A hedge is an investment position intended to offset potential losses or gains that may be incurred by a companion investment. In simple language, a hedge is used to. Tubular Strength Comparison of Offshore Jacket Structures Under API RP 2. A and ISO 1. 99. 02. Offshore platforms are only 6. Offshore Jacket platforms in Malaysia are designed using API RP2. A Working Stress Design WSD code. API WSD code has proved its effectiveness and has been in use for long time, but it needs to be changed into load and resistance factor design LRFD based code which is being followed by all building code agencies. In place of WSD, limit state design or LRFD has proved to be more rational as it considers probabilistic models. The reliability of Jacket platforms is maintained in API RP 2. Memeo Instant Backup Download Deutsch. A LRFD by setting target safety factor the same as that provided in WSD, which means structures designed as per LRFD code will have the same reliability as API RP 2. A WSD which has already provided safe structures and the best available practice for design. When adopting LRFD methodology, the appropriate load and resistance factors can be optimised through the process of calibration. Api Rp 2A Lrfd Pdf' title='Api Rp 2A Lrfd Pdf' />Knowledge of the strength equations in the different codes and the similarities and differences between them is useful for the calibration. The first step in the calibration process is the determination of reliability of structural tubular members of the Jacket designed as per existing practice of WSD and LRFD code. In this text, API RP 2. A WSD code and International Standard Organization ISO 1. LRFD based code are taken into consideration for the reliability analysis. The relevant strength equations of three codes are identified and compared, and the similarities and differences are determined for tubular members which are the main part of Jacket structures.
