There can be few lonelier places in the world than the deck of a burning oil tanker in the Red Sea with help hours away.

That was the position of the captain and the predominantly Indian crew of the 110,000-dwt Marlin Luanda (built 2018) in January after it was struck by a Houthi missile.

For four-and-a-half hours they tackled the blaze until trained firefighters from the Indian Navy turned up to end the crisis.
