Product Description
Gas Detector Instrument Designed to Deliver Continuous Sampling Gas Detection for Offshore Installations and Vessel Types
GAC-M20 Continuous-Sampling Gas Detection Cabinet

Different vessel types and offshore installations have very different gas detection needs. This article outlines the typical applications and selection criteria for the GAC-M20 Continuous-Sampling Gas Detection Cabinet, and explains the decisive role of BV type approval.

Typical Applications
  • LNG cargo tanks
  • LNG fuel tanks
  • Other high-risk enclosed spaces onboard requiring continuous gas monitoring
Key Selection Criteria
  • Define the target gas and measuring range, then match the corresponding detector model
  • Choose the sampling method (point-type / continuous / circulating) according to the area risk level
  • Calculate the number of monitoring points and transmission distance to confirm channel and tubing coverage
  • Confirm power supply, interfaces and interlock requirements for compatibility with existing systems
  • Select only equipment with type approval from BV or other classification societies to ensure compliant installation
BV Approval Is a Non-Negotiable Selection Criterion

For vessels on international voyages and offshore installations, passing classification society inspection directly determines whether equipment can be installed onboard. GAC-M20 Continuous-Sampling Gas Detection Cabinet has obtained BV type approval as part of the gas detection and alarm system, making it a compliance requirement that buyers cannot ignore.

BV Type Approval - A Dual Guarantee of Quality and Compliance

In the marine and offshore sector, gas detection equipment can only be installed onboard after passing type approval by an internationally recognized classification society. This product holds a Type Approval Certificate issued by Bureau Veritas (BV), confirming that its design, manufacture and performance fully meet the classification requirements for international voyages and offshore installations.
