Refurbished
The Sulzer RTA58 Marine Main Engine is a low-speed two-stroke crosshead diesel engine developed for efficient and reliable marine propulsion. As a member of the highly successful Sulzer RTA engine family, the RTA58 has been widely installed onboard bulk carriers, container vessels, oil tankers, chemical tankers, and other commercial ships operating throughout the world.
The Sulzer RTA series became one of the most respected propulsion engine platforms in the maritime industry due to its outstanding fuel economy, robust construction, operational reliability, and long service life. The RTA58 continues this tradition by providing dependable propulsion power while maintaining excellent thermal efficiency and low operating costs.
The engine's low-speed design allows direct coupling to the propeller, maximizing propulsion efficiency and reducing mechanical losses. This configuration is particularly beneficial for long-distance ocean-going vessels where fuel economy and reliability are essential.
For shipowners, technical managers, and marine engineers, the Sulzer RTA58 remains a proven propulsion solution supported by extensive spare parts availability and worldwide technical expertise. SM MARINE SERVICE™ provides supply, repair, overhaul, troubleshooting, and spare parts support for Sulzer RTA58 engines worldwide.
The Sulzer RTA58 is designed as a low-speed crosshead marine diesel engine for direct-drive propulsion applications. Operating on the two-stroke combustion principle, the engine delivers high power output combined with exceptional fuel efficiency.
The crosshead engine design separates combustion forces from piston side thrust, significantly reducing wear on cylinder liners and pistons. This engineering concept contributes to longer maintenance intervals and increased engine longevity.
The RTA58 incorporates advanced fuel injection technology, optimized scavenging systems, efficient exhaust arrangements, and heavy-duty structural components. These design features allow the engine to maintain reliable performance during extended voyages and varying operating conditions.
Commercially, the Sulzer RTA58 remains important because many vessels equipped with this engine continue to operate globally, creating continuous demand for spare parts, technical support, maintenance services, and engine overhaul solutions.
SM MARINE SERVICE™ supplies spare parts and technical services for vessels operating Sulzer RTA58 propulsion systems.
