Of 62 International Safety Management (ISM) Code inspections carried out during a concentrated campaign last year, Hong Kong port-state control authorities detained only one vessel for non-compliance.
The campaign, between July 1 and September 30, led to 63 detentions involving 61 vessels in the Asia-Pacific region.
Of those, 28 had been audited by classification societies and 22 were audited by the flag states.
'The auditing bodies of the remaining 11 ships could not be identified as they were without proper ISM certification,' said the Asia-Pacific region port-state control committee.
It said that while it was still too early to assess the success of the ISM Code, it was still a positive sign that the number of vessels detained for ISM Code non-compliance was not too high.
The detained vessels either had no proper certification or had serious non-conformities in ship-safety management systems.
The detentions represented an average 3.5 per cent of vessels inspected.
During the campaign period, a total of 1,820 inspections were carried out on vessels to which the ISM Code was applicable.
Almost 70 per cent of the vessels inspected were bulk carriers.
The second-largest category of vessels to be inspected was oil tankers with 267 inspections, equivalent to about 15 per cent.
The statement said that while bulk carriers were the largest category of vessels inspected, passenger ships were found to have the highest detention percentage.
Of the 53 vessels inspected, four were detained, giving a 7.5 per cent detention rate. Two of four vessels were detained for not having appropriate ISM Code certification on board.
Six chemical tankers were detained out of 138 inspections, forming the second-highest detention percentage.
This was followed by bulk carriers with 45 detentions out of 1,272 inspections.
Seven oil tankers and one gas carrier also were detained for ISM Code non-compliance.
