Two separate explosions on VLCCs in recent weeks have raised concerns over tanker safety.
Last week, Shipping Corp of India's 316,217-dwt VLCC Desh Vaibhav (built 2005) suffered an explosion off the coast of Muscat, Oman.
The incident was severe enough for some of the crew to evacuate by lifeboat, with four jumping into the sea. Two members were flown to hospital, and all of the crew has now been accounted for.
