... Abstract The authors will present examples of how revising base layer control strategies have resulted in improved compressor operation in a mature deep-water asset. The revised control strategies have resulted in improved production and capacity whilst reducing greenhouse gas production...

... recommendations for how to operate a TAM unit, and this is presented in a companion paper at OTC 2023 / 1 /. The parametric study was performed in time domain for 3 TAM units of different sizes at 3 water depths and a range of metocean conditions and controller settings. Both a Kalman filter controller...

... of offshore fields, both subsea and topside, to lower emissions. To meet the technical challenges, a significant effort is put into research and technology development by academia and the industry. ABB, a specialist in electrical equipment and control systems, and OneSubsea, a specialist in subsea processing...

... to the technology landscape will fundamentally alter the nature of well construction and the interactions pertaining to well design, operation, and maintenance. One key element of well construction is process safety. To prevent incidents, well control assurance programs are created to ensure subsurface hazards...

... Modern offshore processes can now generate a large amount of high-resolution data, and this data is now being collected on various data collection systems. The traditional approach of process data is real time changes in operations (controllers or human operators taking action) or in the case...

.... Experimental analysis on both controlled environments (laboratorial and sheltered waters) and operational environment (open waters) are under execution. Not only results on sensory data processing but also the challenges overcome on the joint task of landing a drone on a moving vessel are presented...

.... This will be the first multiphase boosting system with all electric control system and in addition we are also producing to and controlling the system from two different hosts. The pump is using the new HV motor, simplifying and reducing costs of the system. The boosting system will comprise of a foundation structure...

... of the complete subsea power system with two VSDs in a parallel configuration combined with subsea switchgear and controls. The new solution will ultimately mean operators can free up topside space, or use no topside installation whatsoever, yielding significant cost and safety benefits. It is an extremely...

... Abstract A valuable property of a turret moored FPSO is its ability to weathervane or self adjust its heading to the varying metocean environment. Still, heading control with thrusters is necessary when a different heading than the natural weathervaning heading is wanted for operational reasons...

The paper documents operational challenges in controlling nutrient injection rates based on water injection volumetric fluctuations along with operator benefit from remote web based data and alarm monitoring. controller upstream oil...

.... The paper presents current developments aiming at reducing loading experienced by offshore wind turbines using advanced control strategies and LiDAR based long-distance wind measurements. In order to mitigate the wind loading, modern wind turbines indeed rely on control systems that define optimal blade...

... real time, but this proved feasible. The setup provides the best of both worlds: The model tests help to account for the hydrodynamic interactions correctly, while the onboard DP system ensures that all functionality in the control is identical to the actual operation. In addition, this setup allows...

Standard communication grade fiber cable is utilized. Unlike conventional methane detection systems currently employed, our system does...

... system consists of a number of power converter building blocks connected in series on both the on-shore station and the seabed stations. The dc-link current is controlled to be constant, and the dc-link voltage will vary according to the loading condition. This architecture renders simplified power...

... Abstract This paper summarizes key results of the development and verification for a subsea compact separation control system based upon a literature review, control system design, dynamic simulations, and an integrated system test. The compact separation system being considered is designed...

... There are many pressure related issues of concern in petroleum well production. Both high and low pressure conditions are indications of problems that must be addressed to maintain well safety and performance. A flexible and reliable control system for pressure monitoring provides a failsafe...
