A team of firms has actually collaborated to establish a much better understanding of the useful facts associated with utilizing ammonia as a gas for ships.
Ammonia is just one of a variety of alternatives to be an aquatic gas of the future. One of the crucial elements in the team’s method is to check out the wider range of effects for several ship kinds and also various functional demands, consisting of bunkering and also port procedures.
A very first step has actually been to hold a risk recognition workshop (HAZID) to comprehend the dangers entailed with utilizing ammonia as an aquatic gas.

Panos Koutsourakis, Global Technology Leader for Sustainable Shipping at Bureau Veritas describes why ammonia is being thought about as an aquatic gas: ‘Ammonia is a carrier for hydrogen which can be generated from renewable energy and ammonia storage and transportation can, in principle, be managed with established technologies.’
‘But ammonia is both toxic and corrosive. We need to understand, if and how, the associated risks can be managed to merit further practical and commercial development – especially confirming the potential for stable combustion and NOx emissions. Furthermore, potential availability is not yet assured. Sufficient availability of “green” ammonia would require the scalable development of “Power-to-X” technologies to provide the volumes necessary for shipping.’
In contrast with traditional hefty gas oils, ammonia is much less power thick, can be melted at -33 ° C, and also kept at air pressure for usage as an aquatic gas.
The team of individuals is concentrated on the safety and security problems that require to be attended to. Currently, elements of utilizing ammonia are not clearly covered by the existing regulative structure– significantly IMO’s International Code of Safety for Ship Using Gases or Other Low- flashpoint Fuels (the IGF Code), and also call for details interest. The team will certainly execute in-depth threat research studies to evaluate the technological expediency and also details safety and security dangers of ammonia sustained ships for considering its prospective as a secure gas for the decarbonization of delivery. Each getting involved company is supplying its appropriate proficiency to the job in order to examine all prospective dangers.
The HAZID workshop held at MALE’s workplaces in Copenhagen was the initial of these research studies.
Commenting, BV’s Diane Ruf, Head of Section, Risk, Reliability & & Maintenance, at Bureau Veritas Solutions, Marine &Offshore, claimed,‘The workshop was carried out to identify the safety and operational hazards associated with the use of ammonia as fuel for propulsion engine on board a VLCC. The study led to the identification of practical safeguards and recommendations which should be considered in order to lower the risks to As Low as Reasonably Practicable (ALARP). It covered: NH3 storage space and bunker stations, NH3 Fuel Treatment Room and HP Fuel Pump Room (combined), Engine Room (Gas-safe), Vent/Safety system lines and Vent Mast and ship’ s procedures.’
Next actions are being thought about, yet will certainly consist of attending to functional risks and also looking even more deeply at theoretical styles based upon various vessel kinds.
