Subsea Pipelines- Fluid & Gas

The Lifeline of Coastal and Offshore/Onshore Infrastructure

Intake, Outfalls, Pipelines – for fluid & gas distribution & conveyance!

Intake & Outfall Systems are not just components of marine infrastructure; they are the lifeblood of essential domestic and industrial processes, driving power generation, refineries, industries, captive and municipal desalination, water supply, effluent and wastewater management. At COMACOE, we have mastered the intricate art and science of designing, constructing and maintaining these vital systems, ensuring they operate with unmatched efficiency and reliability.

A Leader in Intake, Effluent & Subsea Pipeline Solutions

Recognized as a market leader in India, COMACOE has successfully delivered over 90% of the country’s large-diameter marine intake & outfall projects in the past decade. Our expertise transcends mere construction; we provide comprehensive end-to-end solutions that encompass everything from site surveys and deep-sea excavation to the installation of high-capacity pipelines and advanced maintenance practices.

We pride ourselves on being agnostic to both the material of construction (GRP, HDPE, DI, MS, CS, SS, DSS, Composite Materials) and the types of contents our pipeline systems convey. From seawater, freshwater, effluent, greywater for industrial & municipal requirements or oil, petroleum product or gas for exploration & refineries, we design and build meeting the required standards and specifications for safe and efficient transportation bespoke to each requirement.

Our approach to pipeline projects is anchored in precision engineering and environmental stewardship. We are acutely aware of the challenges posed by marine environments, which is why we have pioneered specialized techniques to suit the conditions including Microtunneling (MT) and Horizontal Direction Drilling (HDD) with subsea recovery. These innovations empower us to overcome hurdles, ensuring that every system we deliver stands resilient against the forces of nature and operates harmoniously within its ecosystem.

Our portfolio of marine intake and outfall projects showcases our commitment to engineering excellence and innovation. We have successfully executed a wide range of solutions, each tailored to meet the unique demands of our clients and the environments we operate in.

Our Projects Encompass:

Subsea Pipelines :
- Carbon Steel concrete coated oil & gas (below 40m water depth)
- HDPE, GRP, MS – large diameter
Large-Diameter Intake Well Caissons: Robust and meticulously engineered to ensure efficient water flow while withstanding the challenges posed by marine conditions.
Innovative Velocity Cap Structures: Designed to optimize water intake while minimizing environmental impact, these structures exemplify our forward-thinking approach to marine engineering.
Multiport Diffusers: Engineered to enhance dispersal efficiency and mitigate environmental effects, our diffusers ensure a seamless integration of inflow and outflow systems.
Desilting Basins: Essential for maintaining water quality, our basins are designed to effectively manage sedimentation and facilitate smooth water flow to pump houses.
Pump Houses / Forebay: Built to ensure reliable operation and efficient management of water resources, our pump houses are the backbone of our intake and outfall systems with complete EPC solution of electrical/ sub-station, mechanical, SCADA/ PLC, DCS, Instrumentation, IT, equipment handling units, firefighting systems, chlorination system, ABS system etc.
Gates and Screens: Precision-engineered to control flow and prevent debris from entering the system, ensuring optimal performance at all times.
Filtering Systems: Our advanced filtering technologies guarantee the highest standards of water purity, catering to the diverse needs of our clients.
Low Temperature Thermal Desalination (LTTD): As a pioneering solution to combat water scarcity, COMACOE's LTTD systems leverage innovative technology to transform seawater into fresh water efficiently. By utilizing low-grade thermal energy and harnessing natural temperature differentials, our systems draw cold water from deep ocean depths of approximately 600 meters and mix it with warm surface water in a flash chamber, promoting effective condensation. This method not only minimizes energy consumption and environmental impact but also ensures a sustainable approach to addressing water scarcity. We take pride in successfully designing, building, and operating three LTTD plants in the picturesque Lakshadweep Islands, India.
Ocean Thermal Energy Conversion (OTEC) leverages the temperature difference between warm and cold seawater to generate energy while integrating LTTD to produce freshwater, making it a sustainable solution for both energy and water needs
Inbuilt Pipeline cleaning and maintenance system: Successfully designed and installed pipeline cleaning systems like Air Bursting, Air bubble curtain, hypochloride dosing & Pigging systems with innovative design to facilitate line maintenance of intake structures/pipelines and extend the periodic maintenance cycle.
Air evacuation & degassing systems: Air ingress or release of dissolved gases is a common phenomenon which have a detrimental effect on the hydraulics as well as stability on marine intake & outfall pipelines. We have successfully designed and installed suitable bespoke systems for such mitigation.

Through these innovative designs and solutions, COMACOE not only enhances operational efficiency but also prioritizes environmental sustainability, ensuring that our projects harmonize with the ecosystems they inhabit.
