L&C Associates Installs Dehumidification System Aboard S.S. Beaver State L&C Associates, North Hampton, N.H., recently announced the com- pletion of a dehumidification, seal- ing and alarm system aboard the S.S. Beaver State. At the direction of MarAd, the T-ACS-10 vessel is being dehumidified to protect it from moisture-induced corrosion. Most notable to the installation is the use of Protective Sealing Sys- tem, PSS to seal openings leading to the dehumidified spaces. Protective Sealing System, PSS is a spray- applied, semi-adhering, flexible, vi- nyl plastic which prevents moisture from migrating into dehumidified spaces. Since PSS is strippable, the vessel can be reactivated quickly, a key requirement of the lay-up speci- fication. L&C technicians designed and in- stalled the desiccant dehumidifica- tion equipment, and the ducting system which distributes the dehu- midified air. Other components of the L&C package included an alarm system and the testing of the d/h and sealing system.

The vessel is scheduled to be delivered to Frontier Cruises, Lim- ited, in October of this year. The 6,700-ton Frontier Spirit has an overall length of 365.8 feet, breadth of 55.7 feet, and capacity for 184 passengers. Propulsion is provided by two Daihatsu main die- sel engines with a power output of 3,300 hp at 720 rpm, providing a maximum crusing speed of 16.6 knots. Frontier Cruises was established last year as a joint venture company between MHI, Nippon Yusen Kai- sha (NYK), Mitsubishi Corpora- tion, Salen Lindblad Cruising in the U.S. and Hapag Lloyd in West Ger- many to offer expedition cruises to exotic destinations in the world such as the Arctic and Antarctic areas and Amazon River. Unlike luxury cruise ships, the Frontier Spirit will have a capability to cruise frozen sea and be equipped with equipment and facilities neces- sary for expeditions, such as a heli- port and landing boats. The ship has 82 large cabins with closets designed to hold clothes necessary for such special expeditions.
