NYK obtains first maritime certification for ambient-temperature containment system

NYK Affiliate Receives Maritime Industry's First Approval for Ambient-Temperature Containment System for Liquefied CO2

Knutsen NYK Carbon Carriers AS (KNCC), an affiliate of NYK, has received a General Approval for Ship Application (GASA) from the Norwegian classification society DNV for its Liquefied CO2-Elevated Pressure (LCO2-EP) containment system.

LCO2-EP technology enables liquefied carbon dioxide (CO2) to be injected into cylinder tanks on vessels and transported at ambient temperature in a stable condition.

Since the liquefied CO2 does not need to be cooled to cryogenic temperatures, LCO2-EP technology can reduce energy and costs incurred throughout the CCUS value chain.

This advancement also enables easier handling of liquefied CO2 until injection into the reservoir, according to NYK.

In April 2022, KNCC’s PCO2 tank system received the world’s first Approval in Principle (AiP) as a technology that can transport liquefied CO2 at ambient temperature.

Following that, KNCC renamed the PCO2 tank system LCO2-EP and conducted rigorous design and talks with engineers, consultants, shipyards, and subcontractors to provide significant paperwork, calculations, and drawings to demonstrate the concept’s potential to meet the GASA.

In addition to LCO2-EP, KNCC is developing low-temperature and medium-temperature liquefied CO2 transport vessels to meet the needs of various projects.

Through these initiatives, the NYK Group will participate in the CCUS value chain and contribute to the future realisation of a carbon-neutral society.
