Dual-Fuel Vessel Gas Detection System - GDS1000/2000​

U.K Crowcon GDS1000/2000 is a comprehensive gas detection solution designed specifically for dual-fuel powered vessels. The system, via an integrated continuous sampling (GDS-2000) and control system GDS-1000 provides uninterrupted monitoring of key areas onboard such as the TCS (Cargo Control System), tank hold spaces, FGSS (Fuel Gas Supply System) room, double-wall pipes, bunkering stations, air locks, and areas above the engine.The system accurately measures gas samples after pre-treatment (e.g., dust and moisture removal), detecting key gas concentrations like hydrocarbons, oxygen, and hydrogen sulfide in real-time. With its addressable controller, automatic calibration capability, and data logging functions, it provides safety assurance compliant with international standards, making it a core component for the safe operation of gas carriers (LNG, LEG, LPG) and dual-fuel propulsion vessels.

Product Description

The system monitors key locations such as the TCS, tank hold space, FGSS room, double-wall pipe, bunkering station, air locks, and area above the engine. Via a continuous sampling system (GDS-2000), gas samples are dried, filtered, and pre-treated before being analyzed by the GDS-1000 control system. The system is equipped with an addressable controller, automatic calibration capability, and data logging/trending functions for the detection of hydrocarbons, oxygen, hydrogen sulfide, and other gases.
