What Is a PDA in Shipping?

When a vessel prepares to dock at a port, one of the first steps behind the scenes is the creation of a Proforma Disbursement Account, commonly known as a PDA. Think of it as a detailed financial preview—an estimate of all the costs that will likely be incurred during the ship’s visit.

This document is typically prepared by a local shipping agent acting on behalf of the vessel operator. The agent gathers information about port fees, pilotage, tug assistance, mooring services, waste disposal, customs clearance, crew-related expenses, and any other potential charges. The goal? To provide a clear picture of what the port call will cost before it even happens.

The PDA plays a crucial role in budgeting and financial planning for shipping lines. It allows operators to anticipate expenditures and helps avoid surprises once the vessel is alongside the berth. Since actual costs can vary slightly depending on delays or unexpected services, the PDA is an estimate—not a final invoice—but it’s usually very close to the mark.

In practice, the PDA is shared with the vessel owner or charterer for approval, and often serves as the basis for securing funds (known as disbursements) to cover port expenses. Once the ship completes its port call, a final disbursement account is issued, reconciling the actual costs with the original PDA.

So, while it may sound like financial jargon, the PDA is a vital tool in smooth maritime operations. It reflects the intricate coordination between ships, agents, and ports—ensuring that every dollar spent is accounted for, and every visit runs as efficiently as possible.
