The first of three ethane-fueled engines has been delivered for a trio of ships on order for Germany’s Hartmann Reederei on order at China’s Sinopacific Shipbuilding. They will be pioneers for ethane fueling, believes René Sejer Laursen, promotion manager at MAN Diesel & Turbo.

The ships will each carry 35,000m3 of the gas so have an obvious source of fuel, but Mr Laursen has a bigger vision: “we see potential for all ships to use ethane gas in the future,” he said during a presentation about the company’s multi-fuel engines during the Danish Maritime Days in October.

Britannia P&I Club has reported a recent case where a cargo of pressure boiler parts was physically damaged during transportation in moderately heavy weather en route from Hong Kong to Houston, supposedly due to poor packaging.

The ship encountered high seas and winds of Beaufort scale 9. The master had adjusted speed and course so as to minimise rolling and pitching but despite his actions, inspections carried out by the master in the cargo holds revealed the cargo stowed in hold no. 2 had been damaged.

DNV GL has noticed an increase in the number of reported incidents involving aft propeller shaft bearing damage. With this in mind, they have issued technical advice with their opinion on the contributing factors to this damage. Much of the damage in the reported cases has developed within a short period of time, typically a few minutes to an hour.

Typical damages observed and their consequences
The observed trend is not specific to a vessel type – rather, it reflects operation of the affected vessels in areas with limitations on the draft of the vessel or loading conditions, without suitable precautionary measures to limit the RPM/power of the engine.
