Your water gets a program of its own.
You subscribe to an outcome: defined improvements inside a defined service zone, with parameters settled in writing between you, the operating company and the consenting authority before a hull is committed. A licensed service operator then holds the water to them every month of the year. The systems are deployed as a service and are neither sold nor rented, and there is no number to ring, because the crew is already in your zone.
The sequence
Four stages, and you can stop after any of them.
- Situation report You send the water body, the stressor, the season and the cost. A description is enough. It goes to Alarivean through the contact form and takes about ten minutes.
- Site read The operator comes back with what the available data says about that water: what is likely driving the deficit, whether this platform is the right instrument, what a realistic service zone looks like, and where the uncertainty sits. Sometimes that means you need a different tool.
- Calibration phase A bounded demonstration area with agreed viability parameters, run on your own water. Both parties see what happens before either commits to a program, including the contained throughput each hull sustains: specified for a hull of this class at approximately 5,000 gallons a minute, then measured against the baseline taken beforehand. That is a rate of flow through the reactor. The water goes back on the same pass, and nothing accumulates aboard.
- Service zone The subscription itself, with no off season. Vessels on the program every month, gases and augments included, proactive protection and Deep Strikes on forming water outside the zone as standard, telemetry and reporting throughout. Before anything is contracted, the zone is baselined against its own stratification, flushing time and event record, and the agreed outcomes are measured from that baseline.
Running across all four
Independent scientific oversight, for the whole of it.
Oversight is one of the four pillars a program is built on, alongside the vessels, the gas supply and the telemetry.
Local scientific expertise is engaged from the situation report onward and for as long as the subscription runs: a marine institute, a fisheries laboratory, an estuary body, a ministry's own scientists — whoever already answers for that water.
Risk control runs to best practice on that basis, with human and environmental health and safety ranked above the program's own targets. Where those pull against each other, the oversight group is inside the decision.
Through the quiet months too
Present while decisions are still being made, in the bad months as well.
The feeds themselves
Live access to every water-quality feed the crews work from, plus any the oversight party brings.
Local, because local is accountable
Institutions answerable in that place, to that public, long after a contract ends.
Two copies of the record
Somebody outside the operating company can reconstruct any month of the program without asking it first.
What is in the base
Everything the vessel needs to work, and no part of it your problem.
A full service program keeps SeaBreather vessels on that water all year, with all gases and natural augments for coastal quality improvement inside the subscription.
The base subscription covers proactive service-zone protection and Deep Strikes outside it, intercepting an event where it is forming, along your shoreline or a good way off it, before it arrives as yours.
Off your side of the table: gas procurement and logistics, vessel capital, crew, instrumentation, the analytics stack, and the internal argument about which department owns the boat.
Still on it: the upstream nutrient problem, the permitting relationship with your own regulator, and a straight account of what the water has been doing.
No two programs match. A water column moves, and so do the regulatory, political and economic conditions around it, so a program is written to one zone and does not transfer whole. What the operating company owes you is a standard of water held across the year, measured against the baseline that zone started from.

Why it never stops
Oxygen demand does not stop in October.
There are stressors working on a coastal water body at any given hour. Running full time keeps a program in front of what they add up to.
Organic material settles and decomposes in every month. Water warms and holds less. A column stops turning over. Whatever the catchment sent down in March is still being worked on in June. August is only when the arithmetic becomes visible.
A deficit held down continuously never reaches the state that needs an expensive emergency, so the zone meets its hardest weeks already ahead.
The exposure behind that arithmetic is larger than a harvest. From 1 November 2025 South Australia restricted commercial marine scalefish and blue crab fishing across the zone PIRSA names for Gulf St Vincent and Kangaroo Island, an expectation carried out to 30 June 2026 and reviewed against the science as it arrived. Spencer Gulf was untouched. The South Australian and Federal Governments have committed more than A$160 million to the response, the figure on the state's algal bloom page when read on 9 September 2026. That is money spent answering the event, which differs from what the event took. Neither the restriction nor the spending says what any vessel program would have changed there.
Standing means hulls already inside the zone, a consent already issued by the authority that governs it, crews accredited to that regulator, and gas arriving on a schedule set months earlier. None of it can be conjured on the morning something arrives.
It does not mean a hull parked in one bay forever. A given week follows the water, the readings and the forecast.
The economics
An ounce of prevention is worth a pound of cure. It is why this can be offered at the value it is.
Bought as a purely reactionary force — idle until called, then mobilized against a stressor that has already accumulated — the same competence would cost very much more. It would have to cover the waiting, the short notice and the size of the job that waiting created.
How a subscription ends
Two grounds. Performance outside the specification written for your water ends it at any point in the term.
And once the minimum subscription period has been served, a client who is not satisfied ends it for any reason, or none stated.
Very few infrastructure contracts carry the second one.
Commercial structure
Sovereign programs are built differently from port contracts.
At national scale there is no single form; which fits is a question for the jurisdiction and the client. A licensed operating company can hold the whole thing. It can run through a joint venture, with the client or a local partner. Or the systems can be licensed from Sophia Delta, with or without a venture beside that license. Where a jurisdiction prefers the majority held at home, the shape carries that; where it does not, nothing asks for it. An industrial gas partner with regional supply sits in most versions, because supply on a long coastline is a logistics problem first.
Whichever shape it takes, the platform is provided as a service and never sold or rented. A license and a revenue share are arrangements between the delivering companies; neither lets a client own or hire a machine. Signing reserves no stretch of coast. A zone certified against the licensed systems and running to its terms belongs to whoever runs it, for as long as they run it properly.
At asset scale — a port, a plant, a resort group, a fish farm — it is a subscription with a zone and a set of upgrades, running until one of the two grounds ends it. No joint venture, no license, no five-year architecture. The technical work is the same at either end.
Before you write
Price, exit, reports, calibration, speed
What drives the price, and when does a figure arrive?
Zone area, vessel tier, gas supply, instrumentation, the oversight arrangement, and the permitting work in your own jurisdiction. A subscription is priced against a volume of water and a distance from a working port, and both vary by more than an order of magnitude between sites.
Prevention decides the order of magnitude: a deficit held down week by week stays routine work, priced far below a response mobilized against it at full size.
The figure for your water arrives with the site read, in writing, with its assumptions printed. Fixed before that: the shape of the commercial structure, what sits in the base, and what counts as an upgrade.
On what grounds can we end the subscription?
Two. Performance outside the specification written for your water, at any point in the term. Or, once the minimum subscription period has been served, simple dissatisfaction, with any reason or none.
No fault to establish and no threshold of severity.
What actually goes in a situation report?
The water body and roughly where. What goes wrong, and in which months. What it costs when it goes wrong — lost harvest, throttled plant, closed beach, canceled bookings, remediation spend. Anything you have already tried.
Depth profiles and water-quality history help if you have them. If you do not, send it anyway.
What happens if the calibration phase misses its parameters?
The phase closes and no program is committed. Viability parameters are agreed with you and your regulator in writing before a vessel arrives, so the meaning of a miss is settled in advance.
The institution holding the live feeds sees the same numbers at the same moment the crew does, and its fee does not move with the reading.
How quickly can a vessel be in the water?
Standing a program up from cold takes regional fleet availability, your own permitting, gas supply and crew accreditation. That work runs in weeks. A stressor runs in days.
On a live subscription all of it is already inside the zone and working. Consents, accreditation and gas logistics do not move faster because a bloom has arrived.
