VIS Alarm System On

Martinac-Built Trawler

Proves Dependable

The main machinery and other vital equipment aboard the Martinac-built trawler Chelsea K is monitored by a Vessel Information Systems' VIAS 128-System as its primary alarm system.

Built by Martinac Shipbuilding

Corp. in Tacoma, Wash., for owner

Ocean Dynasty Limited for fishing in the icy Bering Sea off Alaska, the 150-foot trawler Chelsea K must have extremely dependable machin- ery and equipment. A critical part of the electronics aboard the Chelsea

K is her primary alarm system, the model VIAS system-128 from Ves- sel Information Systems, Inc. (VIS).

The VIAS system-128 was in- stalled with 128 sensors to monitor the main engines, gears, genera- tors, AC and DC electrical systems, hydraulics, bilge compartments, fire detection, fish holds, pneumatics, tank levels and freezer tempera- tures. VIS color CRT display sta- tions are located in the pilothouse and in the control room where cap- tain and engineer can independently monitor the performance of the criti- cal machinery throughout the ves- sel.

According to Peter Trogdon at

VIS, "The Chelsea K is an excellent example of today's new breed of ves- sels which depend on sophisticated electronics, made simple to use, yet built especially for marine use."

The pilothouse has eight full color monitors which are used for various functions ranging from fish detec- tion to the VIS monitoring. All of these systems were chosen carefully by the captain and owners to bring critical information to the pilot- house. The captain is presented with all the information and then makes decisions based on what he sees.For free literature on the VIAS

New Helconic Thrusters

From Omnithruster Suited

For Wide Range Of Craft

Santa Fe Springs, California- based Omnithruster Incorporated, a leader in waterjet propulsion and maneuvering systems, recently in- troduced a new series of thrusters suited for a wide variety of vessels.

Helconic thrusters are a unique design developed by Omnithruster

June, 1992 that is energy efficient and compact in size.The acronym "HCT" describes a helical seawater flow pattern in- side a conical chamber that results in high kinetic energy emitting from multiple tangential discharge ports.

There are sizes ranging from 7 to 450 kilowatts (10-600 hp).

Developed at the Omnithruster

Santa Fe Springs facility, these thrusters are particularly designed for shallow-draft vessels such as patrol boats and high-speed planing hulls that require side thrust ma- neuvering when they are in a dock- ing mode and require low-speed pro- pulsion when operating in harbors.

Their unique design also makes them particularly adaptable to fish- ing vessels, large yachts, workboats, offshore supply boats, tugs and ocean research vessels up to 300 feet in length.

The thrusters are made to oper- ate with either constant or a vari- able shaft speed that does not have to be reversed to change thrust di- rection and can be operated in a manner similar to a controllable pitch thruster with an accessory con- trol system.

A special adaptation of the HCT thruster enables the vessel to have forward propulsion capability, ei- ther as back up for the main propul- sion or as low-speed drive.
