A compact seawater RO plant can still lose days when one seal, sensor or chemical shipment misses the boat. Service planning should therefore begin with travel time, storage conditions and failure consequences, then connect each stocked item to an approved bill of materials. The BOKAWATER SWRO-2, SWRO-3 and SW-02 pages identify product families; the final service package must follow the quoted configuration.
1. Measure the real service delay
Map normal and emergency routes from supplier to port, airport, island and plant. Record customs steps, sailing or flight frequency, seasonal weather limits, lifting restrictions, security access, technician permits and local working hours. For every critical component, calculate detection time, approval time, supplier lead time, transport, customs, last-mile delivery and installation time instead of using one vague lead-time figure.
Classify consequences separately: reduced production, complete outage, unsafe operation, off-specification water or environmental noncompliance. Compare the maximum tolerable outage with available product-water storage and demand controls. This determines which items belong on site, at a regional hub or under a supplier call-off agreement; it does not justify promising a universal availability percentage.
2. Build a configuration-controlled stock list
Start from the approved equipment list, drawings and serial numbers. Include consumables such as cartridges, chemicals and calibration solutions; wear parts such as seals, O-rings and valve kits; and selected critical items such as sensors, dosing-pump parts, contactors, fuses, drives or pump service kits. Record manufacturer part number, compatible equipment revision, quantity, shelf life, storage range, inspection interval and reorder point.
Store chemicals by their safety data and local rules. Protect electrical parts and tools from humidity and salt spray, and keep membrane elements within the specific manufacturer's transport and storage requirements. Manuals distinguish installed-system preservation from unopened spare-element storage. Never substitute a generic preservation schedule or chemical without written approval for the installed membrane and local disposal route.
3. Turn shutdown and support into executable procedures
Prepare separate instructions for routine stop, power loss, storm isolation, extended lay-up and restart. Define flushing-water source, valve positions, chemical isolation, protection against air entry and backpressure, preservation checks, temperature limits, sampling, product diversion and authorization to return water to service. Assign each step to a named role and test communication before the wet season or travel disruption.
The handover package should include multilingual operating procedures, drawings, backups of controller settings, alarm list, remote-access boundary, data trend export, training records and escalation contacts. Run a tabletop exercise for a failed sensor, dosing pump and high-pressure component. Confirm what can be diagnosed locally, what evidence the remote specialist needs, and which tasks require an authorized technician. Review stock after every use and whenever the equipment revision changes.
Data to collect before comparing proposals
| Parameter / interface | Unit / format | Why it matters |
|---|---|---|
| Planning item | Evidence to record | Procurement decision |
| Travel route | Flights or sailings, weather limits, customs and last mile | Realistic mobilization time |
| Water reserve | Usable storage, demand and minimum service level | Maximum tolerable outage |
| Installed identity | Model, serial, revision, drawing and part number | Correct spare compatibility |
| Consumables | Use rate, shelf life, storage and reorder point | Site quantity and replenishment |
| Critical spares | Failure consequence, lead time and replacement skill | Site, hub or supplier stock |
| Storage | Temperature, humidity, salt spray and chemical segregation | Required cabinet or warehouse |
| Shutdown | Flush, isolation, preservation, inspection and restart | Separate procedure for each duration |
| Remote support | Data, network boundary, contacts and response path | Diagnosable tasks and escalation |
| Exercise | Scenario, participants, findings and corrective owner | Readiness before disruption |
