Aggreko launches specialist service to reduce cost of idle assets in oil and gas industry

Aggreko has launched a specialist hot and cold stacking rental service to reduce operating costs and preserve rigs and shipping vessels that are laid up in docks or at sea.

The company is seeing growing demand for its heating, dehumidification and refrigeration services from rig and vessel owners wishing to protect critical structures and machinery and save money in readiness for better market conditions.

Russell Brown, Oil and Gas Industry Expert at Aggreko said, “Whether hot or cold stacked, it is important for on-board assets to be kept in optimum condition so they can be redeployed in future with minimum cost. 

“A simple answer is to install on-board temperature control equipment to prevent corrosion, condensation and freezing caused by unwanted moisture and salt from costal and ‘at sea’ conditions. This equipment creates a stable environment that ensures assets remain in peak condition, no matter how long it takes before they are re-commissioned”.

Using a variety of heating and dehumidification equipment, Aggreko controls the temperature and humidity of internal environments. This ensures void air spaces within machinery and pipelines remain dry and prevents corrosion damage and moisture absorption into electrical cables and fittings. Critical assets, such as the engine room, bridge and sensitive electronic equipment are protected.

Rental solutions offer customers flexibility in a number of ways. As a global provider with a presence near most ports, Aggreko has the logistical ability to change equipment, dependent on climate, if vessels are being moved around the globe or are docked in places where there are seasonal variances.

Brown explained: “temperature control equipment will perform to varying levels of effectiveness depending on the geographical or seasonal climate and consequential ambient temperature and relative humidity in which they operate.  We often deploy desiccant dehumidifiers and heaters in colder climates, and refrigeration equipment and chillers in warmer regions. Working with a rental expert will ensure the best solution is found”. 

Rental solutions offer customers the flexibility to upscale and downscale their temperature control equipment as their needs change.  Brown continued: “As a vessel comes back online or the environmental conditions change, the heating and dehumidification needs onboard may also need to change. A rental company will simply re-survey the needs of the site and amend the solution to meet the new requirements”.

As laid-up vessels also require varying degrees of power, Aggreko is increasingly supporting both vessels and dockyards with onboard or dockside power requirements.

Brown said: “By using correctly sized portable diesel generators for residual power, customers can reduce costs by shutting down main engines. They can also avoid using existing over-sized and consequently inefficient emergency generators. This saves money and effort on maintaining and servicing engines and back-up generation equipment”.

Rental generators can be scaled up or down with very short lead times to supply variable power requirements. This might include sufficient power for routine regular maintenance tasks, heating and lighting for the remaining crew, or larger load requirements, such as heavy lifting equipment. This ensures that rigs and vessels can be speedily remobilised to tight deadlines.

In addition, as part of the remobilisation process, customers can rent Aggreko loadbanks to load test generators and HVAC equipment and ensure that systems are functioning properly.

Brown said: “Renting generators removes the servicing and maintenance risk and cost burden from customers. The fixed cost model is fully inclusive of all ancillary equipment, spares, servicing and maintenance. As such, customers can budget accurately, with no hidden costs.

“As our power and temperature control equipment can be hired on a long or short-term basis, with the optimum flexibility, it’s the most cost effective way of preserving and powering assets until a time when the rig or vessel can return to service, refurbishment or resale”.
