Wärtsilä’s recently developed and patented technology, known as Wärtsilä Ammonia Release Mitigation Systems (WARMS), has obtained Approval in Principle from DNV, a renowned classification society. This approval applies to the implementation of WARMS on ships using ammonia as fuel, denoted by DNV’s classification notations “gas fuelled ammonia” or “GF NH3” for gas tankers, as reported by Maritime Executive.

Reduction in emission of ammonia

Wärtsilä has developed an innovative system called Ammonia Release Mitigation Systems (WARMS) that addresses the risks associated with using ammonia as a future maritime fuel. Ammonia can be hazardous to health and the environment if not handled and stored properly. WARMS significantly reduces the emissions of ammonia, with levels below 30 parts per million (ppm) and often close to 0 ppm. DNV, a leading classification society, has awarded an Approval in Principle (AiP) to Wärtsilä for their WARMS solution. The Gas Fuelled Ammonia notation provided by DNV offers a practical pathway to realize ammonia as a zero-carbon fuel option. This recognition demonstrates Wärtsilä’s commitment to developing a solution that adheres to the most advanced technical rules in the maritime industry, ensuring safety remains a top priority.

Strict regulation for evolving standards

Wärtsilä has introduced WARMS, a system that complies with existing and anticipated regulations, ensuring future fuels’ safe and environmentally friendly use. Ole Fjeld, Product Line Manager at Wärtsilä, emphasises that as stricter regulations are expected, the system is designed to meet these evolving standards. WARMS enables accurate and continuous monitoring of emissions, incorporates staged and controlled combustion, minimizes energy consumption and waste, and has a compact footprint. By providing a green and safe alternative to venting pure ammonia or diluting it with air or hazardous water, WARMS contributes to Wärtsilä’s decarbonization efforts. Wärtsilä, with over 60 years of experience in developing solutions for ship protection and environmental sustainability, showcases its commitment to innovation and safety in the maritime industry.
