Economically preserve rigs and vessels during hot and cold lay-ups

Aggreko's specialist power, heating and drying solutions enable cost-effective preservation of important assets during hot or cold lay-ups. With a local presence near all major ports, our experienced engineers provide a rapid and responsive service 24/7, 365 days a year.

We can help:

  • Protect critical components of your capital assets 
  • Significantly reduce rig or vessel operating costs whilst idle 
  • Lower recommissioning costs and reduce reactivation timescales

Cold lay-up support

Utilising temporary power generators and specialist heating and drying solutions, we ensure a rig or vessel's equipment is kept in optimum condition.

Dehumidification units and associated distribution trunking can be installed to achieve sufficient air circulation, both in ‘controlled’ spaces and throughout major machinery, equipment and systems.

Aggreko's environmental control solutions help prevent deterioration of the structure and onboard machinery, and reduce the timescales and costs of reactivation.

Hot lay-up solutions

Aggreko's portable diesel generators offer a cost-effective solution to on-board power whilst a ship or rig is laid-up.

Our generators (20 kVA - 2100 kVA) can be quickly stepped up or down, depending on demand, to provide power for regular onboard maintenance operations, staff welfare facilities and the recommissioning process.

With our generators replacing the need to operate the main engines and emergency generators, we can reduce maintenance requirements and operating costs.


  • Global reach - consistent capabilities worldwide with bespoke solutions to match local requirements.
  • Turnkey service - from design to installation, service, maintenance and fuel management.
  • Cost-effective solutions - detailed on-site scoping study determines most efficient solution from our extensive product range. 
  • Specialist team - dedicated application specialists, process, mechanical, electrical and chemical engineers.
  • Experts in our field - we focus solely on power and temperature control solutions. This gives us the technical expertise, equipment, skills and experience on a scale, and to a depth, that no one else can rival.     

Our service

Aggreko's team of power and temperature control experts will perform an on-site scoping survey of each individual rig or vessel.

This ensures we understand the project's requirements and allows us to provide a detailed recommendation based on its specific needs.

The scoping survey will:

  • Determine the target areas where temperature control is required
  • Outline the ideal heating or drying system design
  • Identify power requirements
  • Provide initial cost estimates

Once a solution is agreed, our certified technicians will install and commission the equipment, following strict safety regulations for both off-shore and port requirements.

Our service is fully inclusive of all ancillary equipment, spares, servicing and maintenance. This allows total budget certainty and minimum hassle.  

We can also provide a reliable fuel management service, ensuring continuous equipment operation with minimal disruption.

Throughout the hire our specialist team is available to provide expertise in all aspects of the project - 24/7, 365 days a year.

Key applications

Auxiliary and back-up power    

  • Generators (20 KVA - 2100 kVA) at 50 Hz / 60 Hz to provide auxiliary power, onboard reserve power or emergency power for all rig and vessel requirements.
  • Temporary portside diesel generators to offer a 'cleaner' fuel alternative to onboard heavy fuel oil generators whilst in port.
  • Additional power for essential heavy lifting equipment.

Load testing

  • Resistive and reactive loadbanks to test a power supply system's functionality during repair and mobilization.
  • Simulation of adverse environmental conditions (from sub-zero to hot desert) for equipment performance testing.
  • FPSO (Floating, Production, Storage and Offloading) vessel load testing to ensure generators are properly calibrated and installed.

Temperature Control

  • Controlled dehumidification of internal air spaces (including void spaces within machinery and pipelines) to prevent sweating and humidity corrosion damage, as well as moisture absorption into electrical cables and fittings.
  • Maintaining stable temperatures in key areas to avoid condensation and prevent freezing.
  • Upscaling of equipment to various parts of the rig or vessel during seasonal ambient temperature changes.
  • Temperature control equipment to maintain a ship's HVAC system in dry docks.
  • Chilled water for a vessel's operating systems whilst in port.
