The engineering and installation practices of conductors play a crucial role in a well’s integrity. This is especially true when load contributors such as drilling risers, casing strings, operational equipment, subsea trees, production risers, and more are factored into the equation. Historically, with the advantage of being faster than drilling and cementing, jetting proved to be the industry standard of installing conductors into the seabed.
Driving of conductors gradually took over as the best-practice method in shallow water locations. However, in recent years driving proved to be an option for deepwater sites. In an effort to uncover the reasons for this trend, InterMoor, an Acteon company, has drawn on its experience from the past five years of successfully completing deepwater conductor driving projects in offshore Brazil. A deepwater hammer spread provided by InterMoor’s sister company MENCK enabled driving in depths up to 6300 feet (1920 m) during these campaigns and provided an abundance of field data on the driving process, proving its safety and effectiveness.
