Shipboard maintenance and operation
A shipowner always needs to ensure that the ship is properly maintained and operated so that it remains in conformance with all applicable international standards and requirements.
Such careful maintenance and operation of the ship will go a long way to avoiding any unnecessary problems during a PSC inspection.
Most lapses and deficiencies onboard can be prevented by doing various operational checks, maintenance and repairs, etc. of machinery and equipment regularly. This includes maintaining shipboard records properly, confirming the validity of all certificates and documents as well as verifying the survey dates of all relevant class and statutory surveys.
In addition, always taking care to keep things onboard ship in good order and striving to improve the shipboard environment can go a long way to not only enhancing safety in daily operations, but is also an effective means of coping with PSC inspections. (Indeed, as the old adage says, “an ounce of prevention is worth a pound of cure.” ) The Society has prepared “Good Maintenance On Board Ships” and “ARRIVAL CHECKLIST for PSC” as a ship management checklist and tool for use during voyages to help Masters and operators achieve these goals more easily.

What is Port State Control?
Port State control, or PSC, is the exercise of the right of a port State, when granting permission to a foreign flagged ship to enter a port of the port State, to inspect the vessel to ensure that it meets international safety, pollution and other requirements.
Various international standards and conventions, such as the SOLAS Convention, MARPOL Convention, and the International Load Line Convention, have been enacted in order to promote the safety of life and property at sea and to protect the marine environment with respect to oceangoing ships. Although the flag State and owner of a ship have fundamental responsibility for ensuring that these requirements are implemented, supervision by the flag State is many times insufficient. There is also often a lack of adequate competence and experience on the part of ship crews and others that can all too often have an adverse impact on safety, as well.
PSC has been established as a means of proactively complementing the role of flag States with the primary aims of improving ship safety and eliminating substandard ships. This consists of conducting inspections of various aspects of a ship once it has arrived in port, including the safety of life and property onboard the ship, prevention of pollution by the ship, and the living and working conditions onboard the ship.
Activities of the Society
Whenever the Society receives a PSC inspection report from a port State Administration, an investigation is carried out at the Head Office of the Society to determine the cause of the deficiency. The shipowner and flag State are then informed of the results of the investigation, and the results are also input into a dedicated database on PSC maintained by the Society. Effective use is also made of this information through the publication of the Annual Report on Port State Control, and other materials by the Society.
In addition, “Technical Information” releases are issued to provide updates and various notices on a range of topics including information on PSC, whenever necessary.
