Authorities remain on call, but the X-Press Pearl wreck remains stable, the ship's operator said on Friday.
X-Press Feeders said there were still "no signs of debris and no reports of fuel oil pollution" from the 2,743-teu, 2021-built boxship as of Friday night.
"Salvors were able to retrieve the anchor and remain on scene to deal with any possible debris supported by the Sri Lankan Navy and the Indian Coast Guard, who have oil spill response capabilities on standby," the Singaporean company said, reiterating its statement from Thursday.
