Uzmar Shipyard has launched a harbour tug for the Danish Port of Aarhus, an escort tug for Smit Lamnalco and delivered an emergency response vessel for Kuwait Oil Co (KOC)
The Turkish shipbuilder held a launching ceremony for azimuth stern drive (ASD) tug Hermes near the end of June. An ice I class tug with mechanical-hybrid propulsion, it was built to a Robert Allan RAmparts 3000 design, with delivery expected in Q3 2021.
Uzmar will install a pair of Cummins QSK60 engines, compliant with IMO Tier II emissions requirements, each developing 2,013 kW of power to drive two Schottel RudderPropellers type SRP 430 azimuth thrusters with fixed-pitch propellers of 2.5 m diameter.
An additional driveshaft links the port and starboard thruster units for Schottel’s Sydrive-M mechanical hybrid solution which allows one engine to be shut down when the tug is not assisting a ship, while the other engine provides power to both thruster units. Hermes will have free-running speed of 12.5 knots and bollard pull of 65 tonnes.
In another configuration, power from the starboard engine can be dedicated to a large fire pump mounted to the front end of the engine. At the same time, port engine power is committed to both thrusters giving the master full manoeuvring control of the tug while holding it in the best position for fire-fighting.
Uzmar said Hermes will ensure greener operations and higher efficiency when it goes into operation in Denmark’s largest container port.
In mid-June, Uzmar launched the first of three ASD escort tugs it is building for Smit Lamnalco’s operations in east Africa. These 42-m tugs are being built to Robert Allan’s RAstar 4200 design and Bureau Veritas class to support gas carriers at an LNG terminal under construction in Mozambique. They will provide services for the Coral South floating liquefied natural gas project from Q2 2022.
These ASD tugs will be powered by ABC 12 DZC main engines, developing 2,900 kW of power at 1,000 rpm, driving Kongsberg US 35 azimuth thrusters with a controllable-pitch, 3-m diameter propeller giving a bollard pull of 95 tonnes and speed of 13 knots.
Earlier in Q2 2021, Uzmar delivered an emergency response vessel to KOC. KOC Al Zour was built to Robert Allan’s RAmpage 6000 design and Lloyd’s Register class rules, as the biggest vessel completed by Uzmar. It is equipped to conduct oil spill containment and recovery and secondary duties including offshore fire-fighting, search and rescue, logistics supply duties, surveillance, towing and general offshore support services.
At 1,803-gt, it has an overall length of 60-m and a beam of 14 m. Two Yanmar main diesel engines each develop 1,620 kW of power giving KOC Al Zour a maximum speed of 13 knots, a cruising speed of 8 knots and a bollard pull of 30 tonnes.
