Risk-based structural integrity management for offshore jacket platforms

Seismic Vulnerability Assesment of Jacket Type Offshore Platforms

Most of oil and gas offshore platforms are located in the seismic regains. So, Seismic vulnerability evaluation of the offshore platforms is one of the most important and vital issues in the structural systems. In this study, jacket type offshore platforms are studied by incorporating the pushover analyses and nonlinear time history analyses, in such a way that, first some push over analyses ar...

Offshore Risk Based Corrosion Integrity Management a New Methodology

The management of corrosion and integrity for offshore applications has become more critical as deepwater exploration and production continues. There are many challenges ahead, the most important being that the scope for error is greatly reduced. Repair, retrofit or replacement all become that much more difficult and costly due to logistics. The importance of correct execution first time is the...

Structural System Reliability Framework For Fixed Offshore Platforms

The main objective of this project is to develop a generic framework which will set the basis for achieving more consistent system reliability assessments. The main steps involved in a system reliability assessment, together with the key technical and philosophical issues, will be identified and examined. Their interrelations and relative significance will be assessed in order to link them toge...

JIP: Structural System Reliability Framework For Fixed Offshore Platforms

Seismic Reliability Analysis of Offshore Fixed Platforms Using Incremental Dynamic Analysis

It is generally accepted that performance-based design has to be reliability-based. Seismic performance evaluation is based on nonlinear dynamics and reliability theory taking into account uncertainties during analysis. Considering the economic importance of jacket type offshore platforms, the present research aims to assess the seismic performance of offshore steel platforms. In this study, th...
