Manufactured now by ASAMS, the SYSTEM 3 MPI is a modular design employing a sophisticated power control Surface Unit and an integrated, pressure compensated, Subsea Unit with built-in ink management systems. A heavy-duty isolating transformer supplies power to the Surface Unit, which is connected to the Subsea Unit via a single 200 metre umbilical, which is deployed from a strong hand operated spooling frame.

The Surface Unit is housed in a rugged stainless steel case with removable front cover. Its key features include: • An input-output current ammeter • Earth Leakage detectors and trips • A magnetising loop operation indicator • A demagnetising facility • Remote control of the magnetising current.  The Subsea Unit has AC and DC outlets for three magnetising techniques - Electromagnetic Yoke, Magnetising Coil and Prods. The Magnetising Coil and Prods can be AC or DC powered, whilst the Yoke is DC powered and allows bolt-on articulated sections to be fitted to enable inspection of irregular/awkward shaped work pieces. These three options allow the user to select the best tool for a particular structure or pipeline configuration, increasing operational flexibility and speeding up MPI diving programmes.

The Subsea Unit contains a 7KVA magnetising transformer, power/supply conditioning choke for the powerful UV lamp and a motor-driven ink circulation system which continuously agitates the magnetic particles. The top of the unit carries a 10 litre ink reservoir fitted with quick-release hoses to enable the diver to change the reservoir easily. The Powerful UV Lamp is connected to the Subsea Unit via a 6 metre combined power and ink delivery umbilical. A lever controlled ink nozzle on the lamp head allows one-handed operation
