Classification for hydrogen-fuelled tug


Classification for hydrogen-fuelled tug

ClassNK has added Japan’s first hydrogen-fuelled tug Ten-Oh to its register, built by Tsuneishi Shipbuilding Co., Ltd. This vessel was developed and built under the ‘Nippon Foundation Zero Emission Ships Project’, a grant program by The Nippon Foundation aimed at developing ships with zero CO2 emissions. Based on discussions among the parties involved during the planning stage of the vessel, ClassNK reviewed the safety requirements and countermeasures for hydrogen-fuelled ships by applying Part GF of its ‘Rules and Guidance for the Survey and Construction of Steel Ships’ etc. These reviews focused on issues such as preventing explosions caused by the high ignitability of hydrogen and mitigating the potential impacts of hydrogen fuel leakage on crew members and the environment.

ClassNK says that it will continuously support the safe operation of the vessel through surveys in service, and not only that, support industry’s effort toward decarbonisation through using the knowledge and experience gained from the surveys for keeping its guidelines up to date and contributing to establishment of the appropriate international standard.

Manyar smelter faces supply issues

Freeport Indonesia may be forced to suspend operations at its Manyar smelter at the end of October due to a lack of copper concentrate, according to local press reports. The news follows the mudslide at the Grasberg mine in September, which killed seven workers. Grasberg, which represents almost 3% of global copper mine production, has halted production and Freeport says that it may not return to pre-accident operating rates until 2027. Stocks of copper concentrate at Grasberg were estimated to be only sufficient to operate the Manyar smelter until the end of October. The $3.7 billion Manyar smelter only resumed operations in May after a fire broke out in October last year, damaging the plant.

Government to limit new nickel projects

The Indonesian government has moved to limit new licenses for nickel projects in an attempt to correct overdevelopment of the industry and the subsequent crash in global nickel prices. The permit restriction applies to new nickel processing companies that produce intermediate products, both with pyrometallurgical (RKEF) and hydrometallurgical (HPAL) technologies. Currently, Indonesia already has 54 nickel processing plants operating, 38 in the construction stage, and 45 are still under planning.

Paradeep plans additional phosphoric acid capacity

Paradeep Phosphates Ltd (PPL) has announced a $400 million capacity expansion program, following its October 13th merger with Mangalore Chemicals & Fertilizers Limited (MCFL). This company says that the move aims to strengthen PPL's market position and enhance its production capabilities. The investment will involve increasing granulation capacity by 1.0 million t/a at the Paradeep site, as well as an additional 250,000 t/a of phosphoric acid and 750,000 t/a of sulphuric acid capacity at the company’s new Mangalore site. The expansion is expected to be completed within three years, according to PPL, and is expected to ensure 100% backward integration for fertilizer production, reduce import dependency, and enhance operational capabilities and profitability. low-contaminant phosphate concentrate that allows for easy conversion into purified phosphoric acid. The company has spent over C$100 million advancing the project and has received funding and investment from the Quebec Government.

METI funds hydrogen for steel and ammonia production

As part of the Japanese government’s Green Transformation scheme, two hydrogen producers have been selected to receive subsidies for low-carbon production projects. Out of the overall $1 trillion GX scheme, $51 billion is earmarked for hydrogen and ammonia investments, with the bulk going towards a long-term programme that subsidises the increased production costs. The first two recipients are a Toyota Tshuho-led consortium (electrolytic hydrogen for steel), and Resonac (hydrogen from used plastics for ammonia). In the programme, production projects are required to have the support of a major hydrogen consumer – in Resonac’s case, this is Japanese chemicals giant Nippon Shokubai, who will offtake the ammonia produced from lower-carbon hydrogen.
