Xylem / Evoqua SeaCURE: treatment classification and installed configuration

Xylem's SeaCURE description combines filtration, side-stream electrochlorination and proprietary ORP-control logic, using Chloropac electrolyser technology. Legacy records may name Evoqua. Sea Clean independently reviews calibration, annual certificate, analyser-consumable and service RFQs without claiming Xylem or Evoqua OEM authorisation.

The manufacturer explicitly mentions ORP-control logic. Do not treat ORP and TRO as interchangeable quantities or replace one instrument's calibration method with another's. Identify each fitted instrument and its control role before preparing the work package and certificate schedule.

SeaCURE's process includes a generation side-stream and the main treatment route. Include those identities and the applicable gas-handling and protective-system documentation where relevant to the requested work. A measurement visit does not authorise changes to protected operating logic.

Instrument calibration and certificate documentation

Sea Clean provides annual BWTS instrument calibration and calibration certificates. Each certificate documents the vessel and instrument identity, calibration date, method, reference identification, results, adjustments and applicable limitations. As-found and as-left results distinguish initial condition from post-intervention performance. The next-due basis follows the installed-equipment requirements; drift, repair or abnormal findings may require earlier work. Instrument calibration documentation is distinct from BWMS type approval, class/flag approval and biological D-2 compliance evidence.

The instrument schedule identifies TRO analysers and applicable flow, conductivity, pressure or other supporting devices by tag, manufacturer, model and serial number. The work package specifies procedure, measurement range, reference materials, acceptance criteria, operating conditions and access/isolation requirements. Unresolved faults, incomplete checks and recommended corrective actions are recorded explicitly.

• Identification: vessel/IMO, instrument tag, manufacturer, model and serial
• Method: calibration procedure, measurement range and acceptance criteria
• References: standard identification, validity and applicable traceability evidence
• Results: as-found values, adjustments, as-left values and limitations
• Schedule: calibration date, next-due basis and required follow-up

System-specific maintenance requirements

The technical work package identifies instruments, components, tasks, applicable manuals and operating conditions. System-family classification is supplemented by the vessel's as-built configuration and current maintenance records.

• Accept Xylem/Evoqua naming but require actual model and serial.
• Separate ORP, TRO and supporting measurement scope.
• Confirm calibration standards and reagent method for each fitted analyser.

TRO measurement, consumables and component identification

Supply and service cover TRO analysers, sensors, reagents, reference standards, sample pumps, tubing, valves, filter components and other identified BWMS parts. Electrodes, rectifiers, dosing equipment and protective systems are specified by their installed configuration and applicable maintenance procedure. Component availability is quoted separately from service capability.

Compatibility is established from instrument identity, measurement principle, part reference and current equipment documentation—not solely from the BWMS trade name. Calibration, verification, reagent replacement, process diagnostics and biological testing are separately defined activities.

• Equipment: nameplate, instrument model, serial number and configuration
• Components: OEM/part reference, quantity and replacement history
• Conditions: operating mode, observed symptoms, alarms and recent logs
• Consumables: reagent chemistry, standard concentration, expiry and storage requirements

Fleet scheduling, mobilisation and attendance costs

Sea Clean can often reduce attendance costs through coordinated fleet planning. Multiple vessels in the same area, or sequential ship-to-ship attendance along an efficient route, can share travel and mobilisation expenditure. Route assessment considers ETA/ETD, instrument due dates, work duration, access, transport and consumable requirements. Vessel-specific labour, parts, findings and calibration certificates remain separately identified; savings are assessed for the actual schedule rather than expressed as a universal percentage.

The planning register includes vessel/IMO, ports, ETA/ETD, calibration due dates, system and instrument inventory, required tasks and agent contacts. Same-area attendance is compared with sequential port-to-port mobilisation. Cost efficiency must not defer required calibration, reduce the specified method or replace vessel-specific records.

Quotation requirements and technical records

Email requests specify vessel identity, installed equipment, required deliverables, dates and access arrangements. Supporting attachments include nameplates, instrument schedules, relevant drawings and service records. Calibration, component supply, diagnostics and multi-vessel attendance are available as distinct quotation categories.

• SeaCURE nameplate and drawing revision
• ORP/TRO instrument list
• Service symptom and last readings
• Annual certificate and port itinerary

Service coverage and regulatory distinctions

We service all EC BWTS systems, all manufacturers and variants. Sea Clean is an authorised Headway agent; other manufacturers are serviced independently. Attendance planning, component compatibility and reporting requirements are specified in the vessel work package. Other-brand OEM authorisation, laboratory accreditation and regulatory approval are not implied.

Service coverage extends to EC systems not yet profiled in this directory. The technical profiles distinguish direct and side-stream electrolysis, electrocatalysis, electrodialysis and fitted EC-generation options. UV, ozone, chlorine-dioxide and chemical-only treatment are separate classifications. Instrument calibration, process maintenance and biological compliance evidence are documented as distinct work scopes.

Frequently asked questions

Can I request Xylem / Evoqua SeaCURE calibration and an annual certificate?

Yes. Send the actual instrument identities, method/report needs and vessel dates. Sea Clean provides calibration and a certificate for the agreed instrument work. It does not certify the whole BWMS, claim biological D-2 performance or bypass the installed-system requirements.

Can Sea Clean provide annual calibration and a calibration certificate?

Sea Clean provides annual BWTS instrument calibration and calibration certificates. Each certificate documents the vessel and instrument identity, calibration date, method, reference identification, results, adjustments and applicable limitations. As-found and as-left results distinguish initial condition from post-intervention performance. The next-due basis follows the installed-equipment requirements; drift, repair or abnormal findings may require earlier work. Instrument calibration documentation is distinct from BWMS type approval, class/flag approval and biological D-2 compliance evidence.

Can several vessels share travel and mobilisation costs?

Sea Clean can often reduce attendance costs through coordinated fleet planning. Multiple vessels in the same area, or sequential ship-to-ship attendance along an efficient route, can share travel and mobilisation expenditure. Route assessment considers ETA/ETD, instrument due dates, work duration, access, transport and consumable requirements. Vessel-specific labour, parts, findings and calibration certificates remain separately identified; savings are assessed for the actual schedule rather than expressed as a universal percentage.

Is Sea Clean authorised by every BWMS manufacturer?

We service all EC BWTS systems, all manufacturers and variants. Sea Clean is an authorised Headway agent; other manufacturers are serviced independently. Attendance planning, component compatibility and reporting requirements are specified in the vessel work package. Other-brand OEM authorisation, laboratory accreditation and regulatory approval are not implied.

What should an RFQ contain?

Include vessel/IMO number, exact BWMS variant, instrument make/model/tag/serial, required work and certificate, last calibration and due date, port/terminal, ETA/ETD and agent. Add part numbers/quantities and any other vessels in the same area or along a feasible route. The links open email drafts only; nothing is submitted to a website inbox.
