Tatweer Petroleum adopted the best GIS practices when implementing Tatweer's Spatial Data Infrastructure and utilizing Unmanned Aerial Vehicles (UAV) for day-to-day Operations in the Bahrain Oil Field. The initial milestone of the project was to have a detailed geospatial survey of the entire Bahrain Field, which was completed and introduced as the first "As-Built Geo-Spatial Map" of the Bahrain Field since the first oil well drilled in 1932. This allowed us to develop and deliver reliable GIS solution that eliminated conflicts and overlaps between projects, facilitating user acceptance. This led to the introduction of the concept of Spatial Data Infrastructure at an organizational level, which empowered the company with open access to high precision and up-to-date GIS services. Following the SDI project and As-Built GeoSpatial Map, the GIS team is leading the initiative in utilizing Unmanned Aerial Vehicles (UAV), also known as Drones, to address the unique needs of the daily operations by providing safe, efficient, and cost-effective maintenance and inspection solution.

Middle Eastern countries have the most complex and extensive oil and gas pipeline network in the world and are expected to have a total length of 24066.9km of pipelines by 2022. Routine inspection and active maintenance of these structures thus have high priority in the oil and gas operations. Pigging, the commonly used internal inspection method is expensive and the need for pre-installation procedures for flawless pig operations makes it time-consuming. The external inspection is currently done manually by a group of operators who either drives or walks over the buried pipeline structures. The visual/sensor data collected using various handheld devices are then analyzed manually to identify/locate the possible anomalies. The accuracy of data collected and their analysis highly depends upon the experience of the operators. Also, the extreme environmental conditions like high temperature and uneven terrain make the manual inspection a tedious task. The challenges in the current manual inspection methods can be tackled by using a robotic platform equipped with various sensors that can detect, navigate and tag the buried oil and gas pipelines.
In UAE, the oil and gas pipelines are mostly buried under a berm, a raised trapezoidal structure made up of sand over the buried pipeline structure. The pipelines are buried under the berm either as (i) single pipeline buried in the middle of the berm or as (ii) two pipelines buried on the two edges of the berm. To conduct any external inspection of buried pipelines using a robotic platform, the accurate location of the buried pipeline has to be known beforehand. The proposed Autonomous Robotic Inspection System (ARIS) should have the capability to precisely locate the buried pipeline structure and navigate along with these structures without any fail/skid. A novel hierarchical controller based on a pipe-locator and ultrasonic sensor data is developed for ARIS for detection and navigation over the buried pipeline structures. The hierarchical controller consists of two modules: (i) pipe-locator based tracking controller, that allows the vehicle to autonomously navigate over the buried pipeline and (ii) a sonar-based anti-topple controller which provides an extra layer of protection for vehicle navigation under extreme conditions. An experimental setup, similar to the real buried pipeline condition was built in a lab environment. The autonomous tracking performance of ARIS was tested under various buried pipeline laying conditions. The results obtained show the ability of ARIS to track and navigate along the buried pipeline even in extreme conditions without any fall/skid.
The scope of this paper is to present a new and innovative technology to enhance the performance of subsea installation and construction activities while reducing the risk for both human life and the environment. The conventional method of conducting subsea installation in diver-accessible areas is usually by the use of saturation diving systems and teams. This poses a significant operational risk on the lives of the team, the environment, and the subsea assets in the area, along with also having operational limitations. This paper presents a technology that reduces this risk and enhances subsea installation activities altogether.
The technology presented is an intelligent manipulator that can be installed on Remotely-Operated Vehicles (ROVs). The system relies on artificial intelligence, the geometry of machine making, power, and accuracy to enhance subsea installation operations. Through the use of 3D point cloud technology, the system is able to give accurate views and measurements of the surrounding environment, allowing for accurate path determination and decision making.
The result of the technology is that the ROV manipulator is able to mimic human divers’ mental and physical abilities in different modes of action during subsea installation operations, especially in hazardous environments. This enables such operations to be performed faster and in a more cost-effective manner. Moreover, a key result of the use of this technology is eliminating the huge risk suffered by human divers in hazardous saturation diving environment.
With the use of this technology, the industry would be able to utilize ROVs to conduct diver-less subsea installation activities in a safer, more efficient, and more cost-effective manner than by using saturation diving systems and teams.

