as a small corporation we need a goal and in order to carry out proper mining operations in 0.0 a Rorqual would be interesting for us in the long term.
As a returning player I am used to the fact that the role bonus for ships states what they can and cannot do. As I am still busy reading the patch notes of the last 15 years, I noticed the Industrial Jump Portal Generator which states: Can only be fitted to the Rorqual.
For a Titan this is stated in the role bonus: Can fit Jump Portal Generator.
For a Black Ops this is stated in the role bonus: Can fit Covert Jump Portal Generator.
The Rorqual role bonus does not say anything about an Industrial Jump Portal Generator, so can the Rorqual bridge ships or not, maybe only sometimes?
That would be interesting for us as a small corporation to know, as we would like to fly from Empirespace to mine in 0.0 in the future.
Conduit Jumps
A Black Ops Battleship or a Rorqual can instead conduit jump to their respective cyno. This both jumps them and to 30 eligible ships in a 10 km radius to the cyno. Unlike bridging, conduit jumping costs a flat amount of fuel no matter the size or mass of the affected ships, at a base value of 1000 isotopes, making conduit jumping a more efficient way of moving a smaller fleet around. A Rorqual can only conduit jump if its Industrial Core is disabled.
The Jump Portal Generator can only be fitted on a Titan, the Covert version only to a Black Ops Battleship, and the Industrial version to the Rorqual. They are high-slot passive modules which enable the bridge function of the ship. The module will visibly activate and cycle while the bridge is active, but cannot be manually activated.

The Rorqual as you can see can jump to industrial and regular cynos. It can also Conduit Jump to take along or create a bridge for industrial ships only.
As far as I know, yes, Porpoises can take the jump bridge.
Initially when the the industrial jump was introduced on the test server it wouldn’t take Porpoises and Orcas, only barges and mining frigates. People noted that Porpoises could just be taken along in the Rorqual’s bay and that it was unnecessary inconvenience that Porpoises couldn’t be taken along. Dunk Dinkle wrote a blog about it at the time.
While jump drives and jump bridges can target ‘easier’ cyno types, the type of bridge determines the ships that can pass through.
A Rorqual can bridge to industrial cynos and regular cynos, but only industrial ships can pass through.
A Black Ops battleship can bridge to industrial cynos, regular cynos and covert ops cynos, but only covert ops ships can pass through.
A Titan can bridge to regular cynos only and all ships without jump drive can pass through.
