Ship’s Turning in the Navigational Practice

Kornacki J.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2011

Vol. 5, no. 2

261--267

The turning-basin is a special part of the port waters area. During every port's call ship need to be turned. The paper presents the analysis of the ship’s turning in the navigational practice. The paper is based on the practical experience.

Six in One or One in Six Variants. Electronic Navigational Charts for Open Sea, Coastal, Off-Shore, Harbour, Sea-River and Inland Navigation

Weintrit A.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2010

Vol. 4, no. 2

165--177

In the paper the author tries to explain problems connected with utilization of the GIS (Geographic Information System) technology and more sensitively speaking its waterborne implementation, ie. the ECDIS (Electronic Chart Display and Information System) technology and the electronic navigational charts (ENC) in the widely comprehended maritime (open sea, coastal and harbour) and inland navigation which the author does not limit exclusively to river-reservoirs only, but widens also for channels, navigable lakes and areas which can be defined generally as sea-river navigation areas. In the paper author presents the classification of the electronic navigational charts, primary functions and performance standards for electronic chart systems for open sea, coastal, off-shore, harbour, sea-river and inland navigation.

On the Control of CPP Ships by Steering During In-Harbour Ship-Handling

Yabuki H., Yoshimura Y.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2010

Vol. 4, no. 2

157--162

This paper describes the results of experimental and simulation studies that aimed at developing effective control methods for single-CPP single-rudder ships during the coasting manoeuvre and the stopping manoeuvre. In order to improve the manoeuvrability of CPP ships under coasting, the authors performed full-scale experiments and confirmed that CPP ships under coasting using the Minimum Ahead Pitch (MHP) of CPP are controllable by steering. A simulation study was also conducted to evaluate the ship-handling method during the stopping manoeuvre that applies a turning moment to the ship by the maximum rudder angle steering prior to the reversing operation of the CPP and it is confirmed that CPP ships can be controlled sufficiently by the proposed method.

Analysis of the Influence of Current on the Manoeuvres of the Turning of the Ship on the Ports Turning-Basins

Kornacki J.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2010

Vol. 4, no. 4

397--402

The paper presents the problem of the influence of current on ship during the manoeuvre of the turning and influence on this manoeuvre. The test of the different qualification of the influence of current on the manoeuvre of the turning of the ship was undertaken. The analysis of the influence of the current was conducted on this manoeuvre.
