FIELD NOTE 01
Build your domain map
Create one page for each Pressure Vessel Inspector domain. Record the task, governing reference, common conditions, and evidence an inspector would document.
- inspection and examination
- corrosion and remaining life
- rerating, repair, and alteration
- code calculations and reference navigation
FIELD NOTE 02
Create a lookup index
A useful index points from field language to the exact reference area. It should reduce search time without replacing understanding.
- Term or field condition
- Reference title and section
- Related table or figure
- One-sentence application note
FIELD NOTE 03
Use a repeatable weekly rhythm
Short retrieval sessions outperform a single long review. Mix concept work, reference drills, calculations where applicable, and cumulative questions.
- Learn one domain
- Run closed-book retrieval
- Practice source lookup
- Complete mixed review and log misses
