Considering the stress cycles in the joints and members due to wave induced forces on offshore platforms, fatigue analysis is therefore one of the most important analyses in the offshore platforms design. Although most of the steel jacket type platforms are designed and located in areas with relatively high ratios of operational sea-states, for maximum environmental events, would have acceptabl...

The oil and gas industry has moved towards Load and Resistance Factor Design through API RP2A LRFD and the recently published international standard, ISO-19902, for design of fixed steel offshore structures. The ISO 19902 is intended to provide a harmonized design practice that offers a balanced structural fitness for the purpose, economy and safety. As part of an ongoing work, the reliability ...

This paper addresses a detailed analysis of the ice–structure interaction process phase-locked ice crushing (PLC) against offshore structures. Directly measured load, structure response data, and in situ observation from field measurements on Molikpaq lighthouse jacket platform were used study. summarizes new ductile damage-collapse (DDC) failure mechanism for PLC process. The DDC shows that is...

The intensive increase of global warming every year affects our world negatively and severely. use renewable energy sources has gained importance in reducing eliminating the effect warming. To this end, new technologies are being developed to facilitate these resources. One technological developments is floating wind turbine. In order evaluate respective environmental footprint systems, a life ...

This paper presents the modeling and simulation of offshore wind power platform for oil and gas companies. Wind energy has become the fastest growing renewable energy in the world and major gains in terms of energy generation are achievable when turbines are moved offshore. The objective of this project is to propose new design of an offshore wind power platform. Offshore wind turbine (OWT) is ...

BACKGROUND Offshore oil platform work is regarded as a stressful occupation, and occupational stress has been shown to be an important risk factor for mental illness. Little, however, is known about the main and interactive effects of occupational stress and coping styles on the mental health of Chinese offshore oil platform workers. AIMS To explore the association of mental health with occup...

Steel-structured jacket or template platforms have been extensively installed in Persian Gulf offshore oil & gas fields. For the jackets in the water depth range of 40 meters in this region, utilizing the self-upending concept has been investigated. It has been concluded that designing the light weight jackets, implementing the self-upending process for their installation operations, are econom...

Most of the offshore wind turbines (OWT) recently installed in Europe, China and North America are shallow water. However, unlocking full potential OWT lies deeper waters. Jacket substructures have presented themselves as a reliable foundation concept for transitional water depth. This study focuses on structural static dynamic analysis traditional jacket (with X K bracing) patented three-legge...
