Bilge pumps are critical pieces of equipment on a small craft. There are many types that perform in different ways that a surveyor needs to understand.

Join IIMS President, Geoff Waddington, on Tuesday 23 March 2021 at 10.00 (UK time) for ‘Surveying bilge pumps in small craft – what surveyors and MCA coding examiners need to know’. A copy of the video can be purchased if you are unable to attend in person.

The agenda:
10.00 – 12.00 Geoff talks bilge pumps in depth.
12.00 – 12.40 Matt Edmond, Product Manager, Jabsco
12.40 – 13.10 Specific aspects of the MCA codes relating to bilge pumps are to be covered off.

The presentation will cover:
• Types of Pump (electric) – positive displacement, remote and submersible.
• Types of Pump (manual) – diaphragm, stirrup etc.
• Operation – float, water sensors, remote switched, etc.
• Bilge sumps – sailing boats – level bilge issues.
• Strum boxes.
• Pipe-work – bulkhead penetrations.
• Non return valves – back flooding.
• Electrical supplies – wiring, junction boxes, etc.
• Environmental issues – water separators, oily water tanks, disposal, etc.

From Matt Edmond (Jabsco)
Matt will present on 3 types of submersible Jabsco bilge pumps, specifically around the types of water sensing offered.
· Standard pumps operated by external float or electronic level switch
· Timer pumps that switch on every 2.5 mins to check for water
· Auto pumps that use a level sensor
· Low profile pumps for shallow bilge areas

And specifically for MCA coding examiners/surveyors:
• What is a bilge compartment
• Which compartments require pumping
• Which compartments may, possibly, be accepted without pumps
• Main pump and emergency pump for each compartment – emergency may be common to all or not
• Types of system- manifold – individual pumps for each compartment and so on
• Pipe and hose materials – non-combustible in ERs or other fire risk spaces
• Bilge alarms – when required; where required to be located;where required to be heard and seen
• Locations of pumps as per the MCA codes
• Pump capacities for under 6 metres, 6 to 12 metres and over 12 metres
• Larger capacity requirements for cargo carrying or lifting operations
• Open boats – pumps, buckets and bailers
• Pumps on RIBs
• Pumping with deck hatches shut and possible exceptions to this
• Testing bilge pumps at survey
• Testing bilge alarms at survey
• Checking pump capacities
• Reduced capacities with increased head/height to discharge
