) generator sets. One set consist of a Scania DS16 diesel engine with one generator with a capacity of 425kVA-400/230V, 50Hz at the flywheel housing and a 120kVA 400/230V, 50 Hz generator on the PTO at the front of the engine. The second set consist of a Scania DS12 diesel engine with one generator with the capacity of 315kVA 400/230V, 50 Hz at the flywheel housing and a 120kVA 400/230V, 50Hz on the PTO at the front of the engine. The vessel can sail and fish at only one generator set, but the generators board electricity can run parallel and load sharing and start-up automatically if the electric power demand is to much for one generator set.

The fish trawler "Grietje" is mainly fishing at shrimps and langoustines, but can also fish at turbot,sole, and plaice. Because the vessel has a diesel electric propulsion and so much thrust, she will be able to save approx 40% fuel consumption, when she is fishing at shrimps. An other advantage of the shelter deck trawler is, that she will be able to do heavy fish methods with 9000kg thrust. One of the most important advantages of the electric driven propellers is, that the electric motor can deliver at a low speed already full power and therefore the motor can follow exact the propeller power curve.(power demand of propeller)

The vessel has also a special designed fish winch with six (6) wire drums, capacity 500 meter wire diameter ø20mm each drum, for the fish lines and two (2) wire drums, capacity 80 meter wire diameter ø16mm each drum, for the beams. The winch is driven by an electric motor of 110kW.

The capacity (75m³) of the fish hold is quit big for a 24 meter long and 6.6 breath fishing vessel and has cooling to zero degrees and an ice machine.



This is the 3D impression of the hull of the new Multi Purpose Shelterdeck Trawler, made by Tobias Nagel, MARVIS, Groningen.

The shipyard IBIS, at Warena, Friesland/Netherlands has started with building the hull of the trawler at the 9th of April 2007.

On Monday, October the 1st 2007, the hull with super structure of the WR-189 "Grietje", has been launched into her environment. The generatorset, electric motors, frequentie control boards, electric switchboards, reduction gearboxs, propeller shafts, propellers with nozzles and rudders are already installed. The fish winch is also installed in the winch room.


The wifes of the young owners of the new WR-189 "Grietje", V.O.F C.A. van Eekelen and Sons, have christen with champagne the vessel before lifting her into the water.

and they were successful with the first swing. The champagne bottle broke immediatly.

The crane is designed by our self and constructed and build by W. Das Consultancy and Bos Construction

The WR-189 back in the harbour of Den Oever. Within two or three weeks ready for the final sea trials.

Ready for the sea trials. The vessels only need some ballast in the front of the vessel to trim the vessel.

June the 12th 2008 we have don the sea trials for the Dutch authorities, to prove that the propulsion will not exceed the 2x 111kW during fishing. This is measured at the propeller shaft and after the trials the control panel of the frequentie controler is sealed by the authorities(total 221kW)

Roeleveld from Scheveningen is insulating the fish hold and making the walles of a special pannels with a very high insulating quality

Also the cooling installation is designed and delivered by Roeleveld. Here you see the frosters with the ventilation fans.

Scheepstimmerbedrijf Schrier Den Oever ( is insulating the crew accommodation and has started the make the panneling and interior for cabines, galley and shower/toilet area.

Plug en de Boer are the suppliers of the whole propulsion system. (shafts, propellers and nozzles)

The winch for the fishing lines has been delivered by Luyt B.V. The weight of the winch is 8 ton and it is approx 2,7m by 3.5m and 1.8m high

The window frames and extra thick double glassed windows are delivered and installed by Scheepstimmerbedrijf Schrier from Den Oever (  They ordered the window frames from HORA

The propulsion set, electric motor and gearbox, are in the engine room, ready fo installing and lining.

The hydrofore, cooling- and ice machine are already installed in the winchroom.

 Now the owner with his sons have to finnish the built-in with the technical assistance of Lasbedrijf Jonkman and other subcontracters as, Sandfirden Technics, Tijsen Elektro, Scheepstimmerbedrijf Schrier, Couperus Hydraulic and Luyt b.v. The planning is April 2008 ready for fishing


Latest project (summer 2006)


The present project is the new building of a German shrimp-trawler, "Anika" with the German fish-registration number "PEL-2" and with the following main dimensions:

L.o.a.    17.95 metre

Width      5.75 metre

Depth     2.25 metre    and with a draft of approx 1.50 metre

 The hull is made of shipbuilding steel Grade A and the superstructure of highly seawater resistant aluminium 5083 H111.

I have contracted Luyt B.V in Den Oever for the building of the hull with superstructure under my supervision. The propulsion exist out of a Deutz 221kW (300Hp) diesel engine with a Reintjes gearbox and with a oil lubricated propeller shaft and a cunial 5 blades propeller with nozzle of  Plug & de Boer .

The shrimp-trawler is builded according to the German See B.G. ( Germanische Lloyd) regulations and the hull with superstructure will be ready in August 2006. The German company Maschinenbau Lorenzen in Husum will finalize the build-in of the equipment.


The  "Anika"in her environment and after later towed to the German harbour-city Husum for completion. The planning is that the shrimp trawler will start fishing in the beginning of November 2006.

Up in the air.


Since the 20th of April 2007, the fishtrawler "Anika - PEL-2" is complete finished and started to fisch on shrimps in the German coastal waters. It took the company MB- Lorenzen in Husum approx 7 months to finish the trawler, but during the winter-time, they worked on other projects.



Project Fast Day-Fishing Boat

This fast day-fishing boat is builded in 1999 by Luyt B.V. in Den Oever, when I was at that time the technical commercial manager and responsable sales and production.

The day-fisher was very complete as you already can see on the picture. It was equiped with a complete fish procesing system and has even a Polyester fish-hold. The speed was 20 miles/hour at that time, despite the weight of the boat. In the forpiek is a small complete living quarter with audio/TV and with two (2) beds (bunk bed). Even a small badroom with washbasin, toilet and shower. In the wheelhouse is corner with mess and cooker, magnetron oven and sink unit. The engine room is equiped with a 440kW (600Hp) Caterpillar diesel engine with gearbox for the propulsion of the propellerand a small Gen-set, 230/400 Volt, 10kVA, 50Hz. It has even a CO2 fire-figthing system for the engine room on board.
