Fleet Manager · SepcoTech

A hull that degrades between drydocks isn't a given. It's a choice.

Most fleet operators accept hull fouling as inevitable — a tax on performance you pay until the next drydock. That assumption is costing you fuel, CII rating and operational margin every single day.

SEA-SPEED V 10 X ULTRA — hard-film foul release, 10-year warranty, unlimited underwater grooming without film loss. Your hull performs on day 3,600 as it did on day one.

Live Demonstration

45 days fouled — cleaned in minutes.

Singapore field test: panels fouled for 45 days in tropical harbour conditions, then groomed by ROV. Watch how Sea-Speed releases fouling — completely — with zero chemical release and no film loss.

Singapore harbour immersion test — 45 days. ROV grooming. Zero toxic release. Zero film loss.

The Shift

Three things fleet managers are told are unavoidable. They're not.

Sea-Speed doesn't ask you to accept less performance between drydocks — it changes the terms entirely.

The assumption

"Performance drops between drydocks — that's just how hulls work."

The reality

Unlimited underwater grooming resets hull performance to day-one condition — every time, without dry dock.

The assumption

"You need biocides to keep a hull clean — there's no other way."

The reality

Sea-Speed releases fouling through surface chemistry alone. No biocides, no depletion, no regulatory exposure.

The assumption

"Recoating every 3–5 years is a fixed maintenance cost."

The reality

One application. Ten-year warranty. One set of costs — spread over the entire decade.

Between-Drydock Performance

What changes when your hull stays clean.

Conventional antifouling degrades from the moment it enters the water. Sea-Speed is a different class of system — designed to be groomed, not consumed.

Fuel savings maintained

Sub-20µ surface roughness maintained over 10 years — through grooming, not ablation. Fuel savings don't diminish in year 4 or year 8.

📊

CII rating protected

17% CII improvement verified in year one. Regular underwater grooming keeps the hull at peak efficiency — protecting your CII trajectory between drydocks.

🔧

Drydock interval extended

A 10-year warranted system means you schedule drydock on your terms — not around a coating that's running out. Fewer unplanned haul-outs.

The Technology

Why Sea-Speed can be groomed 1,000+ times.

Conventional ablative antifouling is gradually consumed — every cleaning removes coating. Sea-Speed is a non-depleting hard film. Grooming removes fouling, not coating.

  • Hard-film Silane-Siloxane — not ablative; not depleting; coating preserved over 10 years
  • <20µ Rz surface roughness — nano-smooth and maintained by regular grooming
  • Fouling adhesion near zero — barnacles wipe off by hand after 18 weeks static immersion
  • Zero biocides — grooming releases nothing toxic; compliant in all ports worldwide
  • Lloyd's Register certified — independent third-party verification of all performance claims
  • 400+ US Navy vessels — in service since 2001; proven in the most demanding operational conditions

Financial Performance

The numbers behind the decision.

Hull coating is a capital allocation decision. The 10-year model covers coating cost, fuel savings, reduced drydock frequency and CO₂ reduction.

What operators say

Proof from the people who run the vessels.

We are seeing 2–3% decrease in consumption at 21 knots and a 5–7% improvement at 15–17 knots. This equates to a 17% improvement in our Carbon Intensity Index between 2021 and 2022.
Joey HalversonDirector of Ship Management, TOTE Services LLC — December 2022
Sea-Speed V 10 X ULTRA exceeds environmental regulations globally for all types of vessels. The technology is highly advanced from both a technical and functional viewpoint. It has a phenomenal future in the maritime industry.
