Geospace Survey Services Limited prouds itself in various partnership for technical support where needed with standard international oil & gas servicing companies, as well as various collaboration with indegenous companies.

GSS carries out engineering investigations of sites and locations worldwide. With access to an expanded fleet, the company offers its clients a fully comprehensive service for offshore, near shore and onshore site investigations.

Our hydrographic survey services provide oil/gas, construction and dredging companies as well as port authorities with accurate bathymetric and seabed data to assist them in the conceptualization and realization of coastal and inshore construction projects. Using high-end bathymetric and associated geophysical systems, our survey teams undertake hydrographic measurements and carry out data processing and mapping. Other hydrographic services include siltation studies, tidal monitoring, monitoring of buoys, current velocity profiling and seabed classification.

To assist our clients to make sound and economical decisions on the design and installation of offshore and subsea facilities, GSS provides detailed surveys of the seabed and below seabed characteristics using specialized staff, survey systems and vessels at various water depths. We undertake pre-engineering surveys to provide information on possible hazards and other impediments to successful engineering projects. For offshore pipeline and cable design and installation, we provide detailed route/corridor information.

In support of offshore projects, GSS provides navigation and millimeter-accuracy positioning solutions on sea surface using satellite technology and below the surface using specialized underwater positioning systems for Offshore drilling rigs, construction barges, pipe-lay operations, jacket installation, submarine cable laying, drill rigs, dredging, seismic (2D seismic and VSP source) and survey vessels. GSS positioning service is based on leading-edge Globally Corrected GPS technology that is stable, accurate and repeatable with real-time integrity monitoring capability. Accurate real-time positioning is equally critical for various onshore based activities in construction and geosciences research.

GSS provides tailored and effective construction support services for offshore construction projects. Services range from control for underwater concrete installations, offshore pipeline and cable installations using specialized survey systems such as GPS/RTK and underwater hydrostatic levelling techniques. Using survey crafts, in conjunction with our affiliates, equipped with comprehensive survey systems including ROVs capable of sub-sea control module maintenance, cutting and grinding operations and pigging, flooding and gauging interaction. Inspection services for marine installations and pipelines to detect possible damage, free-spans, pipe movements etc.
