ClassNK-NAPA software installed on LNG carriers

NAPA, the maritime software house, and ClassNK said that they have begun installation of new performance monitoring software on an Asian LNG carrier’s fleet.

The new ClassNK-NAPA GREEN system has been installed to work in conjunction with NAPA’s Gas Tanker Loading Computer, to provide a full 360° view of the operation of these vessels, NAPA said in a statement.

LNG carriers have a unique operational profile, complicated by the ability to use wastage, or boil-off, from the cargo as fuel for the transit. This puts vessel crews in the centre of a delicate balance between the interests of the ship operator and the cargo owner when reporting performance and efficiency.

To help square this circle, ClassNK and NAPA have developed a specialist ClassNK-NAPA GREEN solution for LNG carriers that ensures transparent and accurate measurement of performance and efficiency, including measurement of boil-off. The measurements are easy to interpret onboard by crew, as well as being remotely and automatically shared with shore-based reporting systems – delivering vital data that can be passed between owner, operator and chartering cargo owner.

As with other ClassNK-NAPA GREEN solutions, the LNG-specific software also provides effective and actionable analytics around fuel consumption, trim, route, speed and operational efficiency. Amid fluctuating bunker fuel prices, the software optimises operations to fit the profile that makes the most commercial sense for all stakeholders. However, unlike standard ClassNK-NAPA GREEN systems, it is tailored to take into account the various fuels used by LNG Carriers – meaning it can adapt to provide the most accurate operational analysis depending on the fuel used.
