Dave contacted me on a Wednesday morning. He was the purchasing manager at a marine services/underwater engineering company. They were awarded the contract for a de-silting operation in a large river in the northeast. They needed to pump silt in to a barge, and then from that barge to a hopper barge, filter the sediment, and then back into the ocean. The water was to sit in the hopper barge over night and then be skimmed to another barge, and finally needed to be filtered of all particulate larger than 200 micron before being pumped back into the ocean at a rate of 1000 GPM. As such, Dave expressed his interest in renting a filtration vessel that could be utilized on the boat.
I reviewed our list of rental vessels to see if we had a bag filter housing which would handle 1000 GPM. Luckily I found a horizontal bag filter housing which utilized 7-round 80″ long bag filters. I then checked our supplier’s inventory and, once again, luckily we had 60 of them ready to ship. I conveyed all this information to Dave and he quickly placed the order. After we had already begun the process of getting the filter vessel and bag filters shipped to Dave’s location, he contacted me last minute and said that he needed to change the filtration efficiency to 100 micron retention instead of 200 micron. I immediately contacted our supplier and requested a change, to which they responded accordingly after finding some old inventory of 100 micron bags that would fit the same filter vessel. In the end, because of the lower-micron filters and the last minute change, Dave had to pay a little bit extra and wait some more to receive the products, but our inside sales team made sure that they entire process ran correctly and smoothly, and Dave’s company successfully received the filter bag housing that they were expecting, with the 100-micron bag filters that they needed.
Upon starting up the vessel, Dave discovered that they were going to need more bag filters than they originally anticipated, so he contacted me once again to quickly place an order for more. I made sure to work with our shipping department to expedite the order and the partial shipments in order to keep their de-silting project in operation. I wanted to help them avoid a shut-down and thus have them risk not completing the job in the time-frame that they specified to their customer, which would’ve been bad news. In the end, Dave’s barge filtration operation required the entire time that was allotted to them, but it was completed on time. Success once again!
