Gioia Tauro: Ultrasonic Gauging for Transhipment Container Ships and Carriers

Inspection services for ships at Gioia Tauro

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

Where thickness gauging can be done at Gioia Tauro

Gioia Tauro is a cargo port with no major drydock, and ships needing a docking survey normally continue to a repair yard elsewhere in southern Italy, in Sicily, or to Malta or Naples. The port's value for thickness measurement is the berth. Ships lie at the container quays for the time cargo handling requires, and within that time a limited programme can be completed: hatch coamings and covers, selected ballast tanks that the crew has emptied and ventilated, upper deck plating and, where the stow allows, parts of the hull side accessible from the quay.

Where a ship is waiting for orders at the anchorage, or has been laid up, a launch from the agent can take the team out, though the extent of work depends on the weather and on tanks being gas-free and safe to enter. For ships heading to a yard, readings at Gioia Tauro help the owner set an early steel estimate. The nearby Strait of Messina ports, including Messina itself, have established repair facilities, and a mobilisation by road can cover ships there in the same trip.

• Container quays — hatch coaming, hatch cover and cell guide area gauging on container ships during the cargo operation
• Ballast tanks of transhipment ships — selected tanks emptied and ventilated by the crew, gauged between discharge and sailing
• Ro-ro and vehicle carrier berths — ramp, deck and hull side readings on carriers calling for vehicle cargo
• Reefer vessels — hull and deck readings on refrigerated cargo ships during port stays
• Anchorage off the port — owner's condition work on ships waiting for a berth or on lay-up, using a launch
• Messina and the Strait ports — repair yards and layover berths reachable by road, often joined to a Gioia Tauro mobilisation

Port state control, container-ship structure and the Calabrian setting

Ships calling at Gioia Tauro come under Paris MoU port state control, carried out by the Italian Coast Guard, the Guardia Costiera. Container ships are rarely selected for structural reasons alone, but older tonnage on regional feeder services is more exposed, and any structural deficiency recorded in one Italian port will follow a ship to the next. Container ships raise specific structural questions: hatch coaming cracking and wastage, corrosion in ballast tanks adjacent to heated fuel tanks, and fatigue at hatch corners. Thickness records are a practical way to document that a ship is within limits before an inspection occurs.

EU rules add pressure. The Ship Recycling Regulation requires an Inventory of Hazardous Materials for ships calling at EU ports, and EU ETS and FuelEU Maritime apply to the large container ships that make up much of Gioia Tauro's traffic. For owners of older container tonnage, the choice between renewing steel and retiring the ship is increasingly sensitive to emissions rules, and measured thickness provides a sound basis for that decision. Short stops in a hub port are a useful chance to collect this data without disrupting the liner schedule.

Since 1 May 2025 the whole Mediterranean has been a sulphur emission control area, so ships calling at Gioia Tauro 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 Gioia Tauro

The sequence for a thickness measurement job at Gioia Tauro is short and written down, so the yard, the surveyor and the superintendent know who arranges what.

Lamezia Terme is the nearest commercial airport, with Reggio Calabria also within reach, and Naples or Catania serve as wider gateways; the port is reached by road. The ship's agent arranges the access passes required at the container terminal, which has strict security procedures, and books a launch for ships at the anchorage. The team travels from India and needs Schengen visas, so confirm the ship's expected call early and allow time for visa processing.

• 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.
