The Bravo blow-out22/04/1977
On Friday, April 22, 1977, at ten o'clock in the evening, "Leave the Platform" sounded the alarm on Ekofisk 2/4 B. An uncontrolled blowout of oil and gas was underway in well B-14. Large quantities of oil and gas sprayed 5-6 meters up in the air before it went straight into the sea. What was not to happen had happened.

New hotel platform01/08/2013
Ekofisk 2/4 L is lifted into place. The new residential and field center platform 2/4 L replaces two older installations from the 1970s.
This occurred in 73 metres of water about 200 metres north-east of the Ekofisk Complex, where gas bubbled to the surface in an area about 40 metres in diameter.
Despite the introduction of round-the-clock logistical coordination from land, supply ships continued to collide with platforms in the Greater Ekofisk Area.
The tower on Ekofisk 2/4 H picked up a Mayday call on the afternoon of 1 May from a British fishing boat where a person had fallen overboard.
However, a large and heavy plant is needed to treat the seawater used for such waterflooding. That requires a lot of space and energy, and is thereby expensive.
