Drilling offshore requires debris removal operation to remove any debris or anomalies that have been highlighted or found during any previously remotely operated vehicle (ROV) operations or geophysical surveys for certain location before Rig approaches.

It is important to maintain any subsea structure and its premises clear from any debris that may affect any upcoming operation hence, the structure stability and safety regardless of water depth, which considered as one of the limiting factors.

Debris management is a major concern for all companies operate offshore rigs as offshore debris is responsible for many of the problems and much of the extra cost associated with extreme water depths. The offshore debris usually comes from trash, fishing gear, inadequate waste disposal and management, industrial activities, structure abrasion, construction and illegal dumping and other items lost off vessels or platforms at sea.

This paper discusses procedures and tool systems developed to optimize the efficiencies and economics of debris removal. Issues pertinent to water depths, debris size, shape will be discussed, with the problems associated with removal of debris caused by human activates, aged structure, inadequate waste disposal, etc. The authors will outline techniques and procedures for removal of this debris and discuss a tool system that is a workable solution for these problems. This paper will focus on the use of a Multipurpose debris lifter to remove debris from areas within platform vicinity that have normally proven very difficult. The system has been shown to be effective in removing debris from problem areas.
