A growing fleet of laden crude carriers is gathering off the ports of Qingdao and Rizhao in Shandong province waiting to discharge.

At least 20 tankers from aframax to VLCC, 16 years old or more, have taken up residence there, several for periods up to two months.

The elderly ships constitute a significant fraction of what some tanker owners have called the “rogue fleet” of cast-off vessels.
