About Us

Bunker One is shipping’s all in one source for marine fuels. With us, bunker supply works the way it should.

SUPPLYING THE
WORLD’S FLEET

Shipowners and operators need a marine fuel supplier they can rely on. The one who delivers their requirements. No surprises, no compromises.

For more than decades, Bunker One has delivered marine fuels at sea, at anchor, and in port through local teams and owned or operated assets.

By managing the delivery process end to end, we provide reliable fuel delivery, support compliance requirements, and keep bunkering predictable.

working as one

Experts on land and at sea

Our culture is shaped by the realities of the maritime industry. Our people are directly involved from planning and nomination through to delivery and documentation, and take responsibility from start to finish. Decisions are made close to the operation, with clear communication and close coordination.

This way of working is built on strong teamwork and a culture of continuous learning. We have a truly, connected way of working that starts in the office, and extends to our vessels, crews, terminals, port operators, and of course our clients.

RELIABILITY AND RESPONSIBILITY IN EVERY DELIVERY

Fleet Governance

Our Group Fleet Policy governs time charters, spot charters, and bareboat vessels. Through structured vetting processes and robust incident reporting, we actively mitigate operational and compliance risk across our fleet.

Vessel Vetting

Safety standards are non-negotiable. Over 95% of our operational tonnage is vetted by oil majors through OCIMF’s Ship Inspection Report Programme (SIRE), ensuring vessels meet stringent requirements for safety, crew welfare, and operational integrity.

New Fuels in Our Fleet

Using new fuels in our own fleet (including B100) gives us the insight to supply alternative marine fuels safely, reliably, and transparently — from biofuels, FAME, methanol to LNG.

ESG Policy

Our ESG team monitors performance, prioritizes initiatives and benchmarks targets to drive measurable progress. Bunker One has achieved the EcoVadis Gold Medal for its ESG efforts.
