Why In-Water Work

Keep Her Trading, Keep Her Clean

The hull and the propeller get sorted where the vessel sits, so you don't lose a drydock slot or a trading week.

No Drydock, No Deviation

We dive at berth or at anchorage. No haul-out, no slot to wait for, no detour off the schedule.

Burn Less Fuel

A fouled hull and a rough propeller add drag. Clean both in the water and the vessel moves easier.

Class Dates Kept

UWILD and in-water inspections satisfy class without hauling out, so your survey dates hold.

Frequently Asked Questions

Underwater Services in Brazil, Answered

Can you clean the hull and propeller without drydocking?
Yes. Our class-approved divers clean the hull and polish the propeller in the water, at berth or at anchorage, so the vessel keeps trading.
Do you support in-water surveys (UWILD) for class?
Yes. We coordinate UWILD and in-water inspections with class surveyors and your superintendent, with photo and video records for the class file.
Do you handle the diving permits and authority coordination?
Yes. We arrange the diving permits and coordinate with the port authority and the terminal, so the dive happens within the rules.
Which ports can you dive in?
Suape is our base, and we coordinate diving across Brazil's main ports and anchorages. Tell us where the vessel is and we'll arrange it.
What do I get after the job?
A photographic before-and-after report on the hull, the propeller and any area inspected, plus a technical condition note where it's needed.
