Cleanship Marine provides underwater hull cleaning at King Abdullah Port, Makkah Province, working the container terminal berths, RoRo and bulk 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.

King Abdullah Port is Saudi Arabia's newest deep-water container and RoRo gateway, built to serve the industrial city at Rabigh and to take Red Sea transhipment volume. Traffic is liner container and vehicle tonnage on fixed rotations.

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 King Abdullah Port

King Abdullah Port is a modern privately operated terminal north of Jeddah, deep-water, well sheltered and run to high productivity — which means access is a commercial decision by the terminal as much as a port one, and it needs arranging in advance. Red Sea water here is warm and hypersaline with the fouling rate that implies. Alongside work runs year-round; summer heat is the constraint on anything enclosed.

What we do at King Abdullah Port

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 King Abdullah Port and Mawani 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 King Abdullah Port

The northerly Red Sea wind governs the calendar at King Abdullah Port, strongest through the winter and spring. The Red Sea runs a persistent along-axis wind that builds a short chop at the anchorages while the berths stay workable, so the constraint here is almost always the anchorage rather than the season. 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 bulk berths, anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Jeddah (JED), 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 King Abdullah Port

Container tonnage on a fixed rotation shows the familiar pattern: light slime over most of the vertical sides, with the real accumulation in the flat bottom, the bilge keels and the niches where flow is slowest. Those are the areas that cost fuel and the ones a quick clean tends to skip.

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 King Abdullah Port

1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at King Abdullah Port. 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
Access at King Abdullah Port is the terminal operator's decision as much as King Abdullah Port and Mawani's, so both are in the approval chain from the start — a berth-side refusal discovered at the gangway costs the whole attendance. Diving permission, terminal approval and any environmental clearance for in-water work are handled by us, not left with the agent to chase.
3
Mobilisation to King Abdullah Port
Divers, compressors, brush carts and cameras mobilise via Jeddah (JED). Where a vessel is also calling at Jeddah, 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.

Do you provide underwater hull cleaning at King Abdullah Port?

Yes. Cleanship Marine works King Abdullah Port (SAKAC) in Makkah Province, Saudi Arabia, covering the container terminal berths, RoRo and bulk berths, anchorage. Teams mobilise via Jeddah (JED) with the full spread.

Can underwater hull cleaning be done while the vessel works cargo at King Abdullah Port?

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 King Abdullah Port and tell you honestly whether the window you have is enough.

Do you need a diving permit from King Abdullah Port and Mawani?

Yes, and we obtain it. Diving permission from King Abdullah Port and Mawani, 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 King Abdullah Port?

Visibility at King Abdullah Port is moderate, and it drops further around active bulk handling and after heavy rain, and the northerly Red Sea wind 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 King Abdullah Port?

Main-line and feeder container ships, Pure car and truck carriers, Bulk carriers — the traffic at King Abdullah Port runs to containers and transhipment, RoRo and vehicles, dry bulk, 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 King Abdullah Port?

Divers and equipment mobilise via Jeddah (JED). 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 Jeddah or Yanbu, one mobilisation is often sized to cover both.

What does underwater hull cleaning at King Abdullah Port cost?

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