Thickness Gauging at Brunsbüttel for Tankers, Bulk Carriers and Kiel Canal Ships

Inspection services for ships at Brunsbüttel

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

Where ships can be gauged at Brunsbüttel

Brunsbüttel has no merchant ship dry dock, so gauging is carried out afloat during cargo operations or on lay-by. At the Elbehafen, bulk carriers give a hold window after discharge, multipurpose ships give tween-deck and hatch access between lifts, and tankers can have ballast tanks, decks and engine-room piping measured while cargo is handled under the terminal's rules. At the oil and Ostermoor harbours on the canal, chemical and product tankers follow the same pattern, with cargo tanks entered only once they are gas-freed.

LNG carriers discharging to the regasification unit operate under strict gas-safety arrangements, so any work aboard them is confined to spaces well away from the cargo system and has to be agreed with both the ship and the terminal operator. For dockings, ships go to the Hamburg yards up the Elbe, to Bremerhaven, or to Baltic yards reached through the canal, and thickness data taken at Brunsbüttel can serve as the yard's steel estimate. Ships that need a longer stop can be laid by at a berth arranged through the agent and the port.

• Elbehafen bulk berths — hold, hopper and tank-top gauging on bulk carriers after discharge.
• Elbehafen multi-purpose quay — tween-deck, hatch cover and crane pedestal checks on project and general cargo ships.
• Elbehafen liquid berths — ballast tank, deck and engine-room readings on tankers within terminal rules.
• Oil harbour on the canal — chemical and product tanker gauging of ballast tanks and deck piping.
• Ostermoor harbour on the canal — work on tankers and bulk ships serving the industrial park.
• Yards in Hamburg, Bremerhaven and the Baltic — the usual docking destinations, using Brunsbüttel readings for steel planning.

Port state control, ice class and energy trades at Brunsbüttel

Port state control at Brunsbüttel is a Paris MoU matter, carried out by BG Verkehr's Ship Safety Division, and the Kiel Canal adds its own traffic rules, administered by the federal waterways authority, for ships in transit. Many ships passing through are bound for Baltic ports where winter ice is normal, and those trading into the northern Baltic carry ice class under the Finnish-Swedish rules. Ice-belt plating at the bow and waterline wears faster than the rest of the shell, and owners preparing a ship for a winter of Baltic trading often want the ice belt, the bow and the frames behind it measured before the season starts.

Energy is the other theme. The regasification unit at the Elbehafen is part of Germany's LNG import system, operated by the state-owned Deutsche Energy Terminal, and an onshore LNG terminal is planned for the site, so LNG carriers have become regular callers. Chemical and fertiliser plants in the ChemCoast Park bring chemical tankers, gas carriers and bulk carriers. For all of them, EU ETS (from 2024) and FuelEU Maritime (from 2025) now reach voyages into the EU, and the EU Ship Recycling Regulation requires each of these ships to keep an Inventory of Hazardous Materials on board while calling here.

Ships trading to Brunsbüttel 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 Brunsbüttel

Most of the work on a Brunsbüttel job happens before the team boards: scope, plan and access are settled first, so the time on board goes on measurement.

Hamburg Airport is the nearest international airport, and the team reaches Brunsbüttel by road along the north side of the Elbe; the Glückstadt to Wischhafen car ferry links the area with the Lower Saxony shore when a trip combines Brunsbüttel with Stade or Cuxhaven. Terminal access at the Elbehafen and the canal harbours is ISPS-controlled and arranged by the ship's agent, with extra safety induction at the chemical and LNG berths. The technicians from India travel on Schengen visas, so expected call dates should reach us early.

• 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.
