A 200,000 deadweight-tonne LNG-fuelled bulk carrier may be plying the waves in a shipping lane near you, after the concept design for such a behemoth was completed last week.
Shipping line Nippon Yusen Kabushiki Kaisha (NYK) and engineering company Japan Marine United Corporation (JMU) carried out the concept design work for the bulker; the design has passed inspection by ClassNK and obtained approval in principle.
Using LNG as a main fuel is said to reduce greenhouse gas emissions by as much as 30% compared with conventional heavy fuel oil, with sulphur oxide emissions cut by close to 100%.
JMU created the vessel’s basic design based on previous designs of similarly sized bulkers, which are fuelled with conventional heavy fuel oil.
The arrangement of the LNG fuel tank and the fuel supply system equipment allows the ship to increase its cargo hold volume and reduce fuel consumption in comparison to a conventional bulk carriers of the same size, despite the weight increase caused by additional equipment.
The ship’s concept design was given an AiP by ClassNK, and NYK and JMU can now begin negotiations with customers for large LNG-fuelled vessels capable of reducing environmental loads.
