The offshore supply vessel M/V Mary Cheramie underway in open water

Offshore Support Vessels

Offshore support vessels carry crews, cargo, fuel and equipment to open-water worksites. Laborde Products supports offshore operators with marine diesel engines, parts and service resources for vessels working in demanding oil and gas environments.

Offshore Applications That Demand More from Your Engine

Every hour offshore puts pressure on equipment. Heat, saltwater, load demands and long run times all affect engine performance, especially on vessels operating far from immediate service access.

Laborde supports offshore applications including crew boats, supply vessels and liftboats with power solutions built for sustained operation. For offshore support vessels, the right engine has to deliver dependable output, practical service access and long-term durability without creating unnecessary maintenance problems.

Offshore Boat Engines Built for Real-World Work

Offshore boat engines need to perform under load, operate reliably over long hours and remain serviceable in tough conditions. Mechanical simplicity, parts availability and field support all matter when vessels are working away from shore.

Mitsubishi Marine engines such as the S12R and S16R are popular options for offshore vessel applications because they offer strong output, large-displacement power and straightforward maintenance. Laborde Products can help operators compare Mitsubishi Marine options and match engine selection to vessel requirements, duty cycle and support needs.



Power Systems for Vessels in the Oil and Gas Industry

Laborde works with shipyards and operators to support offshore vessels used in the oil and gas industry. Engine selection can affect uptime, emissions compliance, maintenance planning and long-term operating costs.

Our team helps operators review marine diesel engine options, plan for service intervals, identify parts needs and support repower or replacement projects. From installation planning to overhaul support, Laborde helps offshore operators keep power systems aligned with the realities of daily marine work.

Offshore Powerboat Engines in Action

Mitsubishi S12R-Y3 marine diesel engine for offshore support vessels

Mitsubishi S12R-Y3

A fully mechanical 12-cylinder Mitsubishi Marine engine used across many offshore support vessels. The S12R-Y3 is known for high torque, long service life and straightforward maintenance.

Mitsubishi S16R-Y3 16-cylinder marine diesel engine for heavy offshore operations

Mitsubishi S16R-Y3

Built for heavier loads and larger platforms, this 16-cylinder Mitsubishi Marine engine supports high-output offshore vessel operations with water-cooled performance and direct injection.

Results from the Field

M/V Mary Cheramie

This repower project replaced aging equipment with twin Mitsubishi S12R Tier 3 engines. The updated setup helped improve reliability, reduce emissions and improve service access for a vessel operating in a demanding offshore environment.
