This study develops an event-triggered controller for the ROV attitude system. First, the dynamic modeling of ROV attitude control is performed. The three-dimensional dynamic equation for ROV attitude control is obtained by decoupling each degree of freedom, and the model for the ROV attitude stability control system is obtained by taking into account the influence of ROV hydrodynamics, ship movement, and umbilical cable vortex-induced vibration. The ROV attitude stability control controller is designed by using backstepping control and sliding mode control, the event trigger mechanism is added to optimize its control output, and the Volterra adaptive multi-step prediction algorithm is designed to predict the ship sinking time series in advance, and the condition parameters are provided for the event trigger mechanism in the AHC controller to improve the positioning accuracy of the attitude stability axial subsystem (AHC). The simulation findings demonstrate that the control strategy and prediction algorithm developed in this study can accomplish the control task and have a strong anti-interference ability by establishing varying degrees of sea conditions and advanced forecast time for simulation tests. Additionally, the event trigger mechanism optimizes the control law, better utilizes the output control signal's channel, and prevents the control output from acting improperly, all of which can reduce network bandwidth use.

The diesel generators are usually used for supplying the electrical demand of the semi-submersible oil drilling rigs. The specific fuel consumption (SFC) of each diesel engine changes nonlinearly with respect to its power product.Hence, this paper presents an economic fuel dispatch model for diesel engines powered oil rig platforms using the cubic spline interpolation curve fitting of the SFC-power non-linear dependence. Moreover, the total fuel consumption of the diesel generators significantly reduces by shifting a partial part of the electricity demand of the offshore drilling rigs from on-peak time intervals to off-peak periods. In addition, battery energy storage contributes to the load curve smoothing strategy. A mixed-integer non-linear programming problem is developed under generalized algebraic mathematical modeling system to find the optimum fuel consumption and power generation schedules of the diesel producers, the value of demand increase/decrease, and the charge/discharge pattern of the battery at each operating time interval.

Purpose Every year, hundreds of people have died and thousands have been injured because of insufficient management of well control at oil and gas drilling and production sites. Major causes which have been reported in previous studies included uncontrollable blowouts and failure of blowout preventers because of insufficient safety practices. These onshore and offshore blowout disasters not only harm the work force but also critically affect the environment and marine life. In this research paper, a detailed quantitative survey and qualitative risk assessments (RA) have been carried out for assessing the potentially hazardous activities associated with well control along with their appropriate controls and risk reduction factors and mitigating measures in Middle East and south East Asian countries. Design/methodology/approach The sequential explanatory research design has been adopted in this study. Whereas, descriptive statistical approach has been used for the quantitative data analysis of this study. While, in-depth interview approach has been used for qualitative data collection. Similarly, what-if analysis method has been adopted in this study for the identification of effective safety and health risk mitigating factors because it provides in-depth information from health and safety environment experts. Findings The cumulative quantitative results based on the response from Saudi Arabian drilling industry have indicated that the well control operation is highly hazardous then Malaysian and Pakistani oil and gas industries. Likewise, findings from what-if analysis approach demonstrate that the drilling crewmembers have repetitively faced life threatening hazards which occur (safety and chemical) during well control onshore and offshore operation because of oil base mud, confined space at site, pinch points and falling during working on blow out preventers. According to the overall result, respondents have highly recommended engineering and administrative hazard controlling factors as most suitable for the elimination of safety and chemical hazards during well control activities. Practical implications Besides, the developed methodological framework for the identification of suitable hazard controls can also be effectively used for potential hazards reorganization and identification of suitable hazard controls for other drilling and production industries and regions for accident prevention and safety and health management. Originality/value This is a first comparative research study which has been carried out in Malaysian, Saudi Arabian and Pakistani onshore and offshore oil and gas industries for well control health and safety management and reorganization of most effective hazards mitigating factors at drilling sites.
