This study analyzes the crosstalk effects caused by the geometry of holes in a cable tray in offshore plants. Using the analysis results, we determine the optimal hole geometry that can effectively reduce the tray weight under minimum crosstalk. It was previously shown that metal cable trays can reduce crosstalk among cables. However, the impact of hole geometry was not considered. This study demonstrates the impact of hole geometry on the crosstalk. In addition, an algorithm is proposed to determine the optimal geometry of holes in the cable tray. The simulation results validate the proposed algorithm and can be useful for the designers of cable trays with holes.

<p><em>Shipbuilding industry, having a great ripple effect on national economy, has been fostered by some countries as the national key industries. Korea also has supported shipbuilding industry as one of the industries politically fostered by the state. Accordingly, the shipbuilding industry of Korea has started to developed since 1970’s, reaching the world’s top position in 2000</em><em>’</em><em>s with reference to all the relevant indices.</em></p><p><em>However, after the global financial crisis in 2008, the shipbuilding industries of Korea focused on offshore plants, resulting in huge deficit and being outranked by China.</em></p><p><em>In this article, the past growing procedure of Korea’s shipbuilding industry was briefly reviewed, and the future plans for regaining the past glories as the shipbuilding power were sought.</em><em></em></p>

The arrangement design of ships and offshore plants is normally being made based on data of the past design and experts’ experiences. When performing the arrangement design, experts refer the past data and add additional requirements to the data for a new design based on their experiences. During this task, delay in design can occur due to the data missing or the absence of experts. In addition, most of ships and offshore plants are operated in the ocean environment so that spaces that can be filled with components for them are restricted. In this sense, there is a need to accumulate data regarding the past design, experts’ experiences, and design rules as a systematic structure. And a demand for optimization technique for the arrangement deign of ships and offshore plants are increasing. For this, an arrangement design framework for ships and offshore plants based on expert system and optimization technique is proposed in this study. And the proposed framework is applied to a problem with regard to the arrangement design of a small size submarine, and an FPSO topside. The results shows that the proposed framework can be used as a new tool for the arrangement design of ships and offshore plants.

Today, the Indian pharmaceuticals industry is recognised the world over due to the quality and cost-effectiveness of its products. At present, globally it is one of the fastest-growing industries and contributes 2.4 per cent value wise and 10 per cent volume wise globally. India alone accounts for 20 per cent of global exports in generics. In 2016, the Indian pharma industry exported USD16.89 billion and is expected to touch USD40 billion by 2020. The present generics market has immense potentiality for foreign direct investment (FDI) inflows, and worth USD14.53 billion of FDI inflows came in between April 2000 and December 2016. We have witnessed that Indian pharma companies go for joint ventures with multinational companies, make strategic alliances and co-promotions, contract research and manufacturing services, export, acquisitions and mergers, focus on new markets other than the USA and Europe, buy offshore plants and increase stakes in other companies. India is also becoming an attractive investment for the clinical trials market. The objective of this paper is to analyse the Indian pharmaceuticals industry—opportunity and threats, strategies of the Indian companies particularly after trade-related aspects of intellectual property rights (TRIPS).

Fault diagnosis of wind turbine systems is a challenging process, especially for offshore plants, and the search for solutions motivates the research discussed in this paper. In fact, these systems must have a high degree of reliability and availability to remain functional in specified operating conditions without needing expensive maintenance works. Especially for offshore plants, a clear conflict exists between ensuring a high degree of availability and reducing costly maintenance. Therefore, this paper presents viable fault detection and isolation techniques applied to a wind turbine system. The design of the so-called fault indicator relies on an estimate of the fault using data-driven methods and effective tools for managing partial knowledge of system dynamics, as well as noise and disturbance effects. In particular, the suggested data-driven strategies exploit fuzzy systems and neural networks that are used to determine nonlinear links between measurements and faults. The selected architectures are based on nonlinear autoregressive with exogenous input prototypes, which approximate dynamic relations with arbitrary accuracy. The designed fault diagnosis schemes were verified and validated using a high-fidelity simulator that describes the normal and faulty behavior of a realistic offshore wind turbine plant. Finally, by accounting for the uncertainty and disturbance in the wind turbine simulator, a hardware-in-the-loop test rig was used to assess the proposed methods for robustness and reliability. These aspects are fundamental when the developed fault diagnosis methods are applied to real offshore wind turbines.
