Geotechnical Consultancy

OSL has in-house capabilities supported by alliance partners to provide marine/ coastal geotechnical engineering and operational expertise to potential Clients. This expertise extends from project design and planning to technical supervision, data processing and reporting for geotechnical engineering purposes. Reporting deliverables include Standard Static Data Reports for platform and pipeline investigations, Jack-up Leg Penetration Analyses, Pile Design Information, etc. OSL also provides CPT data processing for down-hole or seabed systems using CPeT-IT software.

OSL also provides operational support for vessel mobilizations, equipment selection and set-up and field operations for site investigations for platforms and jack-ups using rotary or top-drive drilling systems, pipeline or cable surveys using jumbo-piston, gravity or vibro corers or seabed CPT systems and coastal geotechnical investigations from barges, pontoons or shallow water vessels.

Data Processing and Reporting

OSL is able to perform, either in-house or through our dedicated geo consulting alliance, a variety of data processing and reporting tasks to meet project specifications. Whether it is Multibeam data processing using EIVA Naviedit, Navimodel3, Naviplot and Imaging packages, chart production for route alignment or bathymetry or seabed features, isopach maps and full drilling hazard reports. These can be performed on board, remotely (on shore) or post-survey.

MMO/PSO & PAM

OSL provides Marine Mammal Observers, Protected Species Observers and Passive Acoustic Monitoring Operators to support environmental regulatory requirements for offshore operations.
