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
