About the firm
A team that treats every dive like the first.
Ceylon Tech Divers was founded by marine engineers and master divers who refused to compromise. Today, we lead Sri Lanka's most demanding subsea projects with discipline borrowed from offshore energy and craftsmanship rooted in the island we call home.
Engineered for the deep
Saturation systems, hyperbaric chambers, and ROV teams calibrated for operations beyond standard limits.
Marine-safe by design
Every project follows IMCA and HSE protocols, with environmental controls built into every dive plan.
Local roots, global standards
Sri Lankan crews trained in Norway, Singapore and the North Sea — bringing world-class practice home.
Our impact
Numbers earned through thousands of dives.
Every metric represents a project completed, a structure secured, a life saved. We measure what matters.
