Jeff has nearly 40 years of bunker buying experience in marine fuels, working as both a bunker broker and bunker trader. He first joined the relatively new bunker buying section ay Davies and Newman Shipping Company in 1973, after which he joined the fledgling company Bunkerfuels UK in 1984.

In 2001, Bunkerfuels Group was incorporated into the leading global bunker company World Fuel Services, whose other main company at that time was Trans-Tec Services. Both companies amalgamated some time later. Jeff remained here until his retirement in 2012, latterly working exclusively as an in-house bunker buyer for the diverse portfolio of various world-wide bunkering companies World Fuel Services owns.
