MARIC’s five ‘ammonia-fueled’ vessels receive AiP certificates

On September 3, one of the most influential exhibitions in the world, the SMM trade fair in Hamburg, Germany, opened. Five high-quality ship models, such as 150,000 cbm Liquid Ammonia Carrier (ULAC) and 16,000 TEU Ammonia-fueled Powered Containership, independently researched and designed by Marine Design and Research Institute of China (MARIC), a subsidiary of China Shipbuilding Corporation (CSGC), were respectively granted Approval-in-Principle (AiP) certificates issued by internationally renowned classification societies.

The 150,000 cbm ULAC is a new generation of very large liquid ammonia carrier independently developed by MARIC, which has obtained AiP certificate issued by DNV. It is 278 meters in overall length and 44 meters in beam, with A type independent liquid cargo tanks and a cargo volume of 150,000 cubic meters. Equipped with an LPG dual-fuel main engine and reserved for the use of ammonia fuel, the ULAC can meet the most stringent emission requirements while maintaining optimum economy. The ULAC has good rapidity indicators and, in addition, it meets the latest cybersecurity requirements that have come into force.

HERCULES series 16,000 TEU ammonia-fueled powered containership was granted AiP certificate by China Classification Society (CCS). Equipped with an independent B type ammonia tank with a capacity of 16,000 cubic meters, the ship’s range can support one-way voyages on the Asia-Europe route and other world mainstream routes. By using ammonia as a marine fuel and combining with exhaust gas treatment technology, it can significantly reduce emissions of sulfur oxides, nitrogen oxides, and achieve zero carbon emissions.

The 20,000 cbm ammonia fuel bunkering vessel has been awarded AiP certificate by CCS and Lloyd’s Register (LR). With a length of 157.9 meters and a beam of 25 meters, the vessel is suitable for ammonia bunkering operations in major ports around the world. The vessel adopts two single cylinder C type cargo tanks, which has the advantages of smaller boil off rate (BOR), more flexible BOG management, higher capacity utilization, less DOME quantity, higher reliability and simpler operation. With three manifold areas and two folding jib cranes, it can match matched to a wider range of different scales of refueled vessels.

Equipped with ammonia leakage detection, ammonia capture, NOx and N2O SCR system etc., it is an ammonia fuel bunkering vessel with large single refueling capacity, good vessel matching, good maneuverability, high reliability, excellent economy and green environment protection.

The 82K ammonia-fueled bulk carrier has received an AiP certificate from Bureau Veritas (BV). It is the largest Kamsarmax bulk carrier powered by ammonia fuel with single propeller, which can be operated for global voyage. The bulk carrier is equipped with 2 C-tank ammonia fuel tanks with a total fuel tank volume of about 3200 cubic meters.

The economic speed range in gas mode is up to 19,000 nautical miles, with a larger fuel tank is retained, in fuel mode it has a range of more than 23,000 nautical miles, with an open scrubber tower as an alternative to reduce fuel costs. To improve fuel economy, the bulk carrier is installed with energy-saving devices, variable frequency pumps, fans and LED lights; In addition, bulk carrier integrates intelligent systems that can provide assistance in route planning, energy consumption monitoring and ammonia fuel system monitoring.

The 162,000 dwt ammonia-fueled largest Suezmax product tanker has received an AiP certificate from the American Bureau of Shipping (ABS). This product tanker has a length of 274 meters, a beam of 50 meters and a structural draft of 17.15 meters. It is powered by single engine and single propeller, with ammonia dual-fuel main engine to meet the requirement of unlimited navigation area.

The ammonia fuel tanks are semi-cooled and semi-pressurized of the product tanker, with two C type independent liquid tanks of carbon manganese steel on the main deck, each with a capacity of about 3,000 cubic meters. It has a range of up to 12,000 nautical miles. In addition, it features low fuel consumption and high cargo carrying capacity with a variety of energy-saving measures.

Focusing on “green, intelligent and low-carbon” and digital technology, MARIC continues to carry out key technological research on green ships, intelligent ships, polar ships, etc., and it has successively launched a full series of solutions for dual-fuel containerships, bulk carriers, tankers, gas carriers, etc., as well as continued to optimize and update .
