Cleaning of process and utility systems

The cleaning of the process and utility equipment and systems forms part of the underlying strategy of planning and implementation. General observation shows that planning is the first essential element to a successful project. A prerequisite to good planning is establishing the goals and objectives at the very outset of the Abandonment Planning. These goals and objectives must be measurable against preestablished criteria so that the project can be evaluated to establish the level of success. Good planning can be viewed as a series of hurdles that one must clear to achieve the pre-set goals and objectives. Understanding of the legal, safety, environmental and legislative requirements allows the perimeters and constraints to be established before the final implementation of the, ''CLEANING OF PROCESS AND UTILITY EQUIPMENT AND SYSTEMS'' activities. The very subject of ''CLEANING OF PROCESS AND UTILITY EQUIPMENT AND SYSTEMS'' that may be considered straight forward, because some of these activities often form part of the normal platform operations performed from time to time on these systems. Before implementation of these activities, there must be an understanding of the ground rules and terminology used together with the resultant implications. A question that demonstrates the inherent problems, what does the term ''Clean'' mean? A limited list has been compiled to give some examples of what the dictionary defines the term clean to be; NOT DIRTY; UN-POLLUTED; DECONTAMINATED; STAINLESS; UNCONTAMINATED; SPOTLESS; VIRGIN; UNSTAINED; UNADULTERATED; STERILE; Liaison with Government departments during recent planning activities established a consensus for understanding the term ''Clean'' so that unreasonable expectation with regards to the level of cleanliness would not be greater than that which is practicable
