A cooler unit on an offshore platform was due to be removed for planned maintenance. The lift path of the cooling unit was blocked by a 2” Copper Nickle Deluge line so the client was going to have to move it… The deluge line is critical so needs to be reinstated as quickly as possible. When the cooler unit completes maintenance there will be a requirement to move the deluge line again.
The deluge line was cut and 2 x Lokring Copper Nickle Flange connections were installed on to the pipes to create a break point in the line. Lokring flanges require NO HOT WORK and can be installed even with moisture present in the pipe which means no drying required after draining.
