Geotechnical - Is a specialty of civil engineering which deals with the properties, behavior and use of earth material (soil & rock) in engineering works.

Sub Surface Exploration - The objective of any subsurface exploration program is to determine the nature and sequence of the subsurface strata (geological regime), groundwater conditions (hydro geological regime) and physical and mechanical properties of the sub surface strata. The exploration report provides the owner/developer/engineer with an evaluation of the suitability of the site for the proposed project as well as design recommendations to accommodate the subsurface static and dynamic soil conditions, bearing capacities etc. A typical report would provide recommendations on foundation system alternatives, specific foundation design parameters and possible mitigating methods for soil improvement for the type of application and structure. Geotechnical explorations typically consist of test borings to obtain geologic information and samples of the site soils / rock, in-situ and laboratory tests to determine the relevant engineering properties of the various soil/rock strata, providing recommendations on foundations and where required with specific analysis of leg penetration, pull out loads, pile driveability analysis etc. The number and depth of borings, drilling and sampling techniques, type of in-situ tests and methods of laboratory analysis are highly dependent on various project details, including the type of facility and proposed structural system, as well as site specific factors, such as topography, geologic setting, and previous development activity.

COMACOE and its engineering staff have conducted a number of geotechnical explorations throughout the West Coast and East Coast of India as well as various locations ranging from east and west coast of India, Caspian Sea - Kazaksthan, Gulf of Mexico, South China Sea - Vietnam & Malaysia for both marine and land infrastructure development projects. These include ports & harbors, offshore feed-stock handling facilities (LNG Terminals/SBM’s, SPM’s), Leg Penetration Analysis for Jack Up rigs, bridges, jackets, pipelines, onshore tankages, power plant etc.

Logos Searcher is a dedicated geotechnical vessel operated by COMACOE. The 4 point mooring vessel is permanently mobilized with a heave compensated drilling rig complete with downhole CPT, wireline sampling tools, seabed frame and mud pump. The vessel has completed over 1500m of offshore investigations related to platform and leg penetration analysis (LPA) for a variety of clients in the oil and gas segment in India and overseas.

Over the years Coastal has formed association with some leading engineering organizations to augment its in-house resources:
