There are straps over all of the computers, of course. In our bedrooms, the television is bolted to the wall. In the library, there is a strap that runs across the front of the books. The chairs in the lab do not have wheels, and the floor is textured to increase friction. We haven't had any rough seas since I've boarded the ship, but they are always prepared.
Storms arrive quickly around here, and they always want to be ready.
We are very far away from any help. If something breaks, it is up to the crew to fix it. About every tool imaginable is available on this ship. There are people on board who can fix anything from computers to sediment coring equipment.
