Discuss the differences between Enhanced Survey Program and Condition Assessment Program Survey?
Short answer
| Dimension | ENHANCED SURVEY PROGRAMME (ESP) | CONDITION ASSESSMENT SCHEME (CAS) |
|---|---|---|
| Treaty basis | SOLAS regulation XI-1/2; 2011 ESP Code (resolution A.1049(27)) | MARPOL Annex I regulation 13G; resolution MEPC.94(46) |
| Purpose | HOW periodical hull surveys are conducted | WHETHER a phase-out-liable tanker may continue trading |
| Ships covered | BULK CARRIERS and OIL TANKERS | CATEGORY 1 and CATEGORY 2 OIL TANKERS |
| Trigger | Every renewal, intermediate and annual survey | Request for continued service beyond 2005 (Cat 1) or 2010 (Cat 2) anniversary |
| Scope | Hull structure per Annex, hold/tank by hold/tank | Hull structure IN WAY OF CARGO TANKS, PUMP ROOMS, COFFERDAMS, PIPE TUNNELS, VOID SPACES, BALLAST TANKS |
| Timing | Ordinary survey cycle | ALIGNED TO ESP intermediate/renewal survey |
| Surveyors | Administration or RO | NOT LESS THAN TWO QUALIFIED EXCLUSIVE RO SURVEYORS with ESP experience |
| Acceptance criteria | Code’s close-up survey, thickness measurement, tank testing | RESOLUTION A.744(18) AS AMENDED |
| Output | Survey report file, CONDITION EVALUATION REPORT, certificates | CAS FINAL REPORT, STATEMENT OF COMPLIANCE (IOPP supplement) |
- Trap: ESP is a CONTINUING SOLAS survey method; CAS is a ONE-OFF MARPOL Annex I gate for phase-out tankers.
- ESP covers BULK CARRIERS and OIL TANKERS; CAS covers CATEGORY 1 and 2 OIL TANKERS only.
- CAS uses ESP criteria (A.744(18)) and runs CONCURRENTLY with ESP surveys.
- CAS requires TWO EXCLUSIVE RO SURVEYORS + independent RO/Administration review.
- Failure: ESP = survey not completed; CAS = REMAIN OUT OF SERVICE until valid Statement of Compliance.
