Myth vs. Reality – Use of ROVs in Subsea Drilling Operations

Myth vs. Reality – Use of ROVs in Subsea Drilling Operations

Supreme Integrated Technology, Inc. is proud to partner with many clients to deliver equipment necessary for subsea drilling operations. One of the interesting technologies we are able to assist with is underwater remotely operated vehicles (ROVs) which have replaced the need for human divers in many operations.

Myth: ROVs are not reliable for subsea drilling operations.

Reality: ROVs have proven to be extremely reliable for subsea drilling operations. They are equipped with advanced capabilities such as high-definition cameras and sophisticated manipulator arms, which allow them to carry out a wide range of tasks with precision and accuracy. In addition, ROVs can be remotely operated from the surface, which eliminates the risk of human divers needing to work in dangerous and harsh underwater environments.

Myth: ROVs are too expensive.

Reality: ROVs offer a number of benefits that can offset the cost. For example, they allow companies to drill in deeper waters, where traditional drilling methods are not possible. Additionally, the use of ROVs can improve the efficiency of drilling operations, as they can be operated around the clock and are not subject to the limitations and risks associated with using human divers.

Myth: ROVs are not as effective as human divers.

Reality: In many cases, ROVs are more effective than human divers for subsea drilling operations. ROVs are equipped with the following technologies:

High-Definition Cameras: show live video feeds to the operator on the surface. This allows the operator to see what the ROV is seeing in real-time and to make decisions based on that information.

Manipulator Arms: allow them to manipulate objects and carry out a wide range of tasks, such as retrieving samples, cutting cables, and installing subsea equipment.

Thrusters: deliver precise and efficient propulsion and maneuverability. The thrusters are designed to allow the ROV to move quickly and smoothly in any direction, which is essential for many subsea tasks.

Navigation Systems: provide precise position and orientation information. This is critical for tasks such as subsea survey and inspection, where accuracy is essential.

Communication Systems: allow the operator to control the ROV and receive real-time data and video feeds from the subsea environment.

Power Systems: power ROV’s various systems and components. This allows the ROV to operate for extended periods of time without needing to be recharged.

ROVs are critical for avoiding the limitations and risks associated with human divers, such as decompression sickness and other health risks associated with working in harsh underwater environments.

SIT has worked on various systems for ROVs including valve controls, deck controls and hydraulic power units. We specialize in tough applications and have the ability to design lightweight systems that can withstand harsh environments of saltwater and deepwater operations.

SIT & Wind Energy – Jacking Systems for Vessels Used in Wind Farm Installations

Supreme Integrated Technology and its predecessors have a long history of designing, manufacturing, and installing jacking systems used for hull elevation of self-elevating platforms otherwise known as liftboats. Liftboats have been historically used as movable work platforms for shallow water oil and gas drilling (commonly used in the Gulf of Mexico, North Sea, Persian Gulf, and Asia Pacific). Recently liftboats have found a new purpose, to develop clean energy resources as they are a key component for work of geotechnical investigation and installation of offshore wind projects.

SIT designed and delivered the jacking system for the Liftboat Jill in 2014 – which is now owned and operated by Falcon Global.  In 2019, Falcon Global agreed to a long term time charter to allow Fred. Olsen Windcarrier to utilize the Liftboat Jill in its fleet primarily for use in offshore wind projects.  In April 2020, Liftboat Jill was contracted by the Danish company Geo to support a vessel conducting an offshore borehole campaign the Danish North Sea.

Of this collaboration, Jens Brink Clausen, Department Director at Geo said: “We are looking forward to do the first geotechnical work on Thor for Energinet.dk this summer. Our new cooperation with Fred. Olsen Windcarrier will ensure a very safe and robust solution for the drilling operations.”

SIT’s jacking systems, recognized also as the “Hydraquip jacking system,” are known for being the smoothest in the industry, allowing crews to feel safe and secure during their stays. SIT designs and manufactures the completely integrated power system and provides custom designed drivetrains including brakes, motors, gear boxes, and pinions for rack-and-pinion movement between the liftboat legs and vessel hull.  SIT also designs and supplies the complete control system so the liftboat can easily lift and lower from the bridge of the vessel.

