Registration and documentation

Initially we gathered the positions, made dive, and ROV inspections of the wrecks we discovered, but today we also document many of the wrecks by performing Multibeam and Side scan surveys.
When we consider all the verified wreck positions that we have gathered over the years from fishermen and others in the North Sea, there is now only one position out of three, where you can actually still find remnants of said wreck.

Our experience is that saltwater, corrosion, currents, waves, marine flora and fauna as well as the fishing activities, destroys every wreck lying on the seabed in the North Sea, in a relatively short time.

Wreck remains that are not completely buried/protected in the seabed will disappear with time.

Iron ships strongly degrades and corrodes over a 50 year timespan on the seabed, and after 100 years, only the really heavy iron parts are still to be found, such as machinery, boilers, propellers and propeller shafts. Large beam trawlers contribute to the destruction, and many of the debris is scattered on the seabed, and some are even taken into port as scrap and waste.

Wooden ships disappear completely after just a few years. Shipworms are the main reason for the rapid degradation all the way down to the hulls with copper coating, but powerful trawlers soon destroy the rest. Only the wrecks and parts that are constantly buried in the seabed will be kept relative intact for future generations to find.
