The Mk 2 consists of a traction module and attached to this are various work packages. The work packages can be attached either above, or below, or both, to the Traction Module. This means that it would be possible to clean, perform Close Visual Inspection, make an NDT survey, drill a crack to stop it propagating and then recoat the surface all in one operation. This makes the Roto Climber Mk 2 unequalled in the world today.

The Mk 2 is equipped with sensors to measure distance moved from starting point in a vertical direction, sensors to measure distance moved by the carriage in an horizontal direction and a gyro to determine a North/South Orientation. This enables the Mk 2 to be able to exactly replicate its movements and so return to a defect location with very little difficulty.

The Mk 2 is equipped with dual cleaning heads that are Stoneage Barracuda nozzles (Model BC-H9-C) that deliver seawater up to a pressure of 3,000 Bars and a flow of up to 28 Litres per minute per nozzle. (Both parameters are adjustable). These nozzles use UHP water, to clean to a surface finish of SA 2.5

Alternatively the Mk 2 can be equipped with cleaning brushes, or scrapers if the surface to be cleaned is not suitable for cleaning by UHP water.

The Mk 2 is equipped with a Cygnus Dive Mk 2 Ultra Sonic Thickness Gauge that can measure wall thickness loss without removing coatings.

The Mk 2 can also be equipped with a phased array system

The Mk 2 can Also be equipped with a UHP abrasive cutting head to cut through steel. This maybe needed on a conductor when a directional well needs to be cut through an existing vertical casing. It could also be required when removing a section of corroded casing or pipe. Due to the controllability of the Roto Climber and its modules, it is possible to cut a circle or an arc in the pipe, so that stresses are minimised.

The Mk 2 can Also have a drilling module attached that can drill holes at the ends of existing cracks, in order to stop them propagating.

The Mk 2 can be outfitted with zone 2 compliant components, so that it can be operated in hazardous areas. It is currently capable of operating in most of Asia and the Middle East, in Zone 2 areas.

The Mk 2 is now being designed to have the following modules attached:

  1. Wrapping Module
  2. Painting Module
  3. Coating Module
  4. Clamping Module
  5. Other Modules can be designed by customer demand.
