Sevan Voyageur anchored in Nymo at the Eydehavn yard in Norway. NLI Engineering delivers over 20 large FPSO topside projectsNLI Engineering, a Norwegian industrial company, is involved in a number of breakthrough projects in the increasingly demanding oil & gas industry sector. The company is currently using AVEVA Plant as the engineering tool on several oil & gas projects. Two particularly interesting examples of these ongoing projects are a water treatment plant on the Goliat FPSO (Floating Production Storage and Off-loading), and the reconstruction of Sevan Voyageur.Magnus Feldt Industry Marketing ManagerAVEVANLI Engineering is part of the NLI Group, a Norwegian industrial group of companies with extensive experience of projects and developments within the oil & gas and industrial sectors. The group delivers complete solutions including engineering, fabrication, installation and commissioning in the oil & gas and onshore industries.When we visited NLI Engineering in Vear, 100km south-west of Oslo, we found the company extremely busy. NLI Engineering has grown rapidly, from 5 staff to over 90 during the last 5 years. As a result of a very high level of activity and several new projects, the company continues to expand.AVEVA PDMS used right from the start of a project'NLI Engineering is a market leader in engineering services for FPSO and platform topside design,' explains Jonas Fjeld Christensen, CAD Administrator, NLI Engineering. 'We have two engineering offices in Norway, and one in China. Many of our engineers have experience in shipbuilding and construction supervision in Norway and abroad, so we have unique fabrication expertise in all disciplines, and at all levels, at five fabrication sites in Norway and one in Poland.'With support and training provided from AVEVA's Oslo office, applications from the AVEVA Plant portfolio, including AVEVA PDMS, were implemented in April 2008. We started to use PDMS because of a specific demand from our customers in the oil & gas industry in Norway.'NLI Engineering uses PDMS throughout its projects, from first layout studies to the completion of detailed design. The equipment, piping and ductwork are all built in the PDMS model, from which all types of fabrication information are automatically generated, including piping isometrics, general arrangement drawings, weight reports, material take-offs, bills of materials, pipe support drawings, cable tray routings and ductwork layouts. Tekla Structures is used for the structural design, which is imported into the PDMS model via NLI Engineering's in-house developed interface.Engineering and fabrication work closely together'Engineers from the fabrication site visit the engineering office during the design phase for regular design review meetings,' Jonas Fjeld Christensen continues. 'These cross-discipline reviews enable us to detect potential design problems early on, before fabrication starts. Staff from the engineering office frequently visit the fabrication site during the construction phase. The PDMS 3D model is made available to the production engineers at the fabrication site, to support the building of the modules.First projects with PDMSNLI Engineering's first use of PDMS was for the Front-End Engineering and Design (FEED) of the generic topside process plant on the world's first Floating Liquefied Natural Gas (FLNG) production vessel. The scope of the work included structural and piping design, and specifications and modelling of the PDMS 3D model of the topside.30AVEVA World Magazine 2011|Issue 2
The FLNG vessel will process two million tons a year. This project, which is targeted for start-up in mid-2014, will liquefy gas from the onshore Elk and Antelope gas fields in Papua New Guinea. The vessel will be built by Samsung Heavy Industries in South Korea.'This project was soon followed by projects for the Goliat FPSO and the BP Valhall platform,' explains Jonas Fjeld Christensen. 'PDMS was used for the FEED design of the FPSO platform. Then, in late 2009, M-I EPCON AS awarded us the contract for the engineering, procurement, fabrication and installation work for a water treatment module for the BP Valhall platform in the Norwegian North Sea. The engineering work was performed with PDMS, and the water treatment module was delivered and installed on the platform in July 2010.'Another interesting early project in which NLI Engineering used PDMS was with Alstom Norway AS, in the development of cutting-edge CO2 capture technology for gas-fired power plants. The project included subcontract work on Alstom's demonstration plant for CO2 capture at The European CO2 Technology Centre, Mongstad. Statoil is in charge of this expansion, and NLI Engineering has provided the pipelines for the plant, the opening of which is planned for November 2011. The plant will be using Alstom's carbonate technology, chilled ammonia, to capture CO2 from fumes produced by the heating plant at Mongstad and from a processing plant (a cracker) at the nearby Mongstad refinery. It will be the largest demonstration plant of its kind, able to process fumes from both a gas-fired plant and a refinery.AVEVA World Magazine 2011|Issue 231Support for all engineering disciplines'One of the first impressions we had of PDMS was the impressive amount of information about the project that could be stored in the 3D model,' explains Jonas Fjeld Christensen. 'And the easy access you have to all the objects and their attributes. This was different from the earlier engineering systems we had used. Our experience of PDMS has been that it is very suitable for projects in the oil & gas and process industries, as it supports all our engineering disciplines.'Jonas Fjeld Christensen, CAD Administrator, NLI Engineering.
