Deliver consistent performance and maintain continuity in critical subsea environments
talk to an expertAchieve faster, safer subsea completions through precise orientation. The Optime tubing hanger orientation system (OTHOS) reduces rig time, improves safety, and simplifies offshore operations. It is a compact, gyro-guided design that supports vertical subsea tree applications without traditional orientation joints (THOJ) or complex blowout preventer (BOP) alignment systems. OTHOS helps ensure clockwise tubing hanger orientation regardless of BOP position.
Precision within ±1.5° prevents costly misalignment and keeps operations on schedule. Real-time heading and force data help operators to make confident decisions quickly. Operators cut mobilization time and reduce costs by removing unnecessary pre-run testing. A compact structure maximizes rig space and integrates seamlessly within the BOP for efficiency.
Simplify orientation and reduce red-zone exposure with a solution built for precision, safety, and efficiency. OTHOS provides accurate orientation that minimizes risk, streamline operations, and enables reliable subsea completions that meet performance goals.
