Keppel and DNV GL team up to promote LNG as a ship fuel

Classification society DNV GL and Keppel Marine and Deepwater Technology (KMDTech), a subsidiary of Keppel Offshore & Marine (Keppel O&M), have signed a framework agreement to boost the uptake of liquefied natural gas (LNG) as ship fuel.

The agreement covers potential newbuilding projects including LNG bunker vessels, small-scale LNG carriers and floating storage regasification units (FSRUs), as well as LNG related assets employing battery and hybrid technologies.

As the first delivery in the agreement, DNV GL will issue Approval in Principle (AiP) certificates for two LNG bunker vessel designs from KMDTech:

  • a 7,500 cbm small-scale LNG carrier with bunkering capabilities and

  • a 7,500 cbm small-scale LNG carrier with bunkering capabilities and hybrid battery propulsion.

The LNG carriers are each designed to carry up to 7,500 cubic meters of LNG in Type C-tanks. An optimized deck arrangement for the modular LNG gas supply, filling and safety systems increases the cargo capacity and efficiency of the vessels. They are equipped with engines that can run on both diesel and LNG, and will also have a class notation for bunkering which enables the provision of LNG bunkering services if required.

In light of the upcoming IMO 2020 SOx regulations, LNG as marine fuel is viewed as one of the most viable options for deep-sea shipping. DNV GL’s Maritime Forecast to 2050, part of the research behind the DNV GL Energy Transition Outlook 2018, projects that more than 10% of the world’s shipping fleet will be powered by LNG by 2030, compared to less than 0.3% in 2019. The report anticipates that LNG-powered vessels will make up 23% of the world’s fleet by 2050.

In order to support this growth, an upgrade of LNG bunkering infrastructure is needed.

One of the objectives of our collaboration with Keppel is to facilitate the increased supply of LNG bunkering infrastructure by being future ready through design approvals of different sizes of LNG bunker vessels, and LNG-related assets such as small-scale LNG carriers and FSRU.

—Johan Peter Tutturen, Business Director Gas Carriers in DNV GL

The collaboration is also intended to further advance asset design by optimizing machinery and systems configuration to increase fuel efficiency, using advance simulation tools such as DNV GL’s COSSMOS.

Additionally, the parties will work together to establish round table discussions involving all stakeholders in the LNG-as-fuel value chain, including gas and LNG bunker suppliers, designers, shipbuilders, shipowners and operators, in an effort to increase the uptake in demand for LNG bunkering in Singapore and beyond.

The design and engineering collaborative office will be located at KMDTech Singapore, with Keppel O&M’s yards to undertake the project execution.
