DNV GL Classification society has updated its bulk cargo liquefaction guidelines. Originally published in 2015, the revised guidelines are based on feedback from readers and practical experiences that have arisen historically. The guidelines focus on design and operation of vessels with bulk cargoes that may liquefy.
Specifically, the revised guidelines provide additional material to better describe precautions to be followed during voyages or even the steps to be taken in the possibility of cargo liquefaction.
According to DNV GL, two new paragraphs have been added: 5.8 and 5.9. In addition, parts 4 and 6 have been updated to include the latest developments, including DNV GL’s new class notation BCLIQ. We welcome your feedback on these new revisions.
Concerning the BCLIQ notation was launched in 2018, and reassures that a vessel is constructed to eliminate the free-surface effect, for example by featuring wide wing tanks and reinforced structural focus areas on the cargo hold side walls, and is consequently able to carry cargoes with a moisture content exceeding the transportable moisture limit (TML).
In addition, the notation confirms compliance with the SCCS (specially constructed cargo ships) requirements of the International Maritime Solid Bulk Cargoes (IMSBC) Code and enhances the ship’s loading flexibility, efficiency and safety.
Morten Løvstad, Global Business Director of Bulk Carriers at DNV GL said, “Cargo liquefaction is the number one safety issue for bulk carriers … The first guideline was very well received and by updating and expanding it, alongside our new BCLIQ class notation, we hope we can keep the industry’s focus on this critical safety issue.”
