In principle (AIP), DNV received a detailed approval for the Shell International Trading and Shipping Company Limited and Brevik Engineering for the design of a 74,000 Cubic Meter Liquid Carbonide Dioxide (LCO2). The ship was specially developed for the Asian -Pacific market to enable CO2 cost traffic.
Carbon capture and storage (CCS) will play a key role in the decarbonization of industry in the Asian -Pacific area. The emitting countries such as Japan, Korea and Singapore examine the opportunity to send considerable amounts of their own CO2 to store locations in the entire region. This requires the development of larger capacity ships than those currently planned for European CCS projects.
In order to put this in the right perspective, the LCO2 airlines built in Norway for the Pioneering Project Northern have a capacity of 7,500 cubic meters each.
According to DNV, low-pressure freight tank constructions are an important component to commercialize these large LCO2 ships in order to enable the transport of CO2 to lower costs.
This AIP from DNV includes a comprehensive scope in a variety of disciplines, including the evaluation of specific technical challenges for LCO2 airlines. Over 50 documents have been checked, with the focus on the design of the freight tank, including the tank integrity analysis and the suitability of materials.
With dimensions with a length of 290 meters and a 12-meter draft for access to key East Asian ports, the equipped ship reflects the size of a 174,000 cubic knife LNG wearer. It has 15 cylindrical tanks that store 74,000 cubic meters of liquid -CO2 at about -50 ° C and 6–8 bargains, a low pressure industrial standard.
The ship is also designed for the future edging of CO2 from the main motor exhaust gas.
According to DNV, this performance is a significant milestone for the presentation of the viability of innovative grief printing technology for CO2.
“We are pleased to work closely with Shell and Brevik Engineering to bring this innovative gas carrier design into play,” said Mathias Sørhaug, CO2 shipping of Business Development Director at DNV Maritime. “This AIP underlines the importance of common innovations and cooperation in the further development of solutions that support the development of the wider CCS value chain. The scale is important to reduce the CCS costs, and this work shows the feasibility of large CO2 carriers with a low CO2 footprint. “
“After months of technical research, we are proud to have received this detailed approval in principle in order to confirm the feasibility of low pressure with a tender design,” said Lee Teng-Huar, General Manager of Shell, Maritime Operations, Asia Pacific and the Middle East. “We look forward to seeing how innovations like this may improve security, scalability and flexibility to achieve competitiveness in the implementation of cross -border CCS on a large scale.”
Evert Grødal, Managing Director of Brevik Engineering AS, states that the company brought its experience in ship design and CO2 ship logistics with the development of the new low-pressure CO2Xcriner, in which the main philosophy was to reduce the technological risk and to ensure compliance with current regulations.
“Based on a comprehensive technology study that is carried out in cooperation with Shell, this innovative design will probably stop new benchmarks in safe, efficient and sustainable CO2 shipping,” he said.
DNV states that the approval in principle (AIP) is an independent assessment of a concept based on a predefined framework of the requirements. It confirms the feasibility of the design and ensures that there are no significant technical obstacles that hinder its implementation.
