English Other Ships, Sailing, Maritime abbreviation, part of a ship

Hello everyone. I haven’t been able to find out the meaning of the abbreviation “conn”, referring to a part of a ship. In my text, it occurs dozens of times in sentences like this:
“Underway as before. 1520 BMC Smith relieved the deck. 1705 BMC Williams relieved the deck and the **conn**. 1730 BMC Smith relieved the deck and LTJG Psimer relieved the **conn**. 1735 prepared to hoist in Rat 2. 1745 Rat 2 cradled and secured for sea. 1747 observed sunset energized navigation lights”

Many thanks in advance for your help,
Manuel
