Rubb Cocoons Protect Military Cargo
Rubb Buildings recently completed its third major marine protection enclosure system for the US Military Sealand Command. The controlled environment "cocoon" system consists of a total of ten individual enclosures positioned on the Captain Steven L. Bennett, a ship owned by Sealift, Inc. of Oyster Bay, New York. The vessel is under long term charter to the US Military as part of its pre-positioning program.
The overall Rubb cocoon system aboard the Captain Steven L. Bennet measures approximately 100 feet wide by over 400 feet long with heights up to 38 feet. The system encloses over 1.2 million cubic feet and is fully insulated and sealed to protect expensive military cargo from the marine environment, and to allow regulation of the interior temperature and humidity. This latest cocoon is more than double the size of the average Rubb cocoon systems built to date, and the entire project involved over 15,000 person hours to design, manufacture and install.
The Rubb structure consists of a high strength hot-dip galvanized wide flange beam framework that is clad with 28 ounce and 32 ounce per square yard PVC coated polyester membrane panels. The system is designed for 100 mph wind speeds acting in combination with the substantial forces associated with heavy rolling seas.
The Rubb system has been proven through extended use in the Atlantic, Pacific and Indian Oceans as well as the North Sea, the Mediterranean Sea and the Persian Gulf.
The individual cocoon sections are provided with a wheeled track system that rides upon a standard railroad-type rail that is secured to longitudinal tubes fitted on the port and starboard container posts. This allows the cocoon sections to quickly "telescope" together to allow for access to stored cargo and efficient loading and off loading.
Rubb, a world leader in land based relocatable membrane clad structures, pioneered this type of cocoon system with Van Ommeren Shipping's Strong Virginian in 1992. This first cocoon was, in Van Ommeren's words, an "unqualified success." The Strong Virginian cocoon traveled hundreds of thousands of nautical miles prior to being retired to land-based use as part of a museum restoration project in the Netherlands in 1997.
David C. Nickerson, Vice President and General Manager of Rubb, Inc. states that "Rubb, to its knowledge, is the only company to successfully provide enclosures of this magnitude. We have also successfully supplied marine protection systems including floating structures for use as yacht storage enclosures and to protect fish farms".
The RUBB organization, with production facilities in the United States, Great Britain and Norway, is recognized as a world leader in the design, development and manufacture of relocatable structures.
