Marine Services Condition Assessment Condition Assessment Oil major requirements -more or less? Presentation by Graeme Blevins and Brian Henry Consultancy Services Group

Marine Services Condition Assessment Condition Assessment Illustrate relationship between standards: Class>ESP>CAS>CAP Cover LR’s view of oil major vetting requirements Open discussion of class, statutory and CAP standards Objectives

Marine Services Condition Assessment Condition Assessment Relative levels of inspections CLASS CAS ESP CAP

Marine Services Condition Assessment Condition Assessment Actual benefits of CAP to tanker owners Objective evidence of quality tonnage Opportunity to attract major charterers Wider selection of charters Combining class/ESP, CAS & CAP surveys

Marine Services Condition Assessment Condition Assessment Intangible benefits to tanker owners Opportunity to assess repair needs Facilitated contact between owner/charterer 3 rd party assesses Oil Major requirements

Marine Services Condition Assessment Condition Assessment Overview of CAP-LR An independent rating scheme of ship’s structure, machinery and cargo systems Allows owners, charterers, shippers and terminal operators to make objective judgements about a ship’s condition CAP-LR is not a classification requirement CAP-LR is not an endorsement nor a negation of classification

Marine Services Condition Assessment Condition Assessment Overview of CAP-LR CAP-LR is part of the vetting programmes of: BP >20,000 Tonnes >15 YearsValid to next DD + FATIGUE PetronasAll ships >15 YearsValid 30 months + FATIGUE Preem>5,000 Tonnes >20 Years Repsol>5,000 Tonnes >20 Years Statoil> 3,000 Tonnes >15 YearsValid:3 Years CAP 2 < 3,000 Tonnes have 4 Years CAP 1 reduced scheme Vela>20,000 Tonnes >15 Years BP & Repsol require CAP on hull structure only

Marine Services Condition Assessment Condition Assessment Oil companies requirements Confidence in the structure to survive 3 years to the end of service without reaching the stage that would need renewal under class requirements. The risks of failure from corrosion and from poor design through fatigue are to be specifically addressed.

Marine Services Condition Assessment Condition Assessment CAP Hull structure inspection Close-up inspection of hull envelope plating, all ballast & selected cargo tanks General examination of all other cargo oil tanks Ultrasonic thickness measurement of hull structure

Marine Services Condition Assessment Condition Assessment ESP Hull structure Inspection Close up of all ballast tanks Close up of 1 complete wing cargo tank Close up of all transverse bulkheads Close up of 1 transverse web in remaining wing cargo tank Close up of 1 transverse web in each centre cargo tank

Marine Services Condition Assessment Condition Assessment IMO CAS Hull structure inspection All web frame rings, in all ballast tanks All web frame rings, in a cargo wing tank A minimum of 30% of all web frame rings, in each remaining cargo wing tank All transverse bulkheads, in all cargo and ballast tanks A minimum of 30% of deck and bottom transverses including adjacent structural members, in each cargo centre tank Additional complete transverse web frame rings or deck and bottom transverse including adjacent structural members as considered necessary by the attending surveyor

Marine Services Condition Assessment Condition Assessment Other aspects of CAP-LR Machinery and Cargo –General examination of machinery and cargo equipment –Operational effectiveness of safety protection systems –Maintenance practices audit –Rating is calculated by weighting of relative criticality

Marine Services Condition Assessment Condition Assessment Report The CAP-LR report is a comprehensive statement of condition found The CAP-LR certificate contains individual ratings from 1 (high) to 4 (low) for: hull structure machinery cargo systems
