Marine pilot occupational accidents during transfer to/from the ship are at the top of the agenda after several safety campaigns by IMPA and individual attemptsThere is multiple transfer method for the marine pilot, but a most common way is to use the pilot cutter. This paper aims to predict marine pilot occupational accidents before it occurs by using historical data. Since the problem depends on several variables, this paper develops a model by using the random forest method to predict marine pilot accidents before happening with the random forest method by using RStudio software

Maritime transportation is one of the most complicated and hazardous business fileds. Maritime accidents still occur despite several precautions since maritime is exposed to natural factors more than any other industries. In this harsh environment as a part of their job, marine pilots often embark/disembark to/ from vessels and confront life-endangering personal accidents. In the maritime field, several risk assessments are applied. However, all of them could not evaluate occupational accident risk for maritime pilot specifically. This paper performs specific risk analysis using the bow-tie method based on past accident records. This paper aims to qualify root causes and quantify root causes by importance level according to occurrence probability. As a result of analysis, occupational accident occurrence probability is found to be 14%, indicating that accident occurrence rate is significantly high. Hence, the probability of root causes triggering accidents and accident occurrence probability can be ascertained so that preventive measurements can be implemented. Besides theoretical achievement, this paper provides safety awareness to marine pilots, Marine Pilot Organizations, and ship crew who play a key role during marine pilots' transfer.

A person who intends to become a maritime pilot shall have sea experience as a master, pass the apprentice pilot test and pilot test, and obtain a license from the Minister of Oceans and Fisheries. In Korea, the government limits the number of pilot licenses, considering the demand for pilotage. An inherent problem exist in the apprentice pilot test system as it conducts a relative evaluation based on test scores without an absolute evaluation standard. The purpose of this study is to identify problems of the current pilot test system and to suggest ways to improve the pilot certification system. In this study, the history of amendments of the pilot certification system in the Pilotage Act was investigated, and implications were derived by examining international standards for pilot certification, and a survey was conducted on 77 incumbent pilots. Consequently, a plan to improve the domestic apprentice pilot test and a step-by-step implementation plan for pilot certification system improvement were presented. The results of this study are expected to be utilized not only for the development of the government policy on pilot certification and for related academic basic data.

Maritime pilots are always exposed to unpredictable risks present in the marine environment because they are boarding ships through pilot ladders or accommodation ladders at sea. Since the pilot plays an important role in securing the safety of a ship entering or departing from a port, an injury to the pilot substantially affects the overall safety of the ship. The purpose of this study is to analyze pilot injuries and predict accidents. For this purpose, pilot injury cases are analyzed and potential situations are identified through a survey. Pilot injuries are also predicted. The survey was analyzed using the IPA (Importance-Performance Analysis) methodology, and the binomial distribution and Poisson distribution were used to predict injury trends. As a result of the study, 316.8 nearmiss occurred per pilot injury, and if the current accident management system is maintained, the probability of pilot injury occurring within 3 months is 64.4%. Based on the research results, the need for a management system to prevent pilot injuries and reinforcement of maintenance and installation for pilot ladders was suggested.

Pilots are always exposed to unpredictable risks of the marine environment because they are boarding the ship through pilot ladders or gangways at sea. Since the pilot plays an important role in securing the safety of ships entering or departing from the port, the injury of the pilot greatly affects the overall safety of the ship. The purpose of this study is to analyze pilot incidents and predict accidents. For this purpose, the pilot injury accident cases are analyzed and potential situations are identified through a survey. And the pilot injury accident was predicted. The results can be used as basic data for prevention of pilot-related accidents.

An accident during pilotage may cause several problems such as crippling the harbour function, environmental disruption, loss of life. Since the pilot plays an important role in the safe operation of the port, securing their safety is directly connected to the vessel's safety coming into port in Korea. Pilotage service is offered on request without distinction of day and night. And traveling by helicopter and boarding/disembarking using a pilot ladder from and to a pilot boat have a high risk of falling into the sea. So, pilots can fall into the sea while boarding/disembarking from ship which can lead to serious injury by cardiac arrest. A number of pilots have died or severely injured due to fall from the pilot ladder during embarkation and disembarkation up to now. Current safety measures at embarkation and disembarkation required by pilotage act and IMO resolutions could not prevent all the pilot related accidents. Therefore, to prevent pilot accident during boarding/disembarking from ship, it is necessary to include safety training requirement for new pilots under the requirements for licensing of pilotage act. It is also necessary to compel pilots to take necessary personal protective equipment when they use a pilot ladder. In addition, the placement of emergency kit on pilot boats and first-aid training are required in order to deal with emergency situation promptly.

The ship without thrusters and special propulsion system is supported by the tug boats during berthing and unberthing. The orders to tug boats are made by a pilot. If the positions of ship, tug boats and port are displayed in 2D map, it will be helpful to pilots. In this research, a network-based pilot supporting system(NPSS) has been conceptually designed NPSS, necessary for safe and efficient pilot, has two main functions. One is the monitoring of the situation of berthing and unberthing. And the other is the automatic calculation of the tug forces considering environmental conditions. The NPSS is designed on the basis of network system around the harbor. The NPSS will be validated using ship-handling simulator in the future.

The purpose of this study was to propose appropriate requirements to obtain a pilot's license in order to improve the safety of pilotage related to a survey of experts involved with pilotage. The survey has been conducted by experts from stakeholders in various fields. To suggest requirements for the license, a hypothesis test has been conducted. It turns out that onboard experience with higher gross tonnage is eligible for pilot. Secondly, it is required to have onboard experience of more than one year as a captain, within 5 years from the date that the individual takes the pilot's written test, with 5 years onboard experience as a captain. Lastly, if personality and aptitude tests are added to the requirements to obtain a pilot's license, the safety of pilotage will increase rapidly.

A new course keeping controller for RIB(Rigid Inflatable Boat)-type USV(Unmanned Surface Vehicle) is developed using pilot's steering pattern. A pilot's simple steering pattern is found out from various course change tests. It is used to course keeping algorithm, suitable for large course change more than 60 degrees. To validate the course keeping controller, sea trial tests are conducted. From sea trial test, new course keeping controller shows good performance with less overshoot, maximum roll angle less than $20^{\circ}$, which makes it possible that fast course changes without slip motion of USV.
