NEVER mind the parking problems for all these surplus container ships, which were built with such enthusiasm and now must be anchored somewhere until there is a need for them once again. What on earth are we to do with the containers they were designed to carry, and which are proving an enormous embarrassment to port authorities and others? We hear that Chinese ports in particular are over-run with empty boxes to such an extent that they are spilling out into the countryside. Shenzen is reputed to have some 450,000 of them piled up in gigantic mountains, against the day when somebody might want to put some cargo in one.
