Ship Hull and Deck Gauging in Brindisi, Gateway to Greece

Brindisi is an old Adriatic harbour with a modern working life: ferries to Greece and Albania, tankers serving the industrial and energy zone, and bulk and general cargo ships at the outer quays. Ferry owners want car decks and ramps measured between sailings, and energy-trade ships need deck and tank readings before surveys. Atlantis NDT sends its thickness measurement technicians from India to the ship and plans each job around the sailing timetable and the cargo window.

Greece and Albania ferry rotations

Ro-pax ships on the Greek and Albanian crossings return on fixed timetables, so car deck, ramp and ballast tank gauging can be divided across several turnarounds without disturbing a single sailing.

Energy and industrial zone tankers

Brindisi's petrochemical and energy facilities bring product and chemical tankers and coal and bulk ships, where deck piping, ballast tank and hold readings are tied to survey schedules and charterer checks.

Sheltered harbour with room to work

The outer harbour, protected by breakwaters and an offshore island, gives ships calm berths and anchorage, which makes it easier to plan tanks, decks and piping readings within a fixed working window.

The port of Brindisi: outer harbour, ferry quays and the industrial zone

Brindisi sits on the Adriatic coast of Puglia, near the heel of Italy, and has served the sea route to Greece for more than two thousand years. The modern port is built around a natural harbour with three parts: an outer harbour sheltered by breakwaters and a small island at its mouth, a middle harbour, and an inner basin that reaches towards the old town. Ferry and cruise berths are on the Costa Morena side, while industrial and bulk quays lie along the outer harbour and the eastern shore. Ships approach from open water in the Adriatic through a dredged entrance channel, and the tidal range is small.

The traffic mix splits into passenger shipping and industrial cargo. Ro-pax ferries link Brindisi with Greek ports such as Igoumenitsa and Patras and with Albania, and cruise ships call in season. On the industrial side, the energy and petrochemical zone to the south and east of the city generates tanker calls with refined and chemical products, and coal and other dry bulk have long arrived for the power and industrial users nearby. General cargo and project cargo, including components for energy projects, use the multipurpose quays of the outer harbour.

Gauging demand follows from that split. Ferries accumulate wear on vehicle decks, stern and bow ramps and the ballast tanks below, because trailers, road salt and condensation work on the same steel every day of a season. Tankers and bulk carriers behave as they do in any energy port: deck piping, ballast tanks, cofferdams and hold frames drive the survey calendar. Strong northerly winds in winter can delay berthing for a while, and the summer peak on the Greek services leaves ferries with very little spare time alongside, which is why jobs for them are planned in short blocks.

Where gauging happens in Brindisi: ferry berths, tanker jetties and outer quays

Ferry gauging takes place at the passenger berths on the Costa Morena side, during turnaround. A ro-pax ship usually has a few hours between disembarkation and the next boarding, and a well-prepared job fits inside that: the vehicle deck is cleared, the ramp is lowered, and readings are taken along marked lines on plating, stiffeners and ramp hinges. Off season, ferries lay by for longer, and the same ship can have its ballast tanks and void spaces measured at leisure. Class surveyors attend when readings are meant for the survey file.

Industrial berths work differently. Tanker jetties in the energy and petrochemical zone apply their own permit rules, so deck and piping gauging goes ahead during cargo operations under the terminal's safety conditions, and entry to cargo tanks is left for a yard. The port has no large commercial drydock of its own, so owners dock ships at yards elsewhere in Italy, Greece, Malta or Croatia, and a measured steel estimate prepared at Brindisi helps the chosen yard to plan renewal. Ships waiting for a berth lie at anchor in the outer roads, where owner's condition checks of accessible spaces are possible in calm weather.

  • Costa Morena ferry berths — vehicle deck plating, stiffeners, ramps and ballast tanks of ro-pax ships gauged during turnaround between sailings
  • Cruise berths — selected ballast tanks, voids and scrubber lines on cruise ships alongside, between passenger operations
  • Tanker jetties in the energy and petrochemical zone — deck, deck piping and permitted ballast spaces on product and chemical tankers
  • Outer harbour bulk and general cargo quays — hold frames, hatch covers and coamings after discharge on coal and dry bulk ships
  • Outer anchorage — condition checks on ships waiting for a berth or laid up, reached by launch through the ship's agent

Thickness measurement through the survey cycle at Brindisi

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 Brindisi is agreed in writing before mobilisation.

SurveyWhen it fallsWhat the thickness measurement usually covers
Annual surveyEvery year, within three months of the anniversary dateGeneral examination. Gauging where the surveyor finds suspect areas or where substantial corrosion was recorded at an earlier survey.
Intermediate surveyIn place of the second or third annual surveySuspect 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. 1Around 5 yearsThe first full baseline: suspect areas and selected plating and stiffeners, usually with modest steel renewal.
Renewal survey No. 2Around 10 yearsWider gauging of deck, bottom and side plating, transverse sections across the cargo area on ESP ships, and more close-up survey.
Renewal survey No. 3Around 15 yearsExtensive 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 laterAround 20 and 25 yearsGauging extended to most structural members in cargo and ballast spaces. Charterers often add a Condition Assessment Programme.
Docking surveyTwice in each five-year periodBottom and side shell, sea chests, rudder and stern area while the hull is dry; suspect bottom plating gauged.

