Abstract: There are well-known specifics of ro-pax ferry shipping, such as the time factor as a consequence of keeping a regular timetable and the priority given to minimizing heeling, pitching, and rolling caused by maximum focus on passenger comfort and ro-ro cargo safety. It is also extremely important to control the ferry’s fuel consumption, being one of the most
important cost components. The aim of the article is to draw the attention of shipping company managers to the great potential that lies in the use of routine operational data, collected exclusively on board the ferries. It is worth noting that the research in this paper is based on standard office software packages rather than advanced statistical methods of data analysis, which are usually not accessible for shipping managers. Contrary to typical ocean-going vessels, there are a number of factors that need to be taken into consideration when analyzing ro-pax ferry fuel consumption. Moreover, these factors occur, in many cases, accidentally and, thus, they are difficult to observe on board the ferry without utilizing expensive and time-consuming methods.The possibility of fuel control is important not only for economic reasons but also due to air pollution caused by engine exhausts. The article presents an estimation of increased fuel consumption caused by the degradation of the hull silicone anti-fouling coating. The presented estimations of fuel consumption may be treated as the base for calculations of the economic effectiveness of ferries.The attempt to resolve the above-mentioned problem was made on the basis of research on a real ferry, which took place on the Świnoujście-Trelleborg line between 2007 and 2019.

Title: A simulation method to determine the safe operating conditions for designed sea-going ferries

Author/Authors: Stanisław Gucma, Jarosław Artyszuk, Rafał Gralak, Adam Kowalski

Place of publication: Scientific Journals of Maritime University of Szczecin

Year: 2018

Keywords: safe ferry operation conditions, ferry maneuvering simulation, sea ferries design, navigation safety, sea simulation

Abstract: The presented method for defining the conditions of safe operation of marine ferries in ferry terminals allows verification of shipowner ferry designs. In the first stage of this method, simulations are used to determine the allowable wind speed. The second stage comprises simulations of ferry berthing aimed at defining safe manoeuvring areas, the energy of berthing impact and propeller stream speeds at allowable wind speeds. The method was used in the design of a
228 m long hybrid ferry.

Title: The chosen safety aspects of maximum size vessels passing in the presence of pleasure crafts at the Świnoujście Port entrance area

Author/Authors: Adam Kowalski

Place of publication: Scientific Journals of Maritime University of Szczecin

Year: 2018

Keywords: safety of navigation, marine traffic engineering, harbour approach, pleasure crafts, maritime pilotage, port rules, yacht marina

Abstrakt: Approaches to the port are usually considered high traffic areas. Not only deep draft vessels pass through this limited manoeuvring space, but also intensive pleasure craft traffic, especially during the summer season. Crossing of both commercial ships and pleasure craft traffic may generate dangerous situations for navigation. The aim of the following article is to present solutions to the aforementioned safety problem. The article focuses on the navigation safety aspects at the Świnoujście seaport entrance. Currently, Świnoujście-Szczecin Port Regulations take only large ships into consideration while specifying the safety passing at this area, at the same time, belittling the presence of small crafts up to 20 m in length. In order to prove the need for change, one should first present the necessary research concerning the evaluation of the safety level of maximum sized ships navigating at the Świnoujście entrance area in the presence or absence of small pleasure crafts. The surveys were conducted on a group of pilots and captains possessing pilot exemption certificates. The research findings clearly show that the traffic of small crafts and large ships should be separated due to safety concerns. Thus, marine traffic engineering solution is suggested in order to eliminate the most plausible dangers

Year: 2017

Keywords: commercial ship operation, ship maneuvering practice, anchoring safety, ship documents, ship stability,
inland navigation of an ocean-going vessel, optimization of fuel costs

Abstract: The study is a captain’s guide, illustrated with examples and results of the author’s own thoughts, as a result of

constantly acquired knowledge and experience. Selected issues related to the operation of a commercial ship were presented. Being aware of the fact that, for obvious reasons, the publication does not cover all the knowledge that a captain should possesses, the following topics are discussed in this book: elementary principles of organizing the work of a captain on a ship; operational analysis of fuel consumption; control of stability calculations; specifics of pilot sea navigation on inland waterways; aspects related to ship anchoring; ship manoeuvres in extreme hydrometeorological conditions.

Title: Safety problems of anchoring in restricted areas in extreme hydrometeorological conditions

Author/Authors: Adam Kowalski

Place of publication: Scientific Journals of Maritime University of Szczecin

Year: 2016

Keywords: extreme hydrometeorological weather conditions, manoeuvring area, port regulations, restricted area, safe anchoring clause, slewing on anchor

Abstract: The aim of the following article is to analyse the lying of a vessel at anchor in extreme hydrometeorological conditions. As an example it describes the situation of the Panamax type bulk carrier anchoring in Prince Rupert harbour restricted area. The investigation takes into consideration the impact of strong wind on the safety of anchoring in sheltered waters. The presented calculations concern problems of slewing which result in changes of heading. The analysis also includes a description of the wind and current forces. The final part focuses on conclusions whose aim is to improve anchoring safety standards in areas managed by harbour authorities
