Lightering | DONJON-SMIT

Lightering

Lightering is undertaken to reduce a vessel's draft, and in emergency conditions expertise is critical in ship-to-ship lightering.  Following international protocols and procedures, experienced Donjon-SMIT salvage teams execute carefully engineered lightering plans safely and efficiently, using purpose-built Donjon-SMIT equipment, fendering, diesel hydraulic-driven pumps, and portable inert gas generators.  Donjon-SMIT’s in-house salvage engineering capabilities allow emergency lightering operations to be conducted within the broader scope of vessel stability and hull strength considerations.

Off the coast of Western Unalaska Island, a salvage team inspected the casualty and safely removed the oil.

‘Selendang Ayu’

The Malaysian flagged 225 metres long cargo vessel suffered a main engine breakdown, drifted without power, grounded and eventually broke in two off the coast of Western Unalaska Island.  A salvage team was mobilized to inspect the casualty.  A complicated operation commenced to pump the oil from the vessel’s various compartments into tank containers which were placed on the deck of the vessel by helicopters. Each container was filled with 2.5 tonnes of recovered oil and then transported back to the shore by the helicopters for further handling.  An extra complication was the extreme weather situation, but the operation was successfully completed and approximately 1600 tonnes of intermediate fuel and diesel oil were recovered.
