The Ship Security Officer (SSO) should advise the Port Facility Security Officer (PFSO) without delay.

Costs associated with the ship's employment, including costs of bunker fuel, canal tolls, light dues, port charges (including pilotage, towage, berth charges, agency fees, linesmen's charges, etc.), passenger-handling costs, and cargo- handling costs.

There is also a Beijing Form, a Moscow Form, a Hamburg Form and others.
