BV AIP for boxship jumboisation and dual-fuel retrofit

Bureau Veritas (BV) has issued an AIP for a new retrofit concept combing LNG fuel conversion and vessel jumboisation for a very large containership.

The design concept has been jointly developed by Cosco Shipping Heavy Industry (Zhoushan), GTT and Alwena Shipping.

GTT carried out the LNG Mark III membrane tank design while its integration into the ship was designed and validated by Alwena Shipping. Cosco Shipping Heavy Industry (Zhoushan) validated the operational aspects of the project, including the work sequence, planning and workforce resources.

The increase in length of the ship or jumboisation, combined with the LNG conversion of the propulsion and electrical generation systems enables a reduction in the operating costs of the ship, which limits the financial impact of the immobilisation period required for the retrofit operation.

In comparison with a conventional fuel-powered container ship, the converted vessel reduces CO2 emissions by around 23% over an 83-day Europe-Asia return trip.

The joint developed project between GTT, Alwena Shipping and CHI Zhoushan supports the technical, operational and commercial design of the conversion and jumboisation operation, while also proposing a competitive industrial plan. The result of this joint work shows the way to contribute to decarbonise part of the containership fleet currently in operation.
