Horizon Geosciences

Geophysics

Horizon performs geophysical surveys to gather the detailed data required by design engineers and installers of offshore structures, subsea cables and pipelines. That data is used to:

• Map seabed morphology and sub-seabed conditions
• Profile geological features
• Detect geohazards
• Provide a seabed and sub-seabed reference for geotechnical investigations

We operate a fleet of owned and chartered vessels which are mobilised for geophysical surveys in the deep ocean, the continental shelf and the shallower nearshore areas.

Geophysical surveys are typically required for:

• Site surveys for rigs or platforms
• Windfarm developments
• Route surveys for pipelines or cables
• Geohazard and fault detection
• High resolution seismic mapping
• Geochemistry

Horizon also has a full range of geophysical survey equipment including:

• Multi-beam and single-beam echo sounders
• Analogue sub-bottom profilers (Pinger / Boomer / Sparker / CHIRP)
• Digital sub-bottom profilers (/ 2DHR / UHR)
• Digital side scan sonars
• Magnetometer and gradiometers

Our geophysical survey vessels can also be equipped with:

• Remotely Operated Vehicles (ROVs)
• Environmental sampling equipment

The vessels feature on-board processing and reporting facilities which allows for seamless integration of the data sets which are processed, interpreted, reported and charted offshore.

Horizon’s deliverables are tailored to meet a  client’s specific requirements, and typically include hard and soft copies of:

• Factual / interpretive and combined reports
• AutoCAD / PDF charts
• GIS deliverables to OGP/IMCA Seabed Survey Data Model (SSDM) or client specified geo-database schematic formats
