ASAMS System 3 Subsea Magnetic Particle Inspection

Description Features: Three magnetising techniques in one system Full surface control and monitoring facilities High intensity ultra-violet UV lamp De-magnetising facility Transformer isolated power supply Built-in earth leakage detectors Operates at any depth The ASAMS SYSTEM 3 subsea magnetic particle inspection system is a modular design employing a sophisticated power control Surface Unit and an integrated, pressure compensated, Subsea Unit with built-in ink management systems. The subsea magnetic particle inspection unit is equipped to provide magnetisation of the work by means of DC electromagnetic yoke, prods or loop 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.
