Piombino Ship Gauging: Ultrasonic Thickness Readings for Ferries and Steel Carriers
Piombino faces Elba across a narrow channel on the Tuscan coast, and its quays serve a mixed fleet: island ferries, carriers loading and discharging steel products, bulk ships and, since 2023, a floating LNG terminal. A ship that needs thickness gauging here usually has a short window alongside, so Atlantis NDT sends an inspection team from India to the vessel and builds the scope around the berth plan, the ferry timetable and the surveyor's list.
Elba ferries on a tight rotation
Short crossings to Portoferraio and the other Elba landings mean a ferry spends only brief periods at the berth. Gauging here is planned in blocks of spaces, repeated over several calls, instead of one long shutdown.
Steel cargoes wear holds and hatch covers
Coils, billets, plate and scrap abrade tank tops and hold sides in ways that grain or container trades do not. Steel carriers calling at Piombino are good candidates for hold-by-hold gauging before a survey.
A port with several different trades
Passenger ferries, steel products, dry bulk and an LNG regasification vessel share one harbour, so a single mobilisation can cover ships with very different gauging scopes if the dates line up.

ExploreThe port of Piombino, its channel crossing and its steel trade
Piombino sits on the Tuscan coast roughly opposite Elba, with the Piombino Channel between the mainland and the island. The harbour is protected by breakwaters and is reached from the open Tyrrhenian without a river bar or lock, so there is no tidal gate to plan around and a ship can generally be worked as soon as it is alongside. Weather matters more than water level: the channel can be rough in strong southwesterly or northerly conditions, and ferries and small craft adjust their programmes accordingly. Because the port lies between Livorno to the north and the Rome and Naples ports to the south, ships often arrive here as one stop in a longer Tyrrhenian rotation.
The commercial identity of Piombino is steel. The town grew around its steelworks, and the port has long handled steel products, coils, plate, scrap and the raw materials that feed metal production. Ships carrying these cargoes are hard on their own structure: cargo is heavy, often dense and abrasive, and loading with grabs or cranes damages tank tops, hold ladders and lower hold plating. Carriers that regularly serve steel mills therefore show localised wastage in places that a renewal survey will want measured. The passenger side of the port is just as busy: ferries run to the Elba landings throughout the year and more heavily in summer, and some timetables extend to Sardinia and Corsica.
A newer element is energy. A floating storage and regasification ship was brought to Piombino in 2023 as part of Italy's response to changing gas supply, and LNG carriers call to supply it. That adds a class of high-value, tightly controlled ships to the port, although gauging on a gas ship is governed by the owner's and the terminal's safety rules and is limited to what can be done alongside. Together these trades give Piombino an unusual spread of hull types in a small harbour, which suits owners who want several ships looked at in one visit.
Where ships can be gauged in and around Piombino
Piombino is a working cargo and ferry port rather than a major repair centre. Alongside work is therefore the norm: ships are gauged at the commercial quays during a cargo stop, a ferry layover or a period waiting for berth, and the programme is limited to spaces that can be opened, ventilated and made safe in the time available. Cargo holds are the most practical target on bulk and steel carriers once discharge has finished and the hold has been swept, because the crew can make them accessible with ladders or a cherry picker, and the surveyor can see the same plating that is being measured.
Where a full docking is needed, ships from Piombino generally go to a larger repair yard elsewhere on the Tyrrhenian or in the wider Mediterranean, and pre-docking gauging at Piombino then helps the owner to set the steel work in advance. Livorno, in the same port system to the north, and Naples to the south are the usual reference points for owners deciding where to dock. Anchorage work is possible for ships waiting to berth or laid up, although it needs a launch and the weather window to match, and tanks must be gas-free before anyone enters.
