Vasilikos, Cyprus: Thickness Measurement for Tankers and Energy Port Callers
Vasilikos is Cyprus's energy port, on the south coast between Limassol and Larnaca. Fuel tankers, cargo ships and vessels linked to the island's power and gas projects call at its terminals, where rules are strict and berths are working berths. We mobilise a team from India to the ship, and gauging is planned around the terminal's permit system and the ship's cargo operations.
Work inside a permit system
Terminal stays are governed by permits to work. We send crew details and a written scope ahead, and shape the plan around cargo transfer so gauging does not hold up discharge or loading.
Deck and piping on tankers
On a working tanker, deck plating, deck piping and ballast tanks are the realistic gauging targets. These are also the areas that vetting inspectors and charterers ask about first.
Combines with Limassol and Larnaca
Vasilikos lies a short drive from both neighbouring ports. A single mobilisation can cover a tanker here, a ship at Limassol and an anchorage call off Larnaca across consecutive days.

ExploreVasilikos: the island's energy port
Vasilikos lies on the south coast of Cyprus, roughly midway between Limassol and Larnaca, in an area that has become the centre of the island's energy and heavy industry. The port is administered by the Cyprus Ports Authority and is built around offshore and jetty berths that serve the major industrial installations behind it, including the island's largest power station, fuel storage and a cement works. Because the facilities are industrial rather than commercial in the usual sense, the shipping that calls is closely tied to specific operations and cargoes.
The vessels that visit are mostly tankers and cargo ships. Product tankers discharge fuel for the island's power generation, aviation and road transport, bulk and general cargo ships bring industrial inputs, and vessels connected to the island's gas development and energy projects call from time to time. Heavy-lift and project ships appear when large equipment is delivered. Many of these ships are on regular regional rotations or serve the island under contract, and stays at the berths range from a day to a few days depending on cargo, tides of operations and berth availability.
The surrounding waters are generally open and exposed to southerly and south-westerly weather, so sea state can interrupt boat transfers and sometimes berthing. Ships waiting for a berth lie off the coast, and the agent arranges launch access when conditions allow. Cyprus has no large repair yard, so ships needing steel renewal are repaired in Greek, Turkish or other yards, and gauging at Vasilikos works best as a measured condition check or as the first step of a docking plan prepared in advance.
Where gauging can be carried out at Vasilikos
Work at the berths is limited by the terminal's permit-to-work system and by the ship's cargo operations. On a product tanker alongside, the realistic scope is deck plating, deck piping and ballast tanks, and work may pause during cargo transfer or hot-work restrictions. Cargo ships and project vessels offer holds, hatch covers and deck areas once cargo is discharged and the terminal allows access. Ro-ro and heavy-lift ships can be gauged on deck and in ballast spaces during longer berth stays.
Ships waiting offshore can be boarded by launch for pre-docking or condition gauging, subject to weather and the master's decision, and the same applies to ships anchored off nearby Limassol and Larnaca. Because gauging at a working energy berth needs the operator's agreement, we ask the agent and the ship's manager early which permits and escorts are required. For anyone arranging ship inspection in Cyprus, Vasilikos is best treated as one stop in a Cyprus programme rather than a stand-alone job.
- Tanker berths — deck plating, deck piping and ballast tank readings on product tankers within the terminal's permit rules
- Cargo and project berths — hold, hatch cover and deck gauging on cargo ships and heavy-lift vessels once cargo is cleared
- Offshore waiting area — pre-docking and condition gauging, boarded by launch when conditions allow
- Limassol port and anchorage — short drive by road for combined programmes within one mobilisation
- Larnaca Bay anchorage — a second nearby location for ships waiting for orders or changing crew
Thickness measurement through the survey cycle at Vasilikos
Every renewal survey asks for more thickness measurement than the last, and for oil tankers, chemical tankers and bulk carriers the ESP Code adds close-up survey on top. The table is the usual shape of the work; the class rules and the surveyor set the exact extent, which is why the measurement plan for a job at Vasilikos is agreed in writing before mobilisation.
| 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. |
Cyprus port state control and energy-port rules
Port state control in Cyprus is carried out under the supervision of the Department of Merchant Shipping, which sits within the Deputy Ministry of Shipping, and the country takes part in both the Paris MoU and the Mediterranean MoU. The Mediterranean emission control area for sulphur, in force since 1 May 2025, applies around Cyprus. EU ETS has covered shipping since 2024 and FuelEU Maritime since 2025, and both apply to voyages calling at Vasilikos. Ships entering EU ports should also hold an Inventory of Hazardous Materials.
