Furthermore, in the light of IMO Tier III regulations, a number of environmentoriented systems focusing on reduction of ships’ emissions is growing. Although the physics and the chemistry behind processes remain unchanged, strong requirements to optimise them in the most ecological and economical way set new horizons for Man-Machine Interfaces where Engine Crew’s qualifications play a significant role in daily operation, maintenance and diagnosing problems. On the other hand modern and technologically advanced marine diesel and dual-fuel engines with or without their associated emission control systems are expected to be simple to operate and easy to maintain. All these factors set up increasing requirements for Engine Operators’ familiarisation and training. In the demanding and constantly changing marine business world training methods which are quick, intuitive, cost efficient and motivating to self-learning are necessary for the Ship Owners to remain flexible and competitive in the market. The purpose of this paper is to present the measures taken by Winterthur Gas & Diesel Ltd. in an effort to develop modern training methods and aids that will satisfy our Customers’ needs. Winterthur Gas & Diesel Ltd., being a key player in the sector of marine two-stroke slow-speed diesel and dual-fuel engines as well as IMO Tier III solutions, has decided to address these demands and together with a development partner to support our new products with virtual simulators. The developed and presented “W-Xpert Simulator” depicts the Main Engine implemented into a Virtual Engine Room where it coexists with all ER systems including the propeller and the PTO Shaft Generator. The trainee has full interactive access to all functions offered by the real user interface of an engine including all valves, etc. located on the engine and most of the engine room system controls. The effect of the Operator’s actions on the Engine performance is visualised in the form of various virtual displays, including an engine performance monitoring system. Effects of a wear and failures of certain parts and components are considered in the simulation of engine performance and emission model. This creates Operator’s awareness about parts wear and tear influence on engine efficiency and its emissions level. In effect this unique feature of the simulator rises the level of maintenance decisions to a dimension where both thermodynamic efficiency and emission performance are understood and respected also in reality. A very realistic response of the virtual engine to the load and environmental condition changes is achieved by incorporated real engine thermodynamics and physics into the simulation. Various configurations reflecting different engine bores, a choice of propeller type (CPP and FPP) and a selection of engine tuning have been created so far. Additional motivation to choose this path was the encouraging change in STCW regulations dealing with requirements for training and competence evaluation of marine engineers. The new “Methods for demonstrating competence” as described in the 2010 Manila Conference (the Amendment to Seafarers Training, Certification and Watchkeeping Code, STCW/Conf. 2.34) allows for the first time the “Examination and assessment of evidence” based on “approved simulator” tests. Experience shows that training and self-education sessions can be carried out almost at any location and are not limited to dedicated training centres. As presented the simulator can be operated on a single standard laptop or desktop PC with one or two screens and a pair of speakers. Winterthur Gas & Diesel Ltd. will continue to add new engines and environmental solutions to the existing W-Xpert Simulator portfolio to satisfy the growing demand on modern methods of Crew training
