Serdar Soylu’s Latest Publication

Cellula’s own Serdar Soylu has just had his paper, “Precise trajectory control for an inspection class ROV”, published in Ocean Engineering. It is currently available online and will be printed in the physical journal in January, 2016.

Abstract

This work addresses the design, implementation and testing of a new precision guidance and control system for an inspection class remotely operated underwater vehicle (ROV). A new multi-input multi-output control law, composed of a model-based equivalent control signal and two adaptive signals, is presented. In the controller, the first adaptive signal is a PID signal with a novel adaptation law that enhances the controller performance and allows efficient fine tuning of the controller. The second adaptive signal continuously estimates the upper bound on the lumped uncertainty vector and acts as a corrective term for the equivalent control law. A Lyapunov based guidance algorithm is implemented that can tolerate significant uncertainties in the system kinematics. The effectiveness of the system on an ROV is demonstrated through field trials in sheltered waters. For the experimental work, an extended Kalman filter is used to for navigation, blending the on-board sensor measurements with a process model to produce an estimate of the vehicle dynamics. The collective guidance and navigation system are validated using high precision optical motion capture data. The system achieves decimetre-level precision, significantly extending the capabilities of the ROV for tasks requiring high precision position and velocity control.

Serdar Soylu to Present at IEEE Oceanic Engineering Society Event

Cellula Control Systems Engineer, Serdar Soylu, will be presenting at BCIT  on “Coordinated control of small, remotely operated and submerged vehicle-manipulator systems.”

Current submerged science projects such as VENUS and NEPTUNE have revealed the need for small, low-cost and easily deployed underwater remotely operated vehicle-manipulator (ROVM) systems. Unfortunately, existing small remotely operated underwater vehicles (ROV) are not equipped to complete the complex and interactive submerged tasks required for these projects. Adapting a popular small ROV into a ROVM that is capable of low-cost and time-efficient underwater manipulation will help to realize this objective.

The primary focus of this talk it to visit various technical building blocks that ultimately lead to such a coordinated control system for small ROVMs. Several model-based control methodologies are proposed to realize the desired motion produced by the redundancy resolution. For a unifies system (redundancy resolution and controller), a new human-machine interface (HMI) is designed that can facilitate the coordinated control of ROVM systems.

In the first phase of implementation, a small inspection-class ROV is adopted. To improve navigation, a navigation skid is designed that contains a Doppler Velocity Log, a compass, an intertial measurement unit, and acoustic position data. The theoretical and practical results illustrate that the proposed tools can transform. a small, low-cost ROVM system into a highly capable, time-efficient system that can complete complex subsea tasks.

Dr. Serdar Soylu received his B.E degree (with honors) in mechanical engineering from the Dokuz Eylul University in Turkey in 2002, and his M.A.Sc and Ph.D. degrees in mechanical engineering from the University of Victoria, Canada, in 2005 and 2011 respectively. He has been working for Cellula Robotics as a Control Systems Engineer since 2011 where he also held his NSERC Industrial Research and Development Fellowship (IRDF) from 2012 to 2014 on the automation of seafloor drills.

Successful Completion Subsea Well Intervention Valve Packs

Cellula Robotics Ltd. successfully delivers three subsea well intervention valve packs to Blue Ocean Technologies.

In December 2014, Cellula Robotics Ltd. (Cellula) was awarded a contract by Blue Ocean Technologies LLC. (Blue Ocean) to design and manufacture subsea valve packs for the Blue Ocean Riserless Intervention System (BORIS). The valve packs will operate in water depths down to 3000 meters to control critical functions of the BORIS. The project will be designed to the rigorous requirements of ISO 13628-6 and other applicable industry standards.

For this project, Cellula upgraded their manifold testing facility with a high pressure, water based control fluids, flushing station that can clean to NAS 1634 Class 6. The new flushing station reduces the time taken during integration to reach the required cleanliness standard.

Blue Ocean Technologies LLC., which is based in Conroe, Texas, was established in 2008 and became an early player in Riserless Subsea Intervention. The company founders have extensive experience in the field of riserless intervention and the broader organization has extensive knowledge and design experience in subsea and well intervention with a proven riserless intervention track record in water depths in excess of 8,200 feet. In addition, the Blue Ocean team has field-proven capabilities to perform subsea well infrastructure diagnostics, interventions, work overs, remediation, well plugging and abandonment (P&A).