The energy-port setting adds its own conditions. Tanker terminals normally require advance details of everyone boarding, safety briefings, hot-work and entry permits, and sometimes escorts, and these requirements apply to inspection teams as much as to visitors. Owners and charterers of tankers calling here often run their own vetting programmes, and a gauging report that ties deck, piping and ballast tank readings to previous survey records helps the superintendent answer vetting questions directly.
Since 1 May 2025 the whole Mediterranean has been a sulphur emission control area, so ships calling at Vasilikos 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 Vasilikos
Jobs at Vasilikos are short, defined and set up in advance. The superintendent names the spaces and the question, the terminal permits and escorts are arranged by the agent, and we work through the list during the berth stay, passing readings back as each area is completed.
- Deck plating and deck piping readings on a product tanker alongside the fuel berth, prepared for an oil-major vetting inspection.
- Ballast tank gauging on a chemical tanker during a Cyprus call, compared with the last renewal survey readings to see how known wastage has progressed.
- Hatch cover, coaming and deck gauging on a general cargo ship delivering industrial supplies, ahead of a new charter.
- Pre-purchase condition gauging on a coastal tanker with the buyer's superintendent attending, covering deck, piping and ballast spaces.
- Scrubber overboard piping inspection on a bulk carrier at the berth after a discharge flange was reported weeping.
How a thickness measurement job runs at Vasilikos
The sequence for a thickness measurement job at Vasilikos is short and written down, so the yard, the surveyor and the superintendent know who arranges what.
The team flies into Larnaca International Airport, the nearest gateway, and reaches Vasilikos by road along the south coast; Paphos is an alternative. Berth access under ISPS, terminal permits, safety briefings and any launch boarding are arranged through the ship's agent from the crew list, technician certificates and equipment details we send beforehand. Indian nationals need entry permission for Cyprus, so we confirm the current route for each technician when the job is scoped. Because tanker calls here can change at short notice, telling us early about likely visits lets us prepare visas in advance.
- 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
We send the team from India to the ship for each job rather than keeping staff at the port, and plan the mobilisation around visas and the vessel's itinerary. The work is planned and supervised by the founder, our Responsible NDT Level III (ASNT NDT Level III in UT, RT, MT, PT and VT, with more than eleven years of international field experience). Technicians hold certification under the company's written practice to ASNT SNT-TC-1A; Atlantis is ISO 9001 and ISO 14001 certified.
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
What can be gauged on a tanker at Vasilikos?
Normally the deck, its piping and the ballast tanks, under the terminal's own permit system. Cargo transfer may pause the work, and hot-work or entry restrictions can apply. The agent confirms what is allowed, and we plan readings so they fit around operations instead of delaying them.
What information does the terminal need before we arrive?
Typically a crew list with passport details, technician certificates, an equipment list and a written scope, sent through the agent ahead of the call. Some terminals also require a safety briefing and an escort. We send our documents as soon as the job is confirmed, so the permit can be issued before the ship berths.
Is there a drydock in Cyprus for steel renewal?
Not on the scale needed for major hull work. Ships needing steel renewal normally go to yards in Greece, Turkey or elsewhere in the Mediterranean. Gauging at Vasilikos works as preparation: measured readings give the owner a steel estimate, help compare yard offers and let plate be ordered before the ship sails.
Can ships waiting offshore be gauged?
Yes, when weather and the master allow. The agent arranges a launch and we board with portable equipment. The coast is exposed to southerly weather, so transfers can be cancelled at short notice. Tanks need ventilating, testing and certifying before entry, and we leave slack in the plan.
Can one trip cover Vasilikos, Limassol and Larnaca?
Yes. Vasilikos sits between the other two on the south coast, so a combined programme saves repeated travel. Send us the vessels and windows, and we will plan the order of jobs, the visa period and the agent arrangements as one programme.
Does thickness measurement at Vasilikos 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.
