While primary focus of this program shall be on the derrick, this policy applies to all other equipment areas of the rig that are determined to pose a hazard of falling objects, such as tool rooms, cranes etc. This program applies to; Saudi Aramco D&WO, Contractor and Service Companies.
1. Responsibility
A. The Rig Operator Person In Charge (PIC) is responsible for ensuring that the inspection required by this requirement are entered into the rig’s applicable preventive maintenance system and that the instructions contained therein are complied with.
B. The Rig Operator PIC shall ensure that all temporary equipment arriving at rig location for use in situations where it may create a dropped object hazard that is not covered by the inspections required under this requirement is accounted for on a log sheet that is to be maintained by the Rig Operator PIC until such time as the temporary equipment is removed from the rig.
C. The Rig Operator PIC is responsible for maintaining the temporary equipment log, and ensuring that an inspection checklist is added to “DROPS” for as long as the temporary equipment is in use on the rig.
2. Procedure
A. Identify the Derrick zones. Divide the derrick into small manageable sections to help you define areas for identification. The number of zones shall depend on the size of derrick and the amount of equipment in the derrick. Typically five zones are used:
1) Zone1: Travelling Equipment 2) Zone 2: Crown Section
3) Zone 3: Monkey board to Crown 4) Zone 4: Rig Floor to Monkey Board
5) Zone 5: Lower Substructure and BOP deck.
B. Compile an Inventory of Equipment. The inventory listing process will require considerable effort and commitment from various personnel and could take some time depending on available resources. The time and effort spent compiling this list will greatly affect the success of the program. An accurate and detailed list is crucial and will benefit all involved. Record the information using a separate form for each zone identified. On the same form enter the fastening methods used on each item and any inspection detail that will aid the inspector in the inspection process.
C. Remove all non-essential equipment from the derrick.
D. Review derrick inventory and define each item as essential or essential. Each item deemed non-essential or redundant should be analyzed for any knock off effect if remove. This process should involve Rig management.

E. Once the items are removed from the derrick the inventory list should be modified to reflect the changes.
F. Periodic inspections of the different zones shall be scheduled. Once inspections are carried out, the necessary information should be entered into the Preventive Maintenance (PM) system to show compliance. All items in the inventory need to be accounted for and inspected. Any item found in a particular zone, not listed in the inventory needs to be noted, with reason for being in the derrick and expected duration. The rig foreman may periodically request that the list be changed to reflect changes in operational requirements.
Note: Rigs should make the derrick inspections a part of their current PM program.
1) Inspection Schedule
a. All derrick zones shall be inspected by rig personnel a minimum of once per month with inspection results recorded in the PM system.
b. An annual derrick inspection shall be conducted by a third party contractor. A record of the third party inspection shall be kept at the rig site until superseded by the next annual inspection.
2) Control of Temporary Equipment
a. A log sheet should be used to effectively control temporary equipment within the derrick, e.g.
hand tools used during maintenance or equipment taken up the derrick for operation such as wire line work. The old age adage of “what goes up must come down” is extremely relevant.
b. Any tool or equipment taken aloft should be logged in and signed off by the person carrying out the task as well as the Driller on duty. Once the tool or equipment is removed, it should be logged out in the same manner. This log sheet should be used to periodically check to see that all temporary items have been removed from aloft after use.
3) Covering other areas of the rig
Once “DROPS” has been implemented for the derrick, the same process should then be applied to other areas of the rig, starting with the more critical areas first. Other areas should include but not be limited to the following:
a. Cranes b. Jack Houses
c. Storerooms, tool rooms and paint lockers d. Shale Shaker areas
e. Welding Shack and surrounding areas f. Machinery Spaces

g. Underneath drilling substructures between Cantilever Beams on jack-ups, and around the moon pool areas on floaters.
h. Quarters Areas, both internal and external, including accommodation spaces, galleys, mess rooms, change rooms, laundry rooms, etc. To make the inspection process easier these other areas should be divided up and assigned to specific departments.
i. Other Areas as determined by the OIM/PIC.