The Liftboat Jill has a 1325 metric ton jacking capacity per leg, operates in water depths up to 280 ft (85 m) and can accommodate up to 128 personnel plus 20 crew.  One of the largest, fastest liftboats that operated in the Gulf of Mexico, this vessel is a reliable and efficient method for assisting with offshore projects. Supreme Integrated Technology looks forward to more opportunities in the future where it can help deliver resources for vessels engaged in the exploration and implementation of alternative energy resources around the world.

Valve MAST (Maximum Allowable Stem Torque): Its Relevance and Use in Valve Automation

One of the most important criteria when performing calculations for sizing of automated and manually-operated valves is considering the valve’s MAST value. The MAST value is the Maximum Allowable Stem Torque, defined as the greatest torque to which a valve stem can be subjected to during operation without mechanical failure.

Historically, its relevance was somewhat reduced in the valve and actuation industry, especially when it came to actuator sizing. Even today, you may be hard-pressed to find it included in sizing procedures in any manufacturer’s standard catalogue since this information is usually considered proprietary to design. However, as assets age and failure history is established, this value’s importance and demand for accuracy have adopted a more influential role in actuator sizing today.

Failure to identify, select, and size inclusive of the MAST value usually results in a partial or full shearing of the valve stem causing anything from valve leakage to complete loss of control. In some cases, it is not necessarily shearing that occurs but rather deflection during operation. The cause of this deflection originates from the selected stem material being too soft to withstand the applied forces to the disc, ball, or plug. Unfortunately, this discrepancy yields a chronological accelerated wear of the sealing surfaces which ultimately gives way to premature leakage and accelerated valve failure. The valve, and its level of importance in the application, determine the severity of the failure’s outcome. It is important to understand that there is currently no regulation by API (American Petroleum Institute) that requires manufacturers to publish their MAST values or “raw” torque values, despite mutual agreement throughout the industry by valve experts and engineers that such information is essential to actuator sizing and lifetime valve performance.

“Raw” torque values refer to the valve torques that have not been inflated by a manufacturer’s internal safety factor (which is usually added to account for manufacturing tolerances). In most cases this all boils down to the repeatability of each manufacturer’s manufacturing process and various checkpoints for quality control. Most manufacturers have very predictable manufacturing tolerances; however, they elect to omit the safety factor from published torque data. This exclusion is the primary reason why MAST values are exceeded. Excessive torque at the stem when sizing actuators will create a need to consider changing stem material. Specifying a higher yield stem material will prevent deflection or in the worst-case complete valve failure due to sheering. There are many different factors that can affect stem material selection and design in valves. Whether butterfly valves, ball valves, or plug valves, the customer or EPC provides the application conditions and, in turn, the valve manufacturer or automation supplier recommends a product that meets the provided conditions. Factors that may affect stem material selection are pressure class, process media, environmental factors, and client classification requirements.

Since valve manufacturers and distributors usually stock only the most popular valves to reduce inventory costs and maintain a high level of turnover, valves with uncommon body, disc, and stem materials are typically only produced on a machine-to-order basis. Therefore, delivery of these products can range anywhere from 26-48 weeks with cost variances of four to five times the average. If the manufacturer does not state the provided values are raw, it is imperative for one to seek clarification for this added multiplier. In short, ask questions! Ensuring that this base torque value for the valve excludes a safety factor is of the utmost importance for the following reasons: 1) preventing a multiplication of safety factors and oversizing of the actuator and 2) forcing an unnecessary upgrade to the stem and disc material.

Some of the most common stem materials are listed below in increasing order in terms of MAST as well as cost impact:

  • 316/316L SS
  • 17-4 PH SS
  • Monel K-500
  • Inconel 718

It is crucial to consider safety factors from both the client-driven requirements and the built-in margin from the manufacturer. In doing so there will be instances where combinations of the above must be utilized. Even when MAST values have been identified, failure to confirm the manufacturer’s published numbers can drive up costs and lead times exponentially due to misinterpreted data. Correctly interpreting manufacturer’s data, identifying red flags, partnering with experienced automation groups, and having strong relationships with valve suppliers are all keys to ensuring that an automated valve assembly’s configuration is mechanically correct and cost-effective.
