What is Enhanced Survey Programme or ESP ?

(For bulk carriers & oil tankers)

1. Survey planning
2. Document file onboard
3. Improved procedures for thickness measurement
4. Harmonization between DD & renewal surveys
5. Extended intermediate surveys
6. Possible annual examination of tank/spacesphase out of CHS

Close up examination – details within inspection  range

Overall survey – report overall condition of space /structure & determine extent of additional close up surveys
                          
Suspect areas – prone to rapid wastage

Critical areas – vulnerable to substantial corrosion,  buckling / fatigue cracks

Substantial corrosion – wastage is in excess of 75% of allowable corrosion margins but within acceptable limits
