Graviner Mk6 Oil Mist System Detector Head
Inspection & Cleaning Process
Introduction
The Graviner OMD Detector is made of 2 assemblies, the Detector Head and the Detector
Base. The Detector Head is attached to the Detector Base with 2 Allen bolts.
The oil mist detection chamber in each Detector Head must be inspected at regular intervals
and cleaned to remove any buildup of oil splash or carbon deposits created by the operation
of the engine.
Our experience indicates that the cleaning interval will be unique to each engine and
dependant upon many factors such as the way the vessel engine is operated, the engine
temperature, the condition of the engine oil and the engine service intervals.
This Technical Note describes the tools required and the cleaning procedure to be used to
inspect and clean the Mk6 Detector.
As required by IACS M67 Graviner Mk6 OMD systems will automatically warn the Users
when the detection window becomes partially obscured and must be cleaned. Graviner
recommend establishing a cleaning and maintenance regime to minimise any Fault message
warnings of this type and maximise the service life of each Detector Head.
As a guide, the Detector Head should be cleaned and inspected every 6 months and the
sample pipe in the Detector Base cleaned and inspected every 12 months.
