Cleanship Marine provides underwater hull cleaning at Ras Al Khaimah Port, Ras Al Khaimah, working the bulk berths 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.

Ras Al Khaimah works aggregates, cement and ceramics for the regional construction trade through the emirate's older port, alongside the larger bulk operation at Saqr Port a short distance up the coast. Traffic is Handysize bulk tonnage and coasters on short regional voyages.

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 Ras Al Khaimah

Ras Al Khaimah is a sheltered Gulf port working smaller bulk and general cargo tonnage, so alongside work is practical year-round with the winter shamal the main interruption at the anchorage. Water is shallow, hot and hypersaline, and the aggregate trade puts a constant film of rock dust into the basin that settles into sea chest gratings and inlet openings. Inlet clearance is a bigger part of the job here than the fouling itself.

What we do at Ras Al Khaimah

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 RAK Ports 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 Ras Al Khaimah

The shamal governs the calendar at Ras Al Khaimah 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 bulk berths, general cargo berths and anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Ras Al Khaimah (RKT) or Dubai (DXB), 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 Ras Al Khaimah

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 Ras Al Khaimah 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 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 Ras Al Khaimah

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Ras Al Khaimah. 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 RAK Ports, 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 Ras Al Khaimah
Divers, compressors, brush carts and cameras mobilise via Ras Al Khaimah (RKT) or Dubai (DXB). Where a vessel is also calling at Mina Saqr, 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 Ras Al Khaimah

Do you provide underwater hull cleaning at Ras Al Khaimah Port?

Yes. Cleanship Marine works Ras Al Khaimah Port (AERKT) in Ras Al Khaimah, United Arab Emirates, covering the bulk berths, general cargo berths and anchorage. Teams mobilise via Ras Al Khaimah (RKT) or Dubai (DXB) with the full spread.

Can underwater hull cleaning be done while the vessel works cargo at Ras Al Khaimah?

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 Ras Al Khaimah and tell you honestly whether the window you have is enough.

Do you need a diving permit from RAK Ports?

Yes, and we obtain it. Diving permission from RAK Ports, 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 Ras Al Khaimah?

Visibility at Ras Al Khaimah 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 Ras Al Khaimah?

Handysize bulk carriers, General cargo ships and coasters, Barges and tugs — the traffic at Ras Al Khaimah Port runs to aggregates and dry bulk, cement and clinker, general 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 Ras Al Khaimah?

Divers and equipment mobilise via Ras Al Khaimah (RKT) or Dubai (DXB). 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 Mina Saqr or Umm Al Quwain, one mobilisation is often sized to cover both.

What does underwater hull cleaning at Ras Al Khaimah cost?

It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Ras Al Khaimah. 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 Ras Al Khaimah and you get a scoped price, usually the same working day.
