But, besides un-doubted advantages, it gives rise to uncertainties and challenges in several aspects, which include those related to the fields of cybersecurity and legislation, in relation to international regulations and national laws. The aspects of autonomous shipping are included in the information regulations of Bureau Veritas, and additional specific tags have been created to collect the cybersecurity/cyberprotection aspects of such ships.</span></p> <p class="p1"><span class="s1">The objective of this article is to present the current status and the foreseeable evolution of the regulations on autonomous shipping from the point of view of a Classification Society, as well as the current evolution of the methodologies concerning cybersecurity.</span></p> 2019-07-31T00:00:00-05:00 Copyright (c) 2019 Cotecmar https://shipjournal.co/index.php/sst/article/view/186 Naval Architecture: From Theory to practice 2019-09-18T11:39:52-05:00 Richard Luco Salman rluco@uach.cl Rodrigo Flores Troncoso rflores@navtec.cl Rodrigo Baos Ortiz rbaos@navtec.cl <p class="p1"><span class="s1">The complexity of projecting and designing a ship requires a work sequence that covers at least three main areas: (1) Concept engineering; (2) Basic engineering; (3) Detail engineering. This paper explains the design transition that exists (or should exist) between concept engineering and the final product, emphasizing the existing contractual relationship with the shipbuilder, especially in the initial definition of the project and the influence on construction aspects.</span></p> 2019-07-31T00:00:00-05:00 Copyright (c) 2019 Cotecmar https://shipjournal.co/index.php/sst/article/view/187 Naval professional qualification in the Amazon state 2019-09-12T16:33:43-05:00 Nadja Vanessa Miranda Lins nvmlins@gmail.com Renato Carlevaris renatoc88@hotmail.com <p class="p1"><span class="s1">This article aims to report the efforts that have been made in the Amazon State for Naval professional qualification from 2007 up to now. And it is justified by the position of the Amazon State as one of largest Naval Brazilian Poles, so it is necessary to qualify professionals to meet the demands of construction, repair and maintenance of fluvial vessels in the shipyards. Partnerships with government institutes for education qualified shipbuilding technicians; and partnerships with private universities and other nongovernmental organizations sought to provide a new way of thinking for engineers and architects who were unaware of the naval market. The standards applied in the trainings and their respective focuses will be presented here. And the results will show the synergies created with other universities, the market, the shipyards and the professionals who were qualified.</span></p> 2019-07-31T00:00:00-05:00 Copyright (c) https://shipjournal.co/index.php/sst/article/view/188 Design and construction of a prototype for the launch and recovery of a “SAAB SEAEYE FALCON” ROV for the diving and salvage department of the Colombian Navy 2019-09-12T16:34:51-05:00 Jeison Rojas Rúa jeison.rojas.ru@armada.mil.co Héctor Ivan Sánchez Mateus hector.sanchez.ma@armada.mil.co Wilson Ovalle Porras wilson.ovalle@armada.mil.co Lissette Casadiego lissette.casadiego@armada.mil.co <p class="p1"><span class="s1">The divers of the Colombian Navy carry out search and salvage operations of equipment that are submerged in maritime or fluvial areas. To be effective, the diving and salvage department must have appropriate equipment to ensure the completion of the inspections carried out; however, since underwater dive inspections are carried out in difficult access or dangerous places, it is necessary to use specialized equipment such as remote operation vehicles - ROV, where the urgent need to implement a launching system for the immersion and subsequent extraction of such equipment is identified.</span></p> <p class="p2"><span class="s1">As a result of the existing problem, the project is built with the purpose of creating a prototype for the immersion and extraction of a “SAAB SEAEYE FALCON” ROV, thus facilitating inspections and reaching depths of 300 meters. For its construction, exploratory research was carried out and a deductive method was applied; modeling was performed using SolidWorks software as a tool for its construction that allowed identifying the best electromechanical structure, and the component to be used for its construction was identified through the study of pure and composite materials, which processes allowed designing and building a LARS prototype that met the operational objectives for which it was proposed.</span></p> 2019-07-31T00:00:00-05:00 Copyright (c) 2019 Cotecmar https://shipjournal.co/index.php/sst/article/view/189 Process of design an eco-friendly catamaran to extract aquatic plants 2019-09-18T13:32:24-05:00 Leonardo Abel Ponce Adriazola leonardo.ponce@utec.edu.pe José Luis Mantari jmantari@utec.edu.pe <div class="page" title="Page 1"> <div class="section"> <div class="layoutArea"> <div class="column"> <p>This paper presents the design of an eco-friendly catamaran that follows two design methodologies, one focusing in the importance in the needs of future users and the other the spiral boat design methodology. The project is going to take advantage of the unique form of a catamaran and use the space available between the points of flotation for the process of extracting small plants and light plastics from the surface of recreational lakes. With the project the esthetics and also the aquatic ecosystem of the lake would be better preserved. The application of the project, could improve the time required to recollect the duckweed and only required one operator; however, the potential of the project is significantly bigger as it could be used as a method to extract superficial contaminants in ‘garbage patches’ in the ocean and lakes without harming the species that still are in the zone of operation. Good practices of engineering are going to be use for the design of the catamaran, as well as for the selection of the necessary components.</p> </div> </div> </div> </div> 2019-07-31T00:00:00-05:00 Copyright (c) 2019 Cotecmar
