What is a port state control officer?

Port State Control Officers (PSCOs) are maritime professionals who inspect foreign ships in national ports to ensure they comply with international safety, security, and environmental regulations. They play a crucial role in enforcing standards set by the International Maritime Organization (IMO) and other regulatory bodies. PSCOs check for compliance with conventions such as SOLAS, MARPOL, and STCW, and can detain vessels found to have serious deficiencies. Their work helps prevent substandard ships from operating, thereby safeguarding lives, property, and the marine environment.
