PFS Ltd were asked to undertake a job to clean 28 cooling units on the Elgin platform in the North Sea, some of which were causing overheating issues.
Hugh MacKenzie, Technical Director at PFS Ltd, said: “We had a chemical treatment spread ready to deploy immediately. We know that we have a better designed HVAC cleaning system than the competition, backed up by an experienced offshore team. We acted fast and so far, we’ve cleaned 18 units in a 3-week trip. We plan to finish the remaining 10 during phase two of the project. We work to minimise shut down time of the units, often only needing to shut them down individually for 6-12 hours depending on the debris build up”.
MacKenzie added: “Because the HVAC units use seawater as a cooling mechanism, the marine growth reduces efficiency or in some cases, ceases the units heat transfer capability altogether when there is a substantial build-up. This problem can cause real issues when you consider the electrical switchgear, communications and computer equipment it needs to cool, not to mention the units used for the comfort of people on the platforms. My advice to operators is to get these units maintained sooner rather than later before they cause more serious issues for equipment and non-productive time.
