RISRecent Research and Development Relating to Platform Requalification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent efforts on wave loads and their structural effects, ultimate and fatigue resistance, and structural reliability issues relating to requalification of jackets are reviewed. The emphasis is ...
A Practical Formulation for Evaluating Combined Fatigue Damage From High- and Low-Frequency Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on Gaussian load processes, a new formula suitable for evaluating the combined fatigue damage due to high- and low-frequency loads is derived. Then, by using of the Winterstein’s ...
Extreme Dynamic Structural Response Analysis of Catenary Moored Spar Wind Turbine in Harsh Environmental Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Proper performance of structures requires among other things that their failure probability is sufficiently small. This would imply design for survival in extreme conditions. The failure of a ...
FPSO-Shuttle Tanker Collision Risk Reduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To reduce the occurrence of tanker drive-off, and to reduce the probability of recovery failure should drive-off happen, are two basic principles to reduce FPSO and DP shuttle tanker collision ...
Residual Stress in an Autofrettaged Tube Taking Bauschinger Effect as a Function of the Prior Plastic Strain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Autofrettage is a practical method for increasing the elastic carrying capacity and the fatigue life of thick-walled cylinders such as cannon and high-pressure tubular reactor. Many analytical ...
Experimental and Numerical Prediction of Collapse of Flatbar Stiffeners in Aluminum Panels
Publisher: American Society of Civil Engineers
Abstract: Flatbar stiffeners are attractive in stiffened plates from a fabrication point of view. Flatbars are susceptible to torsional buckling and collapse. Current approaches to assess torsional buckling strength are uncertain. ...
Implications of Inspection Updating on System Fatigue Reliability of Offshore Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Offshore structures are considered as fail safe and inspections are carried out during their service lifetime to assess their actual condition. In this paper, the effect of inspection updating ...
Effects of Avoidance of Heavy Weather on the Wave-Induced Load on Ships
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with evaluating the effect of heavy weather avoidance on the long-term wave-induced loads on ships. Two hydrodynamic codes, VERES based on a 2D strip theory and WASIM ...
Structural Response to Sloshing Excitation in Membrane LNG Tank
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sloshing in LNG membrane tanks may cause large pressures on the tank structure. To keep the cargo at the required low temperature, the tank structure is covered with an insulation, which has ...
Wave- and Wind-Induced Dynamic Response of a Spar-Type Offshore Wind Turbine
Publisher: American Society of Civil Engineers
Abstract: This paper addresses coupled wave and wind-induced motions of spar-type 5-MW wind turbines in harsh and operational environmental conditions. Global dynamic motion responses have been analyzed by aero-hydro-servo-elastic ...
