Owned, in-house survey and Geotechnical vessels with dynamic positioning, multipoint mooring etc capabilities coupled with in-house state-of-art laboratories and experienced personnel, enable consistent and high quality, dependable reports for COMACOE’s clients.

Till December 2016, COMACOE has completed over 200 survey and geotechnical projects, in water depths ranging from 0 to 500 meters, covering approx. 100,000 sq. kms and has drilled over 45,000 mtrs in different soil strata.

COMACOE owns and operates fully equipped survey vessels equipped with a wide range of survey equipment to meet a wide variety of applications and objectives. In addition, a full suite of systems for mobilizing on client-provided or owned vessels, barges or crafts of opportunity are always readily available at all our operating bases.  Highly capable and experienced personnel resources encompass all streams and consist of Hydrographic Surveyors, Land Surveyors, Geophysicists, Geologists, System Engineers, Data Processors, GIS CAD Operators and Analysts etc. An in-house training center ensures that all our personnel are continuously upgraded and kept updated with new technology developments and techniques. In-house training also enables continuous skill development and career progression of our employees.

With a history of over 25 years of doing marine surveys and being a pioneer in the field in India, COMACOE has the unique advantage of having conducted surveys and geotechnical operations all over India’s vast coast line and with most critical team members continue to be in the company since inception, the collective knowledge base and practical experience of operating in the marine environment across India’s coastline is extremely valuable and enables us to bid and successfully execute highly complex projects consistently in challenging environments such as Gulf of Cambay in record timelines with confidence. Needless to mention, this history of over 25 years of existence has led to high visibility and mutual respect within the marine community India-wide and this solid reputation painstakingly built over years of successful execution of 100s of projects goes a long way in ensuring success of our ongoing and future projects.

Offshore Geotechnical investigations

COMACOE acquires geotechnical and other data to characterise the subsurface. Data is collected using a variety of methods, tools and sensors ranging from drilling and sampling, wireline and/or seabed cone penetration testing (CPT),  geophysical methods to conventional drilling techniques across various water depths and geological formations and for the entire range of offshore structures requiring deep and shallow foundations.

Our combined Geotechnical capabilities make us the largest supplier of marine geotechnical services in India with global experience of successful projects in Kazakhstan, Qatar, Iran, Iraq, UAE, Sudan, Vietnam, Malaysia, Brunei, Bangladesh, Mexico, Mozambique, Tanzania and Nigeria. We have successful completed campaigns in some of the most challenging marine environments in the world. Our fleet of dedicated drill ships enables us to provide tailored investigations in all the offshore regions of the world, from the shallow near shore environment to the deep waters.

Our field data acquisition capabilities are complemented by our other geotechnical services which include desk top studies, advanced laboratory testing, numerical and physical modelling of foundations and consultancy and engineering analyses. When these are combined with our specialists within COMACOE who operate in the fields of geology, geophysics and other related geosciences, COMACOE can deliver the total package from conceptual design, through installation, operation and field abandonment.

Our in-depth experience, technological capability and with suitable spread mean we can provide optimum solutions for the design, installation and operation of offshore facilities, anywhere in the world.
