Content available remote The Possibility of Application of Algorithms Indicating Maximum Paths in Directed Graphs for Modeling of the Evacuation Process
Lozowicka D. H.
TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

Vol. 4, no. 2
227--231
EN
In the introduction, ways of accounting geometrical, population, environment and procedure parameters in the computer evacuation simulating programs have been shown. In the part to follow the meth-od for graph theory based representation of the geometry of escape routes has been described. Besides, means of indicating the longest time of emergency evacuation is proposed using a modified Warshall’s algorithm to find the maximum weights in the directed graph. The use of the algorithm to indicate maximum escape routes makes it possible to verify the arrangement of escape routes in newly designed or existing ships.

When the wet granular materials lose their shear strength they flow like fluids. This phenome-non is called liquefaction. The liquefaction can be prevented by means of limiting the moisture content of cargo by introducing the safety margin. Cargoes, which may liquefy shall only be accepted for loading when the actual moisture content of the cargo is less than its Transportable Moisture Limit (TML). It has been recognized that in some cargoes, moisture can gravity drain towards the bottom of the hold. The resulting much wetter bottom layer may therefore be prone to liquefaction and provoke instability of the entire cargo. To prevent sliding and shifting of ore concentrates in storage a biodegradable materials are added to the ore. The polymer materials absorb water from the ore particle’s pores and the moisture content goes down. In consequence polymer materials may prevent drainage of the water from the ore particle’s pore.

Content available remote Dynamic Component of Ship’s Heeling Moment due to Sloshing vs. IMO IS-Code Recommendations
Krata P.

Vol. 4, no. 3
363--368
EN
The comparative study of the dynamic component of heeling moment due to sloshing in ships’ partly filled tanks is presented in the paper. The characteristics of heeling moment are obtained in the course of experimental tests and numerical simulations. The heeling moment is decomposed and the research is focused on the dynamic component resulting from liquid movement. The results of the research are compared to the computations performed in accordance with the IMO IS-Code recommendations. The need for amending of the intact ship stability assessment procedure is suggested.

Content available remote Assessment of ISPS Code Compliance at Ports Using Cognitive Maps
Celik M., Ilker-Topcu Y.

EN
International ship and port facility security (ISPS) Code was developed by the International Maritime Organization (IMO) as an execution framework to ensure high level of security measures applicable to ships and port facilities. Besides contributions of ISPS Code towards security improvement, additional bureaucracy (i.e. documentation, certification, training, expenses etc.) and serious shortfalls have appeared dur-ing implementation process. This paper explores the ISPS Code practice at ports based on cognitive mapping approach. The outcomes of this research can be proposed to international maritime authorities in order to enhance the existing concept and regulatory compliances of the ISPS Code in respect to industrial feedback.

Content available Modernization of Maritime DGPS in Poland
Dziewicki M.
TransNav : International Journal on Marine Navigation and Safety of Sea Transportation
|
2009

Vol. 3, no. 1
39--42
EN
Some new techniques and functionality adopted for modernization of national DGPS systems by maritime administrations in Europe are presented. Any solution adopted must meet international requirements: IMO standards and IALA e-NAV Committee recommendations. The results of DGPS Re-capitalization Meeting in Gdynia 2008 are presented. Modernization and re-engineering of maritime DGPS must take into account backward compatibility with existing onboard receivers as well as future trends towards e-Navigation. Operational and legal status of the Polish DGPS network is also mentioned in this context.

Content available remote 10 Things They Should Have Told You About ECDIS
Edmonds D.
TransNav : International Journal on Marine Navigation and Safety of Sea Transportation
|
2007
|
Vol. 1, no. 1
71--76
EN
The aim of this paper is to highlight some operational and system issues that are frequently en¬countered by navigators trying to get to grips with ECDIS. This information should also be beneficial to man¬agers and owners who are making decisions about which system and chart format to buy, and the priority that should be given to formal training ahead of a mandatory requirement.
