Soon after anchoring the tug Gulf Spray arrived with a barge and attendant motor boat, and began pumping off some slops or waste. Another workboat, possibly with divers, also appeared in the area.
The ship was built by STX Jinhae Shipyard in Jinhae, South Korea in 2003, and is of typical handysize product tanker dimensions and measures 29,998 grt, 46,135 dwt. It is operated by Liquimar Tankers of Athens, and flies the Greek flag.
As with most Greek ships, it displays its name in English on the bow, but in Greek on the stern. Regrettably Blogger doesn't have a Greek font, but I have placed the Greek characters in the photo. The name Nefeli seems to derive from the ancient Greek mythology, where Nephele, was a cloud nymph.
