Don‘t take our word for it, just look at these reports
Pioneer has a wealth of experience that it has gained over the last ten years in designing, manufacturing and selling high performance pumps into industries such as rental, petrochemical, food processing, oil & gas, and of course quarrying and mining.
The company is developing this area of the website in order to publish successes where Pioneer's pumps have made a dramatic impact on the customers operations and as such much has been learnt about how best to operate our equipment.
Case studies and application reports will be published here and when used in conjunction with the Education section, developing solutions to your pump applications should not be such a challenge in the future.
The Norwegian contractor Secora SA completed a challenging project on the island of Værøy, off the coast of Norway, 130 kilometres north of the Arctic Circle. To accommodate larger fishing vessels and ferries, the harbour needed to be deepened. Normally dredgers would have been used for this task, but the basalt granite floor of the harbour at Sørlands meant that the only way is to excavate the additional 3m depth was by drilling and blasting.
Although it is possible to drill and blast under water,the simplest solution in this instance was to seal off the harbour entrance and drain the harbour. However, because of the location, the contractors were racing against time to complete the project before winter set in.
1,200,000m3 in 14 days
A priority was to drain the 1.2 million cubic meters of water in just 14 days.The demand was for high performance pumpsets that could cope with the volumes involved, have proven reliability and were able to meet strict environmental conditions. Because the pumps had to be mounted on barges,the number of pump sets had to be kept to a minimum and be able to run for long periods of time between refuelling.
The original consideration was to use six 12" submersible pumps but Pioneer Pump Limited, working through their Norwegian distributor, IntecPumper, was able to demonstrate that the high performance efficiency of Pioneer's vacuum assisted self priming pumps meant that the work could becompleted with just two 18" pumpsets. Because of the limited work space and refuelling considerations,this was considered the best solution.
On being awarded the contract, Pioneer had just 9 weeks to design, build and deliver the custom 450SM high flow pumpset based on the Pioneer Prime vacuum assisted self-priming pump powered by Caterpillar C9 ACERT Tier III emission compliant diesel engines.They were mounted on skids withan integral fuel tank of 2000 litres, sufficient for 24-hour operation.
The Overall Project
The total project, at a value of 115 million Norwegian krones, involves deepening Røstnesvågenand Sørlandsvågen including the approaches to Sørlandsvågen. There is some 5,000 m3 of loosematerial and 3,000 m3 of rock to be excavatedfrom an area of 7,000 m2 at Røstnesvågen. Worksat Sørlandsvågen involve 170,000 m3 of loos ematerial plus 150,000 m3 of rock in an area of approximately 130,000 m2.
The excavated material, dredged or drill and blasted,is being deposited on land .An area of polluted groundsediments is being moved to a specially constructed landfill site. This is one part of measures being takento prevent contamination of the environment.
Once a box dam had sealed the harbour entrance, the pump barge was deployed.
With a total dynamic head (TDH) of 18 m, and astatic lift of 2.5 meters, the Pioneer pumps maintained a daily output of 3,000 m3 per hour per pumpset operating at an economical 1800 rpm through discharge piping that ran over the harbourwall to the sea.
The Pioneer solution completed the dewatering of the harbour in just 11 days, pumping a total volume of water in excess of 1.4 million cubic meters or 370 million gallons allowing the main contractor to begin excavating 3-days ahead of schedule.
