Ship Thickness Measurement at Port Said and the Northern Suez Canal
Port Said sits at the Mediterranean entrance to the Suez Canal, where southbound convoys assemble and container ships tranship at East Port Said. Few ships stop for long, which makes most work here targeted: a follow-up on suspect areas, a check on scrubber piping, or repair-boundary work at Port Said Shipyard. Technicians fly in from India to fit the ship's schedule, working through the agent at the anchorage, the terminals or the yard.
Targeted gauging around the transit
Southbound ships usually wait only a short time at anchor for their convoy. Port Said anchorage gauging therefore suits targeted measurements, such as re-gauging areas flagged at the last survey or checking a suspect deck or pipe, rather than a full programme.
Transhipment calls at East Port Said
Container ships calling at the East Port Said terminal, on the Sinai side of the canal entrance, spend their time alongside working cargo. Scrubber wash-water and overboard piping, hatch coamings and accessible tanks can be gauged during the call.
Repairs at Port Said Shipyard
Port Said Shipyard, owned by the Suez Canal Authority, takes ships for repair at the northern end of the canal. When a defect found in transit leads to a yard stay, gauging defines the repair boundary and supports the class surveyor's decision.

ExplorePort Said and the northern entrance to the Suez Canal
Port Said and Port Fouad face each other across the northern end of the Suez Canal, with the city's west-bank harbour on one side and East Port Said, with its container terminal and industrial zone, on the other. Almost every ship using the canal passes through here, from container ships and tankers to bulk carriers, car carriers and LNG carriers. Southbound ships arrive at the anchorage off Port Said in the Mediterranean, are allocated a convoy and pilot, and enter the canal on schedule; northbound ships leave the canal here. East Port Said is also a transhipment hub inside the Suez Canal Economic Zone, so part of the traffic stops to work cargo rather than simply passing through.
The defining feature for gauging is time. A transit ship's stay at the anchorage is usually short, and the master's priorities are the canal formalities, the pilot and the convoy. That rules out a full renewal-survey programme on most transit calls, but it leaves room for focused work: measuring an area of suspect corrosion so it can be reported to class, checking a deck pipe or vent that a class surveyor or a port state control inspector has queried, or taking readings on scrubber overboard lines between drydocks. Ships that stop for bunkers, stores, crew changes or repairs, or that wait at anchor for orders, offer longer windows and wider scopes.
Inspection demand at Port Said is shaped by the canal's role as a junction. Ships heading into the Mediterranean emission control area must be on compliant fuel or running their scrubbers by the time they leave the canal, and scrubber wash-water piping on hard-worked container ships is a recurring inspection concern. Since late 2023, attacks on merchant ships in the southern Red Sea have led many operators to route around the Cape of Good Hope, cutting the number of canal transits. Traffic through Port Said has followed those routing decisions, and attendance here is planned around each owner's current routing.
Gauging locations at Port Said
There are four practical places to work. The anchorage off Port Said is where transit ships and ships waiting for orders lie; the agent books the launch, and boarding is timed so the gauging finishes well before the convoy call. East Port Said's container terminal offers alongside access to ships working transhipment cargo, subject to the terminal's ISPS controls and the stevedores' working zones. The berths of the west-bank harbour handle general cargo, bulk and service vessels, and Port Said Shipyard handles repair work, including drydocking.
Because time is short, preparation matters more for hull gauging at Port Said than at most ports. We ask for the last thickness measurement report, any class findings or port state control deficiencies, drawings of the area of concern and the expected time at anchor before the team travels, and the measurement points are laid out in advance so the team can board, measure and leave within the window. Where the readings point to a repair, the same data supports the decision on whether to repair at Port Said Shipyard, defer to the next planned yard, or agree a temporary measure with class.
- Port Said anchorage — southbound transit ships and ships waiting for orders; targeted deck, tank and piping gauging timed around the convoy schedule.
- East Port Said container terminal — transhipment calls inside the Suez Canal Economic Zone; scrubber piping, hatch coaming and accessible tank gauging alongside.
