Offshore wind energy has become a major source, and various studies are underway to increase the economic feasibility of floating offshore turbines (FOWT). In this study, characteristics wave-induced motion combined wind-wave platform were analyzed reduce variability extraction. A user subroutine was developed, numerical analysis performed in connection with ANSYS-AQWA hydrodynamic program time...

Interactivity has become a major consideration in the development of a contemporary art practice that engages with the proliferation of computer based technologies.

In the background of the offshore wind turbine monitoring applications, we analyzed the characteristics of the offshore wind turbine monitor and gave the architecture of the offshore wind turbine monitor system. We designed the system model of blade wear and vibration in offshore wind turbine, and combined with energy efficient data aggregation algorithm based on the specific application to mon...

PROBLEM Tragic marine and offshore accidents have caused serious consequences including loss of lives, loss of property, and damage of the environment. METHOD A proactive, risk-based "goal setting" regime is introduced to the marine and offshore industries to increase the level of safety. DISCUSSION To maximize marine and offshore safety, risks need to be modeled and safety-based decisions ...

One of the problems in construction work offshore derick flare stack is difficulty lifting and installing steel structure installation due to limited length boom crane arm. This study aims provide an overview working methods overcome these difficulties. The method handling problem dividing structural components segmentally, segments with roller-based aids ropes. results showed that was proven b...

The need of realistic models to evaluate the availability of multi-state, multi-output plants is felt in many advanced industries such as the nuclear, aerospace, oil and chemical ones. Indeed, often the complexity of the plant and of its maintenance and recon guration policies is such to render unfeasible its reliability/availibility evaluation by analytical models. In this paper we consider th...

The User Account Management System (UAMS) is an extension of the original User DataBase (UDB) system presented at the USENIX Large Installation System Administration Conference in 1990. This paper describes the extensions of the UDB system from a single administrative entity tool for a distributed set of computers to a multidepartmental system over the period of three years since the first pape...

A recent audit of oil and gas (O&G) production and process facilities (P&PFs) functioning on the Norwegian Continental Shelf (NCS) revealed that inadequate classification of equipment tends to increase the probability of maintenance induced failures. Hence, to mitigate the problem, this manuscript suggests a fuzzy inference system (FIS) to further revise and fine-tune an existing static mechani...

During the last decade offshore wind industry grew ceaselessly and engineering challenges continuously arose in that area. Installation of foundation piles, known as monopiles, is one most critical phases construction farms. Prior to installation a drivability study performed, by means pile driving models. Since latter have been developed for small-diameter their applicability analysis large-di...
