Jumbo Subsea buoys at Ichthys field

Resinex in the second part of 2020 supplied to McDermott Australia two large subsea buoys for the mega Australian gas field Ichthys. The buoys have a diameter of 4,3 meters, a net buoyancy 65 tons and 55 tons, and a height of 10 and 9 meters respectively. They are composed of various modules in linear polyethylene filled with high-density polyurethane foam and macrospheres. This allows a great resistance underwater.

Besides the underwater pressure tests, a test for 98 tons was carried out to assess the tensile strength of the steel part, and a lot of attention was also paid to corrosion with the use of protective galvanization and paint. We made also an impact and a pressure test. The buoys will be used during the installation of equipment at a water depth of 300 meters.
