Hi Scott,
I used to have a third party complete these inspections. They can select UT inspection points and you should inspect based on corrosion growth rate and not past 10 yrs. A third Party should also be able to use a standard report template that will include all the items in your checklist (vessel basic information, external condition, etc.)
For the PSVs, if they are small brass PSV, you could swap them in kind every 5 years.