- Commercial quays — alongside gauging of cargo holds, hatch coamings and tank tops on steel and bulk carriers between discharge and the next loading
- Elba ferry berths — blocks of vehicle deck, ramp structure and ballast tank readings taken over several turnarounds before a docking
- General cargo and project-cargo berths — hull and deck readings on ships that carry heavy steel items, where lashing and crane work have worn plating
- Berths used by the LNG regasification ship — limited exterior and accessible-space gauging on visiting ships, subject to the terminal's own safety regime
- Piombino roads — gauging of ships at anchor, in lay-up or waiting for a berth, with a launch arranged through the agent
- Livorno and Naples repair yards — drydock gauging for ships that leave Piombino for a docking, linked to the pre-docking readings taken at the berth
Thickness measurement through the survey cycle at Piombino
Every renewal survey asks for more thickness measurement than the last, and for oil tankers, chemical tankers and bulk carriers the ESP Code adds close-up survey on top. The table is the usual shape of the work; the class rules and the surveyor set the exact extent, which is why the measurement plan for a job at Piombino is agreed in writing before mobilisation.
| Survey | When it falls | What the thickness measurement usually covers |
|---|---|---|
| Annual survey | Every year, within three months of the anniversary date | General examination. Gauging where the surveyor finds suspect areas or where substantial corrosion was recorded at an earlier survey. |
| Intermediate survey | In place of the second or third annual survey | Suspect areas, and on older ships and ESP ships selected ballast and cargo spaces with close-up survey; the extent grows with age. |
| Renewal survey No. 1 | Around 5 years | The first full baseline: suspect areas and selected plating and stiffeners, usually with modest steel renewal. |
| Renewal survey No. 2 | Around 10 years | Wider gauging of deck, bottom and side plating, transverse sections across the cargo area on ESP ships, and more close-up survey. |
| Renewal survey No. 3 | Around 15 years | Extensive gauging of cargo and ballast tank structure and more transverse sections. The survey most likely to turn up steel renewal. |
| Renewal survey No. 4 and later | Around 20 and 25 years | Gauging extended to most structural members in cargo and ballast spaces. Charterers often add a Condition Assessment Programme. |
| Docking survey | Twice in each five-year period | Bottom and side shell, sea chests, rudder and stern area while the hull is dry; suspect bottom plating gauged. |
Port state control, the energy angle and Italian oversight
Foreign ships calling at Piombino are targeted for port state control under the Paris MoU, with inspections carried out by the Guardia Costiera, the Italian Coast Guard, through its local harbour office. Older steel and bulk carriers on tramp trades are the type most likely to be selected, and structural condition in cargo holds and ballast tanks is something an inspector may look at if the ship has a record of previous findings. Fresh thickness data taken before arrival gives the master and the superintendent a clear picture if a question about hull condition comes up.
Several EU rules shape why owners gauge ships that trade through Italian ports. The Ship Recycling Regulation requires an Inventory of Hazardous Materials for ships calling at EU ports, which makes sense for owners to settle at the same time as a major structural survey. EU ETS and FuelEU Maritime now apply to larger ships, and owners of older tonnage weigh steel renewal against replacement using measured data. The Piombino steel trade also means carriers here are often smaller handysize and coastal bulkers, where each docking is a significant decision and accurate wastage figures carry weight.
Since 1 May 2025 the whole Mediterranean has been a sulphur emission control area, so ships calling at Piombino 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.
Typical thickness gauging jobs in Piombino
The jobs we expect at Piombino fall into three groups: hold and tank-top programmes on steel and bulk carriers, ferry readings built up over successive turnarounds, and condition checks on ships changing hands or finishing a charter. Most are done alongside, so scope is agreed with the master in advance, and we keep a clear list of spaces so that the readings are ready to hand to the surveyor or the yard without rework.