Early studies indicate a large potential of savings in rig time and elimination of manual operations on the drill floor, when introducing robotic drill-floor equipment on the drill floor. Robots can carry out pipe, casing and tool handling tasks in a safe, fast, consistent and precise manner.
For obtaining a digitalized, fully automated drilling operation, electric robotic equipment is a key enabling technology.
Since 2016, Eni has been directly involved, together with Canrig Robotics, in the technology development process for the robotic drill floor, being part of two Joint Industry Projects (JIPs) in Norway, named "Offshore Pilot of Drill Floor Robot" and "Demonstration of Automated Drilling Process Control". The aim of such projects is to install and test robotic equipment on rigs and to demonstrate the full automation of drilling operations through the integration with an advanced control system.
A fully robotic drill floor requires state-of-the-art technological and industrial level innovation, which forms a basis for performing drilling & completion operations safely, reliably and consistently.
This paper describes the results of a preliminary feasibility study performed by Eni in collaboration with Canrig Robotics concerning the installation of such equipment on two different rig designs, three land rigs and two drill ships, in order to find the best candidate(s). The analysis contains data collection, operational descriptions, modification and installation works, value propositions and business cases.
The value proposition from using robotic equipment includes faster tripping due to consistent and seamless handling. A high number of manual operations can be saved by robotic handling of subs, pup joints, safety clamps etc. Stand-building can be made fully automated and can take place in parallel to e.g. drilling in the well center.
Preliminary results show a significant potential improvement on KPIs, with an estimated time saving of 20 to 60 days per rig yearly. At the same time, HSE issues are widely mitigated, since operations can be performed effectively and consistently by robots, thus removing people from harm's way on the drill floor.
Normally Unattended Installations with presence of people on site only once per year (NUI-1Y) for maintenance campaigns is the ultimate aim of unmanned concepts and a new frontier for cost reduction. Ground robotics is one enabler of this goal. This new technology is in its infancy and still requires technological and organizational advancements to be readily accepted and supported by the industry.
Total fully supports the unmanned concept and has been involved for several years in the development of autonomous ground robots capable of working in potentially hazardous environments. Adopting ground robots in our operations is not only a matter of Technology Readiness Level but also requires expertise on how to use this new technology. Accordingly, the Total roadmap for robotics development focuses on three key areas:
This presentation gives an overview of the Total roadmap on robotics, sharing results of the latest developments and how robots are being integrated in our operating philosophies.
Progress in the digital area has been quite significant in the past few years in terms of data monitoring, remote collaborative work, telecommunications and robotics to the point that disruptive ways to operate and to design surface installations can now be envisioned with HSE benefits and substantial cost reductions without compromising production efficiency. Normally Unattended Installations with presence of people on site only once a year (NUI-1Y) for maintenance campaigns is the ultimate aim of unmanned concepts and a new frontier for cost reduction. This approach is particularly relevant for remote production sites where operations usually require a continuous presence of a large crew and heavy logistical means. Although, this concept seems very challenging, it is in fact a natural extension of what has been applied with success on subsea developments starting over twenty years ago where wells, valves, separators, pumps and now compressors have been remotely operated from a host facility, together with the occasional assistance of Remote Operated Vehicles. A NUI-1Y development, in its philosophy, is very similar to a subsea architecture that would be applied to a surface installation.
Based on the geophysical survey results, some part of the pipeline were found in free spans conditions. Interpretation from the geophysical survey shows that there were at least 181 free spans area along the pipeline with the length up to 200m and some of the pipeline was shown with span almost 3m above seabed. The ROV survey was then deployed to verify the free spans area and to check the other findings from the previous geophysical survey
Verification of freespan was conducted by setting up coordinates of the suspected area on the navigation software and ROV will start its investigation from the beginning of each free span to the end of it. Dual head scanning profilers, visual cameras which were installed on each side of the ROV and in front of vehicle were used to record pipeline condition along the suspected location. Position and depth of the ROV was overlaid to the video recording and the profile of seabed and pipeline along the inspected area were recorded in the navigation software
Information derived from the ROV inspection will then compared to the geophysical survey result and the final freespan condition were confirmed and results are tabulated for further rectification if required. Generally, there were 181 freespans locations inspected by ROV. Results of freespan from Freespan #1 at KP 3.638 to Freespan #181 at KP 233.978 are listed. There are some miss leading geophysical interpretation for the sample taken at KP 101.108 to KP 101.281, where from the geophysical survey was reported that the free span was found 150.1m but from the ROV visual inspection was found that the pipeline was set on seabed at some points with a maximum distance not more than 35m. Based on the ROV visual inspection, there were 29 freespans were found more than Maximum Allowable Span (MAS)
East Java Gas Pipeline Pipeline (EJGP) is the longest offshore gas pipeline in Indoensia. It transports gas receiving from Central Processing Plant on Pagerungan Island in Kangean Islands through the Madura Strait and onshore via Porong Sidoarjo to Surabaya with the total length of offshore part is 368km. The ROV is the first to be used to inspect this offshore gas pipeline.
Nowadays, across the Energy Industry, there is no longer any discussion on the ‘Return of Investment’ for using drones for specific use cases such as Asset Integrity Inspections.
Given the time saving, the amount of data gathered, the better use of resources and worker safety benefits, using drones for several fields of application is a ‘no brainer’ for Eni.
In the last years Eni interest in using drones raised, paying now more and more attention to new fields of application such as HSE, Security, Seismic and Logistics in order to support several needs.
New Hardware and Software allows performing new types of operations as listed below, but not limited to:
Beyond Visual Line Of Sight (BVLOS) operations. Fully autonomous operations. Light Material transport Long range pipeline surveillance Emissions detection

In light of above, Eni looks to use drones in the workplace just like any other ‘tool’, don't just think of drones in terms of what we see today but think about tomorrow with interest on combination between UAS and Artificial Intelligence and UAS and IOT.
The implementation of UAS operations to several fields of application and in autonomous manner can really change the way to operate in O&G industry. This will facilitate not only operations at height but also operations offshore and in remote areas, with an improvement of safety for both operators and assets, reducing time and costs.

While leading companies in the manufacturing industry are doing their best to implement smart factories along with the wave of the Fourth Industrial Revolution, shipbuilding companies still seem to be a bit distant from the smart factories, due to the characteristics of the industry. In this study, smart shipbuilding platform is defined by studying the necessary elements for realizing smart shipyard in shipbuilding industry, and a forming shop is presented as an example to which the smart shipyard platform is realized and applied. To this end, the purpose of implementing the smart shipyard is discussed first and then the factors necessary to achieve the purpose are identified. These elements are grouped together into one system with the computational shipyard dynamics to define the smart shipyard platform. The platform is then applied to an actual factory of a shipyard to verify its effectiveness.
