DNV GL, Classification society, launched its updated bulk cargo liquefaction guideline at the Nor-Shipping trade fair this week. The Guidelines were firstly published in October 2015; The revised Guidelines are based on feedback from readers and practical experiences that resulted in the past. Thus, they focus on design and operation of vessels with bulk cargoes that may liquefy, and has already contributed to raise the awareness of the risks of cargo liquefaction on ships.
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 comments
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.
