ABSTRACT
Figure 1 is the sketch of the arrangement of Increased Type according to Rules for Natural Gas Fuelled Ships (2013), merely showing the portside, which is set as the object of risk assessment.
It’s significant to know that pressure in gas supply lines within machinery spaces is less than 10 bar. Full penetration butt joint is one of the obvious features of Increased type. In addition, anywhere in machinery spaces including GVU is covered by two sets of gas detectors. As far as ventilation is concerning, the air space within the machinery spaces and GVU are equipped with mechanical extraction ventilation having a
