Dehumidification, Sealing, Monitoring System Installed On MSC Ship By L&C
L&C Associates, dehumidification specialists, recently announced the completion of the installation of an innovative dehumidification, sealing, and monitoring system for the prepositioned, general cargo ship M/V Advantage, chartered to the Military Sealift Command (MSC) to carry cargo.
The system, designed and installed by L&C to meet MSC specifications, consists of monitoring and dehumidification systems which service each of the vessel's four holds.
A major component of the system is a Cargo Environment Monitoring System (CEM), which includes air flow sensors, and humidity sensors. The area monitored by the CEM exceeds 1.2 million cubic feet. Other features of the CEM include a computerized retrieval and recording system, required by MSC specs, designed by L&C. This unit compiles and computes functions and transmits data to a logger located in the deck office. Data can be downloaded via PC to floppy disks or nonvolatile EEPROM storage cartridges.
The computer and monitoring systems have been tested extensively for reliability in the marine environment and have been designed to retain all data despite a loss of power to the ship.
In order to maintain an acceptable environment within the holds, dehumidified air is ducted into the cargo areas and is controlled by humidistats. L&C, using their patented Protective Sealing System, sealed the hatch covers and the hold ventilation system. Sealing the control area is the only way to maintain the integrity of the dehumidified spaces, and L&C's Protective Sealing System (PSS) has proven to be an effective and economical method of protection from moisture damage. L&C Associates, North Hampton, N.H., is an industry leader in the design and installation of dehumidifications, sealing and monitoring systems for the marine market.
