Classification society ABS on Thursday (6 January) launched the Guidance Notes on Strength Assessment of Independent Type C Tanks to prepare for the increased use of Type C tanks on shipping’s decarbonisation.
Alternative fuels will play an important role in the decarbonisation of shipping, increasing the popularity of Type C tank designs for vessels, forecasts ABS.
Independent Type C liquefied gas cargo tanks, used in gas carriers, bunkers, and barges, can be used to carry LNG, LPG, ammonia, and hydrogen in a liquid state and are seen as a promising solution for transporting these gases.
Type C gas fuel tanks, such as vacuum-insulated Type C tanks with double shells, allow for the same flexibility in fuel options when powering vessels and is the most popular design for a gas fuel containment system.
“As we introduce new designs into shipping, it is important to maintain a focus on safety,” states ABS.
“Therefore, ABS has developed Guidance Notes on Strength Assessment of Independent Type C Tanks which provides procedures for determining design loads on the Type C tanks and performing the strength evaluation of the tank and supporting structures.”

ADNOC L&S, Gulf Energy Maritime, Cockett Marine Oil, Mideast/Bahri Ship Management and VPS experts present their views on biofuel bunker hurdles at the VPS Biofuels Seminar in Dubai on 16 March.
‘Bunker barges operate in very local areas so these vessels call at port very often which means it will be a good fit for women with families,’ states Elpi Petraki, President of WISTA International.
“Our Singapore branch is under preparation and is expected to start business at the republic before June 2023,” Managing Director Darcy Wong tells bunkering publication Manifold Times in an interview.
Development to supply B35 biodiesel blend officially takes effect on 1 February; local bunker suppliers will be able to deliver updated spec within March onwards, once current stocks of B30 avails run out.
VPS, Global Centre for Maritime Decarbonisation, Wilhelmsen Ship Management, and INTERTANKO executives offered a multitude of perspectives to 73 attendees during the VPS Biofuels Seminar, reports Manifold Times.
