Objectives

• Illustrate relationship between standards
  ClassgtESPgtCASgtCAP
• Cover LRs view of oil major vetting
  requirements
• Open discussion of class, statutory and CAP
  standards

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

6
Intangible benefits to tanker owners

• Opportunity to assess repair needs
• Facilitated contact between owner/charterer
• 3rd party assesses Oil Major requirements

Overview of CAP-LR

• An independent rating scheme of ships structure,
  machinery and cargo systems
• Allows owners, charterers, shippers and terminal
  operators to make objective judgements about a
  ships condition
• CAP-LR is not a classification requirement
• CAP-LR is not an endorsement
  nor a negation of classification

Overview of CAP-LR

• CAP-LR is part of the vetting programmes ofBP
  gt20,000 Tonnes gt15 Years Valid to next DD

• Preem gt5,000 Tonnes gt20 Years
• Repsol gt5,000 Tonnes gt20 Years
• Statoil gt 3,000 Tonnes gt15 Years Valid 3 Years
  CAP 2 lt 3,000 Tonnes have 4 Years CAP
  1 reduced scheme
• Vela gt20,000 Tonnes gt15 Years
• BP Repsol require CAP on hull structure only

9
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.

10
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

11
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

12
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

Thickness measurement analysis

• Submitted in LR TM software
• Migrated to CAP-LR to obtain ratings for
  individual members judged against as-built rule
  scantlings
• Structural members assessed are shell
  plating deck plating oil tight bulkheads web
  framing longitudinal stiffening fore and after
  peaks

18
Fatigue (optional)

• Screening assessment
• Based upon LR ShipRight FDA2
• Typical loading patterns
• Assumed corrosion rate
• Identification of potential hot spots
• Used to target inspection

19
Fatigue report format
20
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

21
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
