Shipping moves the world We make it cleaner

Old fuel. New standard

We're Amura Energy. We work with Rigby Refining to bring ports, refineries, and shipping companies around the world a technology that transforms the most polluting marine fuel into something ships can actually use without damaging the planet.

This isn't a promise. It's a patented, proven process ready to deploy.

The numbers behind the process

Every barrel we process delivers measurable results. These aren't projections — they are the outcome of a patented, proven technology.

-80% SOx. Sulfur oxide emissions reduced per barrel processed
-60% NOx. Nitrogen oxide emissions reduced vs HSFO combustion
-96%. Mass retention — your HSFO returned as market-ready VLSFO
20,000 bbl/day Processing capacity per module

Our Services

We don't offer a one-size-fits-all product. We work with refineries, terminals, and shipping companies to find the right configuration for each project.

For Refineries

Your storage is full of HSFO that the market no longer wants. The Rigby Process® transforms that stranded asset into IMO 2020 compliant VLSFO production — ready for the global fleet.
→ Convert stranded HSFO into high value product
→ 96% mass retention
→ Tolling fee model — no feedstock purchase needed

For Ship Owners

For Terminals

You're sitting on surplus HSFO with limited market value.
We convert it into premium VLSFO production — without changing your crude slate or your existing infrastructure.
→ Maintain your pre-IMO 2020 crude slate
→ Clear all residuals at premium market value
→ Small footprint, fast to deploy

You need compliant fuel that your engines were actually designed for — not a blended compromise. Our VLSFO production delivers the energy density and properties of HSFO, fully IMO 2020 compliant.
→ Same engine performance, zero sulfur penalty
→ No cat fines, no blending issues → ULSFO available for ECA markets at 0.1% S

Same fuel. No sulfur. Full compliance.

IMO 2020 changed the rules. We changed the fuel.
Most companies adapted to the regulation. We solved the problem behind it.
The result is a cleaner, compliant marine fuel — without sacrificing energy density or engine performance.

Why now?

In 2020, the International Maritime Organization changed the rules. The high-sulfur fuel oil that had powered the global fleet for decades was no longer permitted. The industry scrambled for alternatives. We already had one.
