Marine fuel trading firm Eleven Energy has strengthened its Rotterdam team with the hire of a bunker trader.

Jorn Berkelaar joined the firm's Rotterdam office as of this month, the company announced in a LinkedIn post today.

"We are pleased to introduce our new colleague, Jorn, who will be joining our Rotterdam office from 1 September," the firm said.

"Jorn has a strong background in the international independent inspection, laboratory testing, and verification services sector, with experience supporting the global energy and petroleum industry."

"He also has several years of experience in an operational and commercial role within the European market."

Before joining Eleven Energy, Berkelaar worked for Minerva Bunkering as a commercial trading operator of bunkers in Rotterdam from January 2024 to April 2026. Earlier in his career, he spent more than eight years with Saybolt International in Rotterdam.

Rotterdam is one of the world's largest bunkering hubs, and the port regularly ranks among the biggest marine fuel delivery centers in Europe, making it a key location for bunker suppliers and traders serving shipping traffic in Northern Europe. The port's scale means hires in Rotterdam trading desks can affect firms' ability to compete for marine fuel volumes in the region.

Berkelaar's combined background in inspection and testing services and commercial bunker operations reflects a common career path in the marine fuels sector, where quality verification and quantity measurement are central concerns in physical bunker trading. Firms in this market have also been adapting to regulatory changes affecting marine fuels, including the International Maritime Organization's 2020 limit on sulphur in ship fuel and the continued rollout of FuelEU Maritime rules governing the greenhouse gas intensity of energy used by ships calling at European ports.
