TEHRAN (PetroIran) -- Drilling Company International Limited (DCI) has successfully driven 26-inch threaded pipes at Ilam Field for the first time in Iran.
Hamidreza Saghafi, CEO of DCI, stated in an interview: “For the first time at Ilam 1 Platform, threaded pipes have been used to create conductor pipes by DCI by using moling method. The company had previously adopted the method in Siri project.”
Considering the importance of the project and the need to expedite the executive operation, since there had been no experience of moling for threaded pipes in the Iranian oil industry, a team of the senior experts in the engineering department of the Iranian Offshore Oil Company (IOOC) along with senior technical experts at DCI held various meetings to discuss the feasibility and potential risks of application of the method, he added.
Saghafi stated: “In the next step, according to the employer's agreement to use threaded pipes, calculations and engineering documents related to the Conduction of Pipe Driving Analysis and also the penetration depth of conductor pipes based on the available geotechnical data of the sea bed were considered by both the employer and the contractor of the project.”
He went on to say that the tools used in this operation included an operational ship with effective maneuverability (DSV-RYAN), a diesel hammer used for moling the conductor pipes as well as cranes used to lift the pipes and the hammers, which were approved by the employer.
