# Port Call Bunkers and Overview

Port call Overview can be found inside the Port Call module (see ref. 1):

<figure><img src="/files/G0iMrHeYW9hSgfCVcxHz" alt=""><figcaption><p>Ref. 1: Port Call Module</p></figcaption></figure>

The Overview tab is split into three essential sections: 1. Port and Bunkers; 2. Sea Passages; 3. Port Details;

#### Port and Bunkers

This section provides a detailed insight into fuel consumption, including the calculation of remaining onboard fuel. It also features an overview of port call events (e.g., Arrival) with respective consumption and editable values (slightly darker background cells). ROB per event and respective dates can be altered or locked (by clicking the lock icon).

Example (ref. 1):&#x20;

Stockholm is the first port call on a voyage. The voyage has 800 MT of remaining onboard FO and 600 MT remaining onboard MGO fuel. The arrival event (ROB) contains a summary of remaining fuel, accounting for the consumption at sea (consumption between ballast/previous port call departure and current port call arrival): 787.868 MT of FO and 562.131 LS MGO. The same logic applies to future events (e.g., Departure ROB would correspond to Arrival ROB minus consumption in Port), further port calls, and even the next consecutive voyages.

Initial opening balances per bunker type can be added in the Voyage module, the [Bunkers](/release-7.2/voyage-management-system/step-by-step-guides/voyages/voyage-bunkers.md) tab.

#### Sea Passages

The Sea Passages section includes sailing-related port call data that can be modified.

#### Port Details

This section provides an overview of the formal and financial sides.&#x20;

The top row suggests the days-related information, answering such questions as 'What the waiting days are?', 'How much extra time has the vessel spent in port?', 'How much time did it take to Load/Discharge Cargo?'.

The middle row contains the cost-related data - port cost, and a function to use the total of 'Our' costs from [Service Orders](/release-7.2/voyage-management-system/step-by-step-guides/service-orders.md).
