Geophysical Surveys

Our survey operations are underpinned by the Applanix POS MV Wavemaster — a fully integrated GNSS and INS system for real-time vessel position and orientation. It is standard across our fleet and essential to most geophysical services.

All three Green Marine survey vessels are equipped with one or two dedicated deployment poles, allowing for flexible mounting of MBES, SBP and USBL systems.

Deployment

  • Deployment options include moonpools and overside poles, depending on equipment and site conditions.

Adaptor Brackets

We maintain a range of custom adapter brackets from previous operations, enabling rapid integration of various MBES and SBP units.

ROV-Based MBES

Our ROVs are now equipped with the Sprint Nav-Mini — a survey-grade DVL/INS solution that enables high-resolution MBES data capture at low altitude. This system is ideal for detailed cable and pipeline tracking, and clients have praised its precision and reliability.

Valor ROV Compatibility

Our Valor ROVs come pre-configured with both primary and redundant cable sets, fully compatible with Norbit iWBMS and Winghead MBES systems for quick mobilisation.
