The UK's Baltic Exchange aims to promote transparency for owners with a new assessment of vessel operating costs.

The Baltic Operating Expense Index (BOI) will be published every three months.

It will be based on assessments from three ship managers, Anglo-Eastern, Columbia Shipmanagement and Fleet Management, which together handle more than 1,800 ships.

Additional companies are expected to join the panel in the future and a residual price calculation added later this year, the Baltic said.
