UTM for Ro-Pax Ferries, Ro-Ro Ships and Feeders in Lübeck and Travemünde

Inspection services for ships at Lübeck

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

Where ships are gauged in Lübeck and Travemünde

The Skandinavienkai is where most ferry gauging happens. A ro-pax ship there is alongside a linkspan with cargo moving across its decks, so the team works in spaces away from the traffic, such as engine-room piping, sea water inlet lines, voids and tanks the crew can empty, and steps onto the vehicle decks only when the lanes have cleared. Lübeck has no commercial drydock for ships of this size, and the ferries and ro-ro ships calling here dock at yards in Poland, Denmark, Finland or elsewhere. Gauging at Travemünde before such a docking lets the superintendent arrive at the yard with a steel estimate already prepared.

The river terminals give longer, quieter windows. Ro-ro ships discharging forest products at the Nordlandkai and neighbouring quays can release ballast tanks and voids for gauging while cargo work continues on deck, and ships waiting for a berth or for their next sailing lie at lay-by quays on the Trave. Container feeders at the city terminal are measured during short calls for specific items. Ships at anchor in Lübeck Bay are reached by launch for small scopes when the weather allows boarding.

• Skandinavienkai, Travemünde — engine-room piping, voids, tanks and vehicle-deck plating on ro-pax ferries to Finland, Sweden and Latvia.
• Nordlandkai and other river quays — ballast tank, void and lower-hold gauging on forest-product ro-ro and con-ro ships during discharge.
• Container terminal in the city port — scrubber wash-water lines, deck plating and hatch covers on Baltic feeders during short calls.
• Lay-by quays along the Trave — longer programmes on ferries out of service, ships awaiting charter and vessels for sale.
• Lübeck Bay anchorage — small, pre-planned scopes by launch when the ship is waiting to enter the river.

Ro-pax rules, winter navigation and port state control

Ro-pax ferries in regular service from Lübeck are inspected under Directive (EU) 2017/2110, which requires pre-commencement and regular inspections of ro-ro passenger ships by the host state, on top of class surveys and Paris MoU port state control. German inspections are carried out by the Ship Safety Division of BG Verkehr. Fire mains, sea water systems, bilge piping and the structure around bow and stern doors are among the items those inspections follow closely. An operator with recent wall-thickness readings on those systems is in a stronger position when inspectors or the flag state ask how the ship's piping has aged.

The Finnish routes add winter navigation. Finnish and Swedish authorities set ice-class and minimum-size restrictions for ports in the northern Baltic each winter, and the Finnish-Swedish ice class rules determine how a ship's ice belt is built. Shell plating and framing there wear faster than elsewhere on the hull, from abrasion and repeated contact with ice. Ferry operators on these routes also carry the weight of EU emissions rules on frequent, fuel-intensive crossings, with the ETS since 2024 and FuelEU Maritime since 2025, while the EU Ship Recycling Regulation obliges every ship calling at an EU port, whatever its flag, to keep an Inventory of Hazardous Materials on board.

Ships trading to Lübeck are inside a sulphur emission control area, where fuel must not exceed 0.10% sulphur unless an exhaust gas cleaning system (scrubber) is fitted. Scrubber wash-water piping, the overboard discharge and the hull penetration around it are among the fastest-corroding parts of a modern ship, so they belong in the gauging scope at every docking and, on open-loop systems, between dockings.

How a thickness measurement job runs at Lübeck

The sequence for a thickness measurement job at Lübeck is short and written down, so the yard, the surveyor and the superintendent know who arranges what.

Hamburg Airport is the usual international arrival point, with road and rail connections to Lübeck and a local rail line on to Travemünde. The ferry and ro-ro terminals are ISPS-controlled, and on passenger ships the team's boarding is aligned with the ship's security plan; the agent registers names and equipment in advance. The technicians travel from India on Schengen visas, and because the ferry timetables are published well ahead, a mobilisation date can usually be fixed early and kept.

• 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.
