A DETECTION SYSTEM FOR A WELLSITE AND METHOD OF USING SAME

A detection system, and method, for an offshore wellsite (100), the detection system comprising: a wellsite component (127) deployable from a surface rig (106) of a surface system (102) of the offshore wellsite (100) through a conduit (112) of a subsurface system of the offshore wellsite to the subsea BOP, wherein the subsea BOP includes a bore to receive the wellsite component therethrough and a sealing device (126) to seal a wellbore extending from the wellhead; a plurality of axially spaced equipment units (131) disposed along the wellsite component (127); and a plurality of axially spaced base units (133) positioned along the bore of the subsea BOP, wherein each base unit (133) is configured to detect each of the equipment units (131) when the equipment unit (133) is positioned proximal the base unit (133), and wherein the base units (133) are configured to communicate with the equipment units (131) to determine whether one of the equipment units (131) is axially aligned with one of the base units (133) to position the wellsite component (127) in a desired location relative to the subsea BOP.
