Hull Cleaning, Propeller Polishing and Underwater Inspection

Full hull cleaning, propeller polishing and underwater inspections at Batangas and other Philippine ports, with before and after photo reports for owners.

Hull cleaning removes marine growth from a ship's underwater hull so the vessel burns less fuel on the next passage. V. Faytaren Shipping Agency arranges full hull cleaning, propeller polishing and underwater inspections at Batangas and other Philippine ports, with a photo report before and after every job.

See the work: Full hull cleaning and propeller polishing and Underwater inspection of a starboard anchor chain.

What our hull cleaning service covers

Warm tropical water is good for marine growth. Weed, slime, tubeworms and barnacles build up on the hull, especially when a ship waits at anchor for weeks, and the result is more drag and a higher fuel bill. Charterers may also raise performance claims when a fouled hull slows the vessel down.

Cleaning the hull while the vessel is already in port saves a separate stop. We deploy the diving team, schedule the work around cargo operations or waiting time, handle the permits that port authorities may require for underwater work, and agree safety measures with the master, such as isolating sea chests and the propeller.

Every job ends with a report the master and your technical department can use: fouling type, thickness and coverage by area, the condition of shell plating, weld seams, bilge keels, anodes and gratings, and photos of each area before and after. When something below the waterline needs a closer look, such as an anchor chain or a fouled propeller, the same team carries out an underwater inspection and tells you plainly what they found.

What we handle

  • Full underwater hull cleaning at berth or anchorage
  • Propeller polishing (Rubert scale grade A on our last job)
  • Rudder, sea chest gratings and boot top cleaning
  • Hull condition survey: plating, welds, bilge keels, anodes
  • Underwater inspection of anchor chains and fittings
  • Before and after photos and video for every area
  • Permits and safety coordination with the master
  • Written report submitted to the master before sign-off

How it works

  1. Request

    Share the vessel details, location and what you want cleaned or inspected.

  2. Planning

    We line up the divers, permits and a time slot that suits the port stay.

  3. Dive work

    The team records each area before cleaning, cleans it, then records it again.

  4. Report

    The master reviews the photos and video, then you receive the full report.

Frequently asked questions

Why clean the hull during a port call?

Marine growth increases drag and fuel use. Cleaning while the vessel is already in port avoids a separate stop and can help with charter party performance.

Do you need a permit for hull cleaning?

Underwater work may need approval from the port authorities. We check the requirement for your location and handle the paperwork.

Can the propeller be polished at the same time?

Yes. On our most recent full hull job at Batangas, the propeller was polished to Rubert scale grade A during the same two-day operation.

What does the report include?

Fouling type, thickness and coverage by area, the condition of plating, welds, bilge keels, anodes and gratings, plus before and after photos of every area. The master reviews the files before signing the completion report.

Can you inspect an anchor chain underwater?

Yes. Divers can follow the chain down to check the stud links and record depths with gauges and photos. Dives stop at safe limits, and the report recommends next steps such as underwater cutting when a chain cannot be recovered.

Full hull cleaning and propeller polishing at Sta. Clara anchorage, Batangas

A 186-metre bulk carrier came to us with heavy fouling after time at anchor. Over two days our dive team cleaned the entire underwater hull, polished the propeller, and surveyed the hull condition area by area.

Size
186 m LOA, 26,094 gross tonnage
Location
Sta. Clara Anchorage Area, Batangas
Conditions
Calm sea, 0.2 knot current, 3 m visibility
Scope
Full hull cleaning, propeller polishing, visual inspection, photo and video survey

What the divers found and did

  • Heavy fouling (severity C) across the hull: 85 to 90 percent coverage, up to 35 mm thick on the flat bottom.
  • Growth included algae, sea grass, slime, tubeworms, goose barnacles and acorn barnacles.
  • All underwater areas, including the rudder, sea chests and boot top, were cleaned with designated equipment.
  • The four-blade propeller was polished to Rubert scale grade A.
  • Shell plating, weld seams and both bilge keels (three segments each side) were found in good condition, with no mechanical damage.
  • Sea chest gratings were secure. Sacrificial anodes were found fully and uniformly depleted and reported to the master.
  • All photos and videos were reviewed by the master before the completion report was signed.

Underwater inspection of a starboard anchor chain

After the same vessel tried to heave up its starboard anchor without success, our divers went down to check the stud link chain and find where it stood. The dive began at 1000 hours and was completed by 1115.

Vessel
The same bulk carrier
Task
Inspect the starboard stud link anchor chain
Water depth
About 64 m from waterline to bottom
Timing
Divers on site 0900, dive 1000 to 1115

What the divers found and did

  • Shot number 3 of the stud link chain was found 7 m below the waterline, and shot number 2 at 34 m.
  • The underwater camera stopped working at 48.5 m.
  • The dive was stopped at 50 m for safety: the current was strong enough to drag the divers, and going past 60 m would have needed decompression stops.
  • Recommendation: review the findings with the vessel's superintendent and master, then cut the stud link chain underwater to release the snapped anchor, since the entanglement was too deep to clear.
