Analysis of the impact of exemption from pilotage for 75m and 90m long vessels on the fairway Świnoujście-Szczecin

Gucma L., Łazuga K.

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

2019

Vol. 13, no. 3

627--631

The aim of the study is to analyze the impact of exemption from pilotage for 75m and 90m long vessels entering Szczecin on navigation safety on the waterway Świnoujście-Szczecin. Available sources concerning the influence of maritime pilotage on the safety of navigation have been analysed. Such data have been collected and made available only for the Danish Straits, the Great Barrier Reef Area of Australia, the Bosporus Straits and the Tokyo Bay. The study also included an analysis of economic effectiveness of pilotage exemption in this area.

Human error in pilotage operations

Pilotage operations require close interaction between human and machines. This complex sociotechnical system is necessary to safely and efficiently maneuver a vessel in constrained waters. A sociotechnical system consists of interdependent human- and technical variables that continuously must work together to be successful. This complexity is prone to errors, and statistics show that most these errors in the maritime domain are due to human components in the system (80 ? 85%). This explains the attention on research to reduce human errors. The current study deployed a systematic human error reduction and prediction approach (SHERPA) to shed light on error types and error remedies apparent in pilotage operations. Data was collected using interviews and observation. Hierarchical task analysis was performed and 55 tasks were analyzed using SHERPA. Findings suggests that communication and action omission errors are most prone to human errors in pilotage operations. Practical and theoretical implications of the results are discussed.
