Abstract

Lõputöö eesmärgiks oli koostada tegevussoovitused Viking XPRS laevale elektriautode turvalise parkimise ala loomiseks, mis sisaldab peamisi tuleohutus ja -tõrjemeetodeid. Samuti oli eesmärgiks selgitada välja kõik riskid ja ohud, mida kujutavad endast elektri ja hübriidautod ja kuidas ennetada elektriautode tulekahjusid ro-ro ja ro-pax laevadel. Autor andis ülevaate tegevussoovitustest, mida võiks rakendada Viking XPRS ro-ro laeval. Üheks olulisemaks nendest on elektri- ja hübriidautode eraldamine tavasõidukitest ja nende märgistamine enne laeva sisenemist. Tuletõrjemeetoditena soovitas autor kasutada A-60 standardiga tuletõkisseina ning paigutada kaks vahugeneraatorit mõlemasse laevapardasse. Tulekahju ennetusmeetmena oleks vajalik paigaldada valve- ja soojuskaamerad elektriautode parkimisalale. Ennetamiseks ja efektiivseks ohu eemaldamiseks soovitab autor Viking Line’il investeerida erikoolitustesse ja võimaldada laevatöötajatele praktilisi regulaarseid harjutusi, mis on seotud elektriautode tulekahjude käsitlemisega. Antud uurimistööst selgus, et elektriautodega seotud tulekahjud on ohtlikud, nõuavad laevameeskonna suuremat väljaõpet ja on keerulisemad kustutada võrreldes tavasõidukitega. Elektriautode tulekahjud on ohtlikud, kuna eraldub palju mürgiseid gaase ja temperatuur muutub väga kõrgeks. Elektriautode kustutamine nõuab eriteadmisi ja -tehnikat elektriautode kõrgepingesüsteemide ja struktuurse eripära tõttu. Hetkeseisuga on paljude ro-ro ja ro-pax laevade meeskondade teadmised ja oskused puudulikud elektriautode efektiivseks kustutamiseks tulekahju korral ja ohutuks käitlemiseks

Abstract [en]

The aim of this graduation thesis Prevention of electrically powered vehicle fires on ro-ro ships is to examine the reasons why electrically powered vehicle catches fire and why it is so dangerous compared to regular car and how the ship industries need to adapt to new fire risks. The graduation thesis is composed of 6 chapters, each of them dealing with different aspect of problems. Chapter 1 is introductory and reviews the most common types of electrically powered vehicles. The chapter is subdivided into four parts. Part 1 describes battery electric car. Part 2 and 3 reviews hybrid electric car. Part 4 defines fuel cell vehicles. Chapter 2 examines Li-ion battery and SAE J2929 battery test and how to safely operate with damaged electric car. The chapter consists of 3 parts. Part 1 focuses on Li-ion and most common battery types used in car industries. Part 2 investigates most common Li-ion faults and thermal runaway. Part three reviews SAE J2929 safety test which uses many ways to abuse Li-ion battery and see how it fails. Part 3 describes Toyota factory safety measures to safely handle damaged Toyota Prius. Chapter 4 is introductory and reviews ro-ro and ro-pax ships. The chapter is subdivided into 4 parts. Part 1 explains the difference between ro-ro, ro-pax ships compared to tankers and cruise ships. Part 2 reviews fires that have happened on ro-ro ships. Part 3 describes the safety measurements according to SOLAS 2 which are used on ro-ro ships. Part 3 provides an overview what will happen when fire has been occurred on ro-ro ship and what parties are interested to investigate the fire. Part 4 focuses on estimated number of fires on the vehicle deck. Chapter 5 concentrates on possible improvements on ro-ro ships regarding its fire safety. The chapter is divided into 4 parts. Part 1 focuses on fire protection. Part 2 focuses on fire detection. Part 3 describes fire fighting and Part 4 reviews structural measures regarding electric cars safety onboard. Chapter 6 uses Reference ship Viking XPRS and how it can increase its fire safety transporting electric cars. Workshop created a special parking place for electric cars and added fire prevention and fire fighting measurements to plan.
