This report is regarding an electrical installation of an alarm system on a post fishing boat called Andromeda. The background of the installation was an earlier and inadequate alarm system that led to a motor failure. The ship was taken out of service and was sold to Björn Magndahl who rebuilt it to a yacht. The project was conducted partly by developing the existing systems, partly by documenting the work by means of electrical blue prints. Except the alarm systems, an installation of the frequency control unit for the bow thruster was installed. The installation was working fine and the outcome of the documentation was handed over in a form of a binder during the test drive of the systems and the assignment was approved.
