Thirdly,marine accidents during pilotage in the 2010s, such as oil spills in Yeosu of 1,003 thousand litres in January 2014, heated up the debate on pilotage and marine safety. The pilot and captain in the 2014 oil spill were arrested due to negligence not by the Pilotage Act, but by the Marine Environment Management Act. The Pilotage Act describes a pilot on board as an advisor or an information provider on navigation around a port (Park, 2018).
