An FKAB-designed MR product and chemical tanker, ‘Seadevil’, first of six, has been delivered by Xiamen Shipbuilding to German Tanker Shipping.
The 41,000 dwt FKAB T67 vessel incorporates several variations to the standard design for increased performance and compliance with future environmental regulations. than we are used to see on MR tankers.
Special attention has been taken to optimise hull lines including the patented F-bow resulting in energy savings and reductions in CO2 emission over the ship’s life. The vessel is equipped with a 402 kWh lithium titanate battery pack and shore connection for supply of green electricity during port operation.
The propulsion system comprises one medium speed main engine, delivered ready for operation on methanol fuel, coupled to a CP propeller and a shaft generator. The shaft generator can be used for ’take home’ propulsion and is connected to the electric grid via a frequency converter allowing variable speed of the engine and propeller for both PTO / PTI and PTH. In port during discharging the main engine will be used as a generator by a remote operated hydraulic clutch that disconnect the propeller shaft from the sterngear.
The CP propeller system features real-time pitch and speed optimisation, achieving dynamic pitch optimization, boosting propulsion efficiency by over 10% while overcoming the challenge of seamless switching between low-speed ice-breaking while operating in ice zones and normal navigation. Designed to operate in cold conditions of -30℃, the propeller is reinforced and the ice belt area of the hull is strengthened to ensure ice resistance. The intelligent power management system can adjust propeller pitch and speed in real time, seamlessly switch between PTO/PTI/PTH modes, cut fuel consumption by 8%. The vessel has thus been granted the DNV Smart Ship class notation.
