A self-propelled device 100, e.g. an unmanned aerial vehicle such as a drone, is used for inspecting a cylinder liner of an engine, e.g. of marine vessels or ships. The device 100 is insertable into a lower portion of a chamber 12 encircled by a circumferential wall 11 of a cylinder liner 10 via a hole 16, e.g. a scavenger port. The self-propulsion mechanism (102, Fig. 2) may comprise rotors for propelling the device up the chamber or may comprise suction cups or magnets. The device 100 comprises apparatus (104, Fig. 2) for determining information about one or more characteristics of the cylinder liner when located in the chamber. The device 100 may be remote controlled and may determine a radius or diameter of the liner or sleeve.
