Commercial Marine Industry Marine Composites Commercial Marine Industry The use of fiberglass construction in the commercial marine industry has flourished over time for a number of different reasons. Initially, long-term durability and favorable fabrication economics were the impetus for using FRP. More recently, improved vessel performance through weight reduction has encouraged its use. Since the early 1960s, a key factor that makes FRP construction attractive is the reduction of labor costs when multiple vessels are fabricated from the same mold. Various sectors of the commercial market will be presented via examples of craft and their fabricators. Activity levels have traditionally been driven by the economic factors that influence the vessel’s use, rather than the overall success of the vessels themselves. Utility Vessels Boats built for utility service are usually modifications of existing recreational or patrol boat hulls. Laminate schedules may be increased or additional equipment added, depending upon the type of service. Local and national law enforcement agencies, including natural resource management organizations, compromise the largest sector of utility boat users. Other mission profiles, including pilotage, fire-fighting and launch service, have proven to be suitable applications of FRP construction. To make production of a given hull form economically attractive, manufacturers will typically offer a number of different topside configurations for each hull. Boston Whaler Using similar construction methods outlined for their recreational craft, Boston Whaler typically adds some thickness to the skins of their commercial boats. Hulls 17 feet and under are of tri-hull configuration, while the boats above 18 feet are a modified deep-V with a deadrise angle of 18 degrees. The majority of boats configured for commercial service are for either the Navy, Coast Guard or Army Corps of Engineers. Their durability and proven record make them in demand among local agencies. LeComte LeComte Holland BV manufactured versatile FRP landing craft using vacuum-assisted injection molding. S-glass, carbon and aramid fibers were used with polyester resin. The entire hull is molded in one piece using male and female molds via the resin transfer molding (RTM) process. LeComte introduced a new type of rigid hull, inflatable rescue boat. The deep-V hull is made by RTM with hybrid fibers, achieving a 25% weight savings over conventional methods. Boat speeds are in excess of 25 knots. [1-9] Textron Marine Systems Textron Marine Systems has long been involved with the development of air cushion and surface effect ships for the government. In 1988, the company implemented an R & D program to design and build a small air cushion vehicle with a minimal payload of 1200 pounds. The result is a line of vessels that range in size from 24 to 52 feet that are fabricated from shaped solid foam block, which is covered with GRP skins. The volume of foam gives 12PDF Image | Marine Componsites
