In-Water Hull Cleaning

Trident Services provides professional in-water hull cleaning for vessels operating across Singapore and the Southeast Asia region.

Our commercial dive teams remove marine growth from the underwater hull while the vessel remains afloat, restoring smooth hull conditions, improving fuel efficiency, and supporting biosecurity compliance—all without the need for dry docking.

Why Hull Cleaning Matters

Marine biofouling on a vessel’s hull increases hydrodynamic drag, leading to higher fuel consumption, increased emissions, and the potential transfer of invasive species across international borders.
Regular in-water hull cleaning helps to:

  • Reduce fuel costs and emissions
  • Restore vessel speed and overall performance
  • Support biosecurity compliance for regulated ports and jurisdictions
  • Extend coating life and help reduce corrosion

What We Clean

  • Full underwater hull surfaces (flat bottom, vertical sides, boot-top)
  • Niche areas (sea chests, gratings, bilge keels, thruster tunnels)
  • Propellers and running gear
  • Rudders and stern areas

All cleaning is matched to the vessel’s coating type to avoid damage to the anti-fouling system.

Our Cleaning Methods

Diver-based cleaning

For precision work and sensitive or confined areas.

Controlled tooling & brush systems

For large flat hull surfaces.

Hybrid ROV + Diver cleaning

For large hulls, combining ROV efficiency with diver precision.

Debris capture options

To support environmental and biofouling management requirements.

Compliance and Biosecurity

For vessels calling New Zealand, Australia, and other regulated ports, hull and niche cleanliness is a compliance requirement—not just a performance gain.

We help operators meet clean-hull expectations and provide full photo and video documentation for maintenance records and inspection review.

Stay Compliant. Stay Operational.

Proactive hull maintenance ensures smooth port entry — every time.
