{"title":"Mitigation of Infectious Disease Outbreaks: Considerations for the Marine and Offshore Industries","authors":"Martin Petricic, G. Burton, Libin Miao","doi":"10.5957/TOS-2021-16","DOIUrl":"https://doi.org/10.5957/TOS-2021-16","url":null,"abstract":"Similar to land-based facilities, marine and offshore assets can be exposed to outbreaks of infectious diseases. This is exemplified by the recent COVID-19 outbreak which has had a significant impact on both personnel health and normal operations of the assets. The occurrence and transmission of infectious diseases on marine and offshore assets can, however, be mitigated by appropriate physical arrangements on board and having operational procedures in place. This paper addresses the former. The effectiveness of operational measures can be significantly increased if infectious diseases are considered at the asset’s design stage. ABS has identified a lack of available technical guidance regarding physical arrangements that can help make marine and offshore assets safer for crews and reduce the spread of infectious diseases, such as COVID-19. This paper presents the best practices and recommendations for physical arrangements drawn mainly from the recognized standards for land-based medical facilities and applied to marine and offshore assets. The recommendations focus on specific spaces inside the accommodation block, their number, location, layout, ventilation, and interior surfaces. Isolation cabins with their associated anterooms are proposed as the most reliable way of isolating suspected or confirmed cases of an infectious disease from the rest of the personnel on board. Negative pressure, independent exhaust system, and easy to clean surfaces that are accessible and resistant to deterioration from frequent cleaning and disinfection are effective measures in containing the transmission of infectious diseases that are spread through the air or direct and indirect contact. The paper also emphasizes the need to promote segregation of the visitors from crew and passengers by providing designated spaces for the visitors and gives recommendations on the communication equipment needed for receiving medical advice from land-based medical specialists. If properly implemented and if augmented with robust operational measures, physical arrangement measures have the potential to significantly improve the safety of the crew, passengers, and visitors, as well as minimize the negative consequences of disruptions to normal asset operations.","PeriodicalId":212821,"journal":{"name":"Day 1 Tue, April 06, 2021","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115056050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Autonomous and Optimized Ship Routing","authors":"I. Emiris","doi":"10.5957/SOME-2021-017","DOIUrl":"https://doi.org/10.5957/SOME-2021-017","url":null,"abstract":"We present state-of-the-art computational methods which are instrumental in autonomous maritime operations, and optimization of routing, scheduling as well as loading. Our aim is to survey mature algorithmic approaches developed within the Lab of Geometric and Algebraic Algorithms, towards exploiting intelligence and automation in modern shipping and, in particular, in various aspects of routing. We showcase our advances in two main axes: (a) geometric computing for collision avoidance in complex environments, thus allowing for semi-autonomous and fully autonomous navigation, and (b) optimization for routing under time constraints of the carrier ship, time windows of availability at the ports of call, and capacity constraints of various compartments within a vessel.","PeriodicalId":212821,"journal":{"name":"Day 1 Tue, April 06, 2021","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130543256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
