DNV GL has presented Oshima Shipbuilding Company with an Approval in Principle (AiP) certificate for an LNG-fuelled Kamsarmax bulk carrier.
The new, innovative design has been found to comply with DNV GL class rules and all current and upcoming regulations, including the new emission control regulations and the draft IGF Code for fuels with a low flashpoint.
U-Shaped Superstructure
As space on deck is limited on a bulk carrier, Oshima's design features an innovative solution: the ship’s superstructure has a U-shape that can accommodate the LNG tank in its centre. This approach allows the accommodation deck house to be completely separated from the LNG storage tank and scalability in terms of the amount of LNG storage onboard. Meanwhile, a tank cover adds an additional safety barrier and ensures compliance with the draft IGF Code. The bunkering stations for LNG, heavy fuel oil (HFO) and marine diesel oil are located at the side of the accommodation deck house.
The Kamsarmax vessel is designed for dual fuel operation, using both LNG and HFO to power the main engine, the generators and the boiler.
