The company Tsuneishi Shipbuilding has completed the delivery of its first Kamsarmax bulk carrier equipped with dual-fuel technology, a unit that uses liquefied natural gas as its primary propulsion.
The Kamsarmax Bulk Carrier and its Total Fuel Control
Located on the stern deck is a Type C independent pressure tank designed for storing fuel at extremely low temperatures. These tanks were manufactured entirely at Tsuneishi’s facilities.
The company has perfected complex precision welding and thermal insulation processes. Furthermore, previous experience in the production of LPG vessels has enabled the shipyard to master the management of specialized materials for cryogenic environments.
The hull design and the integration of a shaft generator allow this vessel to far exceed international regulations. The vessel achieves a reduction of more than fifty percent in the Design Energy Efficiency Index. This mark easily surpasses the Phase 3 requirement demanded by the industry for the coming years. The use of liquefied natural gas reduces carbon dioxide emissions and almost completely minimizes sulfur and nitrogen oxides.
The technology developed to handle pressures and low temperatures serves as a foundation for the future use of other alternative fuels. The knowledge acquired in handling cryogenic substances will facilitate adaptation towards ammonia engines. This technical vision ensures that the maritime industry has proven tools to achieve the goal of zero emissions in heavy cargo transport.
