OTC15068: "Experience-Based Data for FPSO’s Structural Design." Authors: Ge Wang, Y.S. Shin, ABS; Robert Spong, ABS Consulting.

Increasing interest in FPSOs, coupled with a lack of systematic conceptual and preliminary designs, makes development of relevant design data both necessary and useful. This paper presents structural strength-related data for use in the structural designs or selection of designs for FPSOs. Experience-based data facilitates the development of rationalized approaches to decision-making and inspection.

TUESDAY, May 6, 2-4:30 p.m., Room No. 609.

OTC15215: "Crew Habitability on Offshore Installations." Authors: Denise McCafferty, Kevin McSweeney, ABS.

Human Factors Engineering classification guidance developed over the last two years is currently being field-tested on commercial vessels and offshore installations. New designs and refurbishments of older facilities are utilizing ABS Guides and classification standards to prevent marine accidents and casualties by reducing crew fatigue and improving human performance.

WEDNESDAY, May 7, 9:30-Noon, Room No. 604.

OTC15245: "Impacts of Vortex-Induced Motions on Mooring System Design for Spar-Based Installations." Authors: Ken Huang, Xiaohong Chen, ABS; Chi-Tat Kwan, Consultant.

This paper studies the impact of vortex-induced motions on spar mooring design. Advantages and disadvantages of mooring systems using spiral strand wire rope versus polyester rope are investigated in water depths ranging from 2000 feet to 6000 feet. The paper can assist engineers to design safe, reliable and cost-effective mooring systems for spar-based installations.

OTC15265: "Industry Trends for Design of Anchoring Systems of Deepwater Offshore Structures." Authors: A. Eltaher, K. Chang, Y.R. Rajapaksa, ABS.

This paper addresses geotechnical design of deepwater anchoring systems, issues encountered and future studies needed. As some deepwater anchoring systems do not have universally accepted design approaches, site-specific geological and geotechnical features are studied to identify foundation strength and deformation characteristics as well as geohazards that may affect risk and reliability evaluations.

WEDNESDAY, May 7, 2-4:30 p.m., Room No. 206.

OTC15298: "The Changing Regulatory Scheme Applicable to Offshore LNG Terminals." Authors: W. H. Daughdrill and C. A. Karpowicz, Ecology and Environment, Inc.; T. W. Grove, R. Gallagher, ABS.

This paper describes regulatory changes affecting offshore terminals importing liquefied natural gas (LNG). The paper proposes a process to combine current regulations with classification society guidance as a means of developing appropriate design, construction and operational requirements for offshore LNG terminals.

THURSDAY, May 8, 9:30-Noon, Room No. 305.

OTC15316: "Consideration of Collision and Contact Damage Risks in FPSO Structural Designs." Authors: Ge Wang, Dajiu Jiang and Yung Shin, ABS.

This paper presents a systematic approach to address the risk of collision and contact damage to FPSOs. Accident scenarios and associated occurrence frequency are determined through historical data, expert opinions and risk analysis.
