Can someone explain....

when the ocean is on fire, how pumping water onto it helps:


By spraying a lot of water at the base of the fire, you dilute the oil and reduce the intensity of the flames. Water isn't fuel; oil is. That's how 90% of oil rig fires are extinguished.

The one in the back spraying laughably far away is comical without considering what it's actually doing (diluting the oil).

But wasn't this a leak from a gas pipeline?

A fine spray has 2 functions, first the water displaces air thus starving the fire of oxygen. And cooling/killing the flames.

Gas is pumped in liquid form due to pressure. Else, the principle remains the same. Spraying water will reduce gas concentration.
Are you sure? The critical temperature for methane is -82C. They would need a liquefaction cooling system at the wellhead to liquefy it. I thought that had to be done onshore in a large facility, and that the gas-gathering from the wells was in gas form.

Apparently it depends on the type of gas and the type of formation.
