Knud E. Hansen wins DNV AiP for type-C liquified CO2 tank design

Danish naval architect company Knud E. Hansen has received approval in principle (AiP) from classification society DNV for the design of a type-C liquified CO2 tank.

The tank has been designed as part of the design of a liquified CO2 carrier. The work has been carried out for energy company Ineos Energy as part of Project Greensand. The project involves capturing CO2 from CO2 emitters at shore which is then stored under the North Sea.

According to DNV, intensive use of FEM has been applied for analyzing all aspects of the tank to the satisfaction of the classification society.

Knud E. Hansen has been responsible for the following elements of the liquified CO2 carrier:

🔹 Ship design including DP2 and bow/turret unloading system integration;
🔹 Waste heat management for improved OPEX during CO2 conditioning;
🔹 Design of type-C tanks to the approved in principle stage;
🔹 Process system to condition the CO2 and injection it with high pressure into the reservoir;
🔹 3D model for coordination of cargo deck layout.

To remind, in April last year, the Danish firm revealed a new tanker vessel design, made specifically for the transportation of carbon dioxide (CO2).

According to Knud E. Hansen, the new tanker design will feature a range of cutting-edge technologies and design elements that are tailored to the unique requirements of CO2 transport.

The CO2 carrier will be a DP-2 ship with an anchor loading system. It will have tanks for storage and transfer equipment for the off-loading and optional heating of CO2 to pressure and temperature for the underground injection site.

The vessel’s hull will be optimized for stable and efficient navigation through the water, while its cargo tanks will be heavily insulated and reinforced to withstand the high pressure and low temperatures required for storing CO2 in liquid form.
