At least the ship had a fresh air filter and it's windshield washer reservoir topped off with tap water.
Luxury cruise ship lost engines on Sat due low level of lubricating oil

Yeah, I watched this news while onboard the Carnival Valor headed out to Cozumel.
Just made it back to land, all fine for us great trip.

Like roofless said. But specifically called a "dry" sump because when oil hits the oil pan (usually of a compact design), it is immediately sucked out of the oil pan (no reservoir of oil remains) by a "scavenge pump" and pumped into a tank that is usually baffled to stabilize the oil from sloshing and remove any air.
There is another pump that sucks the oil from the bottom from the tank and pumps it into the engine as a traditional oil pump would, providing pressure and lubrication.
Dry sump systems may be of multiple "stages". There may be multiple scavenge pump sucking oil out of the engine from multiple points of the oil pan, cylinder heads, or cylinder valley (if applicable).
This allows for a nearly unlimited amount of oil capacity, since oil capacity is not based on pan size, but the size of the remote tank.
It also allows for a much larger column of oil to be placed above the oil pressure pump's pickup since it is not based on pan design.
A good dry sump tank is high and narrow, so even extreme G-Forces can not pull the oil away from the pickup of the oil pressure pump. Since the sump is "dry", there is no oil reservoir to wind up the crank and cause windage losses.
The scavenge pumps also pull a vacuum on the crankcase, causing less whipping of air in the crankcase, and leaving the Pistons with less air to pump around, which reduces pumping losses.
What about a dret sump? Some Corvette owners have the oiling systems on their engines changed from factory, to gain more power....

Did you pass a note to the Captain of the Love Boat to check the oil levels and top off immediately? I'll bet they all ran down and checked them when they heard this, right?!
