DECOMMISSIONING
The pressure is on for the global
decommissioning sector to deliver a huge volume of projects
so it’s no surprise that it has taken a long time to take off. Unfortunately the downturn of 2012 has meant the adoption and knowledge share of alternative processes and equipment between peers has faltered. We are now seeing a major window of opportunity to help inform operators of how certain power solutions will help deliver innovation to minimise the larger decommissioning costs. At Aggreko, the mission is to help operators become more efficient. One of the biggest challenges offshore
production has faced over the years is finding a suitable, sustainable and cost-effective power source. Offshore oil & gas wells have shown to have a large amount of supply, but providing
enough energy to power the rig to ensure maximum economic recovery has presented a unique challenge due to the offshore location. For rigs that have relied on gas turbines for their lifetime the decommissioning phase brings new challenges as the gas will not be available. Te turbines, if they can run on diesel as well, will be inefficient and the opex associated with their maintenance will in many cases be prohibitive and crucially can balloon over time. Turbines are a case in point in relation to aged equipment and this is where rental can be the ideal solution. Operators can hire high-performance equipment, without the need to invest capital expenditure that won’t be able to deliver a viable pay-back. With Aggreko the cost
of decommissioning power can be fixed at the planning stage. Tis provides certainty to the operator and may even release cash to other areas of the operation. During peak extraction periods, turbines
will have played a key role in operating a lot of specialised, heavy equipment used to drill the oil. Power would have been demanded by the crane and hoisting system, large engines, pumps, electric motors, energy needs for employees on the rig to refine water, provide heating for cooking and processing waste – the list goes on. Over the years, these rigs have become their own mini cities but once this all stops the once efficient high capacity turbine solution becomes a drain on resources. To put it into perspective, let’s take a hypothetical example of load requirements
