Consisting of a Robust Design Concept which is lightweight and portable (incorporating battery charger with backup battery), the MPGU is a very flexible unit and can be used in a variety of environments such as beach manholes and on board barges or vessels of opportunity. In repair scenarios, the MPGU can be used with various Subsea and Beach Joint Technologies.
