RT-FLEX & WIN GD Diesel Engines

OVERALL AIM

A Training Course designed for Engineer Officers who are to be recruited in one of the nine (9) ships of Minerva Marine fitted with a Wartsila RT-Flex or Win GD (Winterthur Gas & Diesel) diesel engine. The overall aim of the course is to increase the awareness of the participants to the concept, key components, operation and maintenance on the above camshaft-less, pressurized fuel and servo oil common rail, Tier II, electronic engines.

LEARNING OBJECTIVES

To help the Engineer Officers understand:

  • the RT-Flex mechanical features including the fuel and servo oil pumps, and the function of ICU (Injection Control Unit), CLU (Cylinder Lubrication Unit) and VCU (Valve Control Unit).
  • the electronically controlled and load-dependent high-pressure, common rail systems for fuel injection and exhaust valves operation.
  • the Control System including the WECS 9520 and the UNIC Control System, the Variable Injection Timing and the Variable Exhaust Opening/Closing.
  • the function of the Flex Lube Cylinder Lubrication System and the feed rate adjustment, the importance of Service Letters issued by the maker and measures to be taken in emergency occasions.

FACILITIES

The Training Course will take place at the ATHINA Maritime Learning and Development Center
by making use of the K-Sim Engine Simulator (Class A) and Desk-Top (Class C) Simulators.

Class A (ENG): A full mission simulator capable of simulating all machinery operations in the engine control room and machinery spaces.
Class C (ENG):  A limited task marine simulator capable of simulating some machinery operations in the engine control room and machinery spaces.

For the simulated training, an engine model Wartsila 12 RT – Flex 82 (C), two-stroke, low speed, 12 cylinder configuration, turbocharged, reversible with cylinder bore 820 mm, piston stroke 2646 mm, CSR 54.24 MW with 102 RPM corresponding speed.
