DNV’s Onboard Carbon Capture and Storage Guidelines Pave the Way for Safer and Greener Shipping

(IN BRIEF) DNV, a prominent maritime classification company, has released new guidelines for the safe installation of onboard carbon capture and storage (OCCS) systems on ships. These guidelines come at a critical time when the shipping industry faces increasing pressure to adopt emission-reduction technologies as part of the ongoing maritime energy transition. OCCS systems are seen as a key solution for reducing greenhouse gas emissions on trading vessels where alternative fuels may not be feasible. The guidelines cover all aspects of safe installation, from exhaust pre-treatment to CO2 storage and transfer systems, and are intended for use by various stakeholders, including ship designers, builders, OCCS system manufacturers, and ship owners. It’s important to note that while these guidelines are based on DNV classification requirements, additional requirements may be imposed by flag-state administrations. Currently, there are no statutory regulations addressing the safety implications of using OCCS systems on ships.

(PRESS RELEASE) BÆRUM, 9-Oct-2023 — /EuropaWire/ — DNV, a leading provider of software solutions for the maritime industry, and a global leader in maritime classification, has unveiled a set of groundbreaking guidelines tailored to ensure the safe installation of onboard carbon capture and storage (OCCS) systems on ships. These guidelines arrive at a crucial time when the shipping industry faces mounting pressure to develop effective emission-reduction technologies as part of the ongoing maritime energy transition.

To fulfill international, regional, and national emissions targets, diverse approaches for curbing greenhouse gas (GHG) emissions are essential. Post-combustion OCCS systems, implemented on trading vessels, are poised to play a significant role in the future of emissions reduction, particularly on ships where the use of alternative fuels may not be feasible.

DNV’s newly published guidelines have been crafted to cater to stakeholders throughout the value chain. This includes ship designers, builders, OCCS system manufacturers, and ship owners. The guidelines apply equally to newbuilds and retrofitting projects, encompassing every facet of safe installation. Key areas covered include exhaust pre-treatment, chemical/amines-based absorption, after-treatment systems, liquefaction processes, CO2 storage, and transfer systems.

“Our new guidelines for onboard OCCS systems aim to support the industry as it faces strict requirements for emissions reduction. A focus on safety is crucial for new technology and must be prioritised as the industry looks to adopt sustainable fuels and CCS installations,” said Chara Georgopoulou Head of Maritime R&D and Advisory Greece, Senior Research Engineer II, Onboard CCS Manager. “While CCS technology is already known in land-based industry, its application on board ships is relatively unproven. Our guidelines provide a framework for installation, offering support for stakeholders in the industry, while contributing to reducing emissions and driving the maritime industry towards a more sustainable future.”

It is important to note that while these guidelines are rooted in DNV classification requirements, relevant flag-state administrations may impose additional technical or regulatory requirements. Presently, there are no statutory regulations specifically addressing the safety implications of employing OCCS systems on ships. Additionally, DNV’s guidelines extend to alternative carbon capture solutions, encompassing physical absorption and cryogenic methods.

DNV’s pioneering guidelines were officially published in September and are readily accessible here.
