The Humber Sea Terminal Ro-Ro berth, owned by Simon Carves, is located on the South bank of the Humber. The conditions in the estuary are extreme, with very fast tidal flows, short periods of slack water and zero visibility, which makes working in the water difficult and hazardous.

When the contractor, Edmund Nuttall, was instructed to install a corrosion control coating on the steel piles below low water, they approached Winn & Coales for their recommendation.

In a team effort between Nuttalls, the diving contractor Jones Marine, and Winn & Coales, a SeaShield system incorporating an extremely robust securing mechanism was developed to stand up to the fast and turbulent tidal flow.

To maximize the short working time available at slack water, a hinged cage device was constructed that held the SeaShield jacket in place around the pile. At slack water the cage was lowered down the pile to the desired position, the divers then entered the water and quickly positioned the jacket and secured it firmly around the pile (see Plate 2).

With careful timing and management, optimum use was made of the available time and the installation of the SeaShield system was completed successfully.
