Rapallo completed design work to improve and extend the life of the sea wall and sea water pumping facility. Rapallo’s scope included:
• The design and methodology for the replacement of the sheet pile wall, tie rods and anchor blocks;
• Redesign of the pipework to improve overall pump flow rates; and
• Redesign of the roadway over the pipes to ensure correct load bearing capacity.
Rapallo Engineers considered the construction process as well as plant production requirement in the design process by ensuring that two pumps could remain in operation while the third pump was shutdown to allow the upgrade to take place. Additional design features included the allowance for the installation of the new sheet pile wall without requiring the removal of the existing wall, the design of larger diameter pipes to increase production flow rates and modification of existing pump diffusers to allow for the larger diameter pipes.
