Such as when the government offers a safety net to incentivize the private sector to invest in building large infrastructure projects. If an IPP is offered a safety net it, it could be in the form of a guarantee that the grid will purchase a certain percentage of the plants electricity output
A weak spot which is sometimes intentionally put in the drillstring so that if pressure exceeds a predetermined amount, the safety joint will break off and the rest of the drillstring can be saved.
Control and reduction of risks at specific sites and/or work processes
Safety Distances
There are three safety distance measures used:
•House Burning Distance (HBD), the safe distance between a house and the energy infrastructure, such as a natural gas pipeline;
•Safe Escape Distance (SED), which refers to the safety range for population exposed to existing energy structures;
•Safe Distance (ESD), which refers to a range in which there are no potential ignitable and flammable sources.
The principle of a sacrificial anode is in connecting an external anode to the material to be protected from corrosion (such as a subsea pipeline) and passing of an electrical DC current so that the whole area of the metal surface becomes cathodic and therefore does not corrode. The anode electrolytically decomposes while the object remains free of damage
