# Maintain Voyages

The details of a voyage can be edited in the **Voyages** module.

When you have [located the voyage](https://docs.dataloy.com/release-8.16/voyage-management-system/step-by-step-guides/voyages/find-voyages), click it and the details will show in a drawer or panel on the right hand side. Field values can be edited directly.

{% hint style="info" %}

#### Change of vessel and ballast port

Vessel and ballast port can only be changed when the voyage status is "estimate" or "unallocated".

**Edit estimates permissions**

With the preference 'Share voyage' you can indicate if estimate voyages can be edited by anyone or only by the creator and administrators

* If 'Share voyage' is set to true, estimate voyages and template voyages is editable by all users
* If 'Share voyage' is set to false, estimate voyages and template voyages is editable only by the creator and administrators

### Tiles

Tiles show the key values like TCE,  Days Total, Distance Total, Bunker Consumption, EEOI, Days In Port, of the voyage.

### FAQ: Why is Excl. Offhire higher than TCE?

TCE is calculated as: *Contribution divided by Total Days of the Voyage*\
TCE Excl. Offhire is: *Contribution divided by (Total Days of the Voyage - Total Days Offhire)*

'TCE Excluding Offhire' will display the TC Equivalent using the remaining total days after excluding/subtracting the days offhire. As a result of dividing by a smaller number, it will always be a higher number than regular TCE.

### Sections

Sections are used to show the most important information about a sub-item of the voyage. Some sections have an **Open**<img src="https://content.gitbook.com/content/uZ9lzqgHX4JL1Df67xog/blobs/5IerbaEgsZUPhvzjZurd/open-in-new.svg" alt="" data-size="line">button to open the section's item in a new drawer.

Voyages on a time charter will have a "TC contract" section, while all other voyages will have a "Performance Cargo" section instead.
