SSPL has given assurance to the district administration that the oil will be completely removed from the ship safely without any pollution within 36 days. The assistant salvage master of the company Wan Yet Fong made a presentation before the district administration, Port and Coast Guard authorities on the salvage operations at the Deputy Commissioner’s Office.
Briefing about the operations, Fong said that the oil will be extracted completely from the vessel without any leakage using hot tap system unit. “The salvage operation will be carried out in three major phases - mobilisation, execution and demobilisation.
Entire operation will be carried out by pumping out oil from all accessible bunkers through FOT vents. A combination of air driven and hydraulic driven pumps will be used depending on the viscosity of the bunkers, he explained.
Fong said that the hot tap system methodology is being used based on the condition of the wreck as it was last inspected by SMIT on December 1, 2 and 3. In the mobilisation phase, the craft (Hako Esteem), bunker barge (MOB Gazraaj), tug, hot tap system unit, diving equipment, pumping equipment, oil pollution control boat and personnel will be mobilised.
The execution phase involves various stages including offshore preparations, positioning moored craft, deploying of oil booms, cutting of vent heads (hot tapping), pumping oil from 16 bunker tanks and controlling pollution, he added.
Oil booms, oil skimmers and oil dispersant will be used to check the possible oil spill and pollution as part of the oil spill contingency plan. In the demobilisation phase, craft, equipment and personnel will be demobilised once the P&I Club representatives are satisfied with the oil removal. The demobilisation process will take another 12 days, Fong said.
