Study on Effect of Aerodynamic Sound Hardening for Wear of Coated Carbide Metal Plates
Authors: Sheleg V. K. , Jigalov A. N. , Bogdan D. D. 
Published: August 2020

To increase the durability of metal-cutting carbide plates operating during in harsh technological conditions with impact load, an aerodynamic sound hardening method has been developed that can increase a life of carbide tools up to 3.7 times with a small added cost. The wear of plates hardened by the aerodynamic sound method, after 100 min of cutting, is 1.12–1.7 times less than their un-strengthened analogues. A coating on metal carbide plates does not have a prevailing value when a tool is working with impact loads. While working with impact loads viscosity of an internal plate structure occurs the greatest influence on increasing resistance. For metal-cutting carbide plates during interrupted cutting with significant impact loads, a method of aerodynamic sound hardening is more effective than a coating method, not only in terms of tool performance, but also in the cost of completion itself. Empirical dependences of wear on the rear surface of carbide plates hardened by a aerodynamic sound method and plates with PVD coatings have been obtained in the form of approximation by polynomials of the 5thand 2nddegrees, which are convenient to use in a production environment. It has been revealed the higher carbide plate strength in bending leads to less influence of the method of aerodynamic sound hardening on the increase in wear resistance. So, taking into account the fact that for ВК8-base the ultimate bending strength is 1666 MPa, and for T5K10 it is 1421 MPa, wear reduction after hardening by the aerodynamic sound method for ВП3115-plates with ВК base is 11.5 %, while for ВП3225 – plates with ТК-base – 27.1 %.

It has been substantiated that in order to control the process of forming flat surfaces while using a free grinding method it is advisable to choose such machine setup parameters as a tool diameter and its rotation frequency, an amplitude of the reciprocating movement of the part along the tool (or vice versa) and frequency of this movement, as well as the value of the working force. Mathematical modeling of patterns for abrasive processing of flat surfaces in the conditions of free grinding on lever machines has been carried out in the paper. A formula has been obtained for calculating a sliding speed at selected reference points on the surface to be treated while taking into account the pressure in their vicinity. Patterns of the part operation have been determined, for which a correct plate is used in the proposed axicon production technology with due account of the combination and size of the selected setup parameters for processing equipment. Self-organization of the processing process has been substantiated while using a free grinding method. Sensitivity of a kinematic response to a change in processing modes and efficiency of these modes in terms of process performance have been determined in the paper. It has been noted that an increase in a tool diameter, as one of the effective adjustment parameters for controlling the shaping process, is difficult to implement in practice, since this requires replacement of tools, each of which must be pre-configured while using a special rather time-consuming technique. The paper reveals that with an increase in the tool rotation frequency and an amplitude of its oscillatory movements, there is an increased removal of material on the periphery of the surface being machined, and with an increase in vibrational movements, on the contrary, the central zone of the part is more intensively activated.

Currently, due to the increase in the average speed of vehicles to ensure their visibility, the luminous intensity of their lightning equipment is constantly increasing, that can lead to blindness of other road users, especially at night. On the other hand, if you do not increase the luminous intensity if lanterns, a vehicle will not be noticeable in difficult road conditions (fog, rain, dust) and it can cause an accident. To eliminate this contradiction, a fundamentally new modular design of the adaptive rear combined vehicle light with non-replaceable light sources based on single powerful light emitting diodes and effective secondary optics of large diameter has been developed in the paper. The design provides for the use of an integrated microcontroller to control luminous intensity of its lights, depending on the conditions of external illumination, braking dynamics of a car and surface condition of a lamp diffuser with the possibility of transmitting data via a CAN-bus. Thanks to the built-in microcontroller, the developed flashlight is suitable for installation on vehicles without an on-board computer. These properties allow the flashlight to ensure visibility of a vehicle, and to avoid blinding the remaining road users. The design of the adaptive lamp is small in thickness (up to 40 mm), high luminous efficiency (at least 85 %) and reliability. The conducted lightning tests have shown that the developed lamp fully complies with UN Regulation No 6, 7, 23, 38, 48. The design has been compared with existing analogues of foreign production, which showed that such a lamp consumes less energy (30 %) and has a lower probability of failure due to the use of high-power LEDs used as a light source.
Guest Editorial: A Net-Zero Future Full of Opportunities for a New North Sea
Authors: Cohen Colette 
Published: August 2020

