Orientation pins are used to control the correct alignment of many types of BOPs.

Many BOP manufacturers use alignment pins which are manually inserted and removed. These are often difficult to insert or remove correctly in an offshore environment.

Schoolhill Hydraulic Engineering has developed a range of hydraulically powered orientation pins. The pin itself forms an integral part of a hydraulic cylinder, built into various types of API Flange. When the API flange is bolted into place on the BOP body, hydraulic lines are connected through the flange to the hydraulic cylinder which inserts or removes the orientation pin remotely. Pin sizes, cylinder lengths and API flange types all vary between different BOP manufacturers. Schoolhill Hydraulic Engineering can supply these units for most types of BOP.
