Headway OceanGuard Spare Parts and Consumables
Updated
Keeping a Headway OceanGuard BWTS in service depends on the right spare parts and consumables: filter elements and seals, EUT treatment unit components, TRO analyser parts and reagents, instrumentation and control items. As an authorized Headway agent, Sea Clean AS supplies genuine OceanGuard parts matched to the exact unit revision. This article covers the main part groups, how to identify the correct item and how supply is arranged.
Key takeaways
- OceanGuard is type-approved as a configured system, so genuine, correctly identified parts protect both performance and approval validity.
- Filter elements, seals and backflush components are the most frequently replaced wear items on uptake.
- EUT treatment unit electrodes and seals must be matched to the exact unit revision and verified after fitting.
- TRO sensor parts, reagents and sodium thiosulfate neutraliser are critical consumables supplied in date and labelled for the vessel.
- Many apparent treatment faults trace to flow meters, valves or instrumentation, so supporting spares keep the system available.
- Quote model, serial number and unit revision to receive the correct genuine part the first time.
Why Genuine, Correctly Identified Parts Matter
A BWTS is type-approved as a configured system, so fitting an incorrect or non-genuine part can affect both performance and the validity of the approval the vessel relies on for compliance. For OceanGuard this is particularly relevant to the filter, the EUT treatment unit and the TRO analyser, where a wrong element, electrode set or sensor can change treatment behaviour or give false readings.
As an authorized Headway agent, Sea Clean supplies genuine OceanGuard parts and identifies the correct item against the unit's model and revision. Headway has produced several OceanGuard generations and capacity ratings, so the same functional part can differ between units, and matching it properly avoids fitting an item that does not seat or interface correctly.
Correct identification starts with the system nameplate, the unit serial number and, where available, the original parts list for that vessel. Supplying these details with an enquiry is the most reliable way to receive the right part the first time.
Filter Elements, Seals and Backflush Parts
The automatic backflushing filter is the first wear point on uptake. Its screen or candle elements, seals and gaskets, and the backflush valve and drive components are the parts most often replaced during planned maintenance, because they handle sediment and biological load on every ballasting operation.
A filter that is fouled, torn or fitted with the wrong mesh will either pass too much material to the treatment unit or raise differential pressure until the system trips or bypasses. Carrying spare elements and seal sets sized for the specific filter model lets an engineer restore filtration in a single attendance rather than waiting for parts.
Sea Clean supplies filter elements, seal kits and backflush components for the relevant OceanGuard filter variants, and can advise on the maintenance interval suited to the vessel's trading pattern and water quality.
EUT Treatment Unit Components
The electrocatalysis (EUT) treatment unit is where disinfecting oxidants are generated. Its electrodes, internal seals, connections and any associated power and control components are subject to scaling, erosion and electrical wear over time, and their condition directly affects treatment effectiveness and power draw.
Electrode condition is monitored through operating parameters; a unit that needs increasing voltage to reach the same output, or that scales rapidly, signals that inspection and parts may be due. Replacing electrodes and seals with genuine components keeps the treatment unit operating within its design envelope.
Because the treatment unit is central to compliance, Sea Clean matches EUT parts precisely to the unit revision and supports the work with service attendance where the replacement requires it, so the unit is verified after the parts are fitted.
TRO Sensors, Reagents and Neutralisation
Total residual oxidant measurement governs both treatment confirmation and safe discharge, so the TRO analyser and its consumables are critical consumable items. Sensor parts, reagent packs and the analyser's wear components are replaced on a schedule because a drifting or starved analyser produces alarms and unreliable readings.
Sea Clean supplies TRO sensor parts and reagents, as well as sodium thiosulfate neutraliser used to reduce residual oxidant on discharge where required. Reagents are supplied in date and labelled for the receiving vessel, with attention to shelf life so the engineer is not left with stock that expires before it can be used.
Keeping a verified analyser and in-date reagents on board is one of the most effective ways to avoid discharge-related alarms and to pass a port state control check that examines residual oxidant control.
Instrumentation, Valves and Control Parts
Beyond the core treatment items, OceanGuard relies on flow meters, pressure and level instrumentation, control valves and actuators, and electrical and PLC components. Many apparent treatment faults trace back to one of these supporting items, for example a flow meter reading low, a valve not stroking fully or a sensor giving an out-of-range signal.
Spares for these items keep the system available and prevent a single instrument fault from holding a vessel in non-compliant operation. Sea Clean supplies instrumentation, valve and control components for the relevant OceanGuard configurations.
Where a control or software issue is involved, authorization gives Sea Clean a route to Headway technical support so the right component and settings are applied rather than a part being swapped speculatively.
Ordering, Lead Time and Delivery
An efficient parts order starts with the system model, serial number, unit revision and a description of the symptom or the part position. With these, Sea Clean identifies the genuine item and confirms availability, whether it is held in Norway or sourced from Headway.
For Norwegian and North Sea calls, parts held locally can often reach the vessel quickly by road or short freight; for worldwide calls, items are routed by courier or air freight and coordinated with the local agent, so lead time depends on freight and customs rather than identification. Consolidating several parts and reagents into one delivery simplifies receipt during a short port stay.
Send enquiries with vessel name, IMO number and the system details to post@seaclean.no. Early notice of an upcoming service interval lets parts be staged against the vessel's schedule rather than ordered reactively after a breakdown.
Frequently asked questions
Are OceanGuard parts from Sea Clean genuine Headway parts?
Yes. Sea Clean is an authorized Headway agent and supplies genuine OceanGuard spare parts and consumables. Parts are identified against the unit model, serial number and revision so the correct item is supplied for the specific installation.
What information do you need to supply the right part?
The system model, unit serial number and revision, plus a description of the part position or symptom, allow the correct genuine part to be identified. The vessel name and IMO number are also needed for documentation and delivery coordination.
Do you supply TRO reagents and neutraliser as well as parts?
Yes. Sea Clean supplies TRO test reagents and sensor consumables and sodium thiosulfate neutraliser. Reagents are supplied in date and labelled for the receiving vessel, with attention to shelf life so stock is usable when it reaches the engineer.
How long does delivery take?
For Norway and North Sea calls, locally held parts can reach the vessel quickly. For worldwide calls, parts are routed by courier or air freight and coordinated with the local agent, so lead time depends on freight and customs rather than on identifying the part.
