Agenda

• What are dropped objects?• What causes dropped objects?• Through the supply chain• Examples• What can you do?• Resources

Lloyd’s Register Energy - Drilling

At home and at leisure

The top three causes of fatal accidents are…

falls from height…

being struck by moving vehicles…

and being struck by falling objects.

Lloyd’s Register Energy - Drilling

There are two types of dropped objects:

Static - any object that falls from its previous static position under its own weight.

Dynamic – any object that falls from its previous static position due to applied force from equipment/machinery or moving object.

What causes dropped objects?• Poor hazard and risk assessment• Inadequate design (not addressing dropped object

potential)• Poor behaviors (people walking by unsafe acts/conditions)• Inadequate or improper inspection, repair and maintenance• Redundant/neglected/homemade tools and equipment• Failed fixtures and fittings/corrosion/vibration• Inappropriate procedures/not following procedures• Inadequately stored/secured tools and equipment• Poor housekeeping• Environment (weather, sea motion)• Planning and operational miscalculations

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

• A bolt attaching the gripper head to the upper racking arm came loose and fell to the drill floor during a tripping operation

• All personnel were outside the danger area.

Causes:

1. Incorrect material in manufacture

2. Bolt had the incorrect part number

3. Faulty design - should not have been with welded head

4. New design bolt in 2000 - not changed out.

Design - Bolt fell from upper racking arm to drill floor – 3.5 lbs. x 82 ft.

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

• Bar holding skid rubber in place fell 100 ft. to cargo deck.

Manufacture - Bar fell 100 ft. to cargo deck

Causes:

1. Poor design

2. Poor manufacture

3. Poor maintenance.

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

Packaging - Unsuitably packaged equipment

Box shown without warning labels/markings of heavy contents

Causes:

1. Unsuitable packaging process

2. Failure to check loads prior to dispatch.

Hydraulic pump approximate weight 70 lbs was inside cardboard box

• Unsuitably packaged equipment transported to offshore destination

• Cardboard box weighed approximately 70 lbs.

• Contents fell out during transit.

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

• Hammer and chisel found on the top of container prior to lifting.

Transport - Items found on the top of container

Causes:

1. Carelessness of persons using tools

2. Failure to check loads prior to dispatch.

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

• Debris found in the forklift pockets.

Quayside - Debris found in the forklift pockets

Causes:

1. Poor storage facility

2. Failure to check loads prior to dispatch.

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

Transport by Sea - Item left on top of a unit

Causes:

1. Lack of awareness of maintenance staff

2. Failure to check loads prior to dispatch. 

• A temperature gauge used to check exhaust temperature was left on top of a unit

• The gauge weighed approximately 0.5 lbs.

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

• Air regulator fitted to wireline hoist.

• Not designed for use at height

• Securing dogs not engaged

• When energized, cover and internals (0.5 lbs.) blew off and fell 35 ft. to drill floor

• No injuries were sustained.

Installation / Commission - Item not designed for use at height

Cause:

1. Equipment unsuitable for use at height.

Dropped Objects Who’s Responsible

• During cleaning of the drill floor the grating over a drain hole was removed. The grating was bent and a sledge hammer was used to straighten it. While hitting the grating, the handle broke and the sledge hammer bounced over the edge of the floor landing on the cat walk. The area below was not fenced off however no personnel were in the vicinity.

Recommended actions:

1. Secure tools when there is a possibility of dropping to lower levels

2. Fence off areas below when working at height

3. Replace sledge hammer handles from wood to composite material.

Operations - Broken tool handle (15 lbs.) fell 25 ft.

Responsibilities Through the Supply Chain

Dropped Objects Who’s Responsible

• Hammer (1 lbs.) fell 100 ft. from work platform following maintenance operations.

• No personnel were working in the vicinity.

Maintenance / Repair - Hammer fell 100 ft.

Causes:

1. Insufficient Risk Assessment

2. No securing of tools at height.

Responsibilities Through the Supply Chain

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

Decommission / Dismantle - Spike fell 7 - 8 feet

• Spike, hidden inside scaffolding tube fell 7 - 8 feet to the deck narrowly missing Scaffolder.

Causes:

1. Insufficient Risk Assessment

2. No securing of tools at height

3. Bad habits.

Recommendations:

1. Cap tube ends

2. Secure tools at height.

Dropped Objects Who’s Responsible

Responsibilities Through the Supply Chain

• Diesel power pack being back loaded. Access door opened and fell off.

• Further investigation revealed door hinges had failed and were repaired with Ty-wraps.

Packing - Access Door fell off during backloading

Causes:

1. Poor maintenance and fabrication of containers

2. Poor standards of inspection prior to dispatch

3. Insufficient repair methods.

How can I personally prevent dropped objects? Implement a Dropped Objects program, if not already in place.

Actively support the Dropped Objects program. Take responsibility for my actions. Look after my colleagues. Maintain good housekeeping. Stop unsafe activities by using Stop Work Authority. Make observations and report incidents. Review and follow procedures. Recognize known hazards, and follow the controls in place. Consider dropped objects in all Toolbox Talks. Consider dropped objects in all JSAs. Check areas after all work is completed, even if work was permit

controlled. Participate in Hazard Hunts. Investigate all incidents, including and especially near misses. Secure all tools and equipment when working at height.
