Underwater Inspections, Hull Cleaning, Propeller Polishing and Marine Support Services

Professional Commercial Diving Services

Commercial diving services play a vital role in maintaining vessel performance, reducing operational costs and identifying underwater issues before they become major problems.

Group 3A provides professional commercial diving support for shipowners, managers, charterers, insurers and P&I Clubs. Through our network of qualified diving specialists and trusted partners, we assist clients with underwater inspections, hull cleaning, propeller polishing, damage assessments and emergency underwater operations.

While we can assist clients worldwide, Thailand remains one of our primary areas of operation, with regular attendance arranged at major ports, anchorages and offshore locations throughout the country.

Why Commercial Diving Services Matter

Unexpected underwater issues can lead to:

  • Increased fuel consumption
  • Reduced vessel performance
  • Off-hire disputes
  • Delays to commercial operations
  • Insurance claims
  • Costly dry-docking decisions

 

Commercial diving inspections provide a fast and cost-effective way to assess underwater conditions while minimising disruption to vessel schedules.

Our objective is simple:

Provide reliable underwater information so clients can make informed operational decisions quickly and confidently.

Benefits of Hull Cleaning and Propeller Polishing

Marine growth can significantly increase resistance through the water and negatively impact vessel performance.

Regular underwater maintenance may help:

  • Improve fuel efficiency
  • Reduce operating costs
  • Maintain vessel speed
  • Improve charter party performance
  • Reduce greenhouse gas emissions
