Ship Steel Condition Surveys in Chioggia, Southern Venice Lagoon

Inspection services for ships at Chioggia

Each service has its own page with the method, the class requirements and what the report contains.

Where gauging happens in Chioggia: quays, lay-by berths and the lagoon yards

Gauging on small cargo ships takes place alongside at the commercial quays during or after cargo operations, with holds measured once empty and safe for entry. Because the ships are small, a team can often cover holds, deck, hatch covers and an accessible group of ballast tanks in a single day. For fishing vessels, the best time is when the boat is tied up in the canal between trips or laid up for the closed season, with the crew preparing the bilges and the hold areas beforehand so that the plating is clean enough for readings.

Lagoon yards in and around the town can lift or slip small hulls, which gives access to the bottom plating of fishing boats, tugs and workboats. These yards do not take large merchant ships, so a coaster needing a renewal survey docks elsewhere on the Adriatic, for example at Venice-area yards, Ravenna or on the Croatian coast, and a thickness survey in Chioggia beforehand helps that yard plan steel renewal. Ships waiting for a berth or the tide may anchor off the inlet, where a limited condition check is possible in calm conditions.

• Commercial quays — hold frames, tank tops, hatch covers and coamings on coasters and small bulk carriers after discharge
• Fishing canal berths — hull plating, bilges and fish hold structure of steel fishing vessels tied up between trips
• Lagoon yards and slipways — bottom and shell plating of tugs, fishing boats and workboats when hauled out
• Lay-by berths — owner's condition checks on ships laid up or awaiting sale or employment
• Anchorage off the inlet — limited condition checks on ships waiting for a berth, by launch through the ship's agent

Port state control and regulation for small ships and fishing craft in Chioggia

Port state control applies to foreign-flag cargo ships in Chioggia, exercised by the Italian Coast Guard through the harbour master (Capitaneria di Porto) under the Paris MoU, and older coasters tend to attract more attention because of their ship risk profile. Fishing vessels fall under separate flag state and fisheries safety rules rather than the Paris MoU, and many are not classed, so thickness records are usually requested by insurers, lenders or buyers rather than by a surveyor. For classed small ships, the society sets which readings each renewal or intermediate survey needs.

Wider rules touch this market in several ways. The EU Ship Recycling Regulation requires an Inventory of Hazardous Materials on ships calling at EU ports, and the owners of old coasters who are considering sale or scrapping use gauging records to judge the remaining value of the steel. EU ETS and FuelEU Maritime affect cargo ships but not fishing boats, and fleet renewal programmes for fishing vessels, supported by regional funds, can bring a wave of surveys when owners consider replacement or major repair. Environmental protection in the lagoon also limits the scope of cleaning work near the water.

Since 1 May 2025 the whole Mediterranean has been a sulphur emission control area, so ships calling at Chioggia burn 0.10% sulphur fuel or run a scrubber. Scrubber wash-water piping, the overboard discharge and the hull penetration around it corrode quickly in service and are worth adding to the gauging scope at every docking.

How a thickness measurement job runs at Chioggia

Most of the work on a Chioggia job happens before the team boards: scope, plan and access are settled first, so the time on board goes on measurement.

Venice Marco Polo Airport is the usual entry point and is connected to Chioggia by road, while Treviso and Bologna offer further options. The ship's agent, or the owner where a vessel has no agent, arranges port access and any launch for anchorage work. Our technicians are Indian nationals travelling on Schengen visas, so we start the application when the job is confirmed and book flights once the ship's schedule or the boat's availability in Chioggia is firm. Combining Chioggia with Venice or Ravenna in one trip often makes sense for the team.

• Send the vessel name or IMO number, ship type, class society, the survey due (annual, intermediate, renewal survey number, CAP or owner's condition survey), the port and dates, and the scope you expect.
• We confirm the scope against the class rules for that survey, prepare the thickness measurement plan with frame and section references, and say whether the measurement will be credited to a class survey.
• Mobilisation is planned around visa lead times and the vessel's schedule; the ship's agent arranges port access, and the yard or ship arranges staging, lighting, ventilation and gas-free certificates.
• Gauging with calibrated ultrasonic thickness gauges: through sound coatings only where the gauge's through-coating mode has been verified on a coated reference, otherwise on cleaned bare steel, with every reading tied to its frame, strake and location on the sketch.
• Readings are compared with original thicknesses as work proceeds; substantial and excessive corrosion and any cracks are reported to the attending surveyor and the superintendent the same day.
• The final report is issued on the class thickness-measurement formats with sketches, a summary of locations exceeding the allowable margins, piping tables where piping was in scope, and the gauge calibration and technician certificates.
