Cleanship Marine carries out underwater propeller super polishing at Ajman Port, Ajman. Divers work the blades through a multi-stage sequence to a Class A mirror finish, removing fouling, calcareous deposits and accumulated surface roughness while the vessel lies alongside or at anchor.
The propeller is the highest-leverage surface on any vessel calling at Ajman: it runs at high relative velocity, so roughness there costs disproportionately more than the same roughness spread over the hull. For the general cargo ships and coasters, handysize bulk carriers, barges, dhows and workboats working this port, polishing is the shortest route to a measurable fuel saving.
What it gets you
- Blade roughness removed where it costs the most, at the highest-velocity surface on the vessel
- Propeller efficiency restored between dockings without off-hire
- Cavitation erosion and edge damage documented before it becomes a repair item
- A finish record that supports hull and propeller performance monitoring
Working conditions at Ajman
Ajman is a compact creek-mouth port, sheltered and shallow, working smaller tonnage than its neighbours. Warm, still creek water and long idle periods on the resident coaster and barge fleet mean fouling here is heavy, mixed and frequently past the soft stage — flat bottoms, sea chests and inlet gratings are the recurring problem rather than the vertical sides.

- General cargo ships and coasters · Handysize bulk carriers · Barges, dhows and workboats
What we do at Ajman
- Blade condition assessment covering both faces, the leading and trailing edges and the tips
- Multi-stage polishing sequence worked down to a Class A mirror finish
- Boss, hub and fairing cone cleaned, with rope guard and seal area inspected
- Edge damage, cavitation erosion and any deformation photographed and reported rather than polished over
- Diving permission cleared with Ajman Ports and Customs, and the shaft confirmed immobilised with the master before the dive
- Before-and-after video and a written finish record for the performance file
Planning the window at Ajman
The shamal governs the calendar at Ajman 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 general cargo berths, bulk berths and creek moorings, and which of those a vessel ends up at changes the dive plan more than the season does. Cleanship holds an operating base at Ajman, so we can hold a team ready against a shifting ETA rather than committing travel to a date that may move.
What we typically find at Ajman
Dry bulk handling here puts cargo dust into the water around the berths and anchorage. It settles on horizontal surfaces and packs into sea chest gratings and inlet openings, so inlet and grating clearance is routinely a larger part of the job at Ajman than owners budget for.
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 propeller polishing attendance, wherever the vessel is. Anything outside it is quoted separately and flagged before mobilisation, never added afterwards.
- Deposit removal
- Calcareous growth, shell and hard deposits removed from both blade faces without gouging or scoring the blade surface.
- Progressive polishing
- Successive abrasive grades work the blade from rough to fine, finishing at a Class A mirror surface across the full blade area.
- Edge finishing
- Leading and trailing edges dressed to restore profile and remove the roughness that seeds cavitation.
- Boss and hub
- Boss, hub and rope guard cleaned, with stern tube seal condition inspected and reported.
How we deliver it at Ajman
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Ajman. 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 Ajman Ports and Customs, 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 Ajman
Cleanship holds an operating base at Ajman, so divers, compressors, brush carts and cameras are on the ground rather than in transit. That is the difference between meeting a window and missing it.
- 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 propeller polishing 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 — Propeller Polishing at Ajman
Do you provide propeller polishing at Ajman Port?
Yes. Cleanship Marine works Ajman Port (AEAJM) in Ajman, United Arab Emirates, covering the general cargo berths, bulk berths and creek moorings. We hold an operating base at Ajman, so people and equipment are held locally rather than mobilised against a window.
Can propeller polishing be done while the vessel works cargo at Ajman?
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 Ajman and tell you honestly whether the window you have is enough.
Do you need a diving permit from Ajman Ports and Customs?
Yes, and we obtain it. Diving permission from Ajman Ports and Customs, 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 Ajman?
Visibility at Ajman 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 propeller polishing on at Ajman?
General cargo ships and coasters, Handysize bulk carriers, Barges, dhows and workboats — the traffic at Ajman Port runs to general cargo, aggregates and dry bulk, timber, 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 Ajman?
Cleanship keeps an operating base at Ajman, so response here is fast — the constraint is normally the approvals and the working window rather than getting divers and equipment to the port.
What does propeller polishing at Ajman cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Ajman. 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 Ajman and you get a scoped price, usually the same working day.
