Brief Background ABS/ABS Consulting Motivation for Experience Database JIP Objectives of JIP Description of Tasks Cost & Schedule JIP Contact Information
ABS Bureau & ABS Consulting
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
Risk assessments (RBIs, QRAs, HAZOPs, etc.)
Advanced engineering Blast modeling & testing 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
Design Maintenance and inspection Operations
Objectives of Experience Database JIP
Provide Guidance and Application Tools Lessons learned Assessment tools In-service inspection tools

Experience Data Set
•Lessons learned
• Applicability of industry practices
• Tools and guidance on risk based inspection applications
Task 2 & 3 - Data Collection
Task 4 -Evaluation
Literature Review
ABS Tanker Database
ABS & Other Society Survey
Archives
Task 5 -Documentation
Data Collection
ABS internal data Survey data (FPSO/FSO & tankers) Condition assessment data Technology studies
JIP participant internal data Inspection data Cargo composition Operational profile Corrosion protection FPSO features Repair history
Data Collection & Data Recording
Collection methods Participant interviews Response to written queries 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
