Cleanship Marine provides underwater hull cleaning at Jebel Ali Port, Dubai, working the container terminal berths, RoRo and general cargo berths. Commercial dive teams remove slime, weed and shell growth from the vertical sides, flat bottom, bilge keels, sea chests and niche areas with the vessel afloat and on hire — no dry dock, no diversion, no off-hire.
Jebel Ali is the largest container port in the Middle East and the region's main transhipment and free-zone gateway, working containers, vehicles, project cargo and liquid bulk. Liner tonnage calls to fixed rotations, which makes hull cleaning and propeller polishing a scheduled maintenance item rather than a response to a speed complaint.
What it gets you
- Hydrodynamic smoothness restored before fouling reaches the calcareous stage that damages coating
- Fuel and emissions penalty from drag reduced without taking the vessel off hire
- Documented condition record for the technical file and the next docking specification
- Sea chests and inlets cleared, protecting cooling water flow
Working conditions at Jebel Ali
Jebel Ali is a large artificial harbour and thoroughly sheltered, so in-water work runs alongside for most of the year and the berth window, not the weather, is the constraint. What the Gulf takes back is biological: shallow, hot, hypersaline water grows fouling faster here than almost anywhere the fleet trades, and a hull that looked acceptable at the last call can be materially fouled three months later. Visibility in the basin is moderate and drops around dredging and bunkering activity.

What we do at Jebel Ali
- Pre-clean fouling survey to establish coverage, growth type and coating condition before any tool touches the hull
- Brush cart cleaning of the flat bottom and vertical sides, with brush hardness selected against your antifouling specification
- Hand cleaning of bilge keels, rudder, stern frame, thruster tunnels, anodes and the niches a cart cannot follow
- Sea chest gratings and inlet openings cleared of growth and debris to restore cooling water flow
- Diving permission cleared with DP World and the Dubai Maritime Authority and the terminal before mobilisation
- Before-and-after video and stills, with a written report on coating condition and anode wastage
Planning the window at Jebel Ali
The shamal governs the calendar at Jebel Ali Port, through the winter months and again in early summer. The shamal is a wind and sea-state problem rather than a rain one: it builds short, steep seas across the shallow Gulf that stop anchorage work while berths stay usable. Because the harbour is sheltered, work here normally runs alongside or at a protected anchorage and can proceed in parallel with cargo operations rather than competing with them for the berth window.
Work is taken at the container terminal berths, RoRo and general cargo berths, liquid bulk berths, outer anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Dubai (DXB) or Al Maktoum (DWC), so give us the ETA as early as you have it — the travel is the flexible part, the approvals and the working window are not.
What we typically find at Jebel Ali
Liquid and gas tonnage here spends long stretches at the terminal or waiting for a slot, so growth tends to be even and well established across the hull rather than patchy — heavier than the trading pattern suggests, and further along than a speed report alone would indicate.
Shelter is a mixed blessing for a hull. The same calm that makes the port easy to work in is still water, and still water grows fouling faster than an exposed berth does.
Standard scope of work
Included as standard on every underwater hull cleaning attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Fouling survey
- A pre-clean dive establishes fouling type, coverage and severity, and confirms coating condition so the correct tooling is selected.
- Flat bottom and vertical sides
- Brush cart cleaning of large areas, removing slime, weed and shell growth to restore surface smoothness.
- Niche areas
- Hand cleaning of bilge keels, bow thruster tunnels, rudder, stern frame, anodes and other niche areas where fouling concentrates.
- Sea chests and gratings
- Sea chest gratings and inlet openings cleared of growth and debris to restore cooling water flow.
- Documentation
- Underwater video and stills before and after, with a written report covering coating condition and anode wastage.
How we deliver it at Jebel Ali
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Jebel Ali. We come back with a defined scope, a crew size and a duration we will stand behind. Where the conditions here will not support what has been asked for, we say so at this stage rather than after mobilisation.
- 2
Permits and approvals
Diving permission is obtained from DP World and the Dubai Maritime Authority, along with terminal approval where the berth requires it and any environmental clearance for in-water work. This is handled by us, not left with the agent to chase.
- 3
Mobilisation to Jebel Ali
Divers, compressors, brush carts and cameras mobilise via Dubai (DXB) or Al Maktoum (DWC). Where a vessel is also calling at Port Rashid, one mobilisation is normally sized to cover both.
- 4
Safety setup and the dive
The vessel is secured for diving — main engine, shaft and thrusters immobilised, sea suctions confirmed shut, permit agreed with the master. Teams work under surface supervision with continuous diver communications and video throughout.
- 5
Report and handover
A completion report covering underwater hull cleaning is issued with before-and-after imagery, coating and anode condition and anything found that you should know about. The findings are discussed with the vessel rather than emailed and forgotten.

Frequently asked — Underwater Hull Cleaning at Jebel Ali
Do you provide underwater hull cleaning at Jebel Ali Port?
Yes. Cleanship Marine works Jebel Ali Port (AEJEA) in Dubai, United Arab Emirates, covering the container terminal berths, RoRo and general cargo berths, liquid bulk berths, outer anchorage. Teams mobilise via Dubai (DXB) or Al Maktoum (DWC) with the full spread.
Can underwater hull cleaning be done while the vessel works cargo at Jebel Ali?
Yes, in most cases. The harbour is sheltered enough that divers work alongside while cargo operations continue, and neither holds the other up. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Jebel Ali and tell you honestly whether the window you have is enough.
Do you need a diving permit from DP World and the Dubai Maritime Authority?
Yes, and we obtain it. Diving permission from DP World and the Dubai Maritime Authority, terminal approval where the berth requires it, and any environmental clearance for in-water work are arranged as part of the job rather than left with the agent. The master's permit to work and the immobilisation of machinery are agreed on board before anyone enters the water.
What is underwater visibility like at Jebel Ali?
Visibility at Jebel Ali Port is moderate, and it drops further around active bulk handling and after heavy rain, and the shamal sets the outer limits of the calendar. How the tide and sea state shape the dive plan is set out in full in the working-conditions section on this page.
Which vessels do you carry out underwater hull cleaning on at Jebel Ali?
Main-line and feeder container ships, Pure car and truck carriers, General cargo and project vessels, Offshore support vessels — the traffic at Jebel Ali Port runs to containers, roro and vehicles, project cargo, so those are the profiles we see most. The scope is sized to the vessel, not to a standard package.
How quickly can a team mobilise to Jebel Ali?
Divers and equipment mobilise via Dubai (DXB) or Al Maktoum (DWC). Give us the ETA and the window and we will confirm what is achievable rather than promise a date we cannot hold. Where the vessel also calls at Port Rashid or Sharjah, one mobilisation is often sized to cover both.
What does underwater hull cleaning at Jebel Ali cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Jebel Ali. We would rather scope it properly and give you a specific figure than quote a headline rate that changes once the work starts. Send the details and the window at Jebel Ali and you get a scoped price, usually the same working day.
