6 INSTALLATION
6.1 INTRODUCTION
This specification sets out the requirements for the installation, operation and maintenance of an
Oilcon
®
Oil Discharge Monitoring and Control System on board a typical tanker. It should be studied
carefully before actually commencing any operation or work.
For the purpose of installation the system can be divided into 4 categories:
1. Pump room equipment and related deck ancillaries (hazardous area)
2. Bulkhead penetrations
3. Engine room equipment * (non-hazardous area)
4. Control room equipment ** (non-hazardous area)
The exact location of the separate elements within these categories will vary from ship to ship but
the specific location of some units relative to others is important.
In addition to safety precautions which must always be strictly observed for work in hazardous
spaces, installation undertaken at sea, with the ship underway, require additional precautions.
*
It is recognised that for some vessels the pump room and engine room are not adjacent. If
this is the case, it will be necessary to mount the electrical equipment in some other suitable
non-hazardous space adjacent to the pump room.
** Again, some vessels may not have a cargo control room. If this is the case, some other
convenient area must be identified, such as the navigation bridge, the engine room or the
accommodation area.
CAUTION:
ANY COMPONENTS MOUNTED ON OPEN DECK OR IN AREAS LIKELY TO
ENCOUNTER TEMPERATURE AT OR BELOW FREEZING SHOULD BE
PROTECTED ACCORDINGLY AGAINST FREEZING.
6.2 UTILITIES
For operation of the Oilcon
®
Oil Discharge Monitoring and Control System the following utilities are
required:
6.2.1 Fresh water supply
An uninterrupted supply of fresh water free of any contamination is important for a correct operation
of the Oilcon
®
Oil Discharge Monitoring and Control System, as the freshwater is used to keep the
pipework and the windows of the detection cell clean and to perform a Zero check prior to operation
of the system.
Fresh water supply conditions
Nominal inlet pressure 1,5 bar (0,15 MPa)
Maximum inlet pressure 6 bar (0,6 MPa)
Average consumption 0,13 l/min
Maximum consumption 8 l/min, during FLUSH
Water temperature range
10°C – 65°C
