Bi-lobe LCO2 carrier tank design granted AiP by DNV

Using an abundant, if toxic, resource to power the maritime fleet.	A mature future fuel already in use - but will it become dominant?	Numerous NGOs protested against the IMO earlier this year putting biofuels in its Global Fuel Standard, but the “fuel versus food” debate seems to have been solved by deriving fuels from waste.	Technically the cleanest possible fuel source available to the maritime world and one that has the longest history, dating back to the 1950s. Why is it not in common, non-military use?	LNG is currently the most popular lower carbon fuel, but with bio and e-LNG it could move beyond its current transition fuel status supported by extensive existing infrastructure.

A 70,000 cbm liquefied carbon dioxide (LCO2) containment tank developed by Hanwha Ocean for an LCO2 carrier has been awarded an approval in principle (AiP) from DNV at the Gastech 2023 conference in Singapore. The cargo design integrates Hanwha Ocean’s Bi-Lobe cargo hold, a vertical structure that maximises cargo capacity.

The 70,000 cbm LCO2 carrier design concept specifically incorporates LNG propulsion engines and allows sufficient space for installing shipboard carbon dioxide capture and storage systems, enabling compliance with various environmental regulations. While setting the carrier apart from conventional designs, Hanwha Ocean’s design adheres to DNV’s rules and the International Maritime Organization’s IGC Code.

URN measurement

Alongside the AiP, DNV also awarded Hanwha Ocean an Approval of Service Suppliers (AOSS) for an underwater radiated noise (URN) measurement system. The AOSS - the first for a Korean shipyard for an underwater radiated noise (URN) measurement - comprises both near- and far-field URN measurements and analyses. The near-field URN measurement system offers the convenience of self-measurement in an attachable form, boasting enhanced usability and cost-efficiency.

JongSeo Kim, COO of Hanwa Ocean, said, “We are delighted to achieve these milestones in partnership with DNV. As countries and ports increasingly offer incentives for ships adhering to underwater noise regulations, we are well-positioned to provide ship owners with innovative low-noise ship design technology, contributing to a more sustainable maritime industry.”

“DNV is proud to collaborate with Hanwha Ocean in pushing the boundaries of maritime innovation. These accomplishments signify remarkable leaps in the industry’s pursuit of heightened safety, sustainability, and operational efficiency. DNV continues to play a pivotal role in shaping environmentally responsible vessels that adhere to rigorous industry standards, and we celebrate these strides toward a more sustainable maritime future,” said Vidar Dolonen, Regional Manager of DNV Korea and Japan.
