UTM at Cartagena and Escombreras: Hull Gauging for Tankers and Gas Carriers

Inspection services for ships at Cartagena

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

Where gauging takes place in Cartagena and Escombreras

Most tanker work happens at the Escombreras berths, where the ship is bound by terminal permit-to-work rules and the cargo programme. Spaces that are inert or gas-free can be gauged once the ship's enclosed-space entry system is in place, and we tailor the scope to what the chief officer can prepare during discharge. Bulk and general cargo ships in the main harbour offer more relaxed access, with holds, decks and ballast tanks readable once the cargo operation has paused.

The naval yard in the city is a specialist facility geared to its own customers, and merchant ships needing drydocking normally go to yards elsewhere in the western Mediterranean. Cartagena has repair firms for afloat work, including piping, tank cleaning and steel renewal in some cases, and these can be coordinated with gauging so the findings feed straight into the repair list. When a deep docking is needed, the choice is usually between yards in Spain, Gibraltar and across the Strait, and thickness readings taken in Cartagena make the comparison more precise. Anchorage work is possible for short jobs, subject to sea state and launch availability.

• Escombreras tanker and gas berths — hull, deck, ballast tank and piping readings under terminal permit-to-work rules during discharge
• Bulk and general cargo quays in the main harbour — hold frame, hatch coaming and deck gauging after discharge
• Cruise and passenger berths — voids, sea-water lines and scrubber piping on turnaround days
• Port repair firms for afloat work — gauging combined with piping and plating repairs so steel renewal is planned in one stop
• Cartagena anchorage — short sampling jobs on tankers and bulkers waiting for orders, subject to weather and launch access
• Docking yards elsewhere in the western Mediterranean — gauging started here continues alongside the docking survey

Port state control, ESP rules and the energy trades

Port state control at Cartagena is under the Paris MoU, carried out by the Capitanía Marítima of Cartagena under the Dirección General de la Marina Mercante. Tankers and gas carriers are subject to extra scrutiny because of their cargo, and inspectors are quick to examine structural condition and corrosion of ballast tanks and deck piping. For ships under the Enhanced Survey Programme, thickness records are central to how class and the owner track substantial corrosion between surveys.

The energy character of the port brings its own pressures. Tanker owners need to keep ships in demand with refiners and charterers, many of whom ask for a recent thickness picture or a condition assessment before taking a ship on. EU rules add detail: the Ship Recycling Regulation requires an Inventory of Hazardous Materials, EU ETS and FuelEU Maritime affect voyages calling here, and shore-side projects around Escombreras keep energy flows changing. Older product tankers and gas carriers trading in this area benefit from having a readings history, and pitting or grooving in ballast tanks is easier to manage when it is measured early.

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

A gauging job at Cartagena 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.

The team normally flies to Murcia-Corvera or Alicante-Elche airport, the latter having wider European and Gulf connections, and continues by road to Cartagena. Valencia is another option with a long road transfer. Port and terminal passes for Escombreras are arranged by the ship's agent, who also books a launch for anchorage work. Schengen visas are required, so please provide expected dates early; we confirm mobilisation once visas are issued, because tanker calls can move with cargo programmes.

• 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.
