Inspection

Inspection is a data-gathering task which helps to assess the structural integrity of a structure.
Inspection diving is not only based on visual methods such as photography, video and the diver’s own eyes, but also includes specialised activities such as:

  • Non destructive testing (NDT);

  • Corrosion damage inspection;

  • Cathodic protection surveys (anode inspection and electrical potential measurement)

  • Marine growth inspection and removal;

  • Scour and stability inspections;

  • Debris inspection and removal.

NDT requires considerable skill in operation and experience in interpretation, therefore all the diving personnel involved in NDT have received a sound training and a recognised qualification, supported by practical training and experience. Inspection projects are followed by a dedicated team of engineers qualified as underwater inspection controllers (CSWIP 3.4U), whose responsibility is to plan and co-ordinate the subsea inspection programme.

RANA owns state of the art equipment for the execution of non destructive testing, including:

  • Alternate Current Field Measurement (ACFM)

  • Magnetic Particle Inspection (MPI)

  • Ultrasonic Thickness Measurement (UT)

  • Cathodic Potential Gauges (CP)

  • Ultrasonic Flaw Detection and other systems

Maintenance and Repair

Maintenance and repair include a wide variety of tasks and skills, from cleaning to cutting and burning, pipeline connections, pipeline stabilisation, valves operating, air lifting, rigging, underwater grouting and so on.
