Colt Industries To

Furnish Environmental

System For Riverboat

Colt Industries' unique vacuum- operated environmental protection system will be featured aboard a new riverboat being- built for

Greene Line Steamers, Inc., own- ers and operators of the famous

Delta Queen. The new vessel will be the first of a new fleet of pas- senger riverboats to be operated by

Greene Line.

The Water and Waste Manage- ment Operation of Colt Industries,

Beloit, Wis., has received a con- tract to supply the advanced sew- age system for the 400-passenger vessel. Known as ENVIROVAC, the system requires less than one- tenth of the water used in conven- tional systems.

The new 365-foot excursion boat will have a crew of 110. It is ex- pected to be in operation in 1975.

F.J. Eubank, vice president and general manager of the Colt opera- tion, said: "All of the sewage from the vessel will be handled by the new BNVIROVA'C collection sys- tem. This includes all of the 220 staterooms, crew quarters, and public toilets."

ENVIROVAC vacuum sewage systems can be installed in very limited equipment space. This is due to the limited water usage and smaller collection tank. Water storage capacity is also minimized.

The vacuum system operates with small electric motor driven pumps, which produce a constant vacuum of about 7^2 psi. Impor- tant to marine applications is the fact that small diameter plastic piping can be installed without slopes and can be worked around obstacles, because (gravity trans- port and grade dependence are not required. This facilitates placing piping in areas and at angles where it fits conveniently.

The new vessel will be built by

Jeffboat, Inc., for the owners,

Greene Line Steamers, Inc., at a cost of about $15.5 million. An offi- cial of Greene Line said the new pleasure vessel will be the largest and finest ever to operate on the

Mississippi River and its tribu- ^The order for the ENVIROVAC system includes a vacuum collec- tion tank with a 4,000 gallon ca- pacity, two macerator units, 320 toilets, two sewage discharge pumps, vacuum equipment and all necessary controls.

The vacuum transported sewage is pumped to the large divided storage tank where it is macerated.

At this point, the sludge is dis- charged to the oiLfired steam boil- ers and incinerated.

Esso Adds Barges

To Service Ships

In Japanese Ports

New lube oil barges in Osaka

Bay and Tokyo Bay have tripled the Esso bulk delivery capability in these areas.

The Esso Osaka Maru is a 130- ton barge with six tanks and space on deck for 100 drums. The Esso

Yokohama Maru is a four-tank 100-ton barge which carries 50 drums on deck.

The two join 'the 65-ton Esso

Kobe Maru and the 50-ton Esso

Tokyo Maru, respectively. The two smaller barges 'have been in service since 1969.

The Esso companies are said to deliver lubricants in bulk at more than 150 ports around the world. Nearly half the company's worldwide marine lubricant deliv- eries are made by pumping in bulk directly into ships' tanks.
