Abstract

An arrangement for use in the protection of pipes and trunks (10) in a splash zone on a rig construction or similar installation at sea using a cylindrical container (12) closed below and open above and arranged along the pipe or the trunk. The container (12) which is of two-part construction has a longitudinal dimension which spans over normally submerged and normally exposed pipe and trunk portions. The container (12) is employed for cleaning, inspection and application of corrosion protective medium on the pipe and trunk surfaces bounded by the container (12). There is defined between the container (12) and the pipe or trunk an annular chamber of limited breadth. In the chamber, a carriage unit (30, 43) is moveable in the axial direction and peripheral direction of the chamber and supports equipment for cleaning, inspection and application of corrosion-protective medium. A method of using this arrangement involves assembling the two parts of the container around the pipe or trunk, draining the annular chamer and actuating the carriage unit to effect movement thereof around the pipe or trunk as well as axially of the latter while simultaneously actuating the supported equipment.
