Few studies have been conducted on the constructability or economic feasibility of the coupling of Pre-tensioned Spun High Strength Concrete (hereinafter PHC pile). For this reason, before applying it to actual construction sites, an analysis of constructability and economic feasibility is necessary. Therefore, this study aims to compare the welding method with the high-tension vertical bolt method. It is found that the use of the high-tension vertical bolt method can reduce expenses by 25 percent on average compared with the welding method.

Ship Repair

Ship repair has gained prominence as a service offered at the shipyards following a crisis in the shipbuilding industry, which has seen a fall in demand for new constructions, causing many companies in the sector to stall, especially shipyards. For a repair yard to be economically viable, in times of crisis, cost reduction is essential to make a sustainable business, so this comparative study aims to check the technical and economic feasibility of this change in the type of dry-docking. The present work deals with a comparative study between the use of the longitudinal slipway and the airbags for dry-docking and repair of river barges. The study sought to identify data from the vessels used for this project, to verify the average displacement of these vessels to analyze the airbags' carrying capacity, as well as the size of the winch to perform the dry-docking service. Since most repair yards use leased areas, the flexibility achieved with the use of airbags, as well as the reduced need for investments in the area, are benefits provided by using them. This work presented satisfactory results for the use of river barge docking airbags as a competitive alternative in repair services.

Due to heavy fuel dependence, the “renewable energy system” idea is an important issue in South Korea. The government of South Korea is endeavoring to convert its energy infrastructure into renewable energy generation. As such, numerous studies have evaluated the economic feasibility of various renewable energy sources in South Korea. This study differs from those studies as it is focused on a smaller scale in terms of self-supporting nanogrid and microgrid energy. The purpose of this study is to determine which type of grid is more economical. To conduct a comparative study on the economic feasibility of nanogrids and microgrids, three substations on Jeju Island were randomly selected. We then suggested two scenarios. The first scenario is <nanogrid>, which changes each substation into a nanogrid, and the second is <microgrid>, which connects the three nanogrids to share electricity. This study identifies the optimal combination of hybrid energy resources using HOMER (hybrid optimization model for electric renewables) software to change the substations into an self-supporting energy nanogrid or microgrid. According to the net present cost and cost of energy results for each scenario through HOMER simulations, the <nanogrid> scenario is more economical than the <microgrid> scenario. However, this study also shows that microgrids can be the better option, depending on the distance between nanogrids. Finally, implications and limitations are discussed in the last section of this paper.
