Enviros was contracted by Nador WestMed to perform a geotechnical site investigation offshore Morocco; for a proposed port and harbour development site where water depths ranged from 15m to 40m. The geotechnical site investigation scope of work comprised over forty composite (undisturbed sampling and in situ testing) and dedicated in situ testing boreholes for the purpose of piled structures (quay / jetty) and breakwater design. Boreholes were advanced using a heave compensated API rotary flush drill string with wireline coring capability to suit ground conditions and the acquisition of high quality geotechnical data.
Recovered undisturbed samples and rock cores were logged, extruded, photographed and described in the offshore soil / rock laboratory. Selected undisturbed samples were retained in Shelby tubes to be available for onshore advanced specialist laboratory testing. Enviros performed ‘real-time’ testing of recovered samples and data processing of in situ tests to optimise the operational program and final borehole depths based on the Client’s design requirements.
A ‘Final Engineering and Soil Parameters’ report presenting engineering design parameters appropriate to proposed structures, slope stability analyses and an assessment of soil liquefaction was issued on completion of all scheduled onshore laboratory testing.
Project Organisation
Enviros was responsible for performance of all pre-mobilisation, mobilisation, fieldwork, demobilisation and associated onshore laboratory testing and reporting. A senior Enviros Project Manager with >15 years relevant offshore site survey / investigation experience was appointed on contract award and responsible for each project phase and Client liaisons throughout. The Enviros Project Manager appointed an experienced Enviros Offshore Project Manager for all fieldwork operations.
The Project Manager had the role of managing day-to-day issues relating to the project, based onshore in the Enviros head office based in United Kingdom. The Offshore Project Manager was responsible to ensuring that the project was completed in accordance with Enviros procedures and to Client specifications. Responsibilities include, but not limited to being the immediate point of contact for any Offshore Client Representatives, ensuring project QHSSE procedures are adhered to during all offshore operations; this is to include mobilisation, field calibrations and checks, project tasks, post project calibration checks and demobilisation; and the production or approval of all necessary field reporting.
