SIST EN 15609:2012

NOTE Hatches for inspection or maintenance of fuel tanks and LPG containers can be covered by uncut carpet, provided that all tank and container fittings can be inspected and maintained through other openings. 5.5.2.4 Where the container is secured to the craft by a container frame and/or container straps, the container shall be installed according to the requirements of XXAnnex AXX or XXAnnex BXX as appropriate. 5.5.2.5 Supports, chocks or hangers shall be separated from the surface of metal containers by a non-metallic, non-hygroscopic, non-abrasive material unless welded to the container. 5.5.2.6 Foam shall not be the sole means used to secure containers in place.

This requirement also applies to unconnected cylinders.
Where the cylinders are permanently fixed to the craft by container straps, the cylinder shall be fixed in accordance with the requirements of Annex C. 5.5.3.2 Cylinders shall be installed so that they are readily accessible. 5.5.3.3 Cylinders designed to be used on their sides (e.g. forklift truck type) shall be secured at the correct rotational angle (to ensure correct liquid off-take and pressure relief valve position). 5.5.3.4 For cylinders working on a vapour/gas phase, the pressure regulator shall be in accordance with EN 12864 and installed directly after the cylinder’s valve outlet.
5.5.4 Container lockers 5.5.4.1 Container lockers openable from inside the cockpit shall be opened only from the top.

This can be achieved by installing a non-return valve downstream of the remote-controlled service valve or manually operated valve on each container and a hydrostatic relief valve in the delivery tube, downstream of the non-return valves. An adequate filter system shall be placed upstream of the non-return valves to prevent the fouling of the non-return valves (see Figure F.1). 5.5.5.2 A non-return valve and a hydrostatic relief valve are not required where the back-flow pressure of the remote-controlled service valve or the manually operated valve in the closed position exceed 5 bar (see Figure F.2). In this case, the power supply to the remote-controlled service valves shall be wired so that no more than one remote-controlled service valve on the container can be open at any one time. The overlap time to allow switching from one container to another shall be less than 2 min. 5.5.5.3 Each container shall be provided with its own overfill protection device. 5.6 Components fitted to the fixed container 5.6.1 General requirements The components on and in the container shall be installed under the responsibility of the holder of the bonfire test certificate as described in EN 12805 or ISO 20826. 5.6.2 Remote-controlled service valve with excess flow valve on the container 5.6.2.1 The remote-controlled service valve with excess flow valve shall be installed directly on the container without any intervening fittings. 5.6.2.2 The remote-controlled service valve with excess flow valve shall be controlled so that it automatically closes when the engine stops or when the ignition is turned off. SIST EN 15609:2012

Where an instrument panel is fitted, a level indicator readout should be installed on the panel. 5.6.7 Fittings
The fittings shall be protected from ingresses of dirt and water. 5.6.8 Pressure relief device The pressure relief device shall be fitted in or on the container so that it discharges overboard directly or via the venting tube, where fitted. 5.7 Gas pipes, tubes and hoses 5.7.1 Gas piping and hoses shall be installed as high as practicable above the bilge water level and shall not be in direct contact to seawater. 5.7.2 Gas piping shall be routed at least 30 mm away from electrical conductors; unless the piping passes through a conduit with no joints, or the conductors are sheathed or in a conduit or trunking in accordance with EN ISO 10133 and EN ISO 13297.
5.7.3 Gas piping shall be supported by fixing devices or other means, such as inside vented, non-metallic, supported conduit or piping, to prevent chafing or vibration damage.
5.7.4 Gas piping and hoses shall be secured so that they are not subject to excessive stress.
