Capacity Utilization
Percentages of the global shipping fleet that are not currently in active service provide a measure of the balance between the supply of ships and the demand for freight. These vessel idle rates include ships that are in dry dock for maintenance and those that are laid up because there is no cargo for them to carry. A low rate suggests a healthy market where almost every ship is earning revenue, while a high rate indicates an oversupply of capacity or a downturn in global trade.
Carriers Respond
Shipping lines use the decision to idle a ship as a way to control the supply of space on a trade lane and stabilize freight rates. When vessel idle rates rise, it is often a response to a period of low demand or a surplus of new ships entering the market. The practice allows companies to reduce their operating costs by cutting fuel and crew expenses for ships that would otherwise be sailing half-empty.
Analysts track these figures to predict the future direction of shipping prices and the financial health of the major ocean carriers. A sudden spike in the number of ships sitting out of service is a signal that the industry is bracing for a period of low activity.
Deciding Deployment
Selection of which ships to pull from service and for how long is a strategic calculation based on the age of the ship and the cost of reactivating it. Sustained vessel idle rates for older ships often lead to the decision to scrap the vessel and recycle the steel.
