Location: Lyttelton, Christchurch
Client/Owner: New Zealand Oil Services / Shell Oil Services
Contractor: City Care Ltd
Duration: Two years

Shell Oil Services decided to upgrade petroleum storage tanks at their Lyttelton Site that will result in the development of three new storage tanks. Geotechnics won the contract to install geotechnical instrumentation below the tanks foundations.

The project was run out of the Geotechnics Wellington office with supervision from the Geotechnics Tauranga office. In total, ten vibration wire (VW) piezometers and six profilometer pipes will have been installed by the end of the project. Two tank foundations have been completed. Each tank site contains one deep (19m) and one shallow (5m) VW Piezometer. Two Profilometer pipes were laid perpendicular to each other at the surface of the foundation. The combination of the data from both the VW Piezometers and Profilometers will allow the authorities to accurately monitor tank settlement during the construction and hydro testing phases.
