An ageing FSO laid-up off Yemen has been described as a "floating bomb" by environmentalists.
The 407,000-dwt Safer (built 1976), owned by Yemen's Safer E&P Operation Company, is anchored off Ras Isa.
Built in Japan, the single-huller may still contain around 1.14m barrels of crude.
It has not been operational since March 2015 when the region fell under the control of the Houthi rebels.
