World’s first hybrid self-discharging bulk carriers

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.

Shaft generators help limit shipping emissions

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.”

Sail-powered cargo ships to operate between France and US

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.

Watch: Carnival Vista to be dry docked for azipod repairs

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.

Conference focuses on fuels and propulsion technologies

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.

Loss of propulsion leads dredger to collide with loaded barge

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.

Are electric vessels the future of shipping?

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.

Study: The true cost of oil-lubricated propeller shafts

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.

LNG carrier suffers loss propulsion off Papua New Guinea

The two-year old LNG carrier ‘CESI Gladstone’ will resume it route to China within this week, after it suffered loss of propulsion while underway from Australia on 22 June. The ship had just loaded a cargo at the Australia Pacific LNG plant, when it sustained a main engine outage resulting in a loss of propulsion,
