Gulf's Oil Recovery Vessel For Bantry Bay, Ireland

Built In Rhode Island By Blount Marine

With its bow secured, the 100-ton Bay Skimmer cruises at better than 9 knots on Narrangansett Bay. It carries a crane amidships to pick debris from its oil collection tank and to allow it to dou- ble as a general supply and patrol craft in Bantry Bay, Ireland.

Gulf Oil Corporation has ac- quired a newly developed oil re- covery vessel for its deepwater oil terminal in Bantry Bay, Ire- land. Besides requiring a highly effective oil recovery unit, Gulf also required a ship to patrol the waters near Whiddy Island, where the terminal is located, and peri- odically to patrol the full length of Bantry Bay, a round trip of about 50 miles.

The vessel, christened the Bay

Skimmer, is a fully equipped, 68-foot, 100-ton ship designed to patrol at speeds up to 9 knots and to recover oil up to 3 knots.

The vessel, custom built for Gulf

Oil use, is the prototype of a deepwater class of oil cleanup vessels that use a skimmer prin- cipal developed by JBF Scientific

Corporation in Wilmington, Mass.

Built by Blount Marine Corpo- ration, Warren, R.I., the Bay

Skimmer was designed by Ralph

A. Bianchi, president of JBF Sci- entific Corporation. Mr. Bianchi has designs for skimmer vessels up to 160 feet in length, and he believes that a skimmer that large could effectively clean up an Argo

Merchant spill.

Because there are no drydock- ing or heavy-lift facilities within a convenient distance of the ter- minal, the hull of the vessel was designed so that it may be beached in the event that repair or main- tenance work must be done below the waterline.

The Bay Skimmer utilizes the

Dynamic Inclined Plane (DIP)

Recovery System, collecting oil by forcing it under the surface of the water. Oil follows the sur- face of the moving inclined plane to a collection well underneath the unit. Buoyant forces cause the oil to naturally separate in the well, where it forms a deep oil pocket. Water-free oil is pumped from the top of the well to stor- age.

A double-chined displacement hull, powered with a twin propul- sion system, provides high cruis- ing speeds and excellent seakeep- ing characteristics. The bow is arranged to be opened during oil recovery operations and closed while transiting or operating as a workboat and supply vessel.

The first of this class vessel was launched in January of 1977.

The heart of the skimmer system is this dynamic inclined plane. Oil is pushed beneath the conveyor belt and back into a collection hold, where it separates from water. The belt moves faster than the for- ward speed of the vessel to prevent oil from backing up at the bow. 10
