Simplified Wreck Survey

Underwater shipwreck details for the ZELO and MERKUR wrecks located in the Irish Sea at coordinates 51 21.975 N, 3 16.131 W. These two shipwrecks sit in close proximity and are difficult to distinguish from each other, though both remain moderately well defined and intact. The wreck site is situated in a general water depth of 10 meters, with a least depth of 5.28 meters over the wreckage and a scour depth of 0.76 meters. The combined wreckage dimensions are approximately 129.7 meters in length and 36.2 meters in width, with a height of 4.7 meters. The orientation of the wreckage is recorded at 082/262 degrees and 051/235 degrees. Previous surveys by HMS Woodlark and Land & Marine Engineering Ltd have identified the site as a dispersed wreck field with turbulence noted around the structures.
