Stockholm Agreement Analysis for Ro-Ro Passenger Ships Navigating in the North European Waters and the Baltic Sea

This paper is an extension of work originally presented in 2019 EUROPEAN NAVIGATION CONFERENCE (ENC) [4]. The paper has described the important role of the Stockholm Agreement in safety of the Ro-Ro/Passenger ships in the north European waters. The present work describes the way in which we can improve the safety in strong chance of destruction of ship at sea. All results are generalized for a given group of ships. The specific construction of the RO-RO/ Passenger ships, being characterized by flat vehicle decks which are practically open, un-subdivided, and additional passenger accommodation space, with ramp fitted astern and in some cases in fore or side of the ship, giving access to cars, trucks and trailers, or specific trains which remain on board in their laden state, has resulted in international regulation requiring, amongst other things, strengthening the damage stability requirements for this type of ships. The more stringent damage stability criteria has been adopted on a regional basis by northern European countries as STOCKHOLM Agreement, in 1996. The paper concerns an analyze of damage stability calculations results in compliance with the STOCKHOLM Agreement, when the Ro-Ro/ Passenger ship is fully loaded, with maximum Deadweight (DWT) and maximum draught, or partly loaded, with reduced DWT, and occurs Minor or Major penetration of destroyed compartments.
