For ocean-going vessels such as fishing boats, time spent at port is generally time spent unprofitably. They can only make money out at sea, where the fish are. However, all ships have to come home to port occasionally for refueling and to land their catch. With a ship’s fuel making up a major part of its running costs, shipowners need to rely on a refueling partner that can provide reliable supplies at competitive prices. This is the mission of Oliehandel – Klaas de Boer B.V., which, as an independent supplier of heavy fuel, gas oil and lubricants, performs physical deliveries to clients across the Netherlands.
