Hull Thickness Gauging for Container Ships and Car Carriers in Bremerhaven

Inspection services for ships at Bremerhaven

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

Where Bremerhaven gauging is carried out

Bredo Dry Docks, in the Fischereihafen area, operates floating docks that take container ships, ro-ro ships, offshore vessels and other commercial ships, and further repair yards and quays in the port handle afloat work. In dock, hull gauging in Bremerhaven follows the TM plan and the class surveyor's close-up programme. The car terminal, ro-ro berths and breakbulk quays inside the locks are the main afloat workplaces, with time set by the cargo operation and safe access to the decks provided by the ship.

On the river, the container terminals allow work aboard within the ship's own permit system while cargo continues, which suits scrubber piping, deck structure and hatch coamings. The cruise terminal sees passenger ships whose turnaround days are packed, so gauging there is limited to tightly defined scopes such as specific tanks or piping runs. Offshore wind installation and support vessels laid up in the basins between projects are among the easiest ships to gauge thoroughly, because they are idle and their crews can open tanks and voids without cargo pressure. Ships at the outer anchorages are reached by launch, for small jobs only.

• Bredo Dry Docks, Fischereihafen — in-dock renewal and intermediate survey gauging on container ships, ro-ro ships and offshore vessels, with renewal plates marked for the yard.
• Car terminal inside the Kaiserschleuse and Nordschleuse — car carrier gauging of fixed and hoistable decks, ramps and door structure between discharge and loading.
• Container terminals on the Weser river quay — scrubber discharge lines, hatch coamings and deck plating measured during a liner call.
• Ro-ro and breakbulk berths in the overseas port basins — main-deck, tank-top and hold gauging on ro-ro and project-cargo ships during staged loading.
• Lay-by berths in the overseas port — longer jobs on offshore and research vessels between campaigns, including tanks, voids and crane pedestals.
• Columbus Cruise Center — narrowly scoped tank and piping gauging on cruise ships during their turnaround.

What drives inspection demand around Bremerhaven

Bremerhaven is a German port under Paris MoU port state control, and the Weser estuary falls within the North Sea SOx ECA, which holds fuel sulphur to 0.10%. Container ships arriving from long-haul routes switch fuel or run scrubbers before they enter the ECA, and the wash-water and overboard lines on those scrubbers are a known wastage area that rewards regular gauging. Local restrictions on open-loop discharge in port waters should be confirmed with the agent before each call.

The car terminal handles German-built vehicles for export as well as imports, together with high-and-heavy cargo such as construction and agricultural machinery, so the vehicle carriers here range from pure car carriers to heavy-deck ro-ro designs. Owners are renewing these fleets with new dual-fuel ships, and the older vessels that keep trading on European routes now carry carbon obligations under EU ETS (for shipping from 2024) and FuelEU Maritime (from 2025). Whether an older PCTC is worth another five-year cycle depends partly on how much deck and ramp steel it will need, and gauging during a Bremerhaven call can answer that question with measurements.

Ships trading to Bremerhaven 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 Bremerhaven

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

Bremen Airport is the closest airport with European connections, and Hamburg Airport offers wider international routes; both are linked to Bremerhaven by road and rail. The container terminals, the car terminal and the yards are ISPS-controlled, and the agent registers the team and confirms which lock or quay the ship will use. As Germany is in the Schengen area, the team from India travels on Schengen visas, so docking and call dates should be sent as early as possible; we then fix mobilisation to the confirmed berth plan.

• 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.
