For gas projects and hydrocarbon derivatives, these agreements are essential for the development project. Financiers will not lend the funds and boards will not approve the project if there are no customers related to the product. The purchase agreement has an impact on the practical conclusion. If there are take-off or payment agreements, it is important that the project is ready to deliver the product from the start date of the acceptance agreement, or that it risks sanctions. Another feature of the EPC contract is that the EPC contractor enters into separate agreements with contractors, suppliers, subcontractors, subcontractors, subcontractors, etc. This is advantageous for the owner or contracting entity of the project, since it assumes full responsibility for the project by the EPC Contractor and in the event of a dispute between the EPC Contractor and a party to the sub-agreements, it will settle the dispute without the owner or the client being required to participate in the dispute. In most cases, the EPC Contractor has a right of recourse against a party to a sub-agreement that was responsible for the loss or damage. . . .
