x. 7.3.5 Gas Locker Drain Connection - This check has been enhanced to introduce a check for LPG cylinder locker drain pipe connections to be assessed the same as drain hose connections. The amended check now closes the loophole regarding the condition of drain pipe connections, linked to the potential for leaked LPG entering the interior of the vessel from a damaged connection. xi. 7.4.1 LPG Cylinder Movement Affecting LPG Hose - This check has been enhanced to make it clear that any LPG cylinder movement whilst in position in the LPG cylinder locker must not cause any pulling tight of LPG hose. The previous 7.4.1 check covered LPG cylinder movement potentially causing pulling of LPG pipework but did not address or pulling tight of LPG hose. The enhancement addresses the potential for leaked LPG entering the interior of the vessel from damaged LPG hose and hose connections in the LPG cylinder locker. xii. 7.4.5 LPG Cylinder Locker Repairs - This check has been enhanced to introduce requirements for LPG cylinder locker repairs, such that any repairs to cylinder lockers must meet the thickness requirements at check 7.4.5 and metal locker repairs must be made using a plate of similar metal and similar thickness, and these must be seam welded or brazed. Fibreglass locker repairs must consist of fiberglass fabric/matting and resin providing a similar thickness to the main body. LPG cylinder lockers need to be maintained with high integrity materials to minimise the potential for leaking gas to enter the interior of the vessel via inadequate repairs. xiii. 7.9.4 Hose Use On The Low-Pressure Side Of LPG Systems - This check has been enhanced to clarify where the use of LPG hose on the low-pressure side is acceptable, namely, to connect a LPG cylinder regulator and/or appliances to the LPG supply pipework. The enhancement addresses the potential for leaked LPG entering the interior of the vessel and supports current LPG installation practice. Note that ‘all-hose’ systems fully installed to ISO 10239 remain acceptable as they will comply with the checks at 7.9.6. xiv. 8.4.1 ‘Bullseye’ Decklights – The enhancement to this check was previously announced in June 2010 whereby examiners check for signs of heat damage to the surfaces surrounding ’bullseye’ decklights. xv. And 8.4.2 ‘Bullseye’ Decklights – The enhancement to this check was previously announced in June 2010 whereby examiners check for signs of heat damage to all curtains, blinds and other textile materials near to ’bullseye’ decklights. These two checks address fire risks and are now fully incorporated.
