Subsea pipeline integrity · edge-first detection
Covtura Nexus fuses pressure and acoustic telemetry to catch a subsea release the second it starts, pinpoints it to the kilometre post, and puts a defensible cost on it — running on the seabed edge, with or without a link to shore.
The stakes
Surface sheen, a pressure engineer's hunch, a scheduled ROV pass still weeks out — the ways subsea leaks usually surface are the ways they become spills. Every hour between release and response is barrels in the water, regulators at the gate, and liability compounding.
Conventional detection reacts to symptoms downstream. By the time the signal is unambiguous, a containable event has become a reportable one.
Offshore connectivity drops. Cloud-dependent monitoring goes quiet exactly where and when the pipeline needs watching most.
Without a tamper-evident timeline, every regulator inquiry and insurance claim starts from a blank page — and your word against theirs.
How it works
Four stages, one incident record. Each event moves through the same path — so nothing is caught without being located, verified, and costed.
A pressure drop alone is a warning. A pressure drop and an acoustic signature inside the same ten-second window is a critical. Two independent physics, one verdict — so real releases raise the alarm and noise doesn't.
The same event reaches two sensors microseconds apart. Covtura solves for the source against the fluid's real wavespeed to place it on the line — a kilometre post, a coordinate, a depth — not a segment-wide guess.
x = (L + c · Δt) / 2The event opens an incident and a dispatch package: acknowledge, send an ROV, log the on-site finding, and drive the incident through a single append-only lifecycle from detected to resolved.
Every confirmed incident writes to a hash-chained exposure ledger — duration × tier rate × escalation, in exact decimal — so your financial position is current the moment the event is, not at quarter close.
Why edge-first
Offshore links drop. Detection can't. Covtura's edge nodes run the full threshold-and-fusion engine on the seabed side of the connection — they alarm locally with zero reachability to shore, buffer every reading, and replay it exactly once when the link returns.
The platform
Detection is the wedge. What operators keep is the console around it — live, verifiable, and built for audit from the first row.
Real telemetry and KP-located events, sub-second from seabed to your glass. A live stream of the pipeline as it is now — no mock feeds, no polling.
Turn an alarm into a mission: dispatch package, on-site status, and an auto-closing verification — all on the one incident record.
Jurisdiction-aware notification drafts with the clock already running against your reporting deadline. NOSDRA pack included.
Append-only, hash-chained, decimal-exact liability — the number your finance and insurance teams can stand behind.
Every record scoped to its operator and enforced in the database by row-level security. One platform, many assets, no bleed between them.
Every incident exports an evidence pack — timeline, chain, artefacts — verifiable end to end by SHA-256.
Under the hood
The rules a pipeline engineer will ask about — stated plainly, because vague is expensive.
How we start
No fleet-wide commitment to find out if it works. A scoped path that earns the next step at each stage.
A live walkthrough — watch a fracture become a located, costed, verifiable incident in one sitting.
A single pipeline segment on a scoped paid pilot. Your data, your thresholds, your regulators — proven against your own asset.
Roll out across assets on the same multi-tenant platform once the segment has made the case for you.
