Tender-assisted rigs are specialized offshore drilling platforms designed to support the drilling process in deep water. They consist of a floating vessel, known as a tender, which carries equipment and supplies, while a drilling unit is positioned nearby. This setup allows for efficient operations in challenging marine environments. The tender provides logistical support, including crew accommodations and storage for drilling materials. By using this system, operators can enhance safety and reduce costs, as the tender can be easily moved to different locations, making it a flexible solution for offshore drilling projects.
