Norwegian shipowner Gjert Wilhelmsen has died at the age of 91.

Wilhelmsen ran shipping company Awilhelmsen with his brother Arne, after the company was founded by his father Anders in 1939.

Beginning in the late 1960s, the Wilhelmsen Brothers developed Royal Caribbean Cruises into what became the world's second largest cruiseship owner.

In 1988, A Wilhelmsen bought out its partners Gotaas-Larsen and IM Skaugen to prevent RCCL being purchased by rival Carnival.
