Ship Thickness Measurement in Constanța and the Romanian Black Sea Ports

Inspection services for ships at Constanța

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

Where gauging happens in Constanța and along the Romanian coast

Constanța Shipyard, inside the port, is the main place for in-dock gauging on the Romanian coast. A docking there gives access to bottom shell, bilge plating and sea chests, and the staging the yard rigs for hold and tank repairs gives reach to upper frames and deckheads that are otherwise hard to measure. The most useful gauging is done early in the docking, so that the yard, the owner and the class surveyor work from one set of figures when they agree what is cropped and renewed on the steel list.

Most other work is afloat. The terminals across the port offer alongside access for bulk carriers, tankers and container ships between cargo operations, with gate passes arranged through the agent, while the outer anchorage holds ships waiting for berths. Midia, a short distance north, adds refinery tanker berths, and Mangalia, to the south, is a further port on the same coast. River-sea ships calling at Constanța can be gauged alongside at whichever berth they work, with the measurement grid adjusted to their lighter scantlings and to the class notation they trade under.

• Constanța Shipyard — shipbuilding and repair yard within the port; a docking here opens up bottom, bilge and sea chest areas for a full renewal-survey gauging programme.
• Constanța South and Agigea — container terminals and the Danube–Black Sea Canal entrance; deck and tank gauging on container ships and river-sea traffic alongside.
• Bulk berths across the port — grain, ore, coal and general cargo; the turnaround between cargoes leaves holds open for frame, hopper and tank-top readings.
• Midia port, Năvodari — refinery tanker berths serving Petromidia; deck, ballast tank and deck-pipeline gauging during cargo operations, under terminal rules.
• Constanța anchorage — ships queuing for grain and other berths; boarding by launch for ballast tank, hatch cover and deck measurements.

Romanian port state control, EU rules and Black Sea conditions

Romania carries out port state control through the Romanian Naval Authority and, as an EU member, takes part in the Paris MoU as well as the Black Sea MoU. Ship age and type feed into the risk profile that sets how often a ship is inspected, so an ageing bulk carrier or tanker calling regularly at Constanța should expect expanded inspections. For ESP ships, preparation means more than the hull itself: the survey report file, the latest thickness measurement reports and the condition evaluation report must be on board and current, because an inspector who finds them missing or out of date has a reason to look harder at the structure.

Romanian waters of the Black Sea carry no ECA designation, but EU rules take over alongside: a 0.10% sulphur ceiling for ships at berth unless an abatement method is used, the EU ETS on voyages to and from Constanța since 2024, and FuelEU Maritime from 2025. Romania's full accession to Schengen in January 2025 means a team travelling from India needs a Schengen visa. Since 2022, drifting mines have been reported in the western Black Sea, and Romania, Bulgaria and Turkey set up a joint mine-countermeasures group in 2024. Routing and war-risk cover follow the owner's and underwriters' advice, and in-port gauging is scheduled within that guidance.

Wherever a ship is outside a sulphur emission control area, the global 0.50% sulphur cap applies, and many of the ships calling at Constanța meet it with an exhaust gas cleaning system rather than compliant fuel. Scrubber wash-water piping, the overboard discharge and the hull penetration around it corrode quickly in service, especially on open-loop systems, and are worth adding to the gauging scope.

How a thickness measurement job runs at Constanța

A gauging job at Constanța 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.

International connections run through Bucharest Henri Coandă Airport, with road or rail transfer to the coast, and Mihail Kogălniceanu Airport near Constanța has a smaller schedule of flights. The shipyard and the port terminals are ISPS-controlled, so the ship's agent applies for access permits covering each technician and the gauges, using passport details sent ahead, and books launches for anchorage boardings. Because Romania is in the Schengen area, the India-based team needs Schengen visas; we start the application once the docking or ETA window is firm and keep the owner informed of the visa timeline.

• 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.
