Context
Where this sits.
Indian yards have adopted integrated construction — building hull, superstructure and internal systems as large pre-outfitted blocks, then welding them together with cabling and piping already run through. It compresses build time substantially, but it also front-loads the cost of error: a block that is out of tolerance is discovered at erection, when the fix is a schedule event rather than a rework ticket.
The problems
What actually goes wrong.
Manual visual inspection is the bottleneck
Every weld needs a visual assessment before any other NDT method is worth applying. That assessment varies with the inspector's experience, the light and the hour.
Blanket NDT is expensive and undirected
Radiography and UT applied uniformly cost the same everywhere and find defects unevenly. Risk-ranked triage puts them where they earn their cost.
Block tolerance discovered too late
Dimensional deviation found at erection is the single most expensive category of yard rework.
Traceability that does not survive to handover
Paper QA records are hard to reconstruct at delivery and harder at warranty.

National programmes
The frameworks this work sits inside.
India's maritime and defence modernisation runs through named programmes with defined funding routes. Knowing which one a requirement belongs to is half of getting it procured.
Outcomes
- Weld defects caught while the joint is still accessible
- NDT directed by risk rather than applied uniformly
- Block tolerance verified before the block leaves the shop
- Per-joint digital record that survives to handover and warranty
