Port congestion

Inadequate seaport facilities
Port traffic congestion
Port service can be said to be inadequate when traffic has to be restricted for lack of port capacity or when traffic uses a port only at excessive cost. The consequences of a failure to provide proper port capacity before the increased traffic arrives are clearly illustrated by the recent congestion in many ports of the world, in particular in developing countries. The enormous sums of money lost through congestion would often have been sufficient to build a lavish system of modern ports.
