DROPS Program

(Dropped Objects Prevention Scheme)

Over the years within the industry, it has been recognized that there has been

a high number of incidents of dropped / falling objects within drilling

derrick structures. The potential for this type of incident to severely injure

personnel or cause material damage on the drill floor and in the surroundingarea is very high.

Objective

Petrosantander omania is intended as a guide to eliminating the

incidence of dropped objects from within drilling derrick structures.

!s such, the overall objectives of the "OP# model are$

%liminate injury to people.

%liminate the incidence of damage sustained in the derrick

structure.

%liminate damage to other associated derrick e&uipment.

Strategy

OVERALL

The "OP# model, if followed closely, will reduce the number of

dropped objects from within the drilling derrick structures. The

principal actions re&uired to successfully adopt the "OP# model,include$

'. (orm a joint worgro!p with the crews and sites involved, with

identified (ocal Points from each team at those rig sites.

). *dentify the common prob"em areas.

+. "evelop an action p"an.

. -arry out and monitor the action plan.

#OR$%RO&P

The "ropped Objects orkgroup should be formed comprising, as a

minimum, the following persons$

!n identified -hairman such as a #enior anager 0to give the

workgroup support and management commitment1. *dentified (ocal Point from each location / site within the relevant

operator or drilling contractor rig2site team, i.e. ig #upervisor or

"rilling %ngineer.

e&uipment manufacturers and suppliers.

The orkgroup should identify areas or zones which have the potential

to create a dropped object incident 0initially the derrick will be

identified as the area of the greatest hazard, as your program matures

other areas will be included4 cranes, accommodation1 these can be

arrived at by analysing historical data such as incident reports, near

miss reports, location drilling reports, reviewing operational procedures

and data from Planned aintenance #ystems. The identified problem

areas can be used to form the basis of a remedial action plan.

areas. The following !ction Plan is to be used as a model and adapted

where necessary.

Step 01 Awareness ampaign

aise the awareness of and alert everyone as to the nature of the

problem and the actual and potential conse&uences of dropped

objects from within drilling derricks. This may be achieved by

reviewing country specific incident reports for this type of event

and highlighting the problem, utilising a poster campaign,

-onversations should be held with individuals and teams to raise

awareness of the problems and its conse&uences and what has to bedone to eliminate the problems.

"ivide the derrick into small manageable sections to help you defineareas. There are no rules to determine these areas or the number of

zones, however it should be logical and it may be helpful to select

obvious physical boundaries to ensure areas are clearly understood and

no e&uipment is overlooked from your analysis and inspection.

*ncluded in your presentation pack is an actual "OP# survey

completed here in #audi !rabia, this gives a different option as to howto sort the derrick zones.

*dentify the "errick 9ones. "ivide the derrick into smallmanageable sections to help you define areas for identification. The

number of zones will depend on the size of derrick and the amount

of e&uipment in the derrick. Typically five zones are used.

re&uire 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. !n accurate and detailed list is crucial and will benefit allinvolved. ecord 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 theinspection process.

non2essential. %ach item deemed non2essential or redundant

should be analyzed for any knock off effect if removed. This

process should involve ig management. Once the items are removed from the derrick the inventory list

should be modified to reflect the changes Periodic inspections of the different zones will be scheduled.

Once inspections are carried out, the necessary information

should be entered into the P system to show compliance. !llitems in the inventory need to be accounted for and inspected.

needs to be noted, with reason for being in the derrick and

reviewed to ensure that all current anufacturer maintenancerecommendations have been incorporated into the system. This

thorough process needs to be undertaken to ensure that thee&uipment being used in the derrick structure is as per design. *t

will also ensure that any modifications or changes to e&uipment

and its maintenance re&uirements is per the anufacturerBs latest

recommendations.

Step 91 A!tomated < ;echanised Derric Systems

The principles as described in this presentation for preventing dropped

objects do not change in the automated environments of remote

controlled drilling systems. 3owever, stringent inspection routines and

familiarity with the proper use of automated systems must be

maintained at all times. "ropped objects as a result of collision can be

avoided by making sure that in the design phase, the !nti2collision

#ystem and ig emote -ontrol #ystem form the basis for the !nti2

clash and coordination, which should be designed to prevent

interference between hoisting and drill floor/derrick e&uipment. The

method used mostly is to identify the zones and spatial corridors whichmore than one piece of e&uipment can occupy. 9oning depends on

e&uipment installed in the derrick and on the rig floor, taking into

The main cause of dropped objects in the drilling industry has been

winch operations.

The principle of reducing the incident is based on the fact that the

winch is designed / installed and maintained properly. The

operation of the winch is such that the people are knowledgeable

of the system, are trained and operate the winch within the design

criteria.

*n order to keep the "OP# scheme live, the system needs to be

updated whenever changes are made to the derrick inventory or the

structure itself.

To keep the focus and management attention to this problem, you

should regularly use and review the "errick *nspection eport, asdescribed under #tep +.
