Geo’s geotechnical engineering expertise in the offshore industry covers a wide range of services. Our focus is to provide safety and cost-effective solutions for our clients.
Some of our services that offer a leading expertise include:
Engineering assessment and design of foundations (spudcans, skirted foundations and mudmats) for jack-up oilrigs, jack-up wind energy vessels, and offshore jacket and substation platforms.
Jack-up leg penetration analysis using Geo’s in-house programs, Plaxis 2D and 3D, ABAQUS, ELFEN FE codes, etc.
Interaction of the spudcans and skirted foundations with other seabed structures or seabed features like: Jacket piles, footprints, pipelines, quay walls and sloped seabed.
Calculations for preload and storm loads (V-H) and (V-H-M), consolidation analysis, pseudo-dynamic calculations and other analyses for jack-up rig foundations.
Design of gravel banks, gravel beds, gravel pads, excavated beds, and seabed perforation (Swiss cheesing) for safe installation and operation of different oil jack-up platforms and jack-up vessels (applicable to wind energy).
Static and dynamic analyses of gravity based and skirted mudmat foundations for oil platforms, windmills and substations, using PLAXIS, ABAQUS and other programs.
Pile driving analyses and pile bearing capacities applying GRWEAP-2010 and pile ultimate axial and lateral load capacities analyses applying DNV guidelines and APILE, LPILE2010 etc. for different offshore structures.
Geotechnical interpretation of soil data from site surveys and geophysical investigations applicable to offshore projects, in correlation with geotechnical investigations, borehole / CPTs, and laboratory static and dynamic test results.
Complete project management and offshore site supervision.

One of Geo’s primary tasks is to share its knowledge and experience in order to provide a greater understanding of the geotechnical challenges, which must be taken into account in offshore structures and foundations.
Geo has conducted several domestic and international courses on offshore geotechnical engineering, design of offshore foundations, conventional and numerical modelling etc.
Geo is an active actor and contributor in research and development studies in different fields of geotechnical engineering, geomechanical, dynamic, soil-structure interaction etc. Geo has participated as special sponsor in different Joint Industry Projects (JIP) and many of Geo’s senior staff have an extensive experience in lecturing, special committee membership such as Plaxis Development Committee (PDC) etc.
Some of the research and studies topics are presented below:
Investigating and developing new procedures for the improvement of the predictions of spudcan foundations during installation and removal of Jack-Up units (development of Geo’s in-house softwares)
Design of cost-effective foundations for wind farm
Seabed Instability and 3D FE Jack-up Soil-Structure Interaction Analysis
Skirted Footings Capacity for Combined Loads and Layered Soil Conditions etc.
