If the oil content is less than 15 ppm, the OCM allows the water to be discharged overboard. If the oil content is higher than 15 ppm, the OCM will activate an alarm and move a three-way valve that, within a short period of time, will recirculate the overboard discharge water to a tank on the OWS suction side.

Protection kits can be installed and uninstalled from vehicles in the field using only basic tools. The A-kit is fitted on the production line and is the combination of a limited amount of armoring (in difficult-to-access areas of the vehicle), together with a significant amount of armour installation attachments and required support structures ...

Tanks may be sounded manually or with electronic or mechanical automated equipment. Manual sounding is undertaken with a sounding line- a rope with a weight on the end. Per the Code of Federal Regulations, most steel vessels with integral tanks are required to have sounding tubes and reinforcing plates under the tubes which the weight strikes ...
