Overview

Prior to works commencing, an application was made to the Royal Docks Management Authority (RoDMA) for all diving works, and for the relevant permits, to enable us to safely remove the steel tubular piles from the docks.

To ensure smooth and safe operations were undertaken on site, the full scope of works was carefully planned, method statements and risk assessments compiled and submitted, and then fully briefed and discussed with a highly skilled dive team, prior to mobilisation.

The DiveCo team were required to cut the required piles into sections and lift them on to the dock edge with a floating crane barge for disposal.

Silt was removed from the base of the piles using high pressure water blasting and air lance equipment, to enable access for the divers to cut the piles to a given level. Lifting points were established and cut into the existing piles for secure connection to the lifting equipment.

The divers utilised a specially designed, hydraulically operated diamond saw, but were challenged not only by poor visibility in the water, but also by the composition of the concrete core and pockets of gravel.
