The AJ70 is a three legged accommodation & services jack-up which is part of the well-established GustoMSC AJ series. The series consists of distinct types for moderate and harsh environment designs. The AJ70 is the largest unit in the series and is driving the boundaries of jack-up territory further out. The AJ70 is specifically designed for all year use in water depths up to 150 meter on the Norwegian Continental Shelf in the North Sea, taking into account all Norwegian regulatory requirements regarding safety and working environment. It provides competition in an area previously dominated by floaters, but does that with much better uptime during the harsh winter months and with significantly less motion due to the fixed nature of a jack-up.

The AJ series further consists of the AJ46, AJ50, AJ54 & AJ62.
