Highly exposed to the public and often operating in environmentally sensitive areas, the cruise industry is embracing cleaner fuels and alternative power systems to reduce emissions and its environmental footprint.

In line with the newly adopted strategy laid out in 2018 by IMO, fleets are moving toward LNG as fuel. It enables compliance with the most stringent IMO emission limits for nitrogen oxides (NOx) and sulfur oxides (SOx) without additional exhaust gas treatment. It provides a first step towards lower greenhouse gas emissions and can serve as a suitable transition fuel before a future move to carbon-neutral and carbon-free fuels.

Bureau Veritas is a leader for the classification of LNG fueled ships and LNG bunker vessels, running the gamut from large cruise ships to expedition cruise ships and RoPax ferries. We can provide in-depth technical support concerning gas containment technology, propulsion system design, LNG bunkering, and safety systems and training. Relevant class notations include additional service features like gasfuel and dualfuel, as well as the GAS-PREPARED notation.

Batteries—combined with a direct current (DC) electrical grid that allows for variable speed engines—are another form of propulsion on the rise, particularly for ships with large variations in power demand. Batteries can provide optimum energy efficiency and (temporary) zero-emission operation. Electric-hybrid power systems have been successfully trialed on ferries and could also prove capable for cruise vessels.

Bureau Veritas rules include dedicated BATTERY SYSTEM class notations for the safe installation and use of batteries on board and the ELECTRIC-HYBRID notation, which covers power management, power backup and zero emission modes. A new ELECTRIC-HYBRID PREPARED notation that prepares ships for future installation of batteries is currently under development.

French luxury cruise operator PONANT has ordered the world’s first dual fuel electric-hybrid expedition cruise ship from VARD Søviknes for delivery in 2021. Classed by Bureau Veritas, this highly advanced vessel combines clean fuels and electric power storage. Its advanced battery system is expected to set a new benchmark in sustainability in the cruise industry. Bureau Veritas will continue engaging with forward-thinking industry partners to develop the technology and regulatory framework for low- and zero- carbon fuels and advanced power systems.
