As an answer to that, Totem Plus have developed the PPVR, which stands for pollution Prevention Video Recording System. The PPVR comes with several video cameras, located over pollution sensitive areas in the machinery spaces, together with a PC computer (located on bridge) that records the video data for up to one year data. The crew has no access to the data which is protected by the system, and the online monitoring is done from the bridge or Captain’s cabin PC. Motion detection algorithms are applied to the video frames, and the system will on such motion or on loosing connection to the cameras. Consequently, the bridge will be informed on any engineer going to these areas, or trying yo disconnect the camera of this area. 

Keeping history for one year allows replay of past incidents, in fast forward is necessary. Each frame recorded has a specific time stamp, showing date & time (UTC), ship name and camera number. The recorded data can demonstrate to authorities (e.g. USGC) that the ship’s personnel have not compromised or by – passed the pollution prevention equipment, and that the owners are keen on preventing such occurrences.
