Classification Society
2,500 employees in 300
offices in 70 countries
Extensive marine & offshore
experience


Approximately 1/2 market
share of worldwide FPS’
Approximately 1/4 market
share of tankers



Marine & Offshore Consulting
1,200 staff in 50 offices worldwide
Numerous support services





Special studies (JIPs, RPs, etc.)
Recent Projects Related to Proposed JIP

In-service inspection planning

Risk based plans
 FPSOs (P-35, Zafiro Producer)
 Semis (Thunder Horse)
 Fixed platform fleets (BP West Java, Unocal Thailand)


Prescriptive plans (Holstein Spar, Neptune Spar)
Risk studies



Hull configuration risk (Su Tu Den FPSO)
Mooring configuration risk & reliability study (P-37,
P-43/48 FPSOs)
HAZID, HAZOPS & Reliability studies (CNG Carriers
and LNG & GTL FPSO concepts)
Motivation for Experience Database JIP



Limited operating experience to draw
upon when making decisions regarding
FPSO hull integrity
Typically draw upon tanker operating
experience for
 Corrosion rate estimates
 Construction detail performance
 Coating performance
FPSOs are not tankers
 No dry docking
 Cargo content vary
 Offloading frequencies are higher
 Site specific
Motivation for Experience Database JIP
Continued growth of FPSO fleet increases need
for a more complete set of experience based
operational data (across company lines)
 Past efforts to collect FPSO data generated
general information but not quantity or detail
required to



Assess current design and maintenance
practices
Develop firm foundation for implementation of
RBI or other inspection techniques
Central Theme: “Need for more FPSO specific
operating experience.”
Objectives of Experience Database JIP
Aggressively collect experienced based
operating data to evaluate influence of
FPSO/FSO specific operations on hull integrity
and determine implications on design and
while on site
 Evaluation of influence of FPSO specific
operations on structural integrity to enhance
decision making process related to FPSOs

Objectives of Experience Database JIP

Provide Guidance and Application Tools


Interface with participant FPSO data
owners
 Main groups
 Operating units

Clean up data



Remove relationship between data
and vessel/operator (i.e., ensure
operator anonymity)
Organize and categorize data
Identify erroneous and missing data
Evaluation & Deliverables

General Data Set Evaluation - “Lessons learned”





Trends
Alternative approaches used by different
operators for integrity management
Risk mitigation alternatives
Influence of operating conditions on hull
integrity
Numerical Data Set Evaluation (inspection
guidance)



Spatial zoning of corrosion
Confidence level for probabilistic corrosion rates
Effect of inspection on corrosion rate estimates
Evaluation & Deliverables
Identify areas where additional data collection is
warranted and provide recommendations on
collection methods and procedures
 Develop foundation for future application and
guidance on alternative inspection planning
techniques
