t 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

t Overview of CAP-LR

• CAP-LR is part of the vetting programmes of:

BP >20,000 Tonnes >15 Years Valid to next DD + FATIGUE

Petronas All ships >15 Years Valid 30 months+ FATIGUE

Preem >5,000 Tonnes >20 Years

Repsol >5,000 Tonnes >20 Years

Statoil > 3,000 Tonnes >15 Years Valid: 3 Years CAP 2 < 3,000 Tonnes have 4 Years

CAP 1reduced scheme

Vela >20,000 Tonnes >15 Years

BP & Repsol require CAP on hull structure only

t 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.

• 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

t 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
