WinGD ex Wartsila

This document was created based on the WinGD Fuel Guideline, the “Concept guidance for distillate fuels (107.428.377) and the “Concept  guidance for fuel oil treatment (107.246.880)” and replaces these documents accordingly

This booklet shall serve as a guide for judging the condition of piston running components (liners, pistons and piston rings) for the condition-based maintenance.

For WinGD X62, X62-B, X62DF, X72, X72-B, X72DF engines ordered before January 2020

Wartsila Guide for condition of relevant piston-running components
(liner, pistons and piston rings) Version 2,1 June 2014.

The purpose of this bulletin is to provide operating instructions of AFT seal tank and the purpose of AFT seal tank installation.

Wartsila Sternguard In-water serviceable seal is available in two different versions:
- Partially split version, for installations with shaft removals in dry dock. The seal is prepared for in-water overhauls.

- Fully split version, for installations without shaft removals in-water or in dry dock.

Occasionally patches of black deposits appear on the cylinder liner wall of 2-stroke engines. The black spots may appear anywhere on the cylinder liner running surface. New cylinder liners with still honing marks (plateau honing) present seem to have a stronger tendency for black lacquer formation.

This guideline summarises the required checks to investigate possible causes in case of alarms indicating improper function of the ICU.
Unnecessary costs may be avoided by simple rectifying actions instead of an ICU replacement and shipping to a Wärtsilä service centre; e.g. exchange of available spare parts or a proper understanding of the alarms.
Should a problem not be rectified by the described countermeasures, however, replacement of the ICU must be taken into consideration.

Provides information and guidance concerning the cylinder lubrication of Wärtsilä 2-stroke engines.
The piston running behaviour of 2-stroke engines is exhibiting an ever growing complexity. The key internal factors are the changes of operation patterns (e.g. slow steaming).
