Protecting agent vs charterers’ agent is a distinction every owner should understand before a voyage begins.
A protecting agent is the owner’s own representative in port when someone else has already appointed the vessel’s main agent. This usually happens on a charter voyage, where the charterer nominates the agent handling day-to-day operations, and the owner brings in a second party purely to watch over its interests.
Understanding this distinction matters before any voyage begins, since it shapes who pays which fees and who signs off on the disbursement account at the end of the call.
Who actually runs the port call
The charterers’ agent runs the actual port call. Booking the berth, coordinating cargo operations, arranging pilots and tugs, clearing customs, all of this sits with the agent the charterer appoints under the charter party.
This agent works for the charterer’s account and answers to the charterer’s instructions, even though the vessel technically belongs to someone else.
The protecting agent’s job looks different. Rather than running operations, this agent checks that the charterers’ agent is following the charter party correctly, verifies cargo quantities and condition on the owner’s behalf, and reports back on anything that could affect the owner’s liability. SeaHarbor Agencies regularly fills this role for owners calling Curaçao, offering an independent set of eyes even when another agent already holds the appointment.
The question of ship agency vs port agency often comes up here too, since the two terms get used loosely. A port agent is really just a ship agent operating within a single port call, and the roles of a port agent stay largely the same whether that agent works for the owner, the charterer, or in a protecting capacity.
How agency fees and disbursement accounts split between owner and charterer
Agency fees follow the appointment. The charterer pays the charterers’ agent’s fee as part of running the voyage, while the owner separately pays the protecting agent for oversight services. Both fees appear in disbursement accounts, though on different documents tied to different principals.
FONASBA, the global body representing ship agents and brokers, defines these roles clearly and notes that in practice an agent can act for any party to a voyage, in whatever capacity the principal agrees to.
Disbursement accounts themselves follow a standard structure. A proforma disbursement account estimates costs before arrival, covering pilotage, towage, port dues and the agent’s own fee. Once the vessel sails, the agent issues a final account reconciled against actual invoices.
Owners and charterers who want to protect against inflated or disputed charges often lean on industry bodies for support here. BIMCO, for instance, runs an intervention service that helps members recover outstanding balances when agents or brokers have trouble collecting outlays or agency fees.
Deciding whether a protecting agent is worth appointing
Getting the appointment structure right at the start of a voyage avoids confusion later. An owner unsure whether a protecting agent is worth the extra cost should weigh the value of independent verification against the size of the charter, particularly on voyages where cargo quantity or condition disputes are common.
The same logic applies whether the port call happens under a voyage charter or a time charter, a distinction that shapes agency arrangements in its own right.
For vessels calling the Dutch Caribbean, working with an experienced port agency in Curaçao or port agency in Aruba means both roles, protecting and operational, are available locally, with tonnage-based dues already calculated correctly before the vessel arrives.
