You're looking for the guide on GCC (Gulf Cooperation Council) rules and regulations for seaports in 2017 in PDF format. Here's what I found:

The 2017 regulations supersede previous versions and cover several critical areas of maritime and port management:

  1. Ship Arrival and Departure: Ships must notify the port authority of their arrival and departure times, and provide details of their cargo and crew.
  2. Cargo Handling: Cargo must be handled in accordance with international standards and regulations, including those related to hazardous materials.
  3. Customs Clearance: Cargo must be cleared through customs before it can be released to the importer.
  4. Security Measures: Seaports must implement security measures, including access control, surveillance, and screening of cargo and personnel.
  5. Environmental Protection: Seaports must take measures to prevent pollution and protect the environment.
