Diesel outboards powering oil and gas operations

Safer, cleaner marine propulsion for offshore energy

Supporting energy operations where it matters most

From the Persian Gulf to the Java Sea, offshore oil and gas operations demand equipment that meets the highest standards for safety, reliability and environmental performance. Cox diesel outboards are engineered to thrive in these critical environments, providing a dependable and spark-free alternative to petrol-powered engines.

Cox Marine diesel outboards are already in use supporting oil and gas activity across the Middle East, Southeast Asia, and Australasia – whether it’s transferring crew, assisting with spill response, or operating on support vessels kept on standby.

In many oil-rich regions, spark ignition engines are banned due to the risk of explosion. The Cox V8 diesel outboard eliminates this hazard with compression ignition, making it the obvious choice for offshore platforms and high-risk zones.

Why Cox diesel outboards are ideal for the oil and gas industry

Spark-free safety

Petrol outboards pose an ignition risk that diesel engines eliminate. In regulated environments where spark-ignition engines are prohibited, our outboards are a compliant and inherently safer solution.

Extended operating range

With up to 30% greater fuel efficiency than petrol alternatives, operators benefit from longer running time and fewer fuel stops – ideal for vessels tasked with emergency response, logistics or continuous support roles.

Low maintenance, high uptime

Extended service intervals and ease of access for servicing mean reduced downtime and lower operational costs—a crucial factor for vessels supporting 24/7 offshore activity.

Trusted by the industry

Cox Marine works closely with distributors, operators and OEMs across the oil and gas supply chain to deliver engines that meet the needs of today’s energy sector. From real-time support to planned maintenance programmes, our commercial diesel outboards are backed by a global service network and a deep understanding of the industry.

Key features – built for oil and gas environments

Ready for rough seas

Our twin-turbo V8 diesel outboard delivers high torque at low RPM, giving operators the control and power needed to navigate tough conditions with precision.

Easy to install and maintain

A universal transom mounting pattern and commercial-grade design mean installation and servicing are straightforward – even on large standby or spill-response vessels.

Minimising emissions, maximising impact

The V8 is certified to the latest environmental standards (EPA Tier 3, RCD II, IMO II) and delivers a 30% reduction in fuel consumption compared to similar petrol outboards.
