Home Offshore Monitoring. The vibration activity monitor is a relatively simple hardware and software system designed to provide updated predictions of the fatigue-loading activity in the jacket major-member welds of offshore oil platforms.
Positioned on the platform cellar deck, the vibration recorder measures platform deck motion with two orthogonal accelerometers. These motions are processed in real-time to provide continuous records of the direction and frequency of platform motion.
The recorded data is combined with transfer functions from a finite element structural model, in order to predict and rank the fatigue activity in the joints. These predictions are used to verify the platform design fatigue analysis, to understand where unanticipated fatigue activity has occurred and to define the welds for underwater inspection.Offshore Environmental Effects Monitoring
This monitoring information will result in cost savings, maximized operating window, increased safety, minimized fatigue on critical elements, and generally improve the understanding of the platform behavior. With this data you can:.Revel chapter 5 quizlet sociology
The central data acquisition unit should have enough channels to record the accelerometers and several additional channels to record other sensors such as:. Request a Quote. Offshore Monitoring Systems.This means operators often fail to know when machine and process variables are off-spec, which risks asset failures and costly downtime.
Today, the Internet of Things IoT and next-gen connectivity bring enthralling opportunities for reliable and cost-effective offshore monitoring. Having said that, traditional communication solutions are either limited, expensive or cumbersome for connecting large numbers of disparate assets at offshore drilling platforms. Cellular connectivity is most likely absent in the middle of the ocean.
And, given the massive size and complex, dense structure of oil rigs, setting up mesh networks is often a difficult endeavor.
Due to its seamlessness and ubiquity, satellite connectivity has been the most common option for offshore wireless implementation. Yet, the sky-high costs mean that satellite networks mostly pertain to high-bandwidth voice and data transfer, alongside connection of few high-value, critical data points only. Needless to say, this is highly inefficient and error-prone, while exposing workers to significant field dangers and hazards.
Providing an inexpensive, low-bandwidth wireless link for small, low-computing devices, LPWAN is set to be the backbone of large-scale sensor networks to aggregate granular telemetry data from innumerable endpoints. Private LPWAN, in particular, allows companies to flexibly adapt network coverage to the unique requirement of isolated offshore sites. Data from distributed field sensors are aggregated at a local IoT base station through the LPWAN radio link, before being forwarded to an onshore centralized command center using the satellite connection.
With this architecture, companies can tap into a new host of asset, environmental and process data for a comprehensive picture of their running production. Smart sensors retrofitted on hundreds of disparate assets report critical operational variables that help unveil abnormal conditions preceding failures.
Offshore Wind Sensor Monitoring
This allows operators to timely dispatch staff for inspection and maintenance before severe breakdowns occur, to minimize production downtime and optimize asset uses. Distributed environmental sensors continuously check for the slightest presence of flammable gases and toxic vapors in the atmosphere. In the event of emergencies, on-premises alerts can be timely triggered for immediate counteraction to safeguard workers and prevent serious, irreversible catastrophes.

Likewise, critical infrastructure like watertight doors and ballast tanks can be monitored round-the-clock. Wireless sensors can identify suspicious movements at restricted areas and open doors across the rig to reinforce site security. Due to its asset-intensive and complex nature, the Oil and Gas sector is deemed to tremendously benefit from IoT and Big Data.
The ability to connect vast equipment and processes renders companies with unprecedented visibility and control over their operations. Particularly at offshore platforms, next-gen IoT connectivity is elevating remote monitoring and digitalization to the next level to improve efficiency and safety while minimizing human intervention.

The jacket-upending monitoring system is a case in point, which we developed and delivered in less than three months.
Seatools has a large experience base in the field of subsea pressure measurement. Pressure can be measured internally, such as in a submerged hydraulic system, as well as externally, for example to derive depth. Our highly accurate applications form an excellent basis for subsea monitoring and control systems, as is demonstrated by the strongly diverse subsea installation monitoring systems Seatools has delivered in the past.
Seatools has extensive experience with, and offers a wide range of sensors and monitoring systems for, subsea length, displacement i. For 1D underwater displacement measurement, Seatools offers the WLM Wire Length Measurement sensors as well as linear stroke sensors, which are both highly robust and accurate. In addition to the above-mentioned standardized sensors and systems, Seatools has shown its expertise in the integration of sensors, using alternative principles — such as acoustics e.
Doppler, USBL — to measure the position of submerged objects. Seatools offers a variety of solutions for level and volume measurement in subsea applications, such as for subsea compensators and reservoirs. In essence, two types of systems exist: point level measurement systems and continuous level measurement systems. These systems provide an alarm signal once a pre-specified fluid level e. Rather than measuring a single point, continuous level measurement solutions measure fluid levels across a range, producing a signal positively correlated to the actual fluid level.
Seatools is highly experienced in both inclination and angle measurement in offshore and subsea environments. This experience ranges from straightforward winch angular position measurement to inclination measurement of pontoons and large structures such as jackets during the jacket upending process. Depending on your specific application, a variety of field-proven, standardized subsea sensors can be applied, such as the rotation sensor range or the inclinometer sensor range.
In addition, Seatools has supplied a variety of custom-built inclination measurement systems over the years. The template leveling system, for example, allows for very efficient and accurate leveling operations of large structures. Also the wireless level measurement system has provided clients with unprecedented accuracy.
This knowledge base has been acquired first of all during the development of subsea DP systems, applied to many of our fall pipe ROVs. Thanks to these developments, an extensive library of motion sensor behavior including sensor-specific imperfections was developed, put to use during simulations reproducing sensor performance incl.Usps delivery map
Seatools delivers highly accurate force and torque monitoring and control systems for subsea equipment. Accurate force and torque measurement and control is of utmost importance to a wide range of subsea operations, for example to prevent wire overload in diamond wire saws.
For the Barracuda subsea diamond wire sawfor example, Seatools developed a highly accurate saw control system as part of the all-electric subsea drive system.
