Hitachi Zosen Completes

LPG Carrier

Antwerpen Venture, a 39,000-cu- m LPG carrier ordered by Cedonia

Shipping, was completed by

Hitachi Zosen's Ariake Works. The

LPG carrier is Luxemborg regis- tered and classed by DNV. It fea- tures three cargo tanks construct- ed of steel for low temperature ser- vice. The tanks are also designed for the transport of other liquefied gases, including ammonia and vinyl chloride monomers. The ship features a central control station, which monitors and controls both cargo-handling equipment and the engine plant. Positioned in the wheelhouse, the system allows for one-person operation. Powered by a Hitachi Zosen MAN B&W diesel engine, the 25,337-gt ship is pow- ered to 19.7 knots.

New Insert Provides

Continuous Level Indication

For Deep Tanks

For deep tank monitoring over 20 ft., GEMS offers the Roll Out

Linear Insert (ROLI), which was designed to offer accurate measur- ing of true level within + .5 in. The patented ROLI is, essentially, a flexible version of the voltage divider/processor insert assembly used in Gems Sensors' standard transmitter assemblies. While the

ROLI system is normally used to measure liquid level in tanks deep- er than 20 ft., it can be installed in tanks of any depth.

Gearbox Allows For Added

Cargo Space

Valmet Power Transmission was recently chosen by Stolt-Nielsen to provide the propulsion gear drive for its chemical tanker under con- struction in Italy. The tanker, the first of three ships, will be deliv- ered in August. The Valmet reduc- tion gearbox chose has a "locked- train" system for increased redun- dancy and safety. The gearbox has a fabricated steel housing, which allows for flexible layout possibili- ties and fitting the gearbox into a limited space. This efficient space utilization allows for, in the end, optimal use of cargo space.

Infrared Gas Analyzers For

Oil Tanker Pumprooms

Opus 8000 is an integrated gas and temperature monitoring sys- tem from TQ Environmental pic.

The system continuously monitors the atmosphere in the pumproom for dangerous levels of hydrocar- bon gas, while the PT100 probe provides continuous temperature monitoring of the cargo pump bear- ings.

The infrared gas analyzers are designed to provide accurate, reli- able monitoring. Due to the ana- lyzers' infrared source, there is reportedly no requirement for re- calibration during the lifetime of the sensor. The gas detector can operate in an inert gas atmos- phere.

The ability to communicate and integrate our system with other monitoring systems increases efficiency and safety on the dock. Therefore, we have developed our docking system to integrate with the following systems: • Docking • Vessel Tracking System (VTS) • Mooring Line Tension Monitoring • Drift Off • Cargo Information • Environmental Sensors

DUAL MODE OPTION - Laser can be combined with radar.

REDUNDANCY OPTION - Both laser and radar data are recorded and validate each other.

SAFETY - Engineered to operate in Intrinsically

Safe Environments.

STATE-OF-THE-ART - From the company who manufactures sensors for NASA.

EXPANDABLE - System can be used with existing equipment or expanded to add new equipment such as wind, current, and mooring line sensors.

REAL TIME DISPLAY - Pilot and Captain monitor the ship's movement in real time.

PERMANENT RECORD - All distances and speeds are recorded for future reference or incident reconstruction. 46 Circle 245 on Reader Service Card Maritime Reporter/Engineering News
