In taking a decision concerning the rectification of a deficiency or detention of a vessel, the Port State Control Officer will have to take into consideration the results of the more detailed inspection. The Port State Control Officer will exercise professional judgement in determining whether to detain the vessel until the deficiencies are rectified or to allow the vessel to sail with certain deficiencies without unreasonable danger to safety, health or the environment, having also considered the specific circumstances of the intended voyage.
