I am having the gas rerun and that will involve a new opening for the pipe in the wall of the steel gas locker. Net result is a redundant hole that need plugging. I could I suppose get this welded but it is not that easy to access so are there alternatives such as: fibre glass, some sort of metal filler etc - that will be acceptable to the BSS.
Many thanks
Colin

Many thanks Colin As long as it's a good seal I would think there could be little that could be objected to. |

I suspect that fibreglass would not be acceptable. Whatever is used it must be impermeable to gas. While it is water tight fibreglass is not always impermeable to gas.
I would suggest that maybe a job for the professional who reruns the gas pipe work.

I think it should really be welded, but if it's a small hole I would just use some of that 2 part metal epoxy stuff like 'JB Weld'

Something like jb weld might be the way to go then as welding would be an horrendous job - if possible at all given where the hole is :-( Thanks |

Unlikely any leaking gas would get to the hole I would say, unless there was some sudden and a catastrophic failure of the cylinder,regulator/pipe work, which of course could happen. Just seal it as D9 suggests and I doubt there will be an issue with you BSS. |

Cover a 2p coin with sikaflex or other pu sealant and stick it over the hole.

What I have done is tapped the hole, screwed a bolt in, threads coated with a gas impervious sealant, nut & washer on the inside again sealed. |

Thanks for that and the link. Was interested in the bit in the regs about gas locker exterior side doors, which I have. It goes on about the seal between the doors and the locker body. Seems an odd requirement if the doors are on the outside of the boat and give access to and only to the gas locker. What is the point of having seals - surely any gaps only serve to help leaking gas escape overboard! Or have I got it all "A about F"

The gas locker on our previous boat was GRP as was the rest of the boat, I had to make good a bit of damage using GRP and never had any problems with passing the BSC.

Stick a bloody cork i it  As a few have said just cover it. The gas will not seep through the GRP if that is used unless it is held in there for a long time which i will not be ( unless you have no drain holes ) I would use a small GRP or metal plate over the hole and screw/stick it over the whole, use plenty of sealant if thats your chosen way. It be reat Infact i am doing by gas work now on my GRP boat and to get the pipe throught he side of the locker i will use a bulkhead fitting but when it fits i am going to do as i have said above as the bulkhead fitting will fill the whole and the round plate will be screwed and sealed over the smaller whole in the side of the locker. |

The chain locker on a Fairline Carrera 24 is also the gas bottle locker.
Lloyd's Register standard built boat that passes a BSS when a competent inspector looks at it.
