About This Project
We were chosen by a large, international cruise-liner company to carry out repairs and refurbishment on one of their heat exchangers.
The cruise ship has a freshwater generator system, which takes water from the sea and turns it into freshwater for use on board the ship for things such as showers, toilets and heating.
The onboard engineers reported to us that the freshwater generator heat exchanger system was failing due to a leak.
What We Did
There was no way we could work on this ship whilst docked, as it was planned to be in use to transport passengers on a cruise. We therefore had to use our experience to plan a way to work on the ship whilst it was sailing.
We sent a team of three engineers from our site in Sheffield to meet the ship when it docked in port and they stayed onboard to complete the work.
We established that the problem with the heat exchanger was that the old tubes had corroded, meaning they needed to be replaced completely with new tubes.
We ordered 1,880 new Ali-Brass tubes in advance and shipped them ready for our engineers to use. Our engineers then went and removed the existing tubes using specialist tools, and fitted the new tubes to the heat exchanger.
The system was then pressure tested and witnessed by the Chief Engineer onboard the cruise ship.
