Coast Guard Certifies

First Passenger Sub

The U.S. Coast Guard recently certified the first passenger-carry- ing submarine, the 65-foot Atlantis

III, under Sub-chapter T of the rules and regulations for small pas- senger vessels. The certification of the vessel, which was built by Sub-

Aquatics Development Corporation, required unique adaptations to the rules.

The adaptations have produced guidelines that are expected to help simplify certification for additional submarines.

Peter J. Palladino has joined

SPD Technologies as project engi- neer responsible for the company's advanced new computerized battery monitoring systems.

Prior to joining the Philadelphia- based producer of electrical systems protection equipment, Mr. Palla- dino had been engineering manager for Megatran Electronic Power,

Bordentown, N.J., where he was re- sponsible for design and develop- ment of microprocessor based con- trol systems.

Hagglunds To Acquire

Dutch Crane Group

Hagglunds Marine & Offshore, a division of AB Hagglund & Soner of

Sweden, has signed an agreement under which it will acquire all the shares in the Dutch Kenz Cranes

Group.

Kenz Cranes is among the leading makers of offshore cranes in the range 5-100 t SWL. The group, which has about 60 employees at / factories at Zuiddijk in the Nether- lands and Great Yarmouth in Eng- land, has annual sales of approxi- mately $5 million.

The takeover creates interesting opportunities for Kenz Cranes through access to Hagglunds' world- wide sales organization. The pooling of the technical resources and expe- rience of the two enterprises will also strengthen their competitive position.

The activities of Hagglunds' ma- rine and offshore subsidiary in the

Netherlands, ASEA Hagglunds, will be integrated with Kenz Cranes.

Hagglunds' service to shipping in

Rotterdam will continue as before.

Hagglunds Marine & Offshore Di- vision is one of the world's leading manufacturers of deck cranes. The acquisition of Kenz Cranes secures a corresponding position in the mar- ket for offshore cranes.

With rain and sea clutter circuits OFF on PATHFINDER/ST ARPA, sea clutter extends 1.8 to 2 miles from ship, ice floe belts appear 320° to 35° additional ice clutter scattered beyond sea clutter 270° to 320° (Thick lines at 230° and 155° are RACONS).

With rain and sea clutter circuits ON, the radar picture is absolutely "clean" Sea and ice clutter are gone. All targets previously masked are clearly visible.

Thomson-Gordon Supplying

Rudder Bearings For Large

Single-Screw Motorships

A contract to supply rudder bear- ings for the largest single-screw mo- torships in the world was recently placed with Thomson-Gordon Lim- ited of Burlington, Ontario, Cana- da.

Worth over $76,000, the rudder bearings are to be installed on the five 3,800-TEU-capacity container vessels being built for American

President Lines at the HDW ship- yard in Kiel, West Germany. Mea- suring 869 feet by 129 feet, each ship is designed with two rudder bear- ings.

Cast from Thordon SXL elastom- eric polymer-alloy material, the bearings are among the largest ever made by Thomson-Gordon.

True Motion with

Electronic Plotting or ARPA.

Raytheon sets radar performance stan- dards for the 21st century with technolo- gy breakthroughs that virtually eliminate noise, interference and clutter, while rec- ognizing and displaying even weak tar- gets typically lost on other radars.

The heart of this improved radar system is Raytheon's exclusive five-stage signal processing.. .we call it Superior

Technology.

ST for short.

Combined with higher performance transmitters and receivers, and the latest raster displays, ST provides performance levels never before available. Now, with

PATHFINDER/ST, your vessels-and their crews-can have an important extra mea- sure of safety and efficiency, including a unique Safety-Coded CPA Circle, which shows course selections for safest CPAs.

PATHFINDER/ST is available as an

ARPA or a True Motion/Relative Motion display with Electronic Plotting. These displays can easily retrofit the displays in older Raytheon Bright Display Radar

Systems, and can be high-performance repeaters for radars of most other manufacturers.

When interfaced with an SNA-91 Integrat- ed Bridge Display, the PATHFINDER/ST

ARPA also becomes a key sensor/deci- sion-aid in a complete shipboard naviga- tion and control system.

Near-Perfect

Target Detection.

Using increased signal-to-noise levels, high dynamic range, precisely matched pulse bandwidths, and exclusive Rain

Rate circuits, PATHFINDER/ST receiv- ers faithfully capture target returns even in severe clutter.

PATHFINDER/ST multistage processing analyzes, compares, tests, and samples the received signal so that all detected targets, no matter how weak in signal strength, are distinguished from clutter and clearly displayed. 14 Maritime Reporter/Engineering News
