Hot-lay up: Up to 3 months with 24 hour reactivation

​

During hot lay-up, the vessel is held within Classification and Flag State requirements, although crew numbers may be reduced to certified minimum safety crewing limits. Machinery is kept operational and the vessel is located in an area close to potential cargo trade routes.

 

Warm lay-up: From 4-12 months with 1 week reactivation

​

Vessel crewing is reduced to below the trading limit and in agreement with the Flag State, Classification Society, insurers and local authorities.

 

Cold lay-up: From 1-5 years with 3 week reactivation

​

The vessel crewing is in line with emergency requirements to deal with fire, flooding, mooring and security watch. Cold ship lay-up locations are generally remote and access to the vessel may be limited. Upon reactivation, the vessel may need to go direct to dry dock before trading, depending on the extent of any hull marine growth.

 

Long-term lay-up: From 5+ years with 3 month reactivation

​

In this extended condition, preparations are comprehensive as original manufacturers are consulted for critical equipment. Any remedial work done on reactivation is likely to be extensive and unpredictable, such as renewal of alarm systems that may have become obsolete. For long-term lay-ups, several vessels are laid up side-by-side to minimise supervision costs.
