Zusammenfassung:	An apparatus and a method for sealing a propeller shaft (1) of a marine vessel are disclosed. The apparatus comprises: a shaft sealing device (2); and a lubrication device (3) which includes a lubricating oil circulation line (4) and a lubricating oil circulator (5) for guiding lubricating oil to and from the shaft sealing device (2). The lubricating oil circulation line (4) comprises: a connection line (7) which is fluidly connected to the lubricating oil circulation line (4) downstream of the lubricating oil circulator (5) and upstream of the shaft sealing device (2), and fluidly connected to a second portion of the lubricating oil circulation line (4) to selectively guide a portion of the lubricating oil flow past the shaft sealing device (2). At least one hydraulically operated pressure relief means (8) is configured to control the flow of lubricating oil in the connecting line (7). An objective of the present invention is to provide a simple apparatus and a simple method for sealing the propeller shaft of a marine vessel. 해양 선박의 프로펠러 샤프트(1)를 밀봉하기 위한 장치 및 방법이 제시된다. 장치는, 샤프트 밀봉 장치(2), 및 상기 샤프트 밀봉 장치(2)로 그리고 샤프트 밀봉 장치로부터 윤활유를 안내하기 위한 윤활유 순환 라인(4) 및 윤활유 순환기(5)를 포함하는 윤활 장치(3)를 포함한다. 윤활유 순환 라인(4)은, 윤활유 순환기(5)의 하류 및 샤프트 밀봉 장치(2)의 상류에서 윤활유 순환 라인(4)과 유체 연결 상태로 연결되고, 윤활유 유동의 일부를 샤프트 밀봉 장치(2)를 지나 선택적으로 안내하도록 윤활유 순환 라인(4)의 제2 부분과 유체 연결 상태로 연결되는 연결 라인(7)을 포함한다. 적어도 하나의 유압 작동식 압력 릴리프 수단(8)은 연결 라인(7)에서 윤활유의 유동을 제어하도록 구성된다.
