Abstract: 

The paper is a detailed analysis of the devices used in measurements of hydrocarbon content on gas carriers during cargo tank gassing-up operations. The characteristics of the Riken Keiki GX-8000 portable gas detector used commonly on ships are described, the types of detection used in the device in relation to the detected gases are discussed, which made it possible to question the validity of using the detector for analysing the concentrations of large quantities of hydrocarbons on gas carriers. Also discussed is
a device enabling such analyses to be carried out much more accurately – the Agilent 490 Micro GC chromatograph, which will substantially improve the process of cargo tank gassing-up.
