Geophysical and geotechnical survey

We perform marine surveys for clients in the oil & gas, renewable energy, and power transmission markets, with a complete package of geophysical, environmental, and geotechnical investigations.

Our survey team is supported by a strong laboratory and experienced geotechnical engineers, ensuring that results are sound and fit for final design.  

We offer a full range of site surveys for project development, both offshore and onshore, and we are experienced in challenging shallow water, ‘nearshore’ projects. We provide the basic data for design of all man-made structures and carry forward special issues such as geotechnical engineering and monitoring. 

Services

Investigations for marine constructions include: 

- Piled jackets 
- Gravity base structures 
- Floating facilities and FPSO 
- Anchors and suction piles 
- Offshore pipelines 
- Jetties and ports 
- Jack-up rig siting 

Geotechnical investigations from dedicated drilling vessels or jack-up platforms include: 

- Soil and rock drilling 
- Sampling (undisturbed and disturbed) 
- In-situ testing (CPTU, T-bar, seismic cone, vane shear). 

Main types of support for geophysical surveys are: 

- Preparation of technical specifications for the survey (e.g. survey plan, vessel and equipment requirements), survey data processing/reporting and estimation of costs and duration  
- Provision of on-board personnel (e.g. for QA/QC data, preliminary data interpretation for survey optimization, and as client representative) 
- Bid evaluation support. 

We are specialized in geophysical data interpretation for geological modelling and geo-hazard identification. Our expertise includes: 

- Morphological interpretation, based on an open-source database, digital terrain models (e.g. elaboration of survey bathymetry data, topographic survey) and side scan sonar imagery 
- Geophysical interpretation for seismo-stratigraphy and structural mapping, based on sub-bottom profiler, ultra-high resolution and 3D seismic data 
- Geo-hazard and geological mapping 
- Integration of geophysical and geotechnical survey data on the GIS platform. 

Why RINA?

We have been active in geotechnical and geophysical offshore surveys for decades, with a significant track record in shallow to deep water projects, mainly for oil & gas projects. 

We use our dedicated containerized field laboratories for testing on board of vessels or in remote field locations. Standard and advanced testing, as well as sedimentology core logging, are carried out in our laboratory in Genoa, Italy. 

RINA is certified ISO 9001:2015, ISO 14001:2015 and BS OHSAS 18001:2007.