- Port Said Shipyard — Suez Canal Authority repair yard; drydock and repair-berth stays allow repair-boundary gauging and wider renewal-survey work.
- West-bank harbour berths — general cargo, bulk and service vessel berths in the city; deck, hold and tank gauging during cargo work or lay-by.
- Damietta, west along the coast — a separate Egyptian Mediterranean port where the same mobilisation can attend bulk carriers and container ships.
Thickness measurement through the survey cycle at Port Said
Class rules set the survey cycle, and the cycle sets how much gauging a ship needs. A superintendent planning a call at Port Said usually knows which survey is due; the table shows what the thickness measurement for each one typically involves. The exact extent comes from the class rules for the ship type and the surveyor attending, so the thickness measurement programme is agreed with the class before work starts.
| Survey | When it falls | What the thickness measurement usually covers |
|---|---|---|
| Annual survey | Every year, within three months of the anniversary date | General examination. Gauging where the surveyor finds suspect areas or where substantial corrosion was recorded at an earlier survey. |
| Intermediate survey | In place of the second or third annual survey | Suspect areas, and on older ships and ESP ships selected ballast and cargo spaces with close-up survey; the extent grows with age. |
| Renewal survey No. 1 | Around 5 years | The first full baseline: suspect areas and selected plating and stiffeners, usually with modest steel renewal. |
| Renewal survey No. 2 | Around 10 years | Wider gauging of deck, bottom and side plating, transverse sections across the cargo area on ESP ships, and more close-up survey. |
| Renewal survey No. 3 | Around 15 years | Extensive gauging of cargo and ballast tank structure and more transverse sections. The survey most likely to turn up steel renewal. |
| Renewal survey No. 4 and later | Around 20 and 25 years | Gauging extended to most structural members in cargo and ballast spaces. Charterers often add a Condition Assessment Programme. |
| Docking survey | Twice in each five-year period | Bottom and side shell, sea chests, rudder and stern area while the hull is dry; suspect bottom plating gauged. |
Egyptian port state control, the Mediterranean ECA and canal traffic
Egypt belongs to the Mediterranean MoU, and the Egyptian Authority for Maritime Safety inspects foreign ships in its ports. For a ship calling at Port Said rather than only transiting, an inspection can raise structural items, and measured thicknesses are what let class and the owner agree whether a repair is needed before sailing. The Suez Canal Authority applies its own rules of navigation and transit requirements, separate from port state control, and the ship's agent is the route for anything that touches them.
With the Mediterranean SOx ECA in force from 1 May 2025, Port Said is the point by which northbound ships must already be burning 0.10% sulphur fuel or running an equivalent scrubber arrangement. Scrubber-fitted ships that switch modes on entering the Mediterranean put their wash-water and overboard piping through hard service, with erosion and corrosion concentrating at bends, valves and shell penetrations. Gauging those lines during a call, and comparing readings over successive calls, gives the superintendent warning before a leak becomes a detention item. Container lines, tanker operators and bulk owners all route through here, so the same scrubber concern appears across ship types.
Since 1 May 2025 the whole Mediterranean has been a sulphur emission control area, so ships calling at Port Said 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.
Typical thickness gauging jobs at Port Said
Port Said work is short and specific. The scenarios below are built around the windows the port actually offers, an anchorage wait before the convoy, a transhipment call at East Port Said or a repair stay at the yard, and the scope is fixed in advance so that the measurement fits the time available, with the reporting format agreed with the superintendent beforehand.
- Re-gauging of a deck area flagged as suspect at the last annual survey on a southbound tanker at the Port Said anchorage, timed to finish before the convoy call.
- Wall-thickness readings on the scrubber overboard and wash-water lines of a container ship working transhipment cargo at East Port Said, compared with the figures from its previous docking.
- Repair-boundary gauging around a damaged shell or deck area at Port Said Shipyard, showing class where plating is sound and how far renewal must extend.
