The enterprise that became MMC started in the early 1940s as the Marine Plastics Corporation, making deck surfacing for tankers and military vessels. After the close of World War II, the name was changed to the Marine Moisture Control Company to reflect the firm’s rapid expansion as a manufacturer of equipment for the removal of moisture from shipboard machinery and cargo spaces.
Over the next several decades, MMC devices such as its corrosion preventing gear case dehydrators became standard components throughout the world’s fleets of tankers.
The MMC product line continued to expand with lube oil clarifier coalescers, hydraulic valve systems, draft indicating and tank gauging systems, cargo handling hose couplings, and other crucial items required by petroleum and chemical transport vessels.
