Grenland Group Maximizes Offshore Yield with SmartPlant®

Grenland Group provides design and engineering for new drill ships and semi-submersibles, as well as modifications of older semisubmersibles, shuttle tankers, and other offshore and marine floaters. SmartPlant® products helped the Norwegian company during a complex offshore drilling project in the North Sea.

The Challenge

For the Low Pressure Modification Project at the Oseberg field in the Norwegian part of the North Sea, the Grenland Group had to deliver all engineering and manufacturing information.

The project involved two offshore platforms connected by a bridge. Owned and operated by Norwegian oil and gas company StatoilHydro, the enormous and complex Oseberg field modification effort required 170,000 engineering labor hours, and the project deadline was extremely tight.

The integration of disparate data - including manual drawing information, existing 3D models converted from PDMS, use of new 3D laser scanning technology, and new modeling data - added to the complexity.

Grenland faced extreme difficulty when it routinely used a wide variety of design engineering applications. The various applications did not work together, compounding workflow problems. As the company grew, design engineering system activities became increasingly harder to support and more expensive to manage.

The Solution

The timeframe for StatoilHydro’s project completion was critical, placing a heavy burden on Grenland to automate the information flow and avoid delays. The project’s financial success, both for client and owner operator, depended on this.

"SmartPlant® Enterprise is essential to achieving our goal," said Terje Ørbeck, CAD manager and 3D coordinator at Grenland Group. "To put it mildly, there was a lot of very different engineering software in use at Grenland."

Information had to be integrated from general drafting systems, like AutoCAD and MicroStation 2D drawings, and from 3D modeling, such as PDS, PlantSpace, and PDMS. Standardization was necessary to minimize costs and maximize resources.

"SmartPlant Enterprise met and even exceeded our expectations," Ørbeck said.

Around 20 designers in the Oseberg project used the system for 3D modeling, structural design, piping, and equipment design, and raceway design. Layout and structural fabrication drawings, piping isometrics and spools were all extracted from the system. Seven process engineers and five instrument engineers performed design work using SmartPlant Enterprise.

The use of SmartPlant Foundation as the main design engineering data source for the project was further extended to also include publishing of drawings like layout, manufacturing drawings for structural design, piping isometrics, and P&IDs. 

"Intelligent tools on a common platform are feeding the main information into a single data source," Ørbeck said. "That means you get control of your design and can achieve your project goal on time and within budget."
