The invention relates to in-situ retrofit of a powertrain (2) of a vessel (1) provided with at least one propulsion powertrain configured to provide thrust to operate the vessel (1) in a predefined first operating mode, such as a designed speed, the present invention relates to a retrofit for a marine vessel (1) in a first mode of operation, and at least one powertrain (2) comprising a multi-cylinder two-stroke internal combustion piston engine (6), a propeller (10) and a shaft arrangement mechanically connecting the propeller (10) and the engine (6), the retrofit comprising configuring the powertrain (2) to provide thrust to operate the marine vessel (1) in a second mode of operation with less power demand than the first mode of operation, an existing combustion chamber component (200) comprising at least a cylinder liner (114), a cylinder head (116), a piston (112) and a piston rod (110) is removed from an engine (6) of at least one powertrain (2), and-a new combustion chamber component (200 ') is assembled to the engine (6) of the at least one powertrain (2), including a new cylinder liner (114') having a smaller aperture than the existing cylinder liner (114), configured to produce a higher specific power than the removed old combustion chamber component (200).

    本发明涉及船舶(1)的动力系(2)原位改造,该船舶(1)设置有至少一个推进动力系,该动力系被配置为提供推力以在预定义的第一操作模式(诸如设计速度)下操作船舶(1),并且该至少一个动力系(2)包括多缸二冲程内燃活塞发动机(6)、推进器(10)和机械地连接推进器(10)和发动机(6)的轴装置,该改造包括将动力系(2)配置为提供推力以在比第一操作模式更少的功率需求的第二操作模式下操作船舶(1),其中,从至少一个动力系(2)的发动机(6)移除至少包括缸套(114)、气缸盖(116)、活塞(112)和活塞杆(110)的现有燃烧室部件(200),并且‑新燃烧室部件(200’)被组装到至少一个动力系(2)的发动机(6),该新燃烧室部件(包括具有比现有气缸套筒(114)更小的孔径的新气缸套筒(114’))被配置为产生比移除的旧燃烧室部件(200)更高的比功率。
