The Professional Diving Academy’s strategic partnership with Hydratight ensures that delivery of our Subsea Bolted Joint Integrity Course, is to the very highest industry standards. Commercial Divers and Dive Supervisors who undertake this course, will graduate with enhanced theoretical and practical understanding of the safe working procedures that must be adhered to when operating high pressure hydraulic bolt tensioning equipment in the subsurface environment. The training programme is also greatly beneficial for stakeholders, by reducing the potential for downtime through procedural errors made by unqualified personnel operating complex flange assembly/disassembly equipment on subsurface assets.
