A valid access permit is required to enter a certified ISPS area. Persons in the area must be prepared to prove their identity and indicate the purpose of their visit. Port of Naantali recommends that employees of companies that operate in the area regularly keep their photo ID visible at all times to ease the supervision.
The permits are managed in a distributed manner between the port and the port operators and they are applied for from the organisation on which the visit is based on. The permit can be assigned to one person or vehicle and it can be continuous, temporary or one-time.
