For the first time, the port state detention figures from the world's three major port state control regions have been married together. The statistics give a worldwide view of the classification societies' performance, showing that the DNV classed fleet achieved the lowest detention ratio in 1999. The DNV classed vessels came out top with 3 per cent of ships inspected detained, proving excellent fleet performance.
The statistics are based upon accumulated figures from the three major port state regimes in the world Europe & Canada (Paris MOU), Asia & Pacific (Tokyo MOU) and USA (USCG). The DNV classed fleet achieved the best performance in each regime. This represents more than 90% of worldwide port state detentions, with Paris MOU accounting for more than 50%, Tokyo MOU more than 30% and USA about 10%.
Accumulated detention performance in the above major port state regimes can be regarded as a worldwide performance indicator, split on the various class societies.
The number two position is jointly held by Japan's Class NK and Germanischer Lloyd, with a detention ratio of a little more than 4%. However, the statistics are based on all detentions in the three major regions, not simply those defined as class-related. DNV intends to undertake the detention analysis on a regular basis.
