Vega has combined many years of experience in offshore applications to produce process instrumentation for a wide variety of applications in oil and gas production. Its sensors measure level and pressure, helping to make operations safer for crew, equipment and the environment.
A stable, horizontal orientation of the drilling and extracting facilities in the water is indispensable for the safety of the crew and the equipment. Oil and gas platforms or FPSO (floating, production, storage and offloading) ships carrying several thousand tons of weight must maintain an exact balance. Load shifts can occur on board due to a variety of reasons, including external effects from wind and waves. A shift in load balance cannot be allowed to influence the stability of the system and so measurement instrumentation is used to control such changes.
The floating platform is stabilised by ballast tanks filled mainly with seawater. By filling or emptying these tanks, different mass distributions on the platform can be compensated. Accurate, seawater resistant level measuring systems are indispensable for trouble free operation of the ballast system.
Vega’s hydrostatic pressure transmitter VegaWell 52 is ideal for use in ballast tanks thanks to its robust mechanical construction. The high overload resistance of the ceramic measuring cell makes it practically immune to pressure shocks, which means its measurement reliability is substantially increased. A corrosion resistant duplex coating is used in addition to PUR cable, which makes the components highly resistant to seawater and guarantees a long service life.
In addition to using a pressure gauge in the ballast tank to maintain balance, Vega’s vibrating level switch VegaSwing 61 provides reliable leak detection in the pontoon. It can be installed in any position and works reliably, unaffected by pressure, temperature, foam, viscosity and bubbles. Safety installations require regular tests – in the case of VegaSwing 61, the test can be carried out easily from the control room.
Meeting the challenges of tank obstructions interfering with radar
Level Measurement & Control
One of the most challenging applications for non-contacting radar level transmitters is measuring level in tanks with internal obstructions, such as agitators, heating coils, pipes, ladders or baffles. Rosemount non-contacting radar level transmitters from Emerson feature an advanced solution that enables accurate and reliable level measurements in tanks with obstructions.
