Multidisciplinary Digital Publishing Institute (MDPI) recently published a report focusing on the environmental benefits of fully battery powered ships when compared to marine diesel vessels.
RMI issued a marine safety advisory citing recent cases where ships have lost propulsion while in areas of high-density traffic or narrow waterways in China. Local PSC authorities have increasingly been concerned of similar incidents.
The technology group Wärtsilä along with the Norwegian company Aasen Shipping, came in an agreement for the construction and supply of the world’s first hybrid powered self-discharging bulk carrier. Namely, Wärtsilä will provide its design and supply hybrid systems for the vessels.
In a statement, Wärtsilä highlights that it has been a stellar year for its shaft generators, generating power for a ship’s auxiliary systems from its main engines, which can also be used to reduce shipping emissions. Michael Kranz, Manager, Shaft Generator Systems & Cargo, overseeing a department of eight engineers at Wärtsilä’s Marine Electrical Systems highlighted that “last week, we reached 500 units sold, an incredible milestone. In the same week, we sold a comprehensive (holistic) hybrid system to a series of hybrid RoRo vessels. After a relatively slow start to the year, we are now seeing a big increase in these systems being specified by owners interested in reducing emissions and fuel costs.”
France-based Neoline has concluded to the shipyard that will construct its first two sail-powered RoRo cargo ships to operate between France and US from 2021. Namely, chose France-based Neopolia to build the vessels. At first, the vessels will be operating on a pilot route, linking Saint-Nazaire, France with the US East Coast and Saint-Pierre & Miquelon off the coast of Newfoundland.
Carnival Cruise Line announced that Netherlands-based Boskalis will deploy a transport vessel as a first of its kind ‘floating dry dock’ facility to complete the repairs to Carnival Vista’s two azipods, the ship’s main propulsion system.
The Motorship Propulsion & Future Fuels 2018 conference was launched on November 14, focusing on fuels and propulsion technologies. The conference highlighted what needs to be done in order to meet the 2020 global sulphur cap goals, as well as IMO’s greenhouse gas emission reduction targets.
The Transportation Safety Board of Canada released its investigation report into the collision of the dredger FRPD 309 with the loaded barge Evco 60, on 5 December 2017, in the Fraser River, after it lost its propulsion due to a blackout. The FRPD 309 sustained damage to the shell plating and forepeak tank forward of the collision bulkhead.
As the world is changing, technologies that were the absolute norm, are now becoming old-fashioned. Up until now, ships have been sailing using fuels. However, it seems that electric vessels are gaining momentum, with many countries considering them as the future.
On the sidelines of SMM trade fair in Hamburg, Thordon Bearings published a study highlighting the commercial and environmental benefits of seawater-lubricated propeller shaft bearing arrangements. The study was carried out in response to the increase in oil EAL lubricated sterntube bearing failures.
