The Wärtsilä Land & Sea Academy's "Engine ZA40S Operation and Practical Advanced Course" file details the ZA40S diesel engine, a modern in-line and vee-form, four-stroke engine developed from the Z40 and ZA40. It highlights the engine's economic efficiency through optimized turbocharger and engine design, low specific fuel consumption, and extended overhaul intervals. The document covers the engine's history, design evolution, major components (crankshaft, cylinder block, bearings, cylinder liner, cylinder head, pistons, connecting rods), and maintenance procedures. Key features include the anti-polishing ring for reduced wear and stable lube oil consumption, and SOLAS requirements for fuel pipes. The file also outlines tools, tightening torques, estimated component service life, and procedures for crankshaft deflection checks and vibration damper sampling.

The government file details a mandatory training requirement for the USCGC HEALY crew, specifically for Wartsila/Sulzer Advanced Engine Maintenance. This training, designated course code 501425, is essential for the proper operation and maintenance of the vessel, especially during deployments in Arctic zones. The five-day, face-to-face course, scheduled for March 16-20, 2026, at Wartsila North America in Ft. Lauderdale, FL, is designed for marine and power plant personnel with basic knowledge of diesel four-stroke engines. The curriculum covers engine component design and function, built-on systems, fuel, lubricating oil, cooling water, control, and starting air system requirements, engine operation (start/stop), evaluation of operating data, and practical maintenance procedures. Key learning objectives include understanding engine components and systems, the role of various oils and water in engine performance, start-stop procedures, data evaluation, and main overhaul procedures with an emphasis on safety.
