One problem. One solution. One process.

The Rigby Process® converts high-sulfur marine fuel into IMO 2020 compliant VLSFO or ULSFO. No blending. No workarounds. Just a patented process that works.

We remove the sulfur. You keep the fuel.

The Rigby Process® takes your HSFO and converts it directly into compliant VLSFO (0.5% S) or ULSFO (0.1% S) — preserving the energy density and properties your engines were designed for.
The process removes sulfur and contaminants from residual fuel streams while preserving their core properties.

Input: High Sulfur Fuel Oil (HSFO)
Output: High-value compliant fuel
Yield: Up to 96% usable product

This allows refineries and terminals to convert residuals into premium market-ready products.

The fuel that powered the global fleet is no longer permitted.

Since January 2020, HSFO with 3.5% sulfur content cannot be used as marine fuel without a scrubber. Refineries and terminals are sitting on surplus residual material with limited market value. Ship operators need compliant fuel that their engines are actually designed for.
The industry needed a real solution — not a blend, not a compromise.

Business Model

Our model is built on a long-term, asset-backed structure that combines industrial deployment with stable revenue generation.
Investment Structure

Amura Energy acts as investor and asset owner, developing modular refining units based on the Rigby Process®.

Module capacity: 20,000 barrels/day
Annual production: ~7 million barrels
Investment per module: ~USD 250 million
Operating life: 20 years
Construction timeline: ~16 months

Revenue Model

We operate under a tolling structure, ensuring predictable and recurring income:

Clients supply HSFO feedstock
We process and convert it into compliant fuel
Clients pay a tolling fee per barrel

Output distribution:

~96% VLSFO
~2% sulfur
~1% naphtha
~99% total product utilization

Scalable Infrastructure. Predictable Returns.

The model creates immediate economic upside for clients:

Converts low-value residuals into premium products
Generates additional margin without new refining complexity
Eliminates regulatory constraints on HSFO usage

Risk Mitigation

Client Value Proposition

Contract Framework

Long-term agreements ensure investment security:

Minimum duration: 20 years
Guaranteed supply of feedstock (20k barrels/day)
Guaranteed payment of tolling fees
Structured risk allocation between parties

The model is designed to minimize exposure:

Stable demand driven by regulatory requirements
Proven industrial technology
Secured input supply through contracts
Predictable cash flows via tolling structure

The system is structured to create equilibrium:
