Cleanship Marine carries out underwater propeller super polishing at Kpémé Port, Maritime Region. 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 at the anchorage.
The propeller is the highest-leverage surface on any vessel calling at Kpémé: it runs at high relative velocity, so roughness there costs disproportionately more than the same roughness spread over the hull. For the handysize and supramax bulk carriers, support and mooring craft 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 Kpémé
Kpémé loads over an offshore jetty with no enclosed basin, so there is no shelter at all and the Atlantic swell decides whether work happens. Vessels lie exposed for the whole loading operation, which makes this one of the more demanding in-water working environments on the coverage list and one where the window has to be taken when it appears rather than booked. Water is warm and reasonably clear away from the loading point.

What we do at Kpémé
- 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 Société Nouvelle des Phosphates du Togo, 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 Kpémé
The Atlantic swell and the rains governs the calendar at Kpémé Port, with the heaviest rain from May to October and swell running year-round. The swell here is long-period Atlantic ground swell rather than wind-driven sea, so it reaches the anchorages on days that look calm from the bridge and it is the single biggest cause of a lost in-water window on this coast. Work here is done with the vessel riding to her anchor, so the dive plan is built around sea state and swell rather than a berth slot, and the team stands by for a workable window rather than a scheduled one.
Work is taken at the offshore loading jetty and outer anchorage, and which of those a vessel ends up at changes the dive plan more than the season does. Teams mobilise via Lomé (LFW), 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 Kpémé
The working fleet here spends most of its life at low speed in warm water, so growth is heavy, mixed and reaches the hard calcareous stage sooner than on deep-sea tonnage. Left too long it starts damaging the coating rather than just slowing the vessel.
Vessels here sit at anchor for long periods, and a stationary hull in warm water is the ideal fouling substrate. The heaviest growth we lift at this port is almost always off a vessel that has been waiting rather than working.
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 Kpémé
- 1
Scope and vessel details
Tell us the vessel, her particulars, the coating specification and the window at Kpémé. 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 Kpémé Port is the terminal operator's decision as much as Société Nouvelle des Phosphates du Togo'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 Kpémé
Divers, compressors, brush carts and cameras mobilise via Lomé (LFW). Where a vessel is also calling at Lomé, 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 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 Kpémé
Do you provide propeller polishing at Kpémé Port?
Yes. Cleanship Marine works Kpémé Port (TGKPE) in Maritime Region, Togo, covering the offshore loading jetty and outer anchorage. Teams mobilise via Lomé (LFW) with the full spread.
Can propeller polishing be done while the vessel works cargo at Kpémé?
Yes — it is the norm here, because the work is done at anchor rather than at a berth. Barge operations carry on around the dive, with the working side agreed with the master beforehand. The vessel stays on hire throughout, and there is no diversion and no dry dock. We scope against the conditions at Kpémé and tell you honestly whether the window you have is enough.
Do you need a diving permit from Société Nouvelle des Phosphates du Togo?
Yes, and we obtain it. Diving permission from Société Nouvelle des Phosphates du Togo, 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 Kpémé?
Visibility at Kpémé Port is generally workable outside the monsoon, though cargo dust from lighterage reduces it sharply near an active transfer, and the Atlantic swell and the rains 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 Kpémé?
Handysize and Supramax bulk carriers, Support and mooring craft — the traffic at Kpémé Port runs to phosphate rock, 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 Kpémé?
Divers and equipment mobilise via Lomé (LFW). 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 Lomé or Cotonou, one mobilisation is often sized to cover both.
What does propeller polishing at Kpémé cost?
It depends on the vessel's dimensions and wetted area, the fouling state found, the coating specification and the working window available at Kpémé. 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 Kpémé and you get a scoped price, usually the same working day.
