Ircap program
- 1. IR-CAP Condition Assessment Program An Indian Register of Shipping Program
- 2. IR-CAP Service Independent assessment carried out at the request of ship owner. One or more aspects, viz. Ship’s Structure, Machinery & Cargo Systems can be assessed – as desired. The extent of survey is larger than that carried out at ESP or CAS survey and the Report is very detailed.
- 3. IR-CAP Service Detailed documentary evidence is now available to all interested parties. Assessment is carried out on as-is-basis, considering all repairs & renewals that have been carried out during the CAP survey They can now judge the condition of vessel better & have better confidence on her ability to provide good service without any repairs in the near future. Insurers Ship Charters Cargo Shippers Terminal Operators
- 4. Benefits to Ship Owner… The CAP survey also provides the ship owner, a basis to plan the maintenance that ensures continued asset utilization. The Ship owner can obtain better charters by demonstrating better quality of his ships.
- 5. What is Special about IR-CAP ? IRS surveyors are required to examine and rate each such attribute, separately, for all components. Each “ System” is rated based on the ratings of various sub-systems/components. Specially designed software enables quick analysis and identifies the repairs that are required to secure the desired CAP Rating. Each component is rated considering all its relevant attributes, together.
- 6. CAP Rating Process - Hull
- 7. CAP Rating Process - Hull Local Strength Rating Longitudinal Strength Rating Total Hull Rating Satisfactory survey of Hull Fittings Anchor, Cable, Windlass, Rudder & Steering Gear, Weather-tightness, Shipside valvesTank Testing is a pre-requisite ! and
- 8. Local Strength Rating Process Ship A Compartment Compartments in Cargo region + APT & FPT The Compartment Boundaries Structural Panels Plating + Secondary Stiffeners + Primary Girders Rating process starts at Panel Level
- 9. Local Strength Rating Process
- 10. Local Strength Rating Process Dry-dock External Examination Internal Examination Local Strength Rating of Each Panel Overall survey Close-up survey Thickness Measurements
- 11. Attributes that are reported from External and Internal Examinations General condition Buckling, Indentations, Cracks These attributes are considered together with the Thickness Measurement to rate each panel Wastage Pitting, Localized thinning Coating condition Good, Fair or Poor Anode condition Good, Adequate, In-adequate
- 12. Typical Job card for input from Surveyors Our software enables us to quickly prepare the required “Job-Cards” which are sent to the attending surveyors.
- 13. Longitudinal Strength Rating The software enables quick assessment of the available Longitudinal Strength, at various sections in the cargo region Available Strength is then compared with that required at the location. Longitudinal Strength Rating for the Vessel = the poorest rating obtained.
- 14. Longitudinal Strength Rating The software also helps evaluation of various repair options to improve the longitudinal strength, where required, in an optimum way.
- 15. CAP Rating Machinery / Cargo Systems
- 16. CAP Rating – Machinery / Cargo Systems Overall Survey Functional Test Predictive Test Audit of Maintenance Practices Machinery Rating Maintenance Rating Total Machinery Rating
- 17. Overall Survey / Function Test Each machine is examined as per the items identified on the Job- cards Function test of each machinery is witnessed and it’s current capability assessed
- 18. Overall Survey / Function Test Overall Survey •Examination of each machine component for any deterioration, corrosion, wear etc. •Verify the condition of instrumentation, and •Note presence of any leakages, etc.
- 19. Overall Survey / Function Test Functional Testing • To verify that the intended function of the machinery is being performed satisfactorily • Verify the Operational Parameters / Measure the output and • Verify the functioning of safety devices
- 20. Job Cards are prepared by grouping the machinery into well defined systems - Propulsion System etc. Machinery job cards Note the detailed list of components for each machinery unit, for which information is reported These job cards prepared by H.O. for each ship, and are filled up by the surveyor performing the survey
- 21. Predictive Testing All machinery is subjected to predictive testing, as applicable, to ensure no hidden defects exist Depending on the machinery one or more of the following tests employed: •Vibration measurements •Used oil analysis •IR ( Insulation Resistance) Measurement
- 22. Vibration Measurements : L – Left hand when facing the coupling flange R –Right hand when facing the coupling flange 1 – Machine end of mounting 2 – Crankshaft level 3 – Top end of frame A – Coupling end B -- Mid machine C – Free end of machine Locations for Reciprocating Machinery
- 23. Measurements at : Motor Drive End Motor Free End Pump Drive End Pump Free End At each location: a = Axial readings x & y = Radial readings 90 deg apart in horizontal plane Locations for Rotating Machinery Vibration Measurements :
- 24. Measured vibration levels are compared against acceptable levels and ratings assigned. Acceptable levels adopted are derived from ISO Std. 7919, and from our past experience. Vibration Measurements :
- 25. Audit of Maintenance Practices The audit verifies that: Maintenance routines are as per manufacturer’s recommendations and good engineering practice Maintenance routines are carried out as per schedule and records maintained A good system of Inventory Control for spares and stores exists for maintenance activity
- 26. In Summary… IR- CAP is a comprehensive scheme for assessment of Tankers The implementation of the scheme is also as disciplined Well Accepted by our clients as a Value Adding Service Another example of Quality Service from IRS
