IR-CAP Condition Assessment Program Indian Register of Shipping
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.
Ship Charters Insurers Terminal Operators Cargo Shippers IR-CAP Service Assessment is carried out on as-is-basis, considering all repairs & renewals that have been carried out during the CAP survey Detailed documentary evidence is now available to all interested parties. 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.
Benefits to Ship Owner… The Ship owner can obtain better charters by demonstrating better quality of his ships. The CAP survey also provides the ship owner, a basis to plan the maintenance that ensures continued asset utilization.
What is Special about IR-CAP ? Each “ System” is rated based on the ratings of various sub-systems/components. Each component is rated considering all its relevant attributes, together. IRS surveyors are required to examine and rate each such attribute, separately, for all components. Specially designed software enables quick analysis and identifies the repairs that are required to secure the desired CAP Rating.
Anchor, Cable, Windlass, Rudder & Steering Gear, Weather-tightness, Shipside valves CAP Rating Process - Hull Local Strength Rating Total Hull Rating Longitudinal Strength Rating Satisfactory survey of Hull Fittings and Tank Testing is a pre-requisite !
Local Strength Rating Process Compartments in Cargo region + APT & FPT Ship A Compartment Rating process starts at Panel Level The Compartment Boundaries Structural Panels Plating + Secondary Stiffeners + Primary Girders
Overall survey Close-up survey Local Strength Rating Process Dry-dock External Examination Local Strength Rating of Each Panel Internal Examination Thickness Measurements
General condition Buckling, Indentations, Cracks Pitting, Localized thinning Wastage Coating condition Good, Fair or Poor Anode condition Good, Adequate, In-adequate Attributes that are reported from External and Internal Examinations These attributes are considered together with the Thickness Measurement to rate each panel
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.
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.
Longitudinal Strength Rating The software also helps evaluation of various repair options to improve the longitudinal strength, where required, in an optimum way.
CAP Rating Machinery / Cargo Systems
CAP Rating – Machinery / Cargo Systems Overall Survey Machinery Rating Total Machinery Rating Functional Test Predictive Test Maintenance Rating Audit of Maintenance Practices
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
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.
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
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 Job Cards are prepared by grouping the machinery into well defined systems - Propulsion System etc.
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
Vibration Measurements : Locations for Reciprocating Machinery 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
Vibration Measurements : Locations for Rotating Machinery • 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
Vibration Measurements : 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.
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
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
