conditions that could lead to crankcase explosions on large Diesel engines. They are typically
installed in harsh operating conditions - particularly with respect to temperature and vibration - and
are expected to provide continuous service over extended periods. They are therefore subject to
considerable wear and tear.
In order to ensu
guidelines. Given that they are components within key safety systems, as precautionary advice the
manufacturer recommends the OMD system is overhauled during the routine 5year dry-dock by a
trained and Authorised Graviner OMD Service Engineer and any faulty components are replaced at
this time

1.1 INTRODUCTION
Hightemperatures, in excessof200oC that occur on bearing surfaces underinitial failure conditions, can
lead to a rapid generation of oil vapour When the hot vapour contacts the relatively cooler atmosphere
of the crankcase it condenses into a fine mist, with typical particle sizes of around 0.5 to 5 microns in
diameter. When the density of these particles reaches between 30 to 50 mg/l (Milligrams per litre),
depending upon the type of oil, an explosive condition exists.

A fire or explosion needs three constituents: fuel, oxygen and an ignition source. Remove one of these
and no explosion will occur. Similarly, within the crankcase, the three constituents which could cause
an explosion are air, oil mist
oil mist density can be measured at levels as low as 0.05 mg/l and give early warning of a rise in oil mist
density.
Oil Mist Detection (OMD) techniques have been used to monitor diesel engine crankcases for potential
explosive conditions and early detection of bearing failures. The systems available rely mainly on
analysingtheoptical densityofoilmistsamplesdrawn fromthecrankcasecompartments, throughpipes
to the detector. While these systems proved successful in the past, engine design has improved

Nov-21 Page 13 of 132 59812-K001 Rev 10
significantly over the years and oil mist detection techniques have improved substantially to maintain
adequate protection.
The Graviner Mk 6 OMD provides the following benefits:
•Multi engine capability, up to 8 engines on a single system
•Suitable for both 2 stroke and 4 stroke engines.
•Elimination of sample pipes - reduced installation costs.
•Significant reduction in scanning time - 1 .2 seconds for a system of 64 Detectors.
•Relocating system controls and display to the safety and comfort of control room.

1.4 SYSTEM OVERVIEW
The Graviner MK6 OMD retains the long-established differential measuring system unique to
Carrier Fire & Security Limited, which enables high sensitivity to be used while maintaining the
maximum false alarm rejection. It still uses optical sensing, but light scatter instead of
obscuration. This enables very small Detectors to be used. These are rugged and designed to be
engine mounted using standard oil mist detector ports. As they each have their own means of
sample acquisition no sample pipes are required. Multiple internal light sources ensure that a
single failure will not cause the loss of a Detector. Modular construction means that a faulty
Detector can be replaced in a matter of minutes.
Each Detector continually monitors the oil mist density in the crankspace to which it is
connected. In addition, it self-checks for any internal faults. The Control Panel interrogates each
Detector in turn, notes its address, the oil mist density value and determines the health of the
Detector.
For each engine the average oil mist density from each Detector is calculated and stored. Each
Detector signal is then compared in turn with the stored average. A positive difference (the
deviation) is then compared with a pre-set, but adjustable reference (the deviation alarm level)
for that engine (or Detector). If it is greater than the reference a deviation alarm is indicated.
The stored average level is alsocompared with a pre-set reference (the average alarm level) and
an average alarm is indicated if the reference is exceeded.
A full system of 64 Detectors over 8 engines has a maximum scan time of 1.2 seconds, but with
alarm priorities that enable the system to respond if an alarm occurs.
The Control Panel separates the information according to engine groups.
The Control Panel incorporates a Liquid Crystal Display (LCD). The Main Display constantly
displays the average oil mist density reading for each engine along with the average alarm level
for each engine. It also enables the individual readings of each Detector on an engine and the
average to be displayed on demand and automatically under alarm conditions.
In theinterest of safety,all system controlsand alarm displays are locatedon the Control Panel.
However, to aid fault finding each Detector is fitted with 3 indicator lights:
Green - Power on
Red - Alarm
Amber - Fault
Each Detector also has access to its address set switches.
As all Detectors operate independently, the loss of one by either failure orthe need to clean does
not affect the operation of the rest of the system. Individual Detectors, or engine groups, can be
isolated from the rest of the system for maintenance while the rest of the system remains in
operation.
Alarm Philosophy
The system has 3 separate alarms as detailed below
1. Average Alarm - This indicates that the average oil mist levels within the engine are increasing
andthat aninvestigation shouldbeundertaken. Thisalarmwill operate theslowdown/shutdown
and the common alarm relays.
2. Deviation Alarm - This indicates that the level of a detector has increased above the engine
average level and that an investigation should be undertaken. This alarm will operate the
slowdown/shutdown and the common alarm relays.
3. Back Up Alarm - In the event of a failure of either the Control Panel or Detector software, then
the Back Up Alarm will operate the common alarm relay, but it will not operate the
slowdown/shutdown relay. This is an additional functional precaution added by Carrier Fire &
Security UK Ltd which can be connected in any way the customer requires. This is usually
connected toa warning beacon or siren; however, thecustomer maychoose toconnect the relay
to another device or to the engine slowdown or shutdown circuitry.

Nov-21 Page 18 of 132 59812-K001 Rev 10
On receipt of either an Average Alarm or Deviation Alarm the engine should, unless connected to a
slowdown/shutdown relay, be stopped if safe to do so and allowed to cool down so that the background
oil mist levels reduce before entering the engine room.
When the oil mist levels have returned to normal then the Accept and Reset buttons can be operated
from the Control Panel membrane and the system will then return to normal operation.
Fault Diagnosis
When a system fault is received, the information on the display should be noted and then the appropriate
Fault Finding procedure, detailed in section 5 Fault Finding of the manual, should be checked to enable
the fault to be rectified.
When the faults have been rectified the Accept and Reset buttons can be operated and the system will
return to normal
Event Log
All alarms, faults and events are recorded in an Event Log which is date and time stamped indicating the
type of event which can be analysed at a later date. The Event Log is a rolling list and has a capacity of
256 events.
SYSTEM CONTROLS AND DISPLAYS

The Control Panel is menu driven and provides a logical route to all functions. It has three operating
levels:
User
Engineer
Service
The User level is essentially for read only interrogation and does not allow any adjustments to be made
to alarm settings or system configuration.
The Engineer level is password protected and allows access to most functions and the full range of
programmable settings.
When selected, a prompt for a password will appear, enter 012345, when programming is completed, if
required, the Password may be changed by an authorised person to prevent unauthorised access in the
future. This process can be followed in section 2.8 of this manual.
The Service level is also password protected (different from the Engineer Menu) and allows access to
all functions. This is only available to authorised Carrier personnel and authorised Service Providers.
