The former high-profile Norwegian shipbroker Ole Jakob Libaek, who helped pioneer ship types such as aframaxes and OBOs, has died at the age of 83.

He suffered a heart attack during a visit to his mountain cabin.

Libaek started his career at shipbroker Conrad Boe, followed by stints at broking houses Davies & Newman and Seabrokers. Starting in 1966, he worked at shipowner Stolt-Nielsen, where he eventually became responsible for broking activities.
