Survey
Full suite of geophysical, seismic, environmental and geotechnical survey services
Smart survey solutions for subsea infrastructure planning
We provide the essential subsea site characterisation information our customers need to support subsea infrastructure planning and de-risk project decisions. We deliver the information concisely, transparently and on time.
N-Sea acquires survey data that is essential for offshore energy developers, operators and subsea installation & construction companies to optimise the design and productivity of their subsea infrastructure, whether for new developments, lifetime extensions or decommissioning. We understand that in many instances frequent inspection and monitoring prevent ad hoc maintenance and expands the lifetime of subsea assets.
