The document follows the engine from project definition through installation and operational planning. It gives the reader a structured view of how the MAN L35/44DF is rated, started, loaded, controlled and connected to plant systems. The contents include engine data for 6, 7, 8, 9 and 10 cylinder in-line configurations, along with application-specific planning data for auxiliary GenSet, electric propulsion and mechanical propulsion with controllable pitch propeller. It also sets out the media requirements for lube oil, cooling water, diesel fuel, heavy fuel oil, pilot fuel, natural gas, compressed air and inert gas.

Engine and Plant Planning Content

The guide identifies the MAN L35/44DF as a four-stroke dual fuel engine compliant with IMO Tier II. It describes liquid fuel mode and gas mode, including pilot fuel ignition in gas operation, and explains that engine power in gas mode is generally equal to the power generated in liquid fuel mode. The engine can run in liquid fuel mode, gas mode and a backup mode described in the fuel system section. Starting and stopping are carried out in liquid fuel mode.

Engine design information includes the 350 mm cylinder bore, 440 mm piston stroke and 42.3 litre displacement per cylinder. Standard ratings are shown for 720 rpm and 750 rpm operation, with outputs such as 3,060 kW for the 6-cylinder 720 rpm rating and 5,300 kW for the 10-cylinder 750 rpm rating. The guide also covers fuel stop power, overload limits, derating factors and application-specific available output.

Operational planning material includes starting modes, prelubrication and preheating requirements, slow turn, load application phases, load steps for GenSet and electric propulsion applications, CPP load application, low-load limits, load reduction as a protective measure, run-down cooling and arctic operating considerations. These sections are relevant when preparing plant automation, power management and propulsion control strategies around the engine.

Systems and Installation Reference

The fuel section describes both liquid fuel and gas supply arrangements. It covers MDO treatment and supply, HFO treatment and supply, pilot fuel supply, fuel gas supply, gas valve unit functions, double-wall gas piping, ventilation requirements and inert gas purging. The cooling water section describes HT and LT circuits, charge air cooling, nozzle cooling, preheating modules and cooling water treatment. The lube oil section covers service tanks, pumps, filters, separators, prelubrication and postlubrication, crankcase venting and tank venting.

Engine automation content describes the SaCoSone system, including the control unit, injection control modules, knock control module, combustion control unit, power distribution unit, interface cabinet, auxiliary cabinet, gas valve unit cabinet, local operating panel and remote operating panel. It explains power supply requirements, control station changeover, speed setting, safety functions, alarming, speed control and interfaces to plant systems.

Installation planning is supported by main dimensions, weights, removal dimensions for pistons, cylinder liners and charge air coolers, lifting device information, maintenance space requirements and foundation recommendations. Exhaust gas ducting, silencer and boiler installation, explosion venting devices, purging and insulation are also addressed.

Practical Service and Reference Use

This MAN L35/44DF Marine Dual Fuel Engine Project Guide – IMO Tier II PDF is useful when a technician or project engineer needs to check engine ratings, plan fuel and cooling systems, confirm starting and load application conditions, review automation interfaces or prepare engine room layouts. It supports specification checks for lube oil, fuel oil, natural gas, cooling water and compressed air. It also helps with understanding derating, emissions, noise, vibration and foundation requirements.

The guide is not a workshop repair manual for stripping and rebuilding the engine. Its value lies in project-level technical data, operating requirements and system descriptions that must be respected when the engine is integrated into a marine plant. It gives the user a single reference for engine-related planning decisions and for checking that connected systems meet the engine manufacturer requirements shown in the document.
