Leading classification society ClassNK has released its annual report on Port State Control. The report aims to assist ship operators and management companies in maintaining compliant operations by providing information about ships detained by PSC as well as deficiencies that were found on board from many port states in 2016.PSC inspections ensure that vessels departing the port meet international standards and have proved to be highly effective in eliminating substandard ships that are in operation. They oversee not only the physical structuresand components of a ship, but also examine operations related to safety management systems and labor conditions such as wages and hours of rest withregards to MLC, 2006. Over 100 port states have signed a Memorandum of Understanding (MOU) over the years and established a harmonized system forPort State Control to strengthen PSC-related activities, ensuring maritime safety, decent working and living conditions, and reducing maritime pollution.To help its customers improve safety management systems and overall fleet quality, ClassNK has included a breakdown of deficiencies which shows that fire safety-related deficiencies continue to be the most frequent detainable deficiencies item. ISM, lifesaving appliances and safety of navigation also remain major items where many detainable deficiencies are found.The ClassNK report also provides detailed analyses on PSC detentions by flag state, port state, ship type, ship size, and ship’s age as well as a summary of major amendments made to international conventions such as the SOLAS Convention. These amendments have further widened the scope of PSCinspections, a trend that will undoubtedly continue as the rules applied to ships increase and diversify.
