Dock Water Cooling System Upgrade

The project involved the replacement and upgrade of the dock water system used to provide process cooling across the operational plant.
The existing centrifugal pump and filtration equipment had suffered major failures approximately 18 months earlier and had been replaced by a temporary rented submersible pump and Amiad filter.
The temporary arrangement was not suitable as a permanent seawater installation and presented an ongoing operational reliability risk.
DMD developed the design for a permanent duty/standby system comprising two new submersible pumps and two seawater-rated Amiad filters, connected to the existing heat exchangers.

Dock water is used as a primary cooling medium for the plant, meaning a continuous and reliable supply is essential to maintain production.
The new equipment had to be installed and integrated without interrupting the existing temporary cooling arrangement.
DMD developed a phased design and installation strategy that allowed the majority of enabling works to be completed while the plant remained operational.
Final connection spools and system changeover activities were planned for completion during a controlled shutdown period.

A detailed laser scan and site verification exercise was completed to establish an accurate representation of the existing installation.
Equipment layout and piping route studies were undertaken to determine the most practical arrangement within the available quayside area.
Operational continuity was maintained by developing the replacement system around the existing temporary installation.
Access, maintenance, lifting, installation and future equipment replacement requirements were considered throughout the design.
Enabling and construction packages were developed to maximise the work completed while the plant remained operational.
Final tie-ins and system changeover activities were limited to a controlled shutdown window.
