How Much Time will the Inspection Take?
Inspections are completely dependent on the level of cleaning and the significance of the indications found. If a piece of equipment has been thoroughly cleaned and is defect free, the inspection is a relatively quick and low-cost service that can provide information and documentation to support required inspection intervals. Poor cleaning, extensive damage, and limited access can double or triple inspection costs in some cases. The best way to estimate the time an inspection will take is to consider the age of the equipment, the findings from the previous inspection and to hire contractors that are experienced with the required tasks. Recon cost estimates will be based on average time for required tasks unless documentation or previous findings are provided.
How Much will an Inspection Cost?
Costs will vary according to the tasks that need to be performed. In general, inspection personnel will range from 70.00 – 100.00 an hour, similar to the costs of other journeymen level field workers. Additional costs include travel KM, Living out allowance, and equipment costs.
What are the surface requirements for UT Scanning?
Approximately 0.040″ pit depth can be enough to cause significant degradation of the sound wave, leading to attenuation, deflection, and diffraction. In cases where general pitting exceeds what appears in our image grinding may be required. Grease, water, and other contaminants will limit UT scanning. High and low temperatures may limit couplant that can be used.
Does this job require a safety attendant / manwatch?
Any confined space entry requires a safety attendant that will monitor activities inside the space without engaging in any other tasks. The attendant will be equipped with a communication tool to contact rescue personnel in case of an emergency.
There are 3 basic options when it comes to manwatch:
1. Client provided in-house
2. Third party rescue
3. Recon provided manwatch.
Consider the type of entry that is being performed, the product contained, the availability of rescue and the conditions inside the confined space. Before entry a full analysis of the work is required, this includes the tasks being performed, who will be entering, what gear is required, rescue planning, ensuring adequate levels of training, and review of company rules when determining how to provide the required level of safety with confined space entries. These will vary according to each site.
Entrants may require SCBA, 1/2 masks and/or continuous atmospheric monitoring.
What are the cleaning requirements?
When determining cleaning requirements it is important to consider the expected damage mechanism and how difficult the expected defects are to find. Small pits, cracks, and defects will require additional cleaning. Internal corrosion, pitting and damage may limit inspection, this may require additional mechanical preparation of the surfaces. Consideration should be given to how difficult it would be to access this piece of equipment again, what are the costs associated with downtime and is this a critical or secondary asset. Due to the complicated nature of equipment isolation, it is best to not go through a difficult clean only to finish short of completing the job properly.
