Someone asked a question about nomenclature the other day and it may have been on FB.  The name I know is “shipside door,” and it appears to be used in cases that the pilot’s ladder would exceed 9 meters (29.5′). 

In that case the pilot would enter/depart the ship via the shipside door.

Sometimes a combo of companionway and pilot’s ladder is used.

Other times it’s the shipside door and a ladder as below and

below.

Here’s one more batch.

Note the ladder above and the winch reel below.

 

All photos and any errors, WVD, who hopes this adds some nomenclature.
