Locating sunken ships and cultural remains

There are approximately three million shipwrecks in the world’s oceans and seas. Some of the wrecks are hundreds of years old and contain priceless, cultural and historical finds or large quantities of minerals. While others are ticking bombs filled with environmentally dangerous poisons, oil or weapons.

RWMT's sub-bottom scanning system

High resolution scanning system

RWMT's system for mapping the bottom sediment layer is powerful enough to locate and identify objects that are not visible using other systems - such as waterlogged wood. 

The technique is based on using ultrasound, which generates high resolution images through vertical echoes. This makes it both environmentally friendly and non-invasive, meaning that it does not harm or impact the marine environment and its animal and plant life.

Archaeological mapping and salvage in marine nature reserve

Since 2020, RWMT has been conducting a scanning and recovery operation commissioned by the State of Ecuador. The operation’s primary objective is to locate and investigate the remnants of wrecks that were identified by an earlier scan of the site. One prerequisite was that the operation was carried out under the UNESCO Conventions for handling cultural remains.

Imaging of the Vasa warship wreck site

In March 2018, Robert Wilson Marine Technologies was asked to assist the Vasa Museum with a survey of the wreck site of the Vasa warship. Our mission focused on finding a missing bronze cannon, known since the 17th century but never found, alongside any other remains of value from the wreck site.
