Navigational risk management with under-keel clearance consideration

Gucma L., Schoeneich M.

Journal of Polish Safety and Reliability Association

2011

Vol. 2, No. 1

109--114

The paper presents idea of the safety management system established for safety UKC (under-keel clearance) for ships entering to ports. System consists of three components which can be used for navigational risk management during decision making in port. Application of newly system was presented for example research which carried out by Marine Traffic Engineering team for Ystad port.

Analysis of the ships’ UKC by probabilistic model based on chosen real data in period 2005 till 2009

Schoeneich M.

Journal of Polish Safety and Reliability Association

2010

Vol. 1, No. 1

215--220

The paper is concerned with the analysis of under-keel clearance of ships based on real data from Szczecin Maritime Office. Using probabilistic method for UKC assessment give it possibility to create the distribution of under-keel clearance in several ship’s passages and in further step to determine the probability of ship’s grounding accident during the port approach. The results of using this type of model could be used in risk assessment of ships entering to the ports, therefore it is possible to used probabilistic model in Maritime Office employees’ everyday decision making practice. Research results present verification of probabilistic model, based on data from Vessel Traffic Service database and probability of touching the bottom during ships’ passages on Swinoujscie - Szczecin waterway. Moreover there are presented examples of these situations when entering to the port for analysed ships is not allowed according to the model.
