Abstract
One of the goals of control systems in autonomous ships and unattended engine roomof a ship is the minimization of potential breakdowns, because there is no crew onboard to solvethese situations. This is especially important in IMO type three autonomous ships, i.e., remotecontrolled vessels with no crew onboard that are operated from land.For the correct control of an electrical installation, it is essential that connections for electricalmanoeuvres do not fail. These connections are the ones that connect different auxiliaryelectrical generators and various automation equipment. There are two main connections forelectrical manoeuvres: serial contact connection and parallel contact connection. In a shipengine room, we can find many serial and parallel connection contacts. Some of them areimportant to ensure correct operation. Others are essential for critical equipment, main engineor electric auxiliary. A suitable design of the electrical installation has to minimize the risk offailure but it also has to allow the early detection of problems and guarantee the continuity ofthe operation even if a failure takes place.In this work, several types of serial and parallel contact connections are proposed with the aimto ensure correct operation at different levels of the electrical systems in the engine room,preventing failures and allowing early alarms to detect potential future problems. For each type,serial and parallel, three different configurations are presented, each one more robust than theprevious one, depending on the requirements and criticality of the particular electrical systemto be controlled. The advantages and shortcomings of each configuration are presented anddiscussed.
