Portsmouth Cable Relocation | Ground Investigation

Magma Global Limited commissioned us to undertake a ground investigation to assess conditions along the proposed route of a large subsea cable within its Portsmouth facility.   

The cable was required to be transported for the production facility, through an existing boat stack warehouse, before being loaded onto a barge for deployment. 

Given the size and weight of the cable and associated transport equipment, a clear understanding of the ground conditions was essential to support the safe planning and execution of the operation. The investigation was designed to identify any ground- related constraints that could affect the movement of specialist vehicles, temporary works, or loaded activities.  

Working within a live industrial environment, our team delivered a targeted ground investigation programme that minimised disruption to ongoing operations. The scope of works included window sampling, dynamic probing, and dynamic cone penetration testing (DCPT) to establish the nature, strength and consistency of the underlying soils along the proposed transport route. 

This investigation provided Magma Global with the confidence to progress with the relocation operation, helping to reduce risk, inform logistics planning, and ensure the safe transportation of a critical subsea asset.  

By delivering a focused and cost-effective investigation, we supplied the project team with the information required to support a successful and efficient operation.