- Pre-purchase gauging of a bulk carrier waiting at anchor for orders, covering deck, hatch covers and accessible ballast tanks so the buyer's superintendent has measured figures.
- Fire-main and ballast line gauging on a ship that has stopped for bunkers and stores, after pinhole leaks on deck lines raised questions about the rest of the system.
How a thickness measurement job runs at Port Said
Most of the work on a Port Said job happens before the team boards: scope, plan and access are settled first, so the time on board goes on measurement.
Most journeys to Port Said start at Cairo International Airport, followed by a road transfer along the line of the canal. At the anchorage the ship's agent arranges the launch and sets the boarding time against the convoy schedule, while access to East Port Said, the harbour berths and the shipyard requires gate passes requested through the agent with passport details in advance. Egyptian visas for the team are obtained before travel from India, so the earlier the expected arrival window is known, the easier it is to place technicians at Port Said when the ship is actually there.
- 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.
Who does the work, and when class approval applies
The inspection team is mobilised from India for each job; nobody is stationed at the port, so mobilisation is planned against the vessel's schedule and visa lead times. Our founder and Responsible NDT Level III, who holds ASNT NDT Level III in UT, RT, MT, PT and VT and has over eleven years of international field experience, plans and supervises the work. Technicians are certified under the company's written practice to ASNT SNT-TC-1A, and the company holds ISO 9001 and ISO 14001 certification.
Thickness measurement that a classification society credits to a class survey has to be carried out by a firm approved by that society under IACS UR Z17. Atlantis is in the process of obtaining UR Z17 approval from DNV, Lloyd's Register and ABS. Until a certificate is issued, the readings we take are for the owner's own decisions, not for credit to a class survey, so tell us the vessel's class and the survey due when you enquire and we set the scope for the right purpose. Owner's and charterer's condition gauging, pre-docking steel estimates, pre-purchase and on-hire or off-hire gauging, and scrubber and piping condition checks between surveys do not need class approval.

Frequently asked questions
Can you gauge a ship during a Suez Canal transit stop at Port Said?
Yes, if the scope fits the time at anchor. A transit stop suits targeted work: re-gauging suspect areas, checking a pipe run or measuring a deck area before class attends. We fix the measurement points from drawings and previous reports before the team boards, and coordinate the boarding time with the agent so the work finishes before the convoy call.
Does Suez Canal ship inspection include thickness measurement?
No. The Suez Canal Authority's checks relate to transit and navigation, and port state control inspections relate to compliance with the conventions; neither measures plate thickness. Gauging is arranged by the owner, usually to answer a question from class, a vetting inspector or the superintendent, and the results go onto the class society's thickness measurement formats.
What does the Mediterranean ECA mean for scrubber piping inspection at Port Said?
Ships entering the Mediterranean from the canal must meet the ECA's 0.10% sulphur limit, so scrubber-fitted ships rely on their systems from Port Said onwards. Wash-water and overboard lines take erosion and corrosion at bends, valves and the shell penetration, and gauging them during a call gives a trend to compare against the readings from the last docking.
Do you offer thickness measurement in Egypt beyond Port Said?
Yes. The same team can attend at Suez and Ain Sokhna at the southern end of the canal, at Alexandria and El Dekheila on the Mediterranean coast, and at Damietta. A ship with gauging split between a transit stop and a later port call can be followed through the country on one mobilisation from India.
Does thickness measurement at Port Said need class approval?
Thickness measurement that a classification society credits to a class survey has to be carried out by a firm approved by that society under IACS UR Z17. Atlantis is in the process of obtaining UR Z17 approval from DNV, Lloyd's Register and ABS. Until a certificate is issued, the readings we take are for the owner's own decisions, not for credit to a class survey, so tell us the vessel's class and the survey due when you enquire and we set the scope for the right purpose. Owner's and charterer's condition gauging, pre-docking steel estimates, pre-purchase and on-hire or off-hire gauging, and scrubber and piping condition checks between surveys do not need class approval.
