Hull Performance & Inspection — Hamburg, Germany
Know Your Hull
Before Fouling Costs You Fuel.
We partner with Vesselity to bring shipowners a data-driven hull-performance platform and a certified, diver-free micro-ROV inspection service. The software predicts where fouling is building; the ROV proves what is really on the hull. Run them as one loop — or use either on its own.
Software That Predicts. Inspection That Proves.
Vesselity is built around two complementary services. One watches your fleet's fouling risk from your operating data. The other goes underwater to confirm the true condition of the hull. They are designed to work as a single loop — but each delivers value entirely on its own.
Hull-Sight — Fouling Analytics Software
A cloud platform that turns routing, water temperature, biology, and speed into a clear, ship-by-ship fouling-risk picture — and stores every underwater inspection in one place with automated reporting and AI image analysis. Stop scheduling cleaning by the calendar and start scheduling it on data.

Micro-ROV Inspection — Certified IWS
A diver-free hull inspection service flown with a 9 kg micro-ROV — from a quay, an anchorage, or the vessel itself. AI image segmentation classifies biofouling and coating damage at over 98% accuracy, and the survey can be delivered to certified In-Water Survey (IWS) standard.

Within hours of entering the water a hull begins to collect a biofilm. Left unchecked, algae, barnacles, and tubeworms follow — and the drag they add forces the engine to burn more fuel for the same speed. Invisible from the deck, it shows up in every fuel bill and emissions report.
20–25% Emissions
A biofilm of just 0.5 mm across half a hull can lift greenhouse-gas emissions by a fifth or more — and light barnacle growth can push fuel use far higher still.
~90 Mt CO₂ / Year
Industry estimates put the fuel wasted fighting fouling drag at roughly 10% of all shipping fuel — around 90 million tonnes of avoidable CO₂ every year.
>7% Fuel Saved
Proactive, evidence-based hull cleaning can recover well over 7% in fuel consumption — money and carbon that simply leak away when fouling goes unmeasured.
CII Compliance
Since the IMO's Carbon Intensity Indicator took effect in 2023, a fouled hull is no longer just costly — a poor rating can place real limits on how a vessel may trade.
A Closed Loop — From Prediction to Proof.
When the platform and the inspection service run together, each makes the other sharper. The software decides where to look; the ROV confirms what is really there; the findings feed back to make the next prediction more accurate.
Predict
Hull-Sight scores fouling risk for every vessel from its routes, speed, and the waters it has been sitting in — so you know which hulls to worry about first.
Inspect
A micro-ROV survey confirms the real condition underwater. AI segmentation measures fouling coverage and flags coating damage — no divers, no dry-docking.
Decide & Learn
Inspection results land back in Hull-Sight as an evidence record. Cleaning is scheduled on fact, and every survey makes the next risk model more accurate.
Strong Together. Solid Apart.
You do not have to adopt the whole loop on day one. The platform earns its keep simply by helping you stop guessing which vessels need attention. The inspection service stands alone as a faster, safer, cheaper alternative to a diver survey — with or without a subscription behind it.
- Software only — prioritise the fleet and manage inspection records from any browser
- Inspection only — book a single certified survey when a class deadline or fuel concern demands one
- Both together — the full predict-inspect-decide loop, with results compounding over time
Milestones, Not Marketing.
Vesselity's approach has already cleared the bar that matters most in shipping — independent class certification. Two milestones stand out.
A Class Survey Carried Out Entirely by ROV
In Puttgarden, Germany, Lloyd's Register awarded certification for an in-water survey conducted entirely by remotely operated vehicle — with no divers in the water.
"A landmark moment for classification and maritime digitalisation."— Lloyd's Register, on the remote ROV in-water survey
Scandlines' First Class Certificate Without Divers
Scandlines Germany received its first ROV class certificate achieved without conventional divers, using a 9 kg micro-ROV system — and reported savings compared with a conventional diver survey.
"50 percent and more costs saved compared to conventional divers."— Reported outcome, Scandlines Germany ROV survey
Case details as reported by Vesselity and partners. Certification was carried out by the respective classification society.
A Digital Edge,
Delivered Locally.
SepcoTech represents Vesselity across the Nordic and Baltic countries — Denmark, Norway, Sweden, Finland and Iceland, plus Estonia, Latvia and Lithuania. The platform and the inspection service are Vesselity's; our role is to bring them to your fleet — scoping the right starting point, coordinating surveys around your port calls, and putting the data to work in day-to-day decisions. And because Vesselity's inspections fly on the same 9 kg Blueye micro-ROV that SepcoTech supplies, the analytics, the service, and the hardware all come from one accountable partner.
- Single point of contact for software, inspection, and ROV hardware
- Local coordination — surveys planned around your schedules and port calls
- Class-aware — inspections delivered to certified In-Water Survey standard where required
- Outcome-focused — we lead with the fuel, emissions, and compliance result
- Same Blueye micro-ROV we distribute and support — hardware, service, and analytics from one partner
- Local-currency and EUR pricing — clear, regional, no hidden import costs
Every Vessel That Has a Hull Has a Hull-Performance Problem.
Fouling affects every vessel type that moves through the sea. Hull-Sight and the ROV inspection service are in active use — or directly applicable — across these segments.
Ferry & Ro-Ro Operators
Fixed routes and tight turnarounds mean every knot of extra drag costs money fast. Small fouling gains compound over thousands of crossings a year.
Tanker & Bulk Fleets
Long idle times in warm tropical anchorages accelerate fouling. CII compliance pressure makes fuel transparency essential — and hull condition is the biggest variable.
Container & Cargo Lines
Speed matters. Even a thin biofilm across a large hull adds drag that impacts on-time performance and carbon reporting. Hull-Sight makes the risk visible before it hits the schedule.
Offshore Support & Work Vessels
OSVs and PSVs spend significant time at anchor in warm, productive waters — exactly the conditions where fouling establishes fastest. ROV inspection fits naturally into port calls.
Naval & Government Fleets
Diver-free inspection removes personnel risk on defence vessels. Certified IWS surveys satisfy class requirements without compromising operational security or availability.
Cruise & Passenger Vessels
Large hull areas and environmental reporting obligations — ROV inspection in port satisfies class, provides evidence for efficiency claims, and avoids scheduling dry-dock.
Research & Survey Vessels
Operating in remote locations makes diver mobilisation difficult. A 9 kg ROV that one person can launch from the vessel itself changes what's possible between yard periods.
Ship Managers & Technical Operators
Managing hull health across a managed fleet — Hull-Sight's whole-fleet view and automated reporting mean one platform covers all vessels under management.
