The paper also provides information relating to in-service performance of offshore platforms and the consideration of important, non-operational, performance criteria including design for in service inspections and re-purposing of platforms. If applied competently, with the appropriate...

.... INTRODUCTION The Fatigue analysis and failure of marine structures are important issues. The method of treating fatigue behavior of tubular joints in offshore platforms was investigated (Graff et al., 1983). The prediction methods and steps of fatigue analysis were proposed for offshore platforms (Fang et al...

... Abstract The offshore platform is the core device for the development of offshore oil and gas resources. In order to reduce the accident, the risk management of offshore platforms is urgently necessary. In this paper, the life cycle of offshore platform is divided into 5 stages. Key risk lists...

... ABSTRACT The stability against capsizing in rough seas is one of the most fundamental requirements considered by naval architects. In this study, Markov process theory is used to simulate the large amplitude rolling motion of ships and offshore platforms with random characteristics and strong...

... new treatments to improve the quality of inter-grid VOF interpolation. The improved CLSVOF method is first tested on a free jet case with matching overset grids, and results are compared with those from the pure level-set method. The second test is on a simplified offshore platform in a hurricane wave...

... for safely installing a topside. The float-over installation allows the installation of tens of thousands of tonnes of topside safely from a jetty to a target offshore platform. Among the additional structures used for float-over installation, the deck support frame (DSF) to safely support the heavy topside...

... ABSTRACT The rogue wave is a huge wave that rarely generated by wave energy focusing. The rogue wave can cause critical damage to a ship and an offshore platform due to its great wave energy and its unpredictability. However, its kinematic and dynamic effect to ships and offshore platforms...

... ABSTRACT The current methods for measuring ocean surface waves include free-floating wave-buoys and radars located on offshore platforms. In this paper, an introduction is made to a new Light Detection and Ranging (LIDAR) scanning system. The system developed by Teledyne Optech...

... by the pile running. The affected depth can be divided into three areas: fully affected area, partly affected area, no affected area. Based on this, a method is proposed for predicting shaft friction during pile driving considering pile running. INTRODUCTION With the development of offshore platform, more...

... ABSTRACT The pile foundation of the offshore platform is mainly used to support the weight of the platform and the jacket, while resisting the environmental load effect on the platform. The design of the pile foundation plays a vital role in the safe operation of the platform. The wave force...

... ABSTRACT In this paper, the hydrodynamic coefficients of the truss-type legs of the jack-up offshore platform was studied through a 1:10 scale leg model. The existing methods, e.g. the instantaneous value method, the least square method, the trial and error method, were used to solve...
