cally extendible knuckleboom and fixed booms, both box and lattice, are available. With special features such as inorganic paint to withstand salt-laden, corrosive environments, they are built to provide years of trouble-free service.

Pettibone has been building and improving cranes for the marine in- dustry since 1964, so built-in fea- tures are the result of more than 20 years of design work. Today, as part of a continuing research and devel- opment program, the company has a list simulator for safety testing of cranes manufactured for shipboard applications.

The Solus vessel Tengar, one of a fleet that services Royal Dutch Shell offshore drilling platforms in the

South China Sea off the coast of

Borneo, is equipped with a model 40

PMp Pettibone Marine Krane.

Mounted on the main deck forward of the hatch, the 40 PMp provides needed reach with a 110-foot boom and 360-degree rotation. Its remote power pack is installed below deck, and controls are within easy reach of the operator, whose cab provides full view of the work area. Like all

Pettibone pedestal cranes, the PMp 40 is available with American Bu- reau of Shipping certification.

RAYTHEON OCEAN

SYSTEMS

Raytheon Ocean Systems Compa- ny of East Providence, R.I., manu- factures the LOADMAX® multi- point digital loading computer that is designed to aid ships' officers in planning safe, optimum vessel load- ing. The front panel display of the desk-top unit is readily configured for any type ship. Information on draft, stability, and hull stresses for any loading condition can be calcu- lated quickly and accurately.

Several models are available ac- cording to need. The Loadmax 100 computer performs draft, shear force, and bending moment calcula- tions only, and is intended for car- riers where stability computations may not be required.

The model 200 unit performs sta- bility calculations, as well as those for draft and hull strength. Special programs are available for LNG and

LPG ships, integrated tug/barge units, and containerships.

The Loadmax 300 computer pro- vides for cargo specific gravity en- try, cargo volume entry with auto- matic conversion to weight, and au- tomatic variable VCG and free sur- face corrections for carrying levels in cargo, ballast, and fuel oil tanks.

For integrated tug/barge systems, the Raytheon computer can provide calculations for tug alone, barge alone, and tug/barge joined.

REEL-O-MATIC

Reel-O-Matic Systems Inc., of

Wrightsville, Pa., offers a variety of machinery to the marine industry.

One of the most popular pieces of equipment is the series CPD or cus- tom power drum. This unit is con- structed of a fabricated steel drum mounted in bearings with various drive styles available. These ma- chines are built to customer require- ments for size and capacity.

The CPD is designed primarily for storage and winching of cables and lines in marine usage.

A special weather-proofing pack- age for shipboard environment is also available. This package in- cludes stainless steel shafting, total- ly enclosed motors and controls, sealed bearings, and galvanized un- dercoating with rubberized paint.

These same corrosion-preventive measures can be applied to any of

Reel-O-Matic's equipment that have applications throughout the marine industry.

Another frequently used piece of equipment is the RS/VS series of shafted stationary coiling and reel- ing machines. These units can be bolted or welded to the deck of a ship to pull any flexible material onto a reel or coil. The RS/VS is offered with various drive configu- rations to suit any particular need.

Reel-O-Matic's HJ/KVS series mobile reeling and coiling machine also is often used aboard ship be- cause it has all of the outstanding features of the RS/VS and, in addi- tion, it is mobile. A configuration of locking wheels and swivel casters allows this machine to be easily moved from job to job.

SCHOELLHORN-ALBRECHT

The Schoellhorn-Albrecht Divi- sion of St. Louis Ship manufactures the 1824 family of deck capstans that have been in service for more than 40 years. These capstans have fully normalized and stress-relieved cast steel barrels and right-angle worm gear housing. They are driven through a structural-frame- mounted, spur-gear-reduced, right- angled worm gear drive. The worm drive operates in a continuous oil bath, and the bronze bushings have pressurized grease fittings.

Primary power is provided by a 30-hp marine electric motor fitted with a 120-percent torque capacity magnetic disc brake.

The 1824 capstan is designed to provide 10,000 pounds of pull at 55 feet per minute, and 20,000 pounds at 28 fpm. Ultimate pull is 55,000 pounds, with an ultimate static holding capacity of 100,000 pounds. to turn your ship around in a hurry. be gone again on schedule.

Other deck capstans with barrels of 14 to 24 inches, driven electrical- ly, pneumatically, or hydraulically, are available. Also featured in a new brochure available from Schoell- horn is a smaller, totally redesigned capstan/carpuller. These surface- mounted units, designed for less se- vere marine and industrial applica- tions, are available with operating capacity from 5,000 to 15,000 pounds at 30/50 feet per minute.

SMATCO

The SMATCO, Inc. Division of

TBW Industries of Houma, La., supplied complete shipsets of Nor- winch low-pressure hydraulic deck equipment for two anchor-han- dling/tug/supply vessels built by

Halter Marine for Penrod Drilling of Dallas. The two 225-foot, 12,280- bhp vessels are being used primarily for long-distance towing of semi- submersible rigs, and other towing and anchor-handling tasks.

The Kodiak I and Kodiak II are each equipped with one 4S-250-2T 250-ton waterfall hydraulic anchor- handling/towing winch. This unit is powered by four Norwinch low- pressure hydraulic motors, and is arranged to enable either of the drums to provide full pulling power.

Both drums can provide half pulling power simultaneously, and they can be operated independently of each other in either direction of rota- tion.

This system gives the advantage of allowing a controlled maximum load on the lines, preset by the oper- ator. The winch is also equipped with a Norwinch high-power, hy- draulic dynamic braking system, which provides control of speed and pull.

Also on board is a type S-50-1T 30-ton hydraulic anchor winch type bow windlass. This unit is powered by one Norwinch low-pressure hy- draulic motor, and consists of a declutchable drum, a declutchable cable lifter for 38-mm chain, and two fixed warping heads. The ves- sels also have two hydraulic tugger winches, type MV-12. In addition, each vessel has two hydraulic cap- stans, type C-9.
