The Ternsund class is a series of four product and chemical tankers with LNG propulsion. The ships were built in China by AVIC Dingheng Shipyard for the Danish shipping company Terntank and put into service from 2016. The four ships are called Ternsund , Ternfjord , Tern Sea and Tern Ocean . The design comes from Rolls-Royce Marine AS and is called Type NVC 615 CT.

construction

The double-hulled ships with a deadweight of almost 15,000 tons have a vertical stem with a bulbous bow and a transverse thruster . The 16 tanks for chemicals and other oil products hold 16,559 m³ at 98% full. The deck is designed as a trunk deck . On the front third there are two LNG tanks with a total capacity of 630 m³. The deckhouse is at the very aft. The storage tanks built into the fuselage are the gas oil tanks with 630 m³, ballast tanks with 6636 m³, slop tanks with 242 m², fresh water tanks with 325 m³ and a urea tank for exhaust gas cleaning with 52 m³. The cargo is transported in 16 coated cargo tanks. A nitrogen generator with an hourly output of 100 m³ is installed in the engine room, and a 20 m³ buffer tank is also available for handling. Inert gas to pressurize the cargo tanks is generated by an oil-powered boiler with 3950 m³ / h. Deepwell pumps with a capacity of 450 m³ / h are installed for loading and unloading. In front of the deckhouse in the area of ​​the manifolds there is a hydraulic crane to take over the hose.

drive

The drive is provided with a Dualfuel- Wärtsilä - two-stroke engine of the type 5RT-flex 50 DF, of 5.850 kW at 102 min -1 guaranteed. As auxiliary diesel three Mitsubishi MAS 850-S are installed, the 790 kW at 1800 rpm -1 afford. A transverse thruster type 1650 AUX CP with 865 kW power is installed as a maneuvering aid. In addition, there is a shaft generator with an output of 780 kW. Consumption is given as 8.9 t of LNG in 24 hours. Exhaust gas cleaning is carried out by selective catalytic reduction (SCR) in accordance with the Tier 2 exhaust gas standard with catalytic converter and urea injection.

environmental Protection

Operation with LNG greatly reduces emissions. 99% less SO X , 97% NO X , 40% CO 2 and 99% particles are emitted. The ships in this series were awarded the “International Green Shipping” award on October 17, 2016 in Rotterdam.
