The German Federal Maritime and Hydrographic Agency (BSH) is expected to will take delivery soon of the LNG -powered 75-metres long survey vessel “Atair”.
The newbuild features propulsion and manoeuvring systems from the German Schottel Group.
These included a Schottel Pump Jet type SPJ 220 (1,000 kW), one Schottel Transverse Thruster type STT 1 FP (330 kW) in the bow and one Schottel Transverse Thruster type STT 170 FP (200 kW) in the stern.
The research vessel was being completed at the Fassmer yard on the west bank of the Weser river, 25 kilometres northwest of the North Sea port of Bremen, for handover to the BSH.
The LNG-fueled ship has a large 130 cubic-metre tank onboard which enables the ship to run on LNG alone for 10 days.
“When opting for diesel operation (dual fuel), high-quality diesel fuel oil with a sulphur content less than 0.1 percent is used,” said Fassmer.
Hamburg-based LNG supplier Nauticor took care of the purchase and transport of the LNG for the first filling of the tanks of the “Atair” and assisted Fassmer with the first fuel load.
Nauticor also ensured LNG supply during the entire testing phase and the successful initial bunkering of the “Atair” in February 2020.
The ship is to be put into service in the first half of 2020 to replace the previous “Atair”.
Equipment onboard includes several laboratories, a station for measuring air pollution while at sea, a crane, a bridle beam for geological activities on the seabed, a large 200s square metres work deck and extensive diving equipment, including a diving chamber.
The vessel’s underwater noise has been optimised to meet the DNV Silent Class Notation (SILENT R). The Schottel propulsion units are also designed to have low noise emissions.
