Diving into the depths where ocean whispers of history

The Sri Lanka Navy conducted a successful shipwreck expedition from 10 to 17 Mar 25, focusing on historically significant shipwrecks located in the sea area off the coast of Colombo.

The expedition was carried out to document the current state of numerous shipwrecks lying beneath the waves, off Colombo. The survey included the Coal Wreck, Chief Dragon Car Carrier, MV Astoria, MT Nilgiri, Thermopylae Sierra, MV Pecheur Breton, Taprobane East Wreck, SS Worcestershire, Toilet Barge, SS Perseus and some other unidentified wrecks.

Navy divers explored a series of shipwrecks, including the historically significant SS Worcestershire and SS Perseus, both sunk during World War I. Beyond their historical value, the wrecks of the Chief Dragon Car Carrier and Thermopylae Sierra are now functioning as thriving artificial reefs, providing habitats for a variety of marine species.

A total of 14 diving officers and 15 diving sailors participated in this intensive shipwreck expedition. They used both atmospheric air and nitrox air mix as breathing agents, depending on depth and dive duration. This enhanced safety and efficiency, particularly for deeper and more complex dives.

As part of the “Clean Sri Lanka” programme, the Sri Lanka Navy has extended its all-out support to preserve the nation’s maritime heritage, while promoting the island as an appealing tourist destination. These efforts also reflect the Navy’s commitment to enhancing both educational and archaeological value through similar initiatives.
