V/Z/////M/// 1. Save Fuel Costs with retro-fit: Run engine at lower RPM and lower HP, but achieve the same thrust and speed. 2. Increase dragging, towrope and bollard pull but keep the same speed and fuel usage. 3. Increase speed but keep the same thrust and fuel consumption.
That's why it is no accident that more and more builders and owners of
River Towboats, Ocean Tugs, Harbor Tugs and small Tankers specify the
Columbian Precision Ducted Propeller System. They know that with a
Columbian System astern they will beat the cost of downtime, frequent overhauls and repairs, because we stress optimum engineering. Our plate thicknesses, certified welding, insulated rings, heavy-duty ribbing and proper propeller selection all combine to avoid the common problems of cavitation, warpage, flexing electrolysis, leakage, corro- sion, puncture and inefficient performance.

Bethlehem Beaumont Shipyard
To Build Offshore Rig For
Houston Offshore International
Houston Offshore International, Inc. has ordered construction of an offshore oil drill- ing rig from Bethlehem Steel Corporation's
Beaumont, Texas shipyard.
Announcement of the contract was made by Jerry E. Chiles, president of Houston
Offshore, and Barry Long, acting general manager of the yard.
The new rig, which is the third offshore rig ordered in three years by Houston Off- shore, will be a jackup designed to operate in up to 200 feet of water. Work will begin this summer, with delivery scheduled for
Artist's rendition shows design of the cantilevered offshore drill rig that Bethlehem Steel Corporation's shipyard in Beaumont, Texas, will build for Houston
Offshore International, Inc. Work on the rig will begin this summer, with delivery scheduled for May 1979.
The unit will be similar to previous deep- water Bethlehem-designed, mat-supported jackup drill rigs but will have a cantilevered drill floor. This feature permits exploratory or developmental drilling from 15 feet to 45 feet aft of the platform while cantilevered over existing wellhead structures. With hook plus setback loads of 1 million pounds and full-size drilling equipment, the rig will be ideally suited for deep-well drilling in water depths ranging from 11 feet to 200 feet.
Mr. Chiles noted that the new rig for his company is only the second of its kind on order. He said, "We believe this unique de- sign will give Houston Offshore the utmost flexibility in serving the needs of our oil company customers in the Gulf Coast area."
The drilling unit will provide onboard, air-conditioned living accommodations for 52 employees.
The rig will consist of a buoyant upper platform hull 157 feet long by 132 feet wide supported by a mat foundation 220 feet long by 185 feet wide. Three 11-foot-diameter columns affixed to the mat and passing up through the platform will provide the means for the platform to be jacked above offshore waters to provide sufficient wave clearance.
