Chennai, Sep 4 : The Indian Coast Guard is working on a multi-pronged strategy to prevent an oil spill from the blazing very large crude carrier (VLCC) 'New Diamond', laden with about 300,000 tonnes of crude oil, and also for towing and anchoring the vessel, an official said on Friday. A Coast Guard official said the massive oil tanker's towing and anchoring facilities are still in a working condition. The vessel, chartered by Indian Oil Corporation (IOC), is on fire since Thursday morning, about 37 nautical miles off the Sri Lankan coast and is in its Exclusive Economic Zone. Two Coast Guard Dornier aircraft, with pollution response spray pods and oil spill dispersants, are being launched from Tuticorin to Mattalla as a preventive measure towards any oil spill contingency, the Coast Guard said. The aircraft will augment the Coast Guard and Sri Lankan Navy ships engaged in dousing the blaze. Coast Guard ship Sarang has also reached the spot and joined the fire fighting operations. According to the Coast Guard, its ships Sarang and Sujay with Pollution Response Equipment and a Chetak helicopter have been pressed into service. Further, two Coast Guard Fast Patrol Ships Ameya and Abheek have been deployed from Karaikal and Chennai, respectively, with 1,000 litres of Oil Spill Dispersant (OSD), Dry Chemical Powder (DCP) and others to augment pollution response efforts. Also, its Pollution Response Ship Samudra Pahredar is deployed specifically for any oil spill contingency. The Coast Guard's Pollution Response Teams and vessels are kept standby with embarkation plan of equipment at short notice. Meanwhile, New Diamond's Captain along with a Coast Guard officer and a sailor boarded the blazing oil tanker and assessed towing and anchoring facilities of the massive vessel. "The towing and anchoring facilities are in good condition for those activities. Where the vessel would be towed will be decided by the Central government," a Coast Guard official told IANS. He also said the cargo pumping facility is also intact and the cargo area has not been affected. According to him, the fire is on the vessel's port side and there is not much heat on the deck. The fire in the crew accommodation area has been put out. The Indian government has decided to deploy two emergency towing vessels to tow New Diamond. "No oil spill reported in the area. Two emergency towing vessels being deployed by GoI (Government of India) for #MTNewDiamond," the Coast Guard said. The Coast Guard also said a two-metre crack has been observed near the port aft portion of New Diamond, 10 metres above the waterline. "If the crack propagates, and there is every likelihood of that but cannot be predicted, then the ship's stability could be affected. A ship at a standstill is still subjected to tremendous stresses and could break and capsize," M. Kalayanaraman, Technical Editor, Riviera Maritime Media, told IANS. Kalyanaraman also said if the fire is still raging, it means availability of fuel for the blaze. Owing to the concerted joint action by the Coast Guard ships and the Lankan Navy, 22 crew from the oil tanker have been rescued while a search for a missing Filipino crew member is on. As per www.marinetraffic.com, the 20-year-old VLCC 'New Diamond' sailing under the Panama flag departed from Mina Al Ahmadi on August 23 and was headed to India's Paradip port. The oil tanker was expected to reach Paradip in Odisha on September 5 where the IOC has a large refinery. The Coast Guard said the Sri Lankan Navy had sought assistance to fight the fire and the explosion on board New Diamond. On the other hand, IOC officials were silent on the accident. According to reports, another oil products tanker Helen M, sailing under the Panama flag, had reached the location of New Diamond for rescue after receiving a distress message. Helen M was sailing from Mengaluru to Kakinada in Andhra Pradesh. /IANS
