Offshore stone columns — installation and ground treatment overview

HOW IT WORKS

Installation sequence

01

Plan marine operations

Review marine access, working arrangements and environmental requirements.

02

Position & install

Control positioning and installation using the project-specific marine method.

03

Record & verify

Maintain position and treatment records and undertake the specified tests.

APPLICATION & ENGINEERING

Ground improvement beneath marine works

Column positions and treatment depths are controlled against the surveyed seabed and approved grid, with marine access and environmental controls integrated into execution.

When to choose this method

Offshore stone columns improve suitable seabed soils beneath marine developments. Marine positioning, seabed levels, water depth and operating conditions must be coordinated with the treatment grid and installation equipment.

Planning the installation

The ground investigation, groundwater conditions and structural requirements inform method selection. Working access, installation sequence and effects on neighbouring structures are reviewed before execution.

Construction control points

  • Review marine access, working arrangements and environmental requirements.
  • Control positioning and installation using the project-specific marine method.
  • Maintain position and treatment records and undertake the specified tests.

Verify marine coordinates, penetration and aggregate quantities at each location. Use the approved marine survey and ground-verification programme to assess installation and performance.

FROM SITE DATA TO A TECHNICAL PROPOSAL

Define the ground. Plan the solution.

Share the site location, geotechnical report, structural loads or excavation requirements, drawings and target programme. These inputs allow the engineering team to assess method suitability, equipment access, installation sequence and the required verification plan.
