Dublin Port Firemain Project
Dublin Port operates 24 hours a day, 365 days a year. It employs around 140 people and is Ireland’s busiest port with a cargo throughput of over 29m tonnes annually. In July 2011, Dublin Port Company released a tender for the upgrade of the fire pumping equipment throughout the oil storage area of the Port. The project would require the installation of a new fire main with pumps capable of delivering sufficiently high volumes of seawater to tackle the unfortunate event of a port fire.
Drilling and Pumping Supplies LTD submitted a technical proposal to the Dublin Port Company in July 2011 with further work throughout the rest of the year resulting in successfully winning the order in July 2012.
The pumps selected were from the Robust ClydeUnion vertical turbine range, chosen especially for their high performance and maintenance efficiency. This particular selection would ensure that the operating costs over the lifetime of the unit would be kept to a minimum. The pumps are manufactured in corrosion-proof, Nickel-Aluminium Bronze, ideal in cold seawater conditions, and fitted with 375 kW, IE2, WIMES motors.
The units were each required to produce 152 l/s at 166.7 meters or 16.2bar head.
Combined, the 5 pumps are capable of generating sufficient head to deliver 36,500 litres/minute of water for fire fighting with a minimum pressure of 10 bar at the point of connection. The flow from these pumps is supplemented by an existing Jetty Pump House to achieve a total flow of 50,000 litres/minute of water with 10 bar pressure at the point of connection.
The system is supported by a KSB borehole unit acting as a “Jockey pump” to maintain the supply at a minimum operating pressure during periods of low flow.
The pump units were ordered and a factory acceptance test was completed in May of 2013 and attended by DPS and DPC.
Delivery of the 5 pumps was made to the Port in August 2013 before DPS where tasked with the installation contract within a three week window before the Electrical contractor arrived on site. Installation commenced mid September and was successfully completed in early October 2013.
With commissioning starting in January 2014 and expected to run into February 2014, the DPS team assisted Jacobs engineering alongside the electrical contractor on site to establish a workable and detailed control philosophy for the project.
This will close out a rewarding contract for both DPC and DPS and we look forward to working together in future.
