Towmaster Rudder System (continued)

The Towmaster Rudder System, now built in the U.S. by the Michi- gan Wheel Corporation of Grand

Rapids, Mich., under license from

Burness, Corlett & Partners, Ltd., permits a vessel to make a 180° turn in less than half the space required by a similar vessel fitted with con- ventional propeller and rudder.

The Towmaster Systems is de- signed for a ducted propeller and involves the use of triple rudders, and permits increased thrust as well as maneuverability.

Michigan Wheel has exclusive domestic rights to manufacture and sell the new system, which has been installed on numerous foreign-built vessels since the British marine en- gineering firm introduced it.

The Esperanza was built by Hou- ma Fabricators Inc., Houma, La.

The 99-foot harbor tug, owned by the Panama Canal Commission, has twin 1,500-hp General Motors EMD diesels and is rated at 90,000 pounds of foward bollard pull and 72,000 pounds of reverse bollard pull.

UCC/Rucker Introduces

Space-Saving Filters —Literature Available

New tank-mounted UCC Multi- flow suction or return filters are said to provide space saving and filter protection, and incorporate patent- ed, quick-change disposable ele- ments. Multipass testing to ISO 4572 standards has resulted in ele- ments rated at 25 to 40 microns, with efficiencies to 96.8 percent.

Four sizes offer flow capacities to 132 gallons per minute, with me- chanical or electrical condition indi- cators and NPT port threads.

Working temperatures range from minus 20 to 212° F, maximum oper- ating pressure is 100 pounds per square inch. A bypass valve, with opening pressures of 3 psi for suc- tion lines and 29 psi for return lines, prevents damage or collapse of the element.

M.A.N.-GHH Completes

Floating Dock For Iran

A 28,000-ton floating drydock was launched recently at the Nor- denham/Blexen, West Germany, dock construction yard of M.A.N.'s

Machinery, Plant and Systems Divi- sion (M.A.N.-GHH) on the Weser

River. The dock had been ordered by Iran for the Persian Gulf Ship- yard Project (PGSP) at a contract price of approximately $18 million.

Immediately after launching the dock, named Dolphin, was taken over by an oceangoing tug. Suitable stiffeners for heavy seas were in- stalled in the dock, which was rated and designed in GHH's Dock and

Shipbuilding Department. It is classed by Lloyd's Register of Ship- ping, which also approved the de- sign and surveyed the construction.

The Dolphin will be a major piece of equipment in a new shipyard to be completed soon at Bandar Abbas on the Persian Gulf under the

PGSP project. It is the seventh floating drydock built by M.A.N.-

GHH since 1976 for customers in the Middle East. Former docks de- livered to Kuwait, Qatar, and Saudi

Arabia are all working to the own- ers' full satisfaction.

The Dolphin has an overall length of about 787.4 feet, length over keel blocks of 754.6 feet, outer width of 172 feet, clear inner width of 134.5 feet, depth to upper deck of 58.4 feet, and immersion depth over keel blocks of 27.9 feet.
