ClassNK Annual Report on Port State Control

Foreword
This Annual Report on Port State Control (PSC) summarizes deficiencies identified during PSC
inspections carried out in various countries around the world. This report is prepared with the objective ofbuilding awareness of the present state of PSC and thereby improving future onboard maintenance andinspections as well as Safety Management Systems.
The report consists of the following chapters.
Chapter 1: Measures adopted by ClassNK
Chapter 2: Statistical Analysis of Detained Ships Registered with ClassNK
Chapter 3: Statistical Analysis of NK SMC Ships Detained by PSC (ISM Code)
Chapter 4: Statistical Analysis of NK MLC Ships Detained by PSC (MLC, 2006)
Port State Control has been recognized as a very direct and effective means to reduce the number ofsubstandard ships as well as to improve the safety of ships at sea and to prevent marine pollution. The
activity of PSC worldwide has significantly been strengthened along with the increasing number of
amendments to the relevant international Conventions.
Further to the above, in order to carry out the effective implementation of port state responsibilities, many
countries have signed a Memorandum of Understanding (MOU) for regional cooperation among local
PSCs, and have agreed to establish a centralized & digitized database system and/or a harmonizedapproach.
The scope of PSC inspection has been extended from the hardware aspect of the ship to the software
aspect such as onboard maintenance or operational procedures ever since the ISM Code was adopted andapplied to all ships, and it is still expanding as more new concepts of regulations are introduced.
In line with the above progress of PSC, ClassNK has been working hard and will work harder to increase
the transparency of information related to PSC and to eliminate substandard vessels.

ClassNK Annual Report on Port State Control

Chapter 1
Measures Adopted by ClassNK
1.1 Cooperative assistance with PSC and treatment of deficiencies
When surveyors of the Society are notified of the detention of a ship classed with ClassNK, theSociety actively cooperates with the reporting PSC in a number of ways. The more direct of thesesteps include the following.
- Surveyors liaise with PSC to ensure that they are called in as soon as appropriate when deficiencies
related to class and/or statutory matters are identified.
- Surveyors liaise with PSC officers to ensure uniformity of interpretation of class and statutory
requirements.
- Surveyors provide PSC officers with background information, extracts from reports pertinent to theinspection, and details of outstanding recommendations of class and statutory items whenever sorequested by the PSC.
- Attending surveyors examine not only the condition of the deficiencies identified by the PSC
officers but also expand the scope of the survey for the general condition of the hull, machinery andequipment, or carry out the general examination to the extent of an annual survey if necessary,carefully considering the seriousness of any deficiencies when they attend ships that have been
subject to an intervention action by the PSC.
1.2 Treatment of inspection reports by PSC officers
When a surveyor receives an inspection report from PSC, the report is sent to the ClassNK Head
Office. The report is immediately examined by the experienced staff to identify the causes of the
deficiencies. In principle, this examination is carried out for all ships for which such reports arereceived, and the results are circulated to all sections concerned, as necessary. The results are also
reflected in a ClassNK PSC database that has been developed for the purpose of providing surveyors
with PSC related information electronically. The results of this examination are also submitted to theFlag State Administration of the ship, as required. Further, visits may also be made to the
management company or others, when deemed appropriate, to advise them of the relevant
deficiencies noted and to encourage them to more proactively improve the routine maintenance of
their ships and take other measures as necessary to ensure the highest levels of safe andenvironmentally friendly operation.
In cases where the deficiencies pointed out by the PSC are determined to be related to previous
surveys conducted by surveyors of the Society, those surveys are treated as a non-conforming service,
and appropriate corrective and preventive actions are taken in accordance with the ClassNK quality
system.

4.3 Study of MLC Detainable Deficiencies
This section introduces the studies of detainable deficiencies related to MLC, 2006 (hereafter, “MLC
detainable deficiencies”) and MLC deficiencies recorded as objective evidence of ISM detainable
deficiencies for NK MLC ships in 2022. In this Chapter, the deficiencies with Codes listed in Table 4.3.1 aredefined as MLC deficiencies.
The number of MLC detainable deficiencies per the deficiency code is shown in Table 4.3.2. Also, top major
MLC deficiencies regarded as objective evidence of ISM detainable deficiencies are shown in Table 4.3.3. As
for the MLC detainable deficiencies, “01220 - Seafarers' employment agreement (SEA)” was mostfrequently recorded on NK MLC ships in 2022.
On the other hand, the top 3 deficiencies recorded as objective evidence of ISM detainable deficiencies in
MLC deficiencies are as follows.
・ Top.1: “01220 - Seafarers' employment agreement (SEA)” (11)(Typical Deficiency: SEA expired)・ Top.2: “18204 – Calculation and payment of wages” (4)(Typical Deficiency: Salary not paid to seafarers)
・ Top.3: “01218 – Medical Certificate” (3)(Typical Deficiency: Medical Certificate expired)・ Top.3: “18302 – Sanitary facilities” (3)(Typical Deficiency: Sanitary facilities in unhygienic and damaged condition)
・ Top.3: “18312 – Galley, handling room (maintenance)” (3)(Typical Deficiency: Galley in dirty and unhygienic condition)
・ Top.3: “18424 – Steam pipes, pressure pipes, wires (insulation)” (3)(Typical Deficiency: Leakage from pipes)
