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

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
