The Problem

Following the installation of a new High fog Fire Fighting system to upgrade the existing system on a cruise ship there was an area where the new system had to be tied into the existing. The works included the need to install two ne tee sections complete with inline isolation valves
The ship was in full service and was only in dock for a few hours. The modifications had to be carried out during the time she was docked. To complicate matters further, as the works were on the ships fire suppression system, it was imperative that the works went ahead without complication. Any delays could mean the ship would not sail and 3000 passengers would be delayed or have their cruise holiday cancelled. All the works were overseen from start to finish by a Lloyds Register inspector. He would have the final say as to whether the ship was sea worthy following the completion of the works.

The Solution

Allied Pipefreezing Services Ltd were contracted to carry out the temporary isolation of the existing Fire suppression system in order to allow the pipework modifications to be carried out. The system was frozen in two places holding back the entire ships fire sprinkler system. A small section of pipe was removed to allow the new pieces to be installed. APS held the Pipefreeze for 3 hours allowing the completion of the pipework modification.
The new sections incorporated two new tee sections complete with new isolation valves. The new tee’s were installed on each of the existing pipe open ends to which new isolation valves were fitted to the branches. A new section of pipe was then installed between the new tee sections. Once the works were completed APS allowed the freezes to thaw, putting the new section back into service. All works were inspected for leaks by the Lloyds Register inspector. The works completed passed with flying colours allowing the vessel to stick to its schedule and continue with its voyage at the planned departure time.
