Long Term Storage of Ships During COVID-19 Shutdown
Now, more than ever, companies need to protect their capital assets and WIP-cycle components in this time of uncertainty and unplanned shutdowns. Due to the impact of COVID-19, society must embrace the adage, “Hope for the best. Plan for the worst.” Even after this is over, it will take time for the supply and demand sides of the market to synchronize. To ease the process, equipment needs to be protected in such a manner that it can be put back into commission with minimal effort to meet market demand.
Cortec® Corp. is working hard during this crisis to offer help and support across all industry sectors, putting its technical expertise at the disposal of its customers to assist them in the following areas:
- Preservation of laid up vessels
- Preservation of material in inventory
As manufacturing facilities are shutting down and going into a state of forced layup for an indefinite period, keeping these assets corrosion-free is essential to ensuring they can be reinstated and operational as quickly and cost-effectively as possible. Corrosion is a major problem for idle equipment and assets, especially in the presence of moist, salt-laden air or fluctuating humidity that forms condensation on electrical systems, rotating equipment, hydraulics, bolts, valves, and motors, to name a few components. Corrosion results in
- Premature equipment failure
- Unnecessary and non-budgeted repair and replacement costs
- Costly delays in reinstatement of vehicles, plants, and equipment
How Can We Combat This?
Vapor phase Corrosion Inhibitor Technology is designed to protect assets and equipment during shutdown and storage. It is based on the formation of a molecular barrier that protects ferrous and non-ferrous metal surfaces from oxygen and electrolytes, thus breaking the corrosion cycle. Cortec® VpCI® materials provide total corrosion protection to equipment of all types, from small electronic components to large oil and gas module piping internals.
