Auxitrol Positioned For Bigger Piece Of Rador Tank

Gauging Market

Auxitrol S.A. of France is one of 13 companies owned by U.S.-based conglomerate Esterline. The compa- ny, which sees nearly all of its sales (an estimated 95 percent) emanate from France, is making a major push to present its line of tank gauging products to the U.S. market, hoping to capitalize on the projected barge building boom as well as fulfill the tank-gauging needs of other U.S. and U.S. controlled vessels.

In particular, the company is eager to present its TA 840 Radar Sensor, which was developed in cooperation with

Thomson-CSF, and is a new generation of tank level gauging system for marine appli- cations based on an Innovative Measuring Concept System.

The principle of the TA 840 Radar Sensor is the utilization of an intrinsically safe low- power processor unit which analyzes the antenna signal and converts the information into digital values. The TA 840 Radar Sensor is a totally sealed unit with a standard RS 485 field bus output signal, and for simplicity of installation, the sensor requires only two cable inputs. The TA 840 Radar Sensor is built for ease of installation and has two dedicated cable inputs. Power and RS 485 connections are provided by a six-core intrin- sically safe cable and a 10-core screened cable provides temperature and pressure con- nections. A third cable entry is provided for additional sensors.

GERMANY m noise signature.

DERA's research included the study of hydrodynamic perfor- mance; seakeeping, stability and manueverability; structural loading together with both under and above water vulnerability; signature aspects covering radar, IR, acoustic and magnetic predictions and com- bat system performance implica- tions.

Data derived from the demon- strator build and subsequent trials will be used to support other areas:

Scaling Accuracy: The demon- strator will be designed using tools where the extrapolation from mod- elling has been verified by their testing in the demonstrator.

Capability for Naval

Evolutions: The RN must have confidence normal RN operations

The first trials are expected to begin in the year 2000, and con- clude in March 2002.

The Phase 2 period, which will focus on derisking technologies (including a pre-planned mini refit to change the main propulsion motor with the main area of inter- est being in electric propulsion, where permanent magnet motors may be tested), will run from May 2000 through March 2004. The

Phase 3 trials will begin in May 2004.

Modelling shows the radar signature to be no worse than the monohull and greater layout flexi- bility could even reduce it. The posi- tioning of noisy machinery higher in the superstructure should result in a reduced underwater radiated would not be impeded by

Trimaran hull form. Of particul interest are replenishment at se towing, small boat operation berthing and handling.

Construction: A further benefi of building a large scale demonstra tor would be the experience gainei by British shipyards in the con- struction of trimaran hulls.
