Enquiry

The customer’s vessel periodically goes into dry dock in locations where there is intermittent power supply. As a result the dock(s) couldn’t provide a guaranteed and reliable supply of AC, refrigeration and fire water systems from the dock yard. This meant that the customer had to house their 900 crew members in local hotel facilities and transport them to and from the dock yard each day during the docking period which could be as much as a couple of months. The costs related to this are astronomical.

Solution

To design, build, test & supply a portable, self priming, variable speed fire water supply pump package which can be powered by the client’s vessel (60A max supply) whilst it is in a remote dry dock.

These systems enabled the client’s vessel to be completely autonomous in the supply of fire water, AC and refrigeration services whilst it was in dry dock, enabling the crew to remain on board during the docking. This saved the client tens of thousands of pounds in hotel, logistical and down time costs, meaning that within 1 dry dock the system had paid for itself.

In addition to the pump packages Castle Pumps Ltd. also supplied over 900 m of 1½”, 4” & 6” Suction & Discharge Hose Assemblies to connect the packages to the ships on board systems. All the equipment was subsequently stored and transported in an on board container which could then be unpacked and re-used at the next dry docking.
