Seawater Uptake Systems

EMSTEC Seawater Uptake Systems (SUS) provide a means of obtaining low temperature as well as low oxygenated seawater to benefit the vessels process and utility systems. Also known as the Cooling Water Intake System it is always custom designed to fit the various vessel types.

Through Intake Riser Connections such as pipes and hoses, the required cooling water can be reached in depths from 30m up to 300m (Deep Water Riser).

EMSTEC Seawater Uptake Systems are fully engineered to suit individual applications and installations worldwide. Use of our EMSTEC in-house hydrodynamic analysis software ensures that all vessel motions and environmental conditions specific to the installation are considered and accommodated within the system design. The selection of materials and surface protection ensure efficient and low maintenance during operation.

The EMSTEC system is supplied as an integrated package and includes all handling equipment to ensure safe and efficient installation. EMSTEC provides comprehensive and fully integrated systems to meet clients specific requirements as well as supervision services to guarantee a reliable and safe handling.
