Málaga Ship Gauging: Hull and Tank Thickness Surveys on the Costa del Sol

Inspection services for ships at Málaga

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

Where gauging happens in Málaga

Nearly all of the thickness work in Málaga is done alongside. Passenger ships offer the most structured access, because the technical department can have tanks opened, ventilated and tested before arrival, and the ship's own entry procedure covers the team. Ferries on the Melilla route are accessible between rotations, with car decks and ramps easy to reach once the vehicles have gone. Cargo ships at the commercial quays allow hold, hatch coaming and deck work during or after discharge, if the terminal accepts it.

There is no large drydock in the harbour for deep-sea tonnage, so ships needing steel renewal usually dock in the Bay of Cádiz, at Gibraltar or in a larger Mediterranean yard. The port has facilities for smaller craft such as tugs, workboats and fishing boats, and these can be hauled out or worked afloat by local repair firms. For anything larger, the useful job in Málaga is to establish the wastage picture, so the docking yard is chosen and briefed on measured data. Ships waiting in the bay can be gauged at anchor only for short jobs, subject to launch access and weather.

• Cruise terminals on the passenger quays — voids, ballast and service tanks, sea-water cooling lines and scrubber piping on turnaround days
• Ferry berths for Melilla services — car decks, ramps, hoistable decks and ballast tanks between rotations
• Commercial quays — hold, hatch coaming, deck and tank readings on bulk and general cargo ships during or after discharge
• Repair quay used by tugs and workboats — hull plating readings on harbour craft before a haul-out elsewhere
• Málaga Bay anchorage — a short sampling job for a ship waiting for orders, subject to weather and launch access

Regulation, port state control and trade around Málaga

Ships calling at Málaga are subject to port state control under the Paris MoU, carried out in Spain by the Capitanías Marítimas under the Dirección General de la Marina Mercante. Inspectors are particularly interested in structural condition and in the fire main, bilge and ballast piping when ships have carried out long periods without a docking. Measured readings from a recent gauging help a master explain wastage to an inspector and show that steel has been assessed rather than ignored. Passenger ships and ro-pax ferries also face attention to the integrity of watertight bulkheads and doors.

EU rules add pressure for owners with a long-term plan. The Ship Recycling Regulation requires ships calling at EU ports to carry an up-to-date Inventory of Hazardous Materials, EU ETS covers emissions from ships on EU voyages, and FuelEU Maritime now applies to energy use. Cruise lines and ferry operators in this corner of Spain are investing in shore power and cleaner fuel, and any retrofit that opens up structure is a good moment to take a baseline set of thickness readings. Where tonnage is old, the data also informs decisions on whether to renew steel, sell or lay up.

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

A gauging job at Málaga runs the same way whatever the ship type. The sequence below is what the superintendent, the attending surveyor and the yard can expect from us.

Málaga-Costa del Sol Airport has regular connections with European and Gulf hubs, which suits technicians travelling from India, and the port is a short road trip from the terminal. The ship's agent arranges port passes, gangway access and a launch if the ship is at anchor. Schengen visas are needed for the team, so please send the vessel's dates early; for a planned ferry or cruise programme that is easy, and for a short-notice call we confirm what is possible once visas are issued.

• 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.
