DNV has been selected to lead an ammonia bunkering safety study by the Global Centre for Maritime Decarbonisation (GCMD) in Singapore, according to the company's release.
The pioneering study aims to define a robust set of safety guidelines and operational envelopes that will establish the basis of a regulatory sandbox for ammonia bunkering trials at two local sites.
To that end, DNV will team up with Singapore’s leading infrastructure developer Surbana Jurong and the Singapore Maritime Academy (SMA). DNV’s work scope will comprise ammonia demand forecasting, bunkering site recommendations, the development of conceptual designs of bunkering modes like truck to ship or ship to ship, HAZID/HAZOP/QRA studies, as well as drafting of technical and operational guidelines.
While ammonia is one the most promising fuels to decarbonize shipping, DNV research shows that a number of safety gaps hold the potential to disrupt the speed and success of the transition.
In response to the growing industry interest for ammonia fueled and ammonia ready ship designs, DNV has undertaken many trailblazing projects in the development of ammonia as a viable future marine fuel.
DNV’s “Fuel ready” notation was launched as an industry first in April 2021 by Höegh Autoliners in their new series of car carriers. The notation verifies that a vessel complies with the safety and operational requirements for future ammonia fueled operations, and that the main engine can be converted or operate on the fuel.
For shipowners looking to move towards a full zero-carbon fuel option with their next newbuilding, DNV’s new “Gas fuelled ammonia” rules provide a practical path. Further adding to this work, DNV has awarded several Approvals in Principle for ammonia fuelled ship designs, while also cooperating with engine maker MAN Energy Solutions on the safe development of a 2-stroke ammonia engine intended to be market-ready in 2024.
According to its recent Maritime Forecast to 2050, DNV expects there will be demonstration projects for onboard use of ammonia by 2025, paving the way for zero-carbon ships ready for commercial use by 2030. While the future fuel mix will be broad, DNV predicts that both ammonia and bio-based methanol are the most promising carbon-neutral fuels in the long run.
