Ultrasonic Thickness Measurement for Ships in La Spezia

Inspection services for ships at La Spezia

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

Where thickness gauging happens around the Gulf of La Spezia

Container gauging is done alongside at the La Spezia Container Terminal, with the scope agreed in advance and the work fitted around cargo cranes and lashing gangs. Ballast tanks that the chief officer can make safe, the hatch covers and coamings once lids are moved, and the scrubber system's pipework and shell outlets are the usual targets. A typical container call leaves room for a meaningful block of readings, and a liner ship that returns every few weeks can be gauged in stages until the survey requirement is covered.

At Panigaglia the work is governed by the LNG terminal's safety rules and the ship's own procedures, and is planned with the master and the operator before arrival. Cruise berths in the city give access during turnaround days, when passengers are ashore and technical spaces are quieter. Marina di Carrara's multipurpose quays, within the same port system, add heavy-lift and general cargo ships. Ships at anchor in the gulf are reached by a launch arranged by the agent, which is the usual route for pre-purchase and on-hire condition gauging, and for owners' inspections before a ship enters a charter.

• La Spezia Container Terminal — gauging of ballast tanks, hatch covers, coamings and scrubber overboard piping on container ships within the cargo window
• Panigaglia LNG terminal — ballast tank, inner hull, deck and deck piping gauging on LNG carriers during discharge, under terminal and ship permit systems
• Cruise berths, La Spezia — while passengers are ashore for the Cinque Terre, scrubber pipework and technical void spaces can be gauged
• Marina di Carrara — hold, tank top and hatch cover gauging on multipurpose and heavy-lift ships loading marble and project cargo
• Anchorage areas in and off the Gulf of La Spezia — calm-water launch access for buyers' and charterers' condition surveys, booked through the ship's agent

Regulatory and commercial context for ships in La Spezia

La Spezia applies the Paris MoU regime, and a ship's risk profile under it sets how often port state control officers board. The Mediterranean SOx ECA took effect on 1 May 2025; in the Ligurian Sea, as elsewhere within it, ships now need 0.10% sulphur fuel or a scrubber that achieves an equivalent sulphur oxide output. For large container ships on deep-sea services, many of them scrubber-fitted, that has turned the scrubber from an option used outside emission control areas into equipment running throughout the Mediterranean leg, and the corrosion of wash-water and overboard piping that comes with it into a planned inspection item.

LNG carriers bring their own regime. Their hull surveys follow IACS UR Z7 rather than the ESP rules, and the readings a superintendent wants during a call usually concern ballast tanks and inner hull, where coating breakdown begins. The container ships, LNG carriers and cruise ships calling here are within EU ETS, which has included shipping since 2024, and FuelEU Maritime, applicable from 2025, and these rules influence which older ships owners keep on European services; a current gauging record supports that decision. The gulf's naval and yacht yards give the area deep marine engineering expertise, even though commercial dockings are usually booked elsewhere.

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

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

Pisa International Airport and Genoa Cristoforo Colombo Airport are the nearest airports, with wider long-haul connections through Milan or Rome and a direct rail line into La Spezia. The ship's agent arranges ISPS passes for the container and cruise terminals and coordinates clearance for the Panigaglia LNG terminal, where access rules are strict. The technicians, all Indian nationals, need Schengen visas for Italy. If the enquiry arrives as soon as the call is fixed, there is normally time to align visas and flights; for a liner ship, planning around its regular rotation is simpler still.

• 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.
