Five Trinity Industries Subsidiaries Team To Build LPG Barges In what may be a record in ship- building teamwork, five subsidiar- ies of Trinity Industries, Inc., are cooperating in the construction of two 260-foot liquid propane gas (LPG) barges for Harvey Gulf, Inc., Harvey, La. The barges will be constructed, erected, and painted at Gretna Ma- chine and Iron Works, Inc., Harvey, with components manufactured on site along with elements from the following Trinity companies: Equi- table Shipyards, New Orleans, La., sandblasting and preconstruction primer; Equitable Shipyards, Madisonville, La., automated panel line fabrication; Trinity-Beaumont, Beaumont, Texas, tank placement assistance; and Beaird Industries, Shreveport, La., manufactured LPG tanks. Each barge will be fitted with two 213-foot-long independent Beaird LPG tanks with inside diameters of 16 feet 9 inches, and a working pres- sure of 266 psig (pounds per square inch gauge). Each barge can carry 15,000 barrels of LPG. The tanks will be shipped by rail from Shreve- port to Beaumont because they are too large to negotiate some tight turns in the Louisiana railway sys- tem. John Dane III, president of the Trinity Marine Group which in- cludes 10 shipyards (Beaird is part of another Trinity segment), said the team effort is a good example of Trinity's efforts to hold down com- pany and customer costs by reduc- ing redundancy or duplication within its plants. Both barges are expected to be delivered in the third quarter of1992.

The Mississinewa and four other Neosho Class Oilers are being placed in the Reserve Fleet as Avondale Shipyards continues the scheduled construction of 18 Kaiser Class Oilers. Dehumidification is essential aboard the vessels of the Ready Re- serve Fleet because maintaining relative humidity at or below 35 percent will inhibit moisture-in- duced corrosion. Dehumidification systems designed by L&C Associ- ates utilize disiccant dehumidifiers and a spray applied moisture bar- rier to maintain the integrity of the dehumidified spaces. This combi- nation of dehumidification and seal- ing will maintain the ship's present condition for the duration of the layup. L&C's dehumidification system circulates dehumidified air to both the forward and aft deckhouses, machine space, pump rooms, cargo control areas, storerooms, ship ser- vice areas, and all refrigerated stor- age space. After completing the installation of the dehumidification system, L&C technicians created a vapor barrier to prevent moisture from entering the dehumidified spaces through vents, skylights or hatches. All open- ings leading to the dehumidified spaces were sealed with PSS, a spray applied vinyl plastic. PSS is as ef- fective as sheet metal blanks in keep- ing moist air from entering the de- humidified space. But since PSS can be installed more quickly and removed without any special tools, There's a PSS greatly minimizes the cost of installation and subsequent reacti- vation. L&C Associates is the leading provider of dehumidification and sealing systems to marine clients and has provided dehumidification systems for more than 120 clients for both military and commercial applications.
