As a general rule, a knock for knock agreement means that any party working at an oil and gas site – the operator and each contractor – agrees to protect and keep harmless all other parties from violations by the employees and representatives of that party, as well as from the destruction or deterioration of that party`s property. This award is not based on the fault or fault of the party whose personnel have been injured or whose property has been damaged. The goal is to effectively defend and pay a claim by making a single party liable for the loss. . . .
