Control strategy for stabilizing the world's largest semi-submersible heavy transport vessel

Emerson’s level sensors and control technologies help maintain stability of huge FPSO transporter using sophisticated ballast control system.

Named Dockwise Vanguard, the new vessel is designed for heavy marine transport and offshore dry docking, enabling oil and gas operators to design and build larger and heavier offshore structures such as floating production storage and offloading (FPSO) vessels. Because of the Dockwise Vanguard’s loading capacity of up to 110,000 metric tons and its bowless design, it is now possible to fabricate these megastructures and load and transport them intact to remote offshore wells or production sites. This helps cut costs, lowers risks, improves schedule flexibility and reduces offshore man-hours required to get these enormous production units into operation.

Emerson supplies a comprehensive ballast control system, which is responsible for helping the Dockwise Vanguard submerge and rise with stability and integrity. It relies on tank gauging systems that provide highly accurate level measurements for load calculations as well as high level and overfill alarms. The system uses Emerson’s Smart Wireless technology to measure and transmit tank level data to the wheelhouse.

"Conditions in the offshore environment require ballast control that is also easy to operate and maintain and Emerson has proven the reliability of its marine tank management systems on a number of other Dockwise vessels."

The Dockwise Vanguard was awarded a 2012 Spotlight on New Technology Award by the Offshore Technology Conference (OTC) which recognizes innovations that are leading the industry into the future.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
