BV and partners explore CCS unit installation on operational ships

Two types of bulk carriers in the Wah Kwong fleet will be the study’s focus.

French classification society Bureau Veritas (BV) has collaborated with Wah Kwong and Shanghai Qiyao Environmental Technology to conduct a feasibility study on the deployment of carbon capture and storage (CCS) units on existing vessels.

The cooperation agreement was signed by the entities as part of their efforts to meet 2030 Carbon Intensity Indicator (CII) goals.

Two types of bulk carriers currently in service in the Wah Kwong fleet will be the focus of the study.

Qiyao provided a customised CCS unit design and submitted relevant drawings for the Wah Kwong fleet based on the specific design parameters of the vessels.

BV assessed the plans according to existing regulations to ensure that the safety of the ships and equipment would be maintained and that the carbon emission reduction targets would be reached during the ships’ operation.

Qiyao used its CCS concept to complete the laboratory testing, where, so far, it has achieved a total carbon capture rate of more than 85%. It is still in the process of continuous optimisation.

The CCS unit can also be adapted for different ship types and sizes. Its design approval is currently under assessment.

The system includes an absorption unit, separation unit, compression unit, refrigeration unit and storage unit.

BV marine and offshore senior vice-president and CEO for North Asia and China Alex Gregg-Smith said: “The transition to a greener shipping industry is critical.

“Carbon capture, utilisation and storage (CCUS) technology captured a total of 40 million tonnes of CO₂ in 2021 according to the International Energy Agency (IEA), notably in industrial projects on shore.”

In January, Brittany Ferries announced that BV had classified its new liquefied natural gas (LNG)-powered Salamanca cruise ferry.
