Study: Understanding the systemic influences on maritime pilot decision-making

Already published for the first time in September 2020: Maritime piloting operations involve on-call work schedules that may lead to sleep loss and circadian misalignment. The study documented pilot work scheduling practices.

Case Study: A study conducted for Fremantle Ports on vessel interacting within the harbour.

Maritime pilots work in an irregular deployment system (rotation system) with unpredictable work assignments under high levels of physical and mental stress. Fatigue or chronic diseases, e.g. coronary heart disease, peptic ulcers or gastritis can occur as a consequence.

The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

The role of a Tug Master undertaking harbour towage activities is a very specific one. He/she has to, alone or in cooperation with other Tug Masters, assist a ship in a safe and efficient way using his/her tug to the best of its qualities. 

Required tug power and number of tugs needed in variable conditions of wind, current and waves isin most cases an assessment made by pilots based on their professional experience. However, assessments will raise questions by lawyers if something goes wrong. They will use tools to calculate what really is needed with respect to tug power and number of tugs. They have furthermore the advantage of time.

London Pilots (PLA) have issued an excellent quick reference guide for Pilot Transfer arrangements, which can be used for pilots as well as ship’s crews. Please take not of this document and if you can, try to incorporate it into your procedures.
