Sadly, there is extremely limited information on the man commemorated no this gravestone.
Nier Mohammed Kaloo (or, alternatively, Mur Muhammed Kaloo), was born in around 1890. He joined the Royal Navy and, by the end of the war at the latest, he had been transferred to the Royal Auxiliary Fleet as a Fireman.
His ship, the SS Petroleum, acted as a tanker for other naval vessels. In the immediate aftermath of the war, she travelled between Portsmouth and Copenhagen, but soon took on longer trips, to Hong Kong and the Far East.
It was after returning from Singapore in the first half of 1921 that Fireman Kaloo died, although the cause of his passing is lost to time. He was 31 years old. The ship having moored at the Naval Dockyard in Chatham, Kent, he was laid to rest in the Woodlands Cemetery in nearby Gillingham.
