The extraction of oil and gas from deep water is one of the most important challenges of the oil and gas industry today. FPSO is one of the leading platforms for deep waters. This study discussed the performance of FPSO deck modules under loads exerted on the hull of the ship. Modeling of the studied module was executed by SACS software and the effect of support using neoprene in the function o...

This paper describes a system for landing a vertical take-off and landing vehicle on a moving deck using a monocular vision system and inertial measurement unit. Data from the vision system and IMU are used to compute an estimate of relative deck position, and a touchdown trajectory generator based on tau-guidance is used to compute a path to landing. A trajectory-following controller follows t...

1. THE OVERHAND SHUFFLE (~o The two most common methods of shuffling a deck of playing cards are the riffle shuffle and the overhand shuffle. The riffle shuffle is performed by splitting the deck into two halves and interlacing them. Aldous and Diaconis have shown in Ref. I that approximately 2 log N riffle shuffles suffices to randomize a deck (the meaning of this will be made more precise bel...

In order to study pressed pile test and ultimate bearing capacity character of large-diameter steel pipe pile, based on two high-piled wharfs of Zhanjiang Port, pressed pile test and numerical simulation of three large-diameter steel pipe piles are analyzed in this paper. Anchored pile method is used to pressed pile test, and the curves of Q-s and ultimate bearing capacity are attained. Then th...

in present research, 17 centrifuge tests have been conducted to study the effect of various parameters such as the number of piles, the distance between piles, gradation and thickness of the granular layer on the load-settlement behavior of a pile raft system. the results showed the importance of granular layer to reduce the settlement of non-connected pile raft system when the roles of piles a...

Pentachlorophenol (CASRN 87-86-5) is a wide spectrum biocide that has been used extensively, primarily as a fungicidal wood preservative, in the United States and elsewhere since the mid1930s. In 1987 the U.S. EPA restricted the use of pentachlorophenol to non-residential use, primarily to the treatment and preservation of utility poles and cross arms, railroad ties, wharf pilings, and laminate...

In recent years, determining bearing capacity of piles from in-situ testing data as a complement to static and dynamic analysis has been used by geotechnical engineers. In this paper, different approaches for estimating bearing capacity of piles from SPT data are studied and compared. A new method based on N value from SPT is presented. Data averaging, failure zone and plunging failure of pil...

This paper presents a comparison of numerical methods for the modelling of pile driving noise in the near field of the pile. The numerical models considered consist of (1) an axisymmetric time domain finite difference method (FDM), developed by the Centre for Marine Science and Technology in the Matlab programming language, and (2) an axisymmetric time domain finite element method (FEM), which ...
