DOF Subsea is a leading provider of subsea services to the Oil and Gas industry. They customise a fleet of sea vessels to provide services to the Oil and Gas industry. We visited their offices in Aberdeen to deliver our our welding training course. Welding is used extensively and they were very grateful for the spreadsheet tools from the ExcelCalcs website which make it easy to check the strength of welds with accuracy and speed. These tools will help them to minimise the size of welds to reduce the time it takes to customise their vessels thereby freeing up these expensive assets back into useful service.
