The announcement by Ambrey on Thursday came a day after Oman’s environmental authority confirmed that oil from the Caroline Bezengi had reached beaches along the sultanate’s central coast. The tanker, a suspected member of Russia’s shadow fleet used to transport sanctioned Russian oil, has been leaking crude into waters near the Hallaniyat archipelago since June, when the ship’s crew reported an unidentified explosion. Ambrey said it was working with Omani authorities and that its services had been engaged as part of a “significant international response” that included salvage vessels, aircraft and specialist personnel. Apart from Oman and an unnamed “leading international oil spill response company”, Ambrey did not elaborate on which other countries or firms were involved in the effort to salvage the vessel, which has flown the flags of states including Cameroon, Palau and Liberia. The International Maritime Organization (IMO) – the United Nations maritime agency – said on Thursday that it was “closely monitoring” the situation and would “continue to support ongoing efforts”, without providing further details. The International Oil Pollution Compensation Funds, a pair of intergovernmental organisations established to provide compensation for oil pollution, said it would not be involved in the cleanup operation after determining that the incident likely resulted from an act of war. Ambrey, based in Hereford in the United Kingdom, said it expected salvage vessels to reach the Caroline Bezengi soon and that specialist personnel had already boarded the vessel to begin stabilising its cargo. Ed Wollaston, director of global response at Ambrey, said the “extremely challenging situation” had been complicated by adverse weather from the annual Khareef monsoon. “However, we have deployed the leading experts in each aspect of the response and have mobilised the appropriate supporting equipment, aircraft and vessels,” Wollaston said in a statement. “We are working around the clock to mitigate the environmental impact of the situation.” The oil spill has expanded dramatically in size over the past week, according to analyses of satellite imagery, raising fears for coastlines and ecosystems in the region, including a marine reserve established last year off the Hallaniyat archipelago. Environmental NGO Greenpeace said on Thursday that, based on satellite imagery, the spill had grown from 45 square kilometres (17sq miles) in late July to about 1,300sq kilometres (502sq miles) as of Wednesday. Omani authorities as recently as Monday estimated the size of the spill at approximately 400sq kilometres (154sq miles). Hanen Keskes, Greenpeace’s head of campaigns for the MENA region, said the circumstances of the spill made it “especially challenging” to respond to. “Given the scale of this – a damaged tanker in a remote location, during monsoon season, with no clear owner or verified insurer to compel a rapid response – this is a case where international assistance should be mobilised urgently,” Keskes told Al Jazeera. “Capabilities like specialised salvage equipment and expertise can exceed what any one country has on hand, and every day of delay allows more oil to disperse.” Najmedin Meshkati, an expert in oil spills and a professor of civil and environmental engineering at the University of Southern California, said that authorities should have moved faster to contain the spill. “That two-month interval was the response window, and it closed. In spill response, source control on day three is worth many multiples of source control on day 60,” Meshkati told Al Jazeera. Meshkati acknowledged, however, that Omani authorities had been dealt a difficult situation. “It was handed an orphaned wreck with no responsive owner, no verifiable insurer, no functioning flag state, and a compensation regime containing a war exclusion that may void it entirely,” Meshkati said. “No mid-sized maritime administration on earth is resourced for that. But that is precisely the argument for escalating harder and earlier.” Damilola S Olawuyi, a professor of energy and environmental law at Hamad Bin Khalifa University in Qatar, said the spill highlighted the need for stronger international mechanisms to hold polluters accountable. “The obligation of the entity responsible for pollution to pay for the cost of cleanup and remediation, ie, the polluter pays principle, has for long been a bedrock of international law,” Olawuyi told Al Jazeera. “However, in an era of increasing geopolitical realignments, identifying the responsible polluter has become complex, therefore complicating effective risk reduction, response and remediation measures,” he said.
