We have designed a system that can assemble a SPO compact flange subsea with the use of a ROV. The compact flange will be assembled using hydraulic bolt turning tools, and have automatically nut entering capabilities. Bolts will be pre-loaded using hydraulic tension nuts, and the seal ring inside the flange is made replaceable.
