Megayacht Equipment

Offered By Kohlenberg —Literature Available

Originally established as a reconditioner and builder of steam engines in 1895, Kahlenberg Broth- ers Company now offers a diversi- fied line of marine related products, such as propeller shafts, propellers, rudder stocks, stuffing boxes, muff couplings, air/steam whistles and numerous variations of the

Kahlenberg airhorn for pleasure, commercial and military vessels. In particular, Kahlenberg Brothers has become a leading supplier to the megayacht industry.

Kahlenberg airhorns are accepted by both the U.S. Coast Guard and certified by the British Department of Transportation, as they are in full accord with the latest international convention ('72 COLREGS) Rules

Circle 216 on Reader Service Card for Safety of Life At Sea (SOLAS), adopted by the International Mari- time Organization (IMO).

Drew Launches Treatments

To Prevent Problems

In Marine Sanitary Systems

Drew's new biologically active treatments, "Ameroid Draingard" cleaner and drain treatment and

Ameroid "MSD-PAK" organic waste treatment, contain specially formu- lated strains of bacteria. These bac- teria not only digest organic waste to clear piping, but also help to main- tain the natural biological activity within marine sanitation devices (MSD), contaminated holding tanks (CHT), or other sanitary system fix- tures.

The bacteria in Draingard cleaner have the ability to digest the organic waste typically found in marine sanitry systems and prevent the formatin of new organic deposits.

Draingard treatment's neutral pH ensures that there will be no diffi- cult handling requirements. With regular use, time spent manually cleaning and replacing sanitary sys- tem piping is minimized.

MSD-PAK treatment, which is packaged in convenient, easy-to- dose, water-soluble packets, con- tains seven patented strains of ac- tive bacteria which ensure the rapid digestion of waste typically found in marine systems.

McNab Linear Fluid

Resistivity Monitor

Available In Three Ranges

McNab, Incorporated recently announced that a new fluid resistiv- ity monitor, available in a choice of three linear, automatically tempera- ture compensated, specific resis- tance ranges, has been added to the

Aqua-Purometer family of fluid qual- ity monitoring systems.

Dubbed the Aqua-Purometer I-

D, this new specific resistance moni- tor has been designed and manufac- tured along the same rigid stan- dards of quality and dependability as other Aqua-Purometers that have been performing admirably in the field year after year. The choice of one of three, factory set, linear ranges makes the API-D suitable for all types of fluid quality monitoring, including R/O applications, indus- trial process streams and effluent analysis. Hard to read, compressed semilog meter scales of other de- signs have been replaced by the API-

D's linear circuitry and linear meter scale with equal specific resistance graduations across the scale.

A special advantage of the Aqua-

Purometer I-D, says McNab, is the unit's automatic zero circuitry, which forever eliminates the need for zero calibration: the API-D auto- matically zero calibrates itself con- tinuously. Another feature is the hefty 5 amp control outputs, which may be accessed as both normally open and normally closed, powered or isolated, allowing connection to practically any common control or alarm indication devices. This alarm setpoint may be established any- where within the range of the in- strument, via an internal setpoint control the setpoint is meter dis- played for absolute accuracy and periodic verifying.

The Aqua-Purometer I-D is housed in a rugged NEMA 4X enclo- sure, while a see-through NEMA 4 front cover is available as an option.

The front panel contains a power switch, a large easy to read analog meter, and alarm and power indica- tors that can be viewed over a full 180 degrees F. The API-D has been designed for use with McNab's 3/4"

NPT specific resistance sensing cells, which feature built-in, high preci- sion, automatic temperature com- pensation and excellent sampling with reduced air entrapment.

Module On Piper Bravo

Platform In North Sea

Successfully Installed

With the successful installation of a 10,750-ton module on the Piper

Bravo oil platform in the U.K. North

Sea, a world record for the heaviest single object to be lifted by crane has been set.

The operator of the Piper Bravo development, Elf Enterprise, said the operation was like lifting a 12- story office block. The huge module was lifted into place on the steel support structure by the Heeremac crane vessel DB-102 and involved a 300-strong crew.

The average daily production ex- pected from Piper Bravo stands at 75,000 barrels and 34 million cubic feet of gas per day.

Sonsub Completes

Diverless Inspections

On Marathon Oil Platform

Sonsub Inc. has completed a con- tract with Marathon Oil Company which called for a total diverless subsea inspection using a Hysub 40

Remotely Operated Vehicle (ROV).

The ROV, which was mobilized aboard the American Express

Petromarine, conducted cathodic protection inspections, still photog- raphy, and video filming on Mara- thon Oil's West Delta Platform in

Block 143 of the Gulf of Mexico. The work was carried out in 369 feet of water on a turnkey basis.
