One of the main objectives of the present document is to develop a fast and stable plus reasonably accurate method of numerical simulation in order to revisit and predict the flooding scenarios. The author, Henrin Dankowski, has performed a good professional comparison with the results obtained in the course of the standard benchmark tests and repeated investigation of three accidents, namely the Estonia, the Heraklion and the European Gateway, for validation purpose.

The aim of the method presented in this volume was to fill the gap that exists there between relatively simple evaluations of ship stability and more complex and time consuming methods of simulation of the seakeeping. Subject method has been implemented in the software environment E4 specifically developed for ship design. Subject environment is providing users with the direct access to the complete vessel data model and to the computational algorithms that have already been implemented.

Calculations of the damage stability of a vessel at early stages of the design are considered essential indication of the vessel's safety level to withstanding the water ingress. Several accidents that have occurred in the past are demonstrating how important it is to consider the intermediate stages of flooding process and not only looking at the resulting final stage.

The present guidebook was prepared by the MarneInsight team to provide necessary technical guidance to ECA, i.e. Emission Control Areas, compliance for the ocean-going vessels. The content of the publication has been divided into six major chapters. The first chapter briefly introduces the Annex VI to the MARPOL Convention and explains what the ECAs are.

The second chapter explains in detail how exactly vessels produce the nitrogen oxide and sulfur oxide, i.e. NOx and SOx, emissions. The next chapter contains necessary precautions to be taken into consideration when you switch from HFO to LSFO, i.e. from heavy fuel oil to low-sulfur oil. This chapter is followed by the one providing all associated documentation, namely some important logs, record books and diesel engine technical files accompanying every engine installed on board. Finally, the sixth chapter of the booklet gives information about various methods that have been established to achieve compliance with the ECA requirements.

The information has been presented in a very understandable format making this book practical to everyone, but first of all, of course, it is aimed at the crew members and support personnel of the marine vessels directly involved in operation of the marine diesel engines and associated fuel oil supplies.
