Training of Crisis Mappers and Map Production from Multi-sensor Data: Vernazza Case Study (Cinque Terre National Park, Italy)

This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

Bowtie models as preventive models in maritime safety

Aquest treball ha sorgit d’una proposta del Dr. Rodrigo de Larrucea que ha acabat de publicar un llibre ambiciós sobre Seguretat Marítima. Com ell mateix diu, el tema “excedeix amb molt les potencialitats de l’autor”, així que en el meu cas això és més cert. Es pot aspirar, però, a fer una modesta contribució a l’estudi i difusió de la seguretat de la cultura marítima, que només apareix a les notícies quan tenen lloc desastres molt puntuals. En qualsevol cas, el professor em va proposar que em centrés en els Bowtie Models, models en corbatí, que integren l’arbre de causes y el de conseqüències (en anglès el Fault Tree Analysis, FTA, i l’Event Tree Analysis, ETA). Certament, existeixen altres metodologies i aproximacions (i en el seu llibre en presenta vàries, resumides), però per la seva senzillesa conceptual i possibilitat de generalització i integració dels resultats era una bona aposta. Així, després d’una fase de meditació i recopilació de informació, em vaig decidir a presentar un model en corbatí molt general on caben les principals causes d’accidents (factores ambientals, error humà i fallada mecànica), comptant també que pot existir una combinació de causes. De tota manera, a l’hora d’explotar aquest model existeix la gran dificultat de donar una probabilitat de ocurrència, un nombre entre 0 i 1, a cada branca. Normalment les probabilitats d’ocurrència són petites i degut a això difícils d’estimar. Cada accident és diferent, de grans catàstrofes n’hi ha poques, i cada accident ja és estudiat de manera exhaustiva (més exhaustiva quan més greu és). Un altre factor que dificulta l’estima de la probabilitat de fallada és l’evolució constant del món marítim, tant des del punt de vista tècnic, de formació, legal i fins i tot generacional doncs cada generació de marins és diferent. Els esforços estan doncs enfocats a augmentar la seguretat, encara que sempre amb un ull posat sobre els costs. Així, he presentat un model en corbatí pel seu valor didàctic i gràfic però sense entrar en detalls numèrics, que si s’escau ja aniré afinant i interioritzant en l’exercici de la professió. En aquest treball també he intentat no mantenir-me totalment al costat de la teoria (ja se sap que si tot es fa bé, tot surt perfecte, etc…) sinó presentar amb cert detall 2 casos ben coneguts d’accidents marítims: el petroler Exxon Valdez, el 1989 i el ferry Estonia en 1994, entre altres esmentats. Són casos ja una mica vells però que van contribuir a augmentar la cultura de la seguretat, fins a arribar al nivell del que gaudim actualment, al menys als països occidentals. Doncs la seguretat, com esmenta Rodrigo de Larrucea “és una actitud i mai és fortuïta; sempre és el resultat d’una voluntat decidida, un esforç sincer, una direcció intel·ligent i una execució acurada. Sens lloc a dubtes, sempre suposa la millor alternativa”. The work has been inspired in its initial aspects by the book of my tutor Jaime Rodrigo de Larrucea, that presents a state of the art of all the maritime aspects related to safety. Evidently, since it covers all the topics, it cannot deepen on every topic. It was my opportunity to deepen in the Bowtie Model but finally I have also covered a wide variety of topics. Later, when I began to study the topics, I realized that the people in the maritime world usually do not understand to a great extent statistics. Everybody is concerned about safety but few nautical students take a probabilistic approach to the accidents. For this it is extremely important to study the population that is going to be studied: in our case the SOLAS ships Also, during my time at Riga, I have been very concerned with the most diverse accidents, some of them studied during the courses at Barcelona. I have seen that it is difficult to model mathematically the accidents, since each one has different characteristics, angles, and surely there are not 2 equal. Finally, it was accorded that I should concentrate on the Bowtie Model, which is not very complex from a statistical point of view. It is simply a fault tree of events model and a tree of effects. I present some examples in this Chapter 2. The difficulty I point out is to try to estimate the probabilities of occurrence of events that are unusual. We concentrated at major accidents, those that may cause victims or heavy losses. Then, for the sake of generality, at Chapter 4, I have divided the causes in 4 great classes: Natural hazards, human factor, mechanical failure and attacks (piracy and terrorism). The last concern maybe should not be included beside the others since terrorism and piracy acts are not accidents, but since there is an important code dedicated to prevent security threats, ISPS, it is example of design of barriers to prevent an undesired event (although it gives mainly guidelines to follow by the States, Port Terminals and Shipping Companies). I have presented a detailed study of the tragedy of the Estonia, showing how a mechanical failure triggered the failure of the ferry, by its nature a delicate ship, but there were other factors such as poor maintenance and heavy seas. At the next Chapter, certain characteristics of error chains are analyzed. Finally, the conclusions are drawn, offering a pretty optimistic view of the safety (and security) culture at the Western World but that may not easily permeate the entire World, due to the associated costs

Limitation of Liability for Maritime Claims: Multiple Perspectives and Legal Implications

The thesis is an attempt to analyse the concept of limitation of liability for maritime claims with multiple legal and policy perspectives. In trying to analyse the issues related to limitation of liability, the thesis explores the historical background to the development of the concept of limitation of liability within both civil and common law. A synoptic overview on the development of international conventions pertaining to maritime claims has been presented. one particular issue that is highlighted, is the recent development of the case law on conduct barring limitation provision in the LLMC 1976 Convention which may to some extent show the policy consideration behind legal reasoning from a common law perspective. Further, the discussion encompasses a brief examination of the legal effects of the International Safety mechanism in particular, the role of designated person, concerning alter ego concept pertaining to the rule of attribution within a corporate structure. In addition, an introduction to the economic analysis of law has been presented in order to show how liability concept is examined by this particular discipline and in what ways such study contribute to the discussion on the effect of limitation of liability within the context of the thesis. The emphasis has been on the examination of justification of the proponents and antagonists on the limitation of liability for maritime claims

Experiences with a Commercial ECDIS

The integration of accurate positioning and electronic charts provides an extremely valuable tool to the mariner when navigating under hazardous conditions. This paper describes the experiences of two organizations in Canada who work under such conditions. On the St. Lawrence River, the Canadian Coast Guard is using the PINS 9000, a commercial ECDIS, for ice breaking chores with few, if any, other aids and has demonstrated operational savings. Marine Atlantic, Inc., uses the same system for ferry navigation into and out of Port aux Basques, Newfoundland, where it not only assists in meeting a tight schedule, but also enhances safety when operating in difficult conditions
