Water Depth Under Dry Docks Maintained By Bethlehem Unit A U. S. patent for desilting equipment which assists nature in maintaining a given depth in a waterway has been awarded to Bethlehem Steel Corporation, Bethlehem, Pa. The accumulation of silt under dry docks and other deep draft installations has been a problem for years. The movement of silt in waterways is dependent on natural currents which must be of adequate velocity to main-tain given depths. Often natural velocity is de-creased by structures and other factors. The patented equipment is designed to pro-duce the required current velocity over a given area. It consists of a submerged electric mo-tor and propeller mounted on a vertical column which extends from the pier deck to the depth to be maintained. The column is rotated through an arc of 180 degrees for maximum coverage in the areas being protected. The desilting equipment runs intermittently and is timed to take advantage of natural currents produced by the tides. This equipment is presently in use at Beth-lehem's Hoboken, N. J., ship repair yard. Inventor of the equipment is Timothy E. Cummings, construction engineer in Bethle-hem's shipbuilding department. His invention has been assigned U. S. Patent No. 3,449,915. Special Control Equipment Corrects Containership's List Equipment which ensures that container-ships stay on an even keel during loading and unloading has been ordered for 11 vessels at a cost of about $480,000 from a Scottish instru-mentation manufacturer, Dobbie Mclnnes Ltd., Glasgow, Scotland. This system of tank gauges and valve con-trol equipment was first fitted to Associated Container Transportation's Act-1. Other ves-sels to be fitted with the system are seven be-ing built at West German yards and three be-ing built at British yards. Keeping a containership on an even keel is essential for locating the containers accurately in the guides of the ships' holds. The gauges in the system control the pumps and valves which transfer ballast between tanks. The sys-tem can also be used to improve stability at sea and for gauging quantities of fuel in tanks.
