A Friesland ship in 1655 named Omlandia

I am now receiving photographs of documents from 1655. There is one page that shows a ship of the Admiralty of Friesland that is named Omlandia. This is a ship of approximately the dimensions of the Zevenwolden that was sunk at the Battle of Scheveningen. The Omlandia was also 122ft long. The Omlandia only carried 30 guns, unlike the Zevenwolden, which carried between 34 and 38 guns at different dates. The ship in this document doesn't match other listing that I have seen for a Friesland Omlandia in service in 1655.
