Mitsubishi To Build Semisubmersible Rig For Ocean Drilling Ocean Drilling & Exploration Company and its Far East sub- sidiary, Odeco Nihon, have an- nounced the completion of a con- tract signaling the start of con- struction of a fourth self-propelled semisubmersible drilling rig. The rig, Ocean Kokuei (pro- nounced Ko-Ku-A), will be built by Mitsubishi Heavy Industries, Ltd., Hiroshima, Japan shipbuild- ing firm which completed Odeco's first self-propelled and semisub- mersible Ocean Prospector earlier this year. So far in 1971, Odeco has an- nounced that construction has be- gun on two semisubmersible units, the Ocean Voyager in Norway and the Ocean Victory in New Orleans. Another new unit, the Ocean King, a jack-up, is under construction at Vicksburg, Miss. According to Alden J. Laborde, Odeco president, the new multimil- lion dollar rig is scheduled for com- pletion in the fall of 1973. Like oth- er Odeco self-propelled semisub- mersibles, the Ocean Kokuei will have a rated water depth of 600 feet afloat and a rated drilling depth of 25,000 feet, Mr. Laborde said. The new unit will be like the forerunner of its class, the Ocean Prospector, but will incorporate BRING 'EM IN STRIP 'EM CLEAN MOVE 'EM OUT Some Turbine Talk With Russ Lemcke Men in the marine industry usually like to deal with facts and leave double talk to the politicians. But from time to time, we are guilty of some double talk our- selves. One such example is our use of the word "turbine," which usually brings to mind a prime power source like a steam or gas turbine. And for this, Web- ster would not be critical. But there are also two types of pumps and both are called turbines. Here is where the difference is: one type, the Regenerative Turbine, is a hori- zontal pump, commonly used as a boiler feed unit in small commercial buildings. The other type is the Vertical Turbine or "Deepwell Turbine" which is used in tanker and tank barge unloading, bilge and ballast services. Ironically, this Ver- tical Turbine is not a turbine at all but a vertical multi-stage diffuser case pump. Goulds manufactures the specialized "Autoprime" self-priming turbine as well as standard vertical turbines in Los An- geles in the newest and most modern pump facility in the world. The entire Goulds vertical line is designed for the heavy duty marine services. Some com- petitors have even accused us of over- design, and this is criticism we enjoy. In the next issue, I'll be talking more about what we've done and why we've done it. So when you want to bring 'em in, strip 'em clean and move 'em out, call for a Goulds vertical self-priming or standard vertical turbine for tanker and tank barge unloading.

Howlett also has floating cranes of various sizes and capacities to meet your specific needs.

New York—Bowling Green 9-8644 New Jersey—Union 6-1566 improvements such as increased propulsion horsepower, reduced wave resistance and better moor- ings. A principal feature of the new rig, also like other Odeco self-pro- pelled semisubmersibles, is its twin Kort nozzle type propulsion sys- tem, which will propel Ocean Ko- kuei ahead at seven knots and astern at three knots. The new rig will be 320-feet long and 266-feet wide, have 6,700 propulsion horse- power, and modern air-conditioned quarters for 81 men. The lower hull will have four parallel pontoons measuring 28 feet in diameter. Four 12-foot diameter and eight 24-foot diameter stabiliz- ing columns will be connected to the four pontoons. The tops of the columns which support the main deck are 120 feet from the base of the pontoons. Transverse strength for the new unit will be provided by four transverse tubes, two 18 feet in diameter and two 12 feet in diameter, along with the main deck structure. Ocean Kokuei will incorporate ABS Grade CS steel in its shell plating extending to the tops of the columns and in the principal deck girders, to provide safe operation under extreme low temperature conditions. It will be classed by ABiS under its "Rules for Building and Classing Offshore Mobile Drill- ing Units, 1968," for unrestricted service. New Spee-Flo Model For Airless Spraying Of High Viscosity Coating The Spee-Flo Company has intro- duced a new power actuated Ram model for airless spraying of heavy viscosity high-surface tension ma- terials. The big 940 Super PowrMas- tic has a capacity of four gallons per minute and a 40-1 ratio power system. It is designed to handle the heaviest sprayable coatings with full atomiza- tion and spray gun control. The PowrMastic is equipped with a new "Scooper Valve," a device which actually forces high viscosity materials into the pump foot inlet, and assures full priming on each stroke. The high 40-1 power ratio is accomplished without sacrifice in the delivery volume, because the unit is powered by a new, larger 8.5-inch air motor. This means that full, necessary working pressures can be reached for most materials at only 75 to 85 psi air input. Maximum working fluid pressures of 4,000 psi can be produced at 100 psi air input. The new unit is deluxe equipped with automatic oiler, moisture sep- arator, and high volume air regulator. Gun and hose assemblies are optional accessories. A high - efficiency stainless - steel 4-kw PowrMastic heater is also avail- able for attachment to this system for viscosity reduction, greater film build per spraying pass, or operation in generally low temperature condi- tions. The PowrMastic heater is de- signed for operations up to 6,000 psi.