Six months ago, if asked what the biggest challenge was facing our industry and perhaps the world, I would have said, “The transition to a low-carbon/net-zero world.”
Who knew that the biggest threat would actually be an invisible, but devastatingly brutal, enemy? And what impact will that have on our futures? Not only on our commitment to net zero but to our industry’s survival and to the industrialized world we know.
There will be many views, but as I lead a technology organization, I believe we can use this “industrial reset” to chart a new course for our industry and hopefully for our planet. This is a time for us to capitalize on the amazing collaboration we have seen locally, regionally, and globally, as society has pulled together to fight COVID-19.
Can we not put this can-do attitude into action on our biggest global challenges and work together to find a solution? While many of the changes required will be either behavioral or regulatory, a number will be technology-led - and that is where technical industries can have the biggest positive impact in the coming years.
As I look around the world, I can already see countries launching major public/private initiatives to grasp the low-carbon agenda. These are partnerships where businesses innovate and collaborate, with government backing, to create powerful collectives driving both decarbonization and economic growth.
I strongly believe this is the route we should take in the UK - forming deep collaborations to capitalize on our expertise and collective know-how to transform the North Sea into a low-carbon powerhouse.
Progress Made So Far
The good news is, we have already begun.
The UK Continental Shelf has already committed to a net-zero future in the industry’s Roadmap 2035, introduced by Oil and Gas UK.
The Oil & Gas Technology Centre (OGTC) has been supporting the industry with more than £150 million co-invested in emerging technologies in the past 3 years. And in 2019, we opened a center dedicated to the development and deployment of net-zero technologies.
We have worked closely with industry to develop a technology vision and road-map that focuses on three big goals:
Reducing emissions from existing operations
Developing new technologies - including carbon capture, utilization, and storage (CCUS) and also hydrogen - to unlock the potential of our assets and expertise
Transforming to a net-zero industry in the longer term
No one imagines this will happen overnight - the Committee on Climate Change, for example, recognizes that oil and gas production will continue to 2050 and beyond - but at the same time, it predicts massive growth in other sectors, most notably in offshore wind, blue hydrogen, and CCUS.
The current confluence of global challenges, therefore, offers a huge opportunity for the industry to set itself new goals on efficiency, performance, carbon footprint, and the transition to a net-zero future.
AI Meets HMI: Next-Gen Robots Take on the Tough Tasks To Reduce Risks on Rigs
Authors: Flowers Lynnmarie P. 
Published: August 2020

