The Numbers Behind a Decade-Long Hull.
SEA-SPEED V 10 X ULTRA is not just a better coating — it is one of the highest-return efficiency investments on the ship. This is the fleet-economics and compliance case: the modelled ROI, the three pools of value behind it, the regulatory exposure it removes, and the framework we bring to the decision.
A coating that pays for itself — many times over
SepcoTech's performance model for a representative vessel. The fuel and emissions a smooth hull saves turn the coating into one of the highest-return efficiency investments on the ship.

10-Year analysis
Illustrative 5- and 10-year performance model for a representative vessel, at a 3% discount rate — actual figures depend on vessel type, operating profile, fuel price and route. Three pools of value drive the return: fuel savings, avoided drydock & recoat cost, and a single amortised system cost. Full assumptions available on request; request a tailored analysis on your own vessel particulars below.
Three categories of value in one decision
The ROI is not a single lever. SEA-SPEED improves the fuel bill, the maintenance plan and the regulatory position at the same time — and the three compound.
→ A saving you keep for a decade
4–12% fuel saving, verified across Ro-Ro, container, tanker and cruise. Because the film is non-depleting and groomable, that saving is held throughout the 10-year life — not a year-one number that fades as the coating wears.
→ One system, fewer haul-outs
One application, one 10-year warranted system — at least one recoat cycle removed at drydock, and fewer unplanned haul-outs. Drydock is scheduled on your terms, not dictated by a coating that is running out.
→ Better placed on every axis
~17% CII improvement verified, and zero biocide exposure on a tightening regulatory horizon. EU ETS, IMO CII and EEXI all move the same way — a smoother, biocide-free hull improves your position across all three at once.
The biocide question is a balance-sheet issue
Copper- and zinc-based antifoulings are under active regulatory review in multiple jurisdictions. On a 10-year hull-maintenance horizon, a change in port-state rules is not a remote risk — it is a planning assumption.
Biocidal Products Regulation under revision
The EU BPR is in active evaluation — a public Call for Evidence ran into early 2026, with a revised legislative proposal due in 2027. Zinc pyrithione is under review and copper pyrithione (used in roughly half of antifouling products) is next in line; Denmark already restricts biocidal antifouling. The direction of travel is clearly towards tighter controls.
Vessel Incidental Discharge Act
Under the EPA's VIDA national standards (finalised 2024), discharging copper-based coating residue — or in-water cleaning without capturing it — is prohibited in copper-impaired waters within the first 365 days after application. The EPA has previously acted to restrict TBT, and West Coast states already apply stricter local requirements.
Clean-hull biosecurity rules
New Zealand requires a clean hull on arrival and restricts in-water cleaning to approved providers; Australia mandates proactive biofouling management reporting. Non-compliance risks costly delay or denial of entry. A biocide-free, groomable foul-release hull is the easiest way to stay continuously clean and compliant on these routes.
How to evaluate this investment
We bring a four-point framework to the conversation — so the decision is made on your vessel's numbers, not a brochure.
Vessel-specific NPV model
We prepare this at no cost — coating cost, fuel savings, drydock avoidance and CO₂ value, modelled on your hull and operating profile.
Regulatory exposure assessment
Your current coating's biocide content set against the regulatory trajectory in the areas you actually trade.
CII trajectory impact
Modelled CII improvement and what it means for your EU ETS cost and IMO compliance position over the coating's life.
