SeaDrain Plus Piping System is avail- able in sizes from 1.5-6 inches with a wide range of Drain, Waste and VENT (DWV) approved Þ ttings. Primary ap- plications for this unique piping include gray and black water systems and sew- age transfer; encompassing all hot and cold running water systems throughout the vessel. Like GRE Ð used for other applications Ð a 40-70 percent weight savings can be achieved by replacing traditional metal piping with SeaCor. Other advantages include the in- creased efÞ ciency due to a lower coef- Þ cient of friction in plastic pipe than in metallic pipe. This allows the pos- sibility to achieve desired ß ow rate us- ing a smaller diameter pipe, resulting in less initial cost for pipe, valves, Þ tting and pumps, while still maintaining the same or lower friction losses. In terms of material costs, SeaCor is competitive with copper and stainless steel systems. Steel and galvanized pipe have a lower initial material cost, but the advantage is lost on installation and welding time. BOATBUILDING ÕS POTENTIALLY POWERFUL TRIPLE PLAY Imagine the possibilities: Your next workboat incorporates the latest in propulsion technology, redundant DP equipment and yes, the weight savings and lifecycle reduction in costs associat- ed with GRE piping, SIMS composite pumps (that run smoother and require far energy) and impellers and SeaCor (smaller diameter) plastic piping. Your boat now carries more payload, stocks less in the way of equipment spares, corrosion issues have been halved and your bottom line beneÞ ts signiÞ cantly from lower acquisition and installa- tion costs. WhatÕs not to like? These arenÕt mere possibilities for the future. They are here now. Owners and opera- tors looking to have the most efÞ cient workboat possible and the advantage of running green can have both. In the end, some parts of that equation might cost less than you might think. www.marinelink.com MN 51MN May2013 Layout 50-59.indd 51MN May2013 Layout 50-59.indd 515/3/2013 1:00:31 PM5/3/2013 1:00:31 PM
