1 There have been several serious incidents related to deficient interlocking on drilling machinery and pipe-handling equipment. This notice outlines the actions that should be taken to prevent such incidents.
2 Remotely controlled movable equipment is often used to assist in pipe handling, drilling and related activities. However, while such equipment may eliminate certain types of incidents, it may also introduce new hazards.
3 Collisions may occur between equipment and personnel, between equipment and structures, or between different items of drill floor equipment. Dropped objects are a further hazard arising from collisions.
4 Owners and operators of drilling equipment should ensure that clear lines of responsibility are established for maintenance and inspection of drill floor equipment.
