Rig Stacking
Rig stacking refers to the process of decommissioning and dismantling an 
offshore oil rig or platform once it is no longer in use. This process involves a 
variety of steps to ensure that the rig is safely and properly dismantled and 
disposed of in an environmentally responsible manner.
The first step in rig stacking is to remove all the equipment and materials that 
are still usable or have value, such as drilling and production equipment, 
electrical and mechanical systems, and structural components. These items are 
typically inspected and refurbished, if necessary, before being sold or reused 
elsewhere. Next, the rig is cleaned of any remaining debris and hazardous 
materials, such as oil and chemicals. This is typically done by specialist 
contractors who are trained in handling hazardous materials and following 
proper safety procedures.
A drilling rig can be stacked in

What is the importance of a 
proper stacking procedure?
There are several reasons why a thorough 
stacking procedure is important:
● Safety
● Environmental responsibility
● Financial considerations
● Legal requirements
Safety
Decommissioning and dismantling an offshore oil 
rig or platform involves working with heavy 
machinery, hazardous materials, and potentially 
unstable structures. A thorough stacking 
procedure is essential to ensure the safety of the 
workers involved in the process.
Environmental responsibility:
Oil rigs and platforms can contain a variety of 
hazardous materials, including oil, chemicals, and 
other contaminants. A thorough stacking 
procedure is necessary to ensure that these 
materials are properly cleaned up and disposed of 
in an environmentally responsible manner.
Financial considerations
The cost of decommissioning and dismantling an 
offshore rig or platform can be significant. A 
thorough stacking procedure can help minimize 
these costs by ensuring that all usable equipment 
and materials are properly identified and 
removed, and by minimizing the amount of waste 
that needs to be disposed of.
Legal requirements
There are often strict legal requirements governing the decommissioning and 
dismantling of offshore oil rigs and platforms, including environmental 
regulations and requirements for the handling and disposal of hazardous 
materials. A thorough stacking procedure is necessary to ensure that these 
requirements are met.
Overall, a thorough stacking procedure is important to ensure the safety of the 
workers involved, protect the environment, minimize costs, and comply with legal 
requirements.
