The threat of "significant" spillage from a bulk carrier stranded off Cape Town has passed as most of its fuel has been removed, a committee handling the matter said on Sunday.

About 500 tonnes of the 660 tonnes of fuel on board the Turkish vessel, Seli 1, had been pumped to another vessel, read a statement by the joint operations committee, headed by the SA Maritime Safety Authority.

She ran aground on 7 September at Table View beach.

"[The] remaining oil onboard is residual in nature and located in small quantities in fuel tanks, the engine room and topside tanks. Salvors are moving pumping equipment from tank to tank in an effort to access these remaining pockets of oil."

As a precautionary measure, an oil pollution boom was still in place at Milnerton Lagoon and response teams remained on standby.

"The pollution patrol aircraft Kuswag 9 continues to overfly the casualty daily and has reported no oil in the vicinity of the casualty today [Sunday]."
