South Korea-based Samsung Heavy Industries (Shi) has secured approval in principle (AIP) from the Norwegian classification society DNV for the design of a new liquefied CO₂ (LCO₂) carrier.

The new carrier will feature customised large cargo tanks (pressurised International Maritime Organization (IMO) Type-C) as well as a cargo handling system with reliquefication technology.

DNV granted the AiP after evaluating SHI’s design against the needs of the IGC code as well as its own guidelines for CO₂ carriers.

SHI’s new system is anticipated to meet future large-scale CO₂ transportation demands, which are increasing due to the development of several carbon capture, utilisation and storage (CCUS) projects.

Featuring optimised cargo space, the ship will also use customised bi-lobe cargo tanks to improve its performance.

The reliquefaction system uses a refrigeration process enable to condense vapourised and compressed CO₂. The CO₂ is cooled and returned to the LCO₂ tanks after expansion.

SHI shipbuilding sales engineering head and vice-president Young Kyu Ahn said: “We are happy to collaborate with DNV in this important design development and believe this AiP award demonstrates SHI’s readiness for the new LCO₂ shipping market that is coming from global decarbonization demands.”

Meanwhile, DNV has entered into a memorandum of understanding (MOU) with Daewoo Shipbuilding & Marine Engineering (DSME) for the development of a wind assistance propulsion system.

The partnership will focus on the development of wind-assisted propulsion systems for ships, including a rotor sail solution and fuel-saving device technology.

The main tasks include DNV’s Type Approval Design Certificate (TADC) and technical support for the future DSME rotor sail system.

The two entities will also carry out a study of a Wind Assisted Propulsion System (WAPS) on deep-sea vessels, such as LNG carriers and very large crude carriers (VLCC).
