How ElectroSAnMBR engages ship owners and classification societies

ElectroSAnMBR is a European Union Horizon 2020 research project developing a submerged anaerobic electrochemical membrane bioreactor for ship bilge water. It brings together electrolysis, anaerobic digestion and membrane bioreactor technology to improve the removal of oils, chemicals and organic pollutants. Its value depends on turning promising laboratory performance into treatment that vessel operators can use and reviewers can assess.

Engagement with ship owners and classification societies therefore forms part of the technical work. Operators contribute operating constraints and commercial priorities; classification societies and surveyors clarify which evidence, tests and installation arrangements matter for approval. The strongest exchange begins with shared questions, continues through pilot planning and result interpretation, and records why a design changes or a programme stops.

Starting with the owner’s operating problem

A ship owner needs more than a high removal percentage. ElectroSAnMBR must fit the available footprint, electrical supply, maintenance routine and crew competence while handling oily emulsions and chemical contaminants reliably. Those operating priorities should shape the research brief, alongside limits on waste production and the consequences of equipment failure.

In Australia, these priorities arise across a broad maritime economy: bulk carriers and coastal traders serving Newcastle, Melbourne and Fremantle, together with ship managers and marine engineering suppliers around Sydney and Melbourne. A useful discussion starts with familiar questions about space, power, access for technicians and the service network a vessel can realistically use.

The project responds by holding structured listening sessions with vessel operators, technical managers and naval architects, then translating their requirements into a concise test brief. Information requests should focus on representative bilge-water characteristics and operating patterns, with confidentiality and practical relevance built in.

Translating constraints into testable requirements

Broad concerns become useful when they become testable. Representatives can identify whether the priority is bulk oil separation, emulsion breaking, chemical removal or a combined duty, and supply details such as droplet size, detergents, salinity, temperature and load variation. Researchers can then align sampling points, analytical methods and acceptance criteria with those needs.

Owner and reviewer input should also shape the experimental programme. The work on electrocoagulation for emulsion breaking is directly relevant to how electrically induced coagulation may support emulsion breaking alongside biological treatment. Testing with representative oily feeds provides a firmer basis for comparison than relying on clean synthetic water alone.

A draft test matrix can cover steady flows, shock loads, stop-start operation, start-up and maintenance downtime. ElectroSAnMBR can share that matrix for comment before trials, then return with interim results. Such feedback keeps the reactor tied to shipboard reality and gives participants a clear view of which findings remain uncertain.

Evidence that survives operational scrutiny

A laboratory percentage alone will not satisfy either operators or technical reviewers. Relevant evidence includes inlet and outlet oil concentrations, chemical oxygen demand, targeted chemical analyses, membrane flux, solids production and electricity use per cubic metre. Each measure needs a stated method, sampling point and uncertainty range.

Classification-society specialists need repeatable procedures, calibration records, transparent sample handling and results across a realistic range of conditions. Ship owners also ask about fouling, start-up time, spare parts, operator workload and the effect of treatment on other shipboard systems. These are separate questions from whether a sample met a laboratory limit.

ElectroSAnMBR should therefore keep protocols accessible, report exceptions alongside favourable results, and distinguish measured performance from projected full-scale behaviour. A promising result can still expose unresolved questions about fouling or waste handling. Recording those gaps is more valuable than allowing a laboratory certificate to stand in for shipboard confidence.

Working within class and flag-state frameworks

Classification societies do not certify an experimental concept in the abstract. They assess particular equipment, arrangements and evidence against applicable class rules and the wider statutory framework. Flag-state requirements remain part of the picture, so a credible engagement route must connect researchers, surveyors, shipowners and the vessel’s certification pathway.

A useful first meeting can map the intended duty, relevant rules, required test conditions and the boundary between laboratory evidence and onboard demonstration. Surveyors can then review sampling, calibration and quality-assurance plans before a pilot, while owners identify which approvals would apply to the vessel. The project can record these points without suggesting that participation guarantees approval.

International exchange adds useful perspective. Technical discussions connected with AD 14 Chile can help the project compare approaches beyond its immediate European network and identify questions worth raising with a wider range of maritime specialists. Comparisons remain strongest when they use verified test methods rather than broad claims about national performance.

Australian conditions shape the conversation

Australia’s regulatory setting makes compliance central to these conversations. The Australian Maritime Safety Authority administers domestic ship-pollution controls under the National Environment Protection (Ship Pollution) Act 2012, while ships on international voyages remain subject to MARPOL. Owners, class representatives and the research team can use this framework to define what a demonstration must demonstrate.

Power demand and carbon impact also belong in early discussions, not only at the end of a study. The project’s carbon footprint comparison provides a basis for checking electricity, methane and system-boundary assumptions against conventional bilge-water treatment. The result should support scrutiny of trade-offs rather than serve as a promotional claim.

Australian operating conditions sharpen those trade-offs. A vessel calling at Fremantle, carrying bulk cargo from Newcastle or managed from Melbourne needs a maintenance plan supported by nearby technicians and spare parts, not a promise of specialist support overseas. Plain-language protocols, realistic crew tasks and clear documentation are more persuasive to local technical teams than an elaborate slide deck.

Two practical participation pathways

The project’s engagement can be practical without becoming a paper exercise. Two routes are particularly useful, with the same discipline applied to commercial operators and independent reviewers. Participants should agree scope, confidentiality, decision points and who can act on the feedback.

For ship owners, ship managers and technical delegates:

• Appoint a maritime or environmental engineering liaison to represent operational and commercial priorities.
• Share a representative bilge-water profile, where available, covering oils, detergents, salinity, temperature and discharge patterns.
• Define non-negotiable constraints for footprint, power, maintenance access, crew training and certification.
• Review draft test methods and interim results through a joint call involving process engineers and vessel representatives.
• Coordinate with the nominated class surveyor and flag-state contacts so the feedback loop reflects the approval pathway.

For classification societies and surveyors:

• Hold an early technical meeting to identify applicable class rules, likely evidence gaps and relevant statutory interfaces.
• Review sampling frequency, calibration, quality assurance and the need for independent verification before trials begin.
• Clarify how the proposed arrangement relates to existing oily-water treatment and discharge-control requirements.
• Set out installation, commissioning and documentation expectations for a later shipboard demonstration.
• Nominate a contact to assess results, request corrective work and communicate material findings to the wider organisation.

Used together, these routes create a shared evidence record: agreed objectives, test protocols, operating notes, data logs and decisions. Owners gain a clearer view of suitability; reviewers gain early access to technical limitations; and ElectroSAnMBR receives the practical feedback needed to improve its reactor before wider use.

A shared path towards shipboard confidence

Successful engagement benefits all three groups. Ship owners gain evidence for investment and retrofit decisions, classification societies gain visibility of how a novel process behaves under realistic conditions, and researchers gain a firmer understanding of shipboard constraints. Independent review remains essential: participation is an exchange of evidence, not an endorsement.

ElectroSAnMBR invites ship owners, technical managers, naval architects and classification-society representatives to contact the research team to request a technical briefing, submit operating requirements or discuss a pilot opportunity. The team can then connect each request with the relevant experimental work package and agree the evidence needed for the next decision.

That approach turns European Union Horizon 2020 research into a practical path towards credible shipboard treatment, with decisions grounded in measured performance, clear responsibilities and operational experience.
