Water-ingress detection reports liquid at specified spaces using the fitted sensors and alarm arrangement. Coverage and performance requirements depend on vessel type and applicable rules.
Seanav Marine provides independent service assessment. Send the equipment identity, symptoms and attendance window so the required capability, parts and any manufacturer involvement can be confirmed.
What should the service assessment check?
The following items define a starting scope for a competent service assessment. The actual test method and acceptance criteria must come from the installed equipment documentation and the agreed job scope.
- Sensor location and contamination condition.
- Wiring and power integrity.
- Alarm mapping and required station indication.
- Fault detection and approved functional tests.
What must be distinguished before testing?
Do not assume a bilge pump control float meets the requirements for an independent water-ingress detection system.
What changes for engine-room flooding detection?
Define the monitored engine-room locations and the alarm path to the responsible watchkeeper. Verify the fitted sensing method, accessible wiring, channel identification and fault indication under the vessel’s test plan. Cargo-space water-ingress requirements must not be assumed to describe every engine-room installation. A test at the display alone does not prove the condition of every field sensor.
Is a water-ingress alarm enough to locate a leak?
No. It identifies a monitored condition at a fitted sensing point. Establish the sensor location, channel mapping and actual compartment condition through the vessel’s response procedure. Investigate a persistent alarm before attributing it to the sensor.
Details that help assess this equipment
- Alarm channel and compartment.
- Local observations made under vessel procedures.
- Sensor model and cable-fault indication.
Equipment references and their scope
- Kongsberg Maritime: tank sounding and draft sensors — Marine pressure-based draft and tank measurements and level switches.
These references explain equipment or system examples. They do not establish the fitted configuration, SEANAV manufacturer authorization or a vessel’s acceptance limits. Use the installed model’s documentation for the actual work.

How service is planned
Agree the affected machinery, safe isolation, operational restrictions and equipment-specific test plan with the vessel. Preserve as-found settings and available configuration backups. Confirm proposed changes and compatible replacements before work.
Record the completed work, functional-test results, outstanding defects and operating limits. Changes affecting approved functions need the appropriate maker, owner or approval-body review.
Maintenance, survey and documentation
Maintenance intervals and calibration methods depend on the manufacturer’s instructions, service conditions and vessel PMS. There is no blanket annual calibration or five-year overhaul rule for every automation component. Statutory and Class survey requirements must be established for the particular vessel and equipment.
A service report records the work performed and observed results. It does not by itself issue or renew a ship’s statutory certificate. Manufacturer authorization, specialist calibration and survey witnessing must be confirmed where required; Seanav Marine’s independent service role does not imply direct OEM agency or universal Class approval.
Request water ingress and flooding alarms support
Send the vessel name and IMO number, port, ETA/ETD, equipment maker and model, fault description, alarm screenshots and relevant drawings or logs. State whether the request involves routine maintenance, a defect, replacement, retrofit or an upcoming survey. Attendance depends on access, engineer availability, parts and the confirmed scope.
