... Abstract The present paper presents a framework for holistic optimization of monopile foundations for a full offshore windfarm. The framework has been developed in-house at Wood Thilsted Partners and has been used for design of several full-scale wind farms including Vineyard Wind, the first...

... Abstract Rate of Penetration (ROP) optimization has played a key role in the economic return and value of both onshore and offshore wells by decreasing drilling time thereby increasing the net present value (NPV) of the localized field. In this study, an Artificial Neural Network (ANN) model...

... Abstract A wave field in a wave basin inevitably has spatial variation due to the wave’s cylindrical propagation property. Therefore, we aimed to develop an optimization method for the control of wave-makers to produce a spatially uniform wave field in a specified test zone inside a wave basin...

... Abstract A new optimized hull form was proceeded based on a parent ship 60000 DWT bulk carrier. The goal of optimization is to obtain better resistance performance in the loading conditions of scantling draught and design draught. Firstly, the numerical simulation of the parent ship was carried...

.... The optimization routine based on RL by pixel data is tested on the 2D model, which is a vertical section of the SPE 10 model. It has been shown that RL can optimize waterflooding in a 2D compressible reservoir with the 2-phase flow (oil-water). The proposed optimization method is an iterative process...

The loading case calculation was carried out using a 20000t bulk carrier as an example, and an optimized solution was obtained, which proved the effectiveness of the algorithm. The results show that the method can effectively...

... Abstract Using open-source software Dakota, this paper describes the process of generating an optimal parametric hull shape for a generic containership. Selected design variables defined the ship’s hull, and the influence of these variables on calm water resistance was analyzed. Computations...
