Container shipping needs more consolidation to prevent owners from undercutting one another, a leading tonnage provider believes.

But Torben Kolln, managing ­director of Hamburg’s Leonhardt & Blumberg Shipmanagement, said shipowners remain reluctant to join the growing number of pools.

“Still lots of owners want to do their own chartering business, whereas it would make more sense to give their chartering business to these large consolida­ted interests,” he said.
