Deepwater Drilling and Production Technology - DDP

Petroskills Registerbutton

This 3-day course describes the deepwater technology that has been developed and implemented in the last few years. It is illustrated with extensive graphics plus over 100 animated and photographic videos of the latest equipment and the most recent actual DW field developments. Each of the DW system components is discussed in terms of its engineering challenges. Introducing each technology area is a brief description of the conventional water depth technology from which the new, DW concepts have evolved. The bases for selection of particular field configurations are discussed.

Individuals with at least some awareness of basic offshore engineering and operations. Technical staff, project engineers, engineering discipline leads, engineering specialists and operating staff find this course accelerates their capability to contribute to deepwater development planning, design and construction projects and field operations.
