Schiffstechnik | Ship Technology » The environment must be protected, but this will require regulations to become progressively stricter. The quest to a green transport sector is causing a rising demand for low carbon and low emission engine technologies. Alternative power generation systems are being developed and replacing diesel engines, often implying a fuel switch – LNG, biofuel blends, methanol/ethanol – and ultimately hydrogen. In fact, the construction of the first ferry powered by hydrogen has recently started. Sooner than later we will see a further shift towards Li-ion and nextgeneration batteries. Methanol is also one of the possible alternatives to power fuel cell generation systems. The digitalization trend will probably be one of the major reasons for further regulatory development. Remote controlled or autonomous ships, e-certificates, single window will all need to be thoroughly regulated in order to ensure a high level of data protection and keep communications systems safe from cyber attacks. By implementing innovative technologies and smart policies to improve energy efficiency on ships, fuel Photo: RINA »For the time being, it will be more important to make sure that crews are able to manage, operate and maintain the new generation of ship« Paolo Moretti, Executive Vice President for Marine Strategic Development, RINA consumption and costs are significantly reduced. Saving fuel goes hand in hand with controlling emissions of greenhouse gases, therefore the share of newbuilds powered by alternative fuels is set to increase. The fuel choices made by shipowners depend on many factors. The type of ship, for example. Besides LNG and given the current situation of ships, ports, infrastructure and logistics, and given the type of ships and routes, the combination of scrubbers and batteries is also an option. Many shipowners are opting for the use of batteries: Grimaldis hybrid RoRo vessels, for delivery starting from 2020. The new vessels will be equipped with mega lithium batteries that are, until now, the world’s most powerful batteries ever to be installed on a ship. It is foreseeable that by 2025, probably 3/4 of the cruise ships on order could run on LNG. Autonomous/remote controlled ships, instead, will probably need some more time to reach the same share. In five years some operators might use not totally autonomous, but mainly remote-controlled ships in certain areas only. In the near future, most of the ships will still be manned. For the time being, it « will be more important to make sure that crews are able to manage, operate and maintain the new generation of ships, that heavily relies on data and software use.
