3 ways to ensure laid up rigs and vessels are ready for remobilisation

The downturn in the oil and gas market has seen many vessels and rigs being laid-up in docks or at sea. How can vessel owners and managers ensure critical assets are preserved whilst they are laying idle? And how can they ensure cost-effective remobilisation when the time comes?
In his latest blog, Russell Brown discusses the three ways in which rental solutions can support hot and cold stacking, with minimal capital outlay.

1. Deploy environmental control equipment to preserve your assets

Whilst vessels are laid-up, it is important for owners to keep their on-board assets in optimum condition, so they can be redeployed in future without excessive cost.

Aggreko is increasingly being approached to recommend and install temporary on-board temperature control equipment. This is being used to prevent corrosion, condensation and freezing, caused by unwanted moisture and salt from costal and ‘at sea’ conditions.

Using a variety of heating and dehumidification equipment, the temperature and humidity of internal air spaces can be controlled. This ensures void spaces within machinery and pipelines remain dry and prevents corrosion damage and moisture absorption into electrical cables and fittings. In this way, assets such as the engine room and bridge, together with sensitive electronic equipment, are protected.

By creating a stable environment, our rental equipment ensures assets remain in peak condition, no matter how long it takes before they are re-commissioned.

2. Activate a cost-effective power source

Whether hot or cold stacked, vessels will require some degree of power. This can be for routine regular maintenance tasks, powering temperature control equipment, or heating and lighting for any remaining crew. If a ship is laid-up at the docks, this could be provided from the dockyard’s mains supply, if adequate, or alternatively from temporary dock-side generators.

If at sea, mains power would need to remain turned-on to supply a sufficient amount of electricity, or alternatively could be supplied by hired generators.

One way our customers benefit from using our temporary generators is by shutting down their main engines and saving money. They can also avoid using existing over-sized and, consequently, inefficient emergency generators.

As we undertake the refueling, servicing and maintenance of our generators, customers can save additional money and manpower too.

3. Rigorously test equipment prior to redeployment

If market conditions pick-up, a plan will be needed to re-mobilise the vessel or rig, and its assets. As part of this process all power supplies, e.g generators, engines and turbines and HVAC equipment should be load tested to ensure it functions properly when returned to full working order.

As a loadbank hire company, the Aggreko team is experienced at providing this capability to load test the main generators, emergency generators, and any cooling systems on the vessel.

Rental solutions offer customers flexibility in a number of ways:

Temperature Control equipment can be adapted to weather conditions and climate

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. For example, desiccant dehumidifiers and heaters are a better solution for colder climates, whilst refrigeration equipment and chillers can be more effective in warmer regions. Renting equipment offers the flexibility to change equipment, dependent on climate. This can be important if vessels are being moved around the globe, or are docked in places where there are seasonal variances.

Generator power can be scaled up and down

Rental generators can be scaled up or down with very short lead times to supply variable power requirements, from power for lighting, to larger load requirements, such as heavy lifting equipment. This ensures that rigs and vessels can be speedily re-mobilised to tight deadlines.
