Senesco Marine Shipyard on the U.S. northeast coast has invested in a more productive and efficient welding system, concluding a deal with Pemamek to deliver a PEMA Welding Portal for the welding of double bottoms and subassemblies.   Senesco Marine, a Reinauer Transportation Company, is a shipyard for new construction and vessel repair in the Northeast, consisting of 26 acres of Narragansett Bay waterfront property. To further boost its fabrication capability, Senesco trusted in PEMA’s welding automation technology and made a deal of a twin robot welding gantry. Senesco needed more capacity, so to increase the throughput, the yard got a flexible, yet capable gantry that improves productivity and reduces man hours per vessel.    “The next step for Senesco Marine is to produce not only Quality built vessels but at an increased pace to meet the needs of our customers. We currently are in a continuing build program for our current customers and at the same time are looking at new work for potential new customers. To be able to do this we are making the investment with PEMA to increase the throughput thus reducing the timeframe required to complete these vessels, which leaves room for even more opportunities. We are excited about this step of automation for the Shipyard and are looking forward to the relationship with PEMA as we endeavor to build Quality built vessels on time for our customers,” commented Mr. Michael J
