Selected by the Icelandic Maritime Authority, Seawork carried out wreck investigation and body recovery in around 90 metres of water on the edge of the Arctic Circle, working from the coast guard vessel Thor using surface-gas techniques over a two-week operation.
On the River Severn, an area known for the Severn Bore, Seawork recovered an award-winning narrowboat that had sunk and filled with silt, doubling its weight.
Seawork recovered a 65-tonne dredger from a 30-metre-deep sand quarry, craning in a modular pontoon and workboat, removing dredge pipe, cables and walkways, and using flotation bags for the main lift.
Instructed at short notice, Seawork surveyed and measured hatch covers, manufactured blow tubes and air fittings, and used controlled de-ballasting with compressed air to refloat a sunken linkspan pontoon.
Near the Esso Fawley Refinery and BP Hamble jetty, Seawork removed a sunken vessel, managing pollution control, lift ashore, method statements, permissions and full marine support.
A core of highly experienced personnel assist major salvage companies worldwide, providing equipment and personnel, or personnel only, across the UK, Europe, Mexico, Iceland, Chile, Colombia, Africa, Italy and Malaysia.
Working from the DSV Curtis Marshall, Seawork replaced tide-flex duckbill valves on an outfall in 25 metres of water, completing a full underwater video inspection for the client's records.
Seawork provided diving and lifting operations to install a Tideflex valve plate assembly to a culvert discharge, including drilling, resin-set fixings and removal of previous steelwork.
After a mass concrete plug had cured, Seawork returned to install anti-vortex plates and pipework, delivering the precision accuracy the design required.
Called late in the day, Seawork removed 18 anodes from the rudder and stern post of a car carrier and refitted new ones within a short window before the vessel sailed, with a full video survey and report.
Seawork completed a full inspection of a marker pile warning of a large submerged object, including ultrasonic thickness testing, video and a report with recommendations.