- Hold-by-hold gauging of tank tops, hopper tanks and lower hold side plating on a steel carrier after discharge, ahead of a renewal survey
- Hatch cover panel and coaming readings on a general cargo ship that carries coils and plate, where crane and grab damage is expected
- Ferry vehicle deck, ramp and ballast tank readings taken over several turnarounds on the Elba crossing, building a pre-docking picture
- Owner's condition gauging of a bulk carrier at anchor in Piombino roads while it waits for a berth, to decide where to dock
- Off-hire thickness record on a chartered coaster before redelivery, supplying both owner and charterer with the same readings
How a thickness measurement job runs at Piombino
The sequence for a thickness measurement job at Piombino is short and written down, so the yard, the surveyor and the superintendent know who arranges what.
The nearest large airports are Pisa and Florence for most European connections, and Rome Fiumicino for long-haul, with onward travel to Piombino by road or rail and road. Port entry is arranged by the ship's agent, who issues the ISPS passes and books a launch for ships at anchor. Because the inspectors come from India, a Schengen visa application is made once the ship's call is confirmed, so the owner should treat visa processing as part of the planning for any job in Italy.
- 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.
Who does the work, and when class approval applies
We send the team from India to the ship for each job rather than keeping staff at the port, and plan the mobilisation around visas and the vessel's itinerary. The work is planned and supervised by the founder, our Responsible NDT Level III (ASNT NDT Level III in UT, RT, MT, PT and VT, with more than eleven years of international field experience). Technicians hold certification under the company's written practice to ASNT SNT-TC-1A; Atlantis is ISO 9001 and ISO 14001 certified.
Thickness measurement that a classification society credits to a class survey has to be carried out by a firm approved by that society under IACS UR Z17. Atlantis is in the process of obtaining UR Z17 approval from DNV, Lloyd's Register and ABS. Until a certificate is issued, the readings we take are for the owner's own decisions, not for credit to a class survey, so tell us the vessel's class and the survey due when you enquire and we set the scope for the right purpose. Owner's and charterer's condition gauging, pre-docking steel estimates, pre-purchase and on-hire or off-hire gauging, and scrubber and piping condition checks between surveys do not need class approval.

Frequently asked questions
Can cargo holds be gauged at Piombino during discharge?
Only once the hold is empty, swept and made safe for entry. Gauging while cranes or grabs are still working inside the hold is not safe, so we plan the work for the gap between finishing discharge and the next loading, and agree with the master which holds will be ready first.
Is there a drydock at Piombino for a full docking survey?
Piombino is mainly a cargo and ferry port, so owners usually take ships to a repair yard elsewhere on the Tyrrhenian for docking. We can gauge at Piombino beforehand to size the steel work, and then follow the ship to the yard, using the same measurement points so the readings can be compared.
Can you gauge a ferry on the Elba service without disturbing the timetable?
Usually yes, in blocks. A ramp, a section of vehicle deck or a group of tanks can be done during a turnaround, and further blocks follow on later calls. We agree the order with the superintendent so every visit has a target and the readings join up into one report.
Does thickness gauging on a ship at anchor near Piombino work?
It can, with a launch, calm enough weather and tanks that the crew has ventilated and certified gas-free. It suits owner's condition checks and pre-purchase work. Surveys tied to a class record usually need the ship alongside or in dock, so we confirm the purpose before planning the anchorage visit.
Do you also measure ships serving the LNG terminal at Piombino?
We can take readings on accessible hull and deck areas of visiting ships if the owner asks and the terminal's rules allow it. Work around gas carriers is tightly controlled, so the scope is narrow and agreed in advance with the master, the agent and the terminal operator.
Does thickness measurement at Piombino need class approval?
Thickness measurement that a classification society credits to a class survey has to be carried out by a firm approved by that society under IACS UR Z17. Atlantis is in the process of obtaining UR Z17 approval from DNV, Lloyd's Register and ABS. Until a certificate is issued, the readings we take are for the owner's own decisions, not for credit to a class survey, so tell us the vessel's class and the survey due when you enquire and we set the scope for the right purpose. Owner's and charterer's condition gauging, pre-docking steel estimates, pre-purchase and on-hire or off-hire gauging, and scrubber and piping condition checks between surveys do not need class approval.
