OIM (Offshore Installation Manager)



OIM course is as per IMO (International Maritime Organisation) Resolution A.1079(28) adopted on 4th Dec 2013. This course is applicable for non propulsion vessel such as Construction, Pipe-lay and Accommodation barges; Semisub and Jackup drilling units etc which use anchor to stay in position.

This course is open to any mid level / higher level offshore rig worker. This Course is Approved by Liberia (LISCR) Flag State.

In addition, BCO course (MOU Stability) and at least IWCF Well Control Level 2 is required for OIM job.

The objective of this course is to enable prospective and incumbent MOU OIMs to practice and implement the actions and procedures required to safely manage a MOU under operating conditions. The course is programmed to represent a variety of operational and emergency situations e.g. in transit, ballasting, positioning, jacking and loss of control situations, for a mobile offshore bottom bearing, self elevated unit (Jack-up Rig). The course leads to assessment of competence to the standard required by IMO for OIM of an MOU.


1) Four years of service aboard MOUs including at least one year of service as driller, assistant driller, toolpusher, assistant toolpusher, barge 
supervisor, mechanical supervisor, electrician, crane operator, ballast control operator or equivalent supervisory position on MOUs.
