The Datapack that you are looking for is inside the container hanging down from the crane. You can get inside the container by gliding towards it, or by standing on the rooftop's edge and dropping down from it.
Explore the rooftop, where you will find a big cage. Start by spreading the explosive gel over the inactive button shown in the above screenshot. Use the batarang ,and hit the active button on the left with the gadget.
You can now enter the venting shaft, thanks to which you will reach the cage in the center. Detonate the explosive gel now, thanks to which you will unlock another venting shaft. It will take you to the Datapack.
Datapack 7 (The Final Offer ship)
You can obtain the collectible while exploring the Western part of the ship's Deck 1. Stop after you reach the place where, usually, you pull the floating platform that you can see in the distance. Instead of doing that, look up and use the claw on the anchor point shown in the screenshot. After a part of the ceiling collapses, get there using the hook and explore the place, thanks to which you will find the Datapack.
Datapack 8 (The Final Offer ship)
You can obtain the collectible while exploring the Western part of the ship's Deck 1. It is in the flooded part of the corridor which you can get through using the grapple. Extend the rope and jump onto it. Stop after you reach the spot above the collectible shown in the screenshot. Unfortunately, you cannot obtain the Datapack at a distance so, use the glue grenade to create a floating platform. Jump down onto the platform, approach the collectible and collect it.
Datapack 9 (The Final Offer ship)
The collectible is in the Southern part of the Boiler Deck and you can reach it by taking the narrow passage with steam leaking, i.e. the same one that you took the last time you visited this location. Stop after you reach the enclosed area on the higher level (the above screenshot). Use a glue grenade here to insulate the pipe on the right and unlock access to the Datapack.
Datapack 10 (The Final Offer ship)
The collectible is in the Gun Shop, i.e. in the first location on the ship that you explore. After you walk under the deck, turn right and locate the manhole shown in the screenshot. Use the claw twice, here - first to open the manhole and the second one to get the Datapack.
For finding all of the datapacks, you are rewarded with the audio file connected with Alberto Falcone.
