Damen Marine Components has delivered a new 19A nozzle for the Maartje Theadora, one of the largest fishing vessels in Europe. This type of nozzle gives more thrust at low speeds, which is ideal for fishing. The Maartje Theadora was built in 2000 as a freezer trawler for Parlevliet & Van der Plas, the biggest fish-processing company in Western Europe. The 140-meter-long vessel has large freezer rooms where fish is frozen immediately after it has been caught and cleaned. This means that a freezer trawler can stay longer at sea. After more than twenty years of active service, the original 19A nozzle looked ready to be replaced. The nozzle, which has a diameter of 4,340 mm and a propeller diameter of 4,300 mm, was recently replaced by its exact equivalent at the Damen Shiprepair Amsterdam shipyard. The Maartje Theadora is already back in service again. A nozzle has a positive effect on the performance of a fishing vessel. A ship that has its nets in the water during fishing, is affected by resistance and needs more thrust. At the lower speeds that the ship maintains while fishing, the nozzle can generate more thrust. Added benefits are reduced fuel consumption and lower CO2 emissions as a result.
