DCUK FM were contacted by SGL Systems regarding the ventilation cleaning of the main kitchen and laundry extract systems located on the Prosafe Bristolia Oil Rig which was located in Burnt Island on the northern shore of the Firth of Forth. The Prosafe Bristolia is a semi-submersible accommodation vessel. She can operate in benign and moderately harsh environments and can offer accommodation to a maximum of 587 persons, including facilities for recreation, messing, catering, office and plant areas. The rig was located approx. 1 mile from land whilst refurbishment works were being undertaken and part of the scope of the works was to undertake ventilation cleaning.
DCUK FM had to ensure that all possible equipment that may have been needed was shipped to the rig as this was only possible once a week. Whilst there wasn’t the need for BOSIET training all DCUK staff had to undertake a full medical to undertake works aboard the Bristolia.
Accommodation was provided for all DCUK FM staff whilst aboard the vessel of which the duration was 10 shifts. The kitchen extract system consisted of 5 separate canopies and associated ductwork that were all heavily contaminated with grease deposits. All systems were found to have fire rated ductwork with limited access for cleaning. DCUK FM had to fit an additional 35 access doors of various sizes to ensure that a TR19 compliant clean was undertaken to all areas of the ductwork, fan and associated mechanical equipment. The laundry extract system consisted of a single canopy with associated ductwork through to atmosphere. A rotary brush and Hepa vacuum unit were used to remove all deposits from the system after the installation of an additional 12 access doors. On completion of the works a full compliant TR19 report was provided to the client.