Often located hundreds of miles away from land, offshore oil and gas platforms pose challenges with their unsheltered maritime environment, heavy weather, and risk of explosive, toxic, and corrosive atmospheres - with limited resources.
Sounds like conditions are ripe for robots on rigs.
In 14 years at Equinor, robotics researcher Anders Røyrøy has explored the application of robots in jobs that he describes as “dangerous, dirty, distant, or dull,” where use of a robot can serve to mitigate or eliminate safety risks for humans.
One of the highest priorities for robotic development and deployment, in view of their impact on inspection and maintenance routines, are remote operators for onshore and offshore platforms.
Failures in such harsh environments could jeopardize the lives of human operators, the environment, and process equipment. Semi- or unmanned operations can yield significant reductions in the risk of personnel exposure to dangerous chemicals. And in this age of social distancing, robots can be essential in providing contactless support.
Traditionally, bases of design have been focused on improving the safety of existing manned installations sites (brownfield) - those not designed with robots in mind - during potentially dangerous operations. Although it is possible to enhance safety, efficiency, and production availability on a brownfield site, French supermajor Total E&P is challenging that approach by developing remote or unmanned robotic solutions for specific functions on greenfield sites - that is, on automated, unmanned platforms designed to accommodate newly developed technology.
Generally unattended/unmanned installations are those that are visited only every 2 to 3 months. However, if the duration is pushed to one visit per year to perform annual maintenance tasks, it is possible to reduce the complexity of the platforms by removing equipment meant for human presence on site. There are several safety and cost advantages for operating remote production sites using robotics in place of crews.
For example, without the presence of personnel on site, an operator can often remove human-related systems such as living quarters, catering, evacuation boats, and staff transportation to and from its installation, along with inherent risks and high costs. Fewer boats, helicopters, and less road transportation leads to reduced operating costs and CO2 emissions. On such unmanned sites, Total is considering mobile, multipurpose, and ground robots that are ATEX-compliant (safe to operate in potentially explosive environments) and suitable for harsh and dangerous conditions.
A fully autonomous robot can gain information about the environment, move around and work for an extended period without human intervention, avoid harmful situations (unless those are part of its design specifications), and learn new ways to execute its tasks while adapting to changing surroundings.
Use of Low-ECD Synthetic-Based Mud During Topdrive Failure
Authors: Kratzer Matthew 
Published: August 2020

While drilling in deepwater Gulf of Mexico, a topdrive failure forced the shutdown of all drilling operations for the rig operator and lasted for 114 hours (almost 5 days). At the time of the failure, the equivalent static density (ESD) was 11.36 ppg and the equivalent circulating density (ECD) was 11.5 ppg. The rate of penetration (ROP) was 100 ft/hr.
Troubleshooting
It was recommended that there be no utilization of the pumps while drilling was stopped, to reduce the chance of packing off the annulus with cuttings until the rotating and reciprocating could continue. During this time, a 100-psi backpressure was maintained using the managed-pressure drilling system. Kronos low-ECD synthetic-based mud (SBM) at a weight of 10.9 ppg was utilized during this event.
During troubleshooting and repair work, a 1,500-bbl 11.4-ppg riser cap was spotted. Following the repair of the topdrive, a malfunctioning packer had to be replaced, causing additional delays.
After the packer was set and the blowout preventers tested, the 11.4 ppg riser cap was displaced and subsequently replaced with 10.9-ppg low-ECD mud. The Kronos system was designed and maintained to have adequate suspension properties to maintain wellbore integrity without sag during unexpected downtime, even with cuttings left in the hole. The rig continued to trip into the hole to 9,800 ft. At that time, a bottom-up was circulated and a maximum of 575 units of gas was circulated out.
Drilling then continued using a base oil and premix for dilution. The lost circulation material in the background continued to be blended into the dilution products being used at the time. During the drilling from 11,636 to 12,845 ft, the decision was made to increase the mud weight to 11.15 ppg.
When the drilling continued from 12,845 to 13,234 ft, formation water was detected from the mud check entering the mud system.
The system was treated to minimize the damage caused by formation water and maintain the properties sought by the operator. To assist in maintaining the desired weight and to prevent low-gravity solids from impacting the mud weight, two shakers were screened up to API Standard 120. At roughly the same time, the mud weight was increased to 11.2 ppg and then to 11.4 ppg.
While continuing to drill, one of the engines that provided power to the mud pumps broke down, reducing the flow rate required to clean the hole. A cement unit was added to the pump to replace much of the volume lost with the broken mud pump.
At 13,155 ft, the decision was made to call this current interval at total depth. The back-reaming process also started at that time. To assist with the hole cleaning, a high-viscosity sweep was blended and circulated. An additional high-viscosity sweep was blended and circulated, the second time at 9,058 ft.
With continued back reaming through some tight spots to 7,272 ft, operators decided to wash back down 7,938 ft and pump one more high-viscosity sweep. Once the hole was clean, a flow check was performed and operators began to pull out of the hole.