Port state control and regulation for ferry and energy shipping at Brindisi

Port state control at Brindisi is carried out by the Italian Coast Guard through the harbour master (Capitaneria di Porto), within the Paris MoU. Ro-pax ferries are additionally subject to the EU's regime of mandatory surveys for regular passenger services, which makes a continuous record of deck and ramp condition useful to owners who must show surveyors that wear is under control. Bulk carriers and tankers face ESP requirements, and the ship risk profile decides how often an older vessel is boarded. Structural deficiencies are one of the categories that can lead to detention.

Brindisi's role as a gateway to Greece and Albania has commercial consequences. Ferry operators run old tonnage hard through peak summers, and owners looking at a sale, a charter extension or a refit need credible wall-thickness figures. The EU Ship Recycling Regulation asks ships calling at EU ports to carry an Inventory of Hazardous Materials, and EU ETS and FuelEU Maritime shape the economics of keeping older ships in service. For energy-trade tankers the charterer's vetting inspector also reads the structural record, and a recent set of gauging results saves long discussions.

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

Brindisi work divides between the ferry timetable and the cargo calendar. Ferry jobs are short, repeatable and planned deck by deck, while tanker and bulk jobs are longer and depend on the terminal's permit conditions. We agree the sequence of spaces, entry permits, surface preparation and report format with the superintendent beforehand, and leave remaining spaces for a later call or a yard stay.

  • Vehicle deck and stern ramp gauging on a Greek-service ro-pax ship, divided over several turnarounds ahead of a renewal survey
  • Ballast tank and void space readings on a ferry during winter lay-by, to compile steel estimates before a docking
  • Deck piping and main deck gauging on a product tanker at a jetty in the energy zone, with the ballast tanks declared safe for entry
  • Hold frame and hatch coaming gauging on a coal carrier after discharge at the outer harbour quays, closing out items from the last annual survey
  • Owner's condition survey of a general cargo ship at anchor before an on-hire or purchase decision

How a thickness measurement job runs at Brindisi

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

Brindisi Airport, Salento, is close to the port, and Bari airport is a longer road alternative with more connections. The ship's agent books ISPS passes and any terminal induction for the tanker jetties and passenger berths. Our technicians are Indian nationals who travel on Schengen visas, so we start the application as the call is confirmed, and fix flights once the ferry's turnaround slot or the tanker's berth time is certain. Because ferries sail on fixed times, a late arrival of the team shortens the work window, which is why we travel a day ahead.

  • 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

The inspection team is mobilised from India for each job; nobody is stationed at the port, so mobilisation is planned against the vessel's schedule and visa lead times. Our founder and Responsible NDT Level III, who holds ASNT NDT Level III in UT, RT, MT, PT and VT and has over eleven years of international field experience, plans and supervises the work. Technicians are certified under the company's written practice to ASNT SNT-TC-1A, and the company holds ISO 9001 and ISO 14001 certification.

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 a ferry vehicle deck be gauged between sailings in Brindisi?

Yes, if the job is planned tightly. We fix the zones of the deck in advance, mark lines on the plating, and measure only what the turnaround allows. The next block is picked up on a later call. All readings are combined in a single report, so the surveyor sees a complete record rather than separate partial sets.

Does Brindisi have a drydock for a renewal survey?

Not for large merchant ships. Owners usually book a yard in Italy, Greece, Malta or Croatia. We can gauge the ship at Brindisi beforehand, giving the yard measured steel estimates, then travel to the yard for the full programme so that readings remain comparable from the first estimate to the final report.

Can you measure ramp hinges and ramp plating on a ro-pax ship?

Yes. Ramp plating, stiffeners and the structure around hinges and securing points are measured with the ramp lowered and the area clear of traffic. Surface condition and coating need to be recorded with each reading, and we agree with the ship's crew who prepares the area before the team arrives.

Is gauging possible at the tanker jetties in Brindisi?

For deck, piping and permitted ballast spaces, yes, within the terminal's permit rules. Entry into cargo tanks is not allowed during cargo operations, so cargo tank gauging is planned for a yard stay. The agent arranges terminal access and induction in advance, and we keep the equipment list ready for inspection at the gate.

What happens if winter weather delays a ship at Brindisi?

The job moves with the ship. Strong northerly winds can delay berthing, and we keep the plan flexible, fixing flights only once the berth time is firm. A delayed ferry or tanker often has less time on arrival, so we prioritise the most critical spaces first and leave lower-priority readings for the next call.

Does thickness measurement at Brindisi 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.
