The Checks a Fleet Lives By: Proven, Not Assumed
Tankers, bulkers, container, RoRo and gas carriers all depend on the same invisible things: that compartments seal, that fire cylinders are full, and that the steel is still thick enough. Coltraco's non-invasive instruments let the crew prove each one, with one operator, a number on a screen, and a logged result for class and port-state inspection.
Four passive systems, all silent until they fail
A leaking hatch seal, a slowly emptying CO2 cylinder, a dropping inert-gas pressure and a wasting bulkhead share one dangerous trait: none of them shows on a walk-round, and none announces itself until the moment it matters. According to Allianz's Safety & Shipping Review 2023, fire was the second-leading cause of large-ship total loss in 2022, after foundering, which is overwhelmingly driven by water ingress. These are exactly the two failure modes a commercial fleet spends its survey budget guarding against.
Coltraco's ultrasonic instruments turn each of those invisible risks into a number the crew can read and log, without flooding tests, cylinder removal, hot-work permits or a dockyard. SepcoTech supplies and supports the full range, with calibration and spares from one partner.
- Single-operator handhelds: checks that actually get done on schedule
- Non-invasive: nothing opened, drained, discharged or taken offline
- Logged, repeatable readings that provide evidence for class and port-state inspection
- One supplier for instrument, calibration, spares and technical advice
The Coltraco Instruments a Commercial Fleet Specifies
Four jobs, four instruments: each links through to full specifications, the brochure and the quote builder.
Watertight & Hatch Covers
Portascanner® WATERTIGHT PLUS / PRO proves watertight doors, hatch covers and cable transits truly seal, down to a 0.06 mm aperture. The check against wet-cargo and water-damage claims.

Fire-Cylinder Charge
Portalevel® + Portasteele® confirm CO2, FM-200® and NOVEC™ 1230 cylinders are full through the wall in under 30 seconds, system armed, no weighing.
View level indicators →
Inert-Gas Pressure
Portagas® provides non-invasive pressure monitoring of inert-gas fire systems (Inergen, nitrogen, argon) to better than the 5% the standards demand, with no gauge break-in.

Hull & Structural Thickness
Portagauge® 6 gives multi-echo measurement of true metal thickness through coatings, for hull, bulkhead and pipework corrosion surveys, with a 200,000-reading data logger.

Flow & Bunkering
Portasonic® / Permaflow® deliver clamp-on transit-time flow measurement for fuel transfers, bunkering and cooling-water lines, with no pipe-cutting and no shutdown.

The Regimes These Readings Support
Each instrument produces logged, repeatable evidence against the regulations a commercial fleet already works to.
Watertight Doors
IMO SOLAS Reg II-1/21.3 requires watertight doors to be inspected at least weekly at sea. The Portascanner logs each result.
Hatch Covers & Transits
IACS UR Z17 / DNVGL-CP-0484 for hatch-cover weathertightness, and IACS UR Z28 for multi-cable-transit registers (vessels contracted after 1 Jul 2021).
Fixed Gas Fire Systems
SOLAS FSS Code (Chapter 5) and IMO MSC.1/Circ.1318/Rev.1 require fire cylinders to be verified at ≥90% charge at least every two years.
Structural Thickness
Hull, bulkhead and pipework wastage measured to your classification society's survey regime, through coatings, so the same point is re-read each survey.
Aboard tankers, bulkers and gas carriers worldwide
Coltraco reports its instruments aboard roughly 17% of the world's ~60,000 ships, present on gas carriers, bulk carriers, oil tankers and chemical/product carriers, and used by leading ship managers and owners including A.P. Møller–Maersk, Hapag-Lloyd, V.Ships, BP Shipping, Wallem, Thome and Synergy Marine.
★★★★★“The fleet was equipped with a unit per bulk carrier and the units are working well, providing the confidence that there will be no problems with water-damage claims.”
