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.

32AVEVA World Magazine 2011|Issue 2Goliat FPSO water treatment plant projectNLI Engineering's first project with PDMS 12, which was implemented in January this year, is the ongoing detail engineering project for the water treatment plant on the Goliat FPSO platform. They believe that it is thanks to the successful implementation and delivery of their previous project, (an EPCON CFU skid for the BP Valhall platform), that M-I EPCON awarded them this contract for the complete detail engineering of two skids, in February this year. The project is already well under way.The FPSO chosen for the Goliat field is a fully-winterised, Sevan 1000 cylindrical floater FPSO design, capable of handling the harsh demands at the Goliat field in the Barents Sea. The Goliat FPSO will have a daily production capacity of 110,000 barrels of oil and 4 million cubic metres of gas per day, as well as a storage capacity of 1 million barrels of oil. Production on the Goliat oil field is scheduled to start in 2013. The Goliat FPSO will be built at Hyundai Heavy Industries in South Korea.The cylindrical hull of the FPSO enables the platform to be anchored permanently, regardless of changing weather conditions. In addition, the platform has considerable storage capacity, the hull is easily constructed, and it can take on large cargoes. 'PDMS 12 has given us a more user-friendly interface. We now find it easier to define the component catalogues and specifications, and to search for system information,' says Jonas Fjeld Christensen.Reconstruction of FPSO Sevan VoyageurIn December 2010, Sevan Marine awarded NLI Engineering a major contract related to the reconstruction of Sevan Voyageur. The job will mainly involve engineering related to the topside facility. Sevan Marine has decided that PDMS will be the engineering tool for this reconstruction project even though NLI Engineering used Bentley PlantSpace in the original design of the topside, in 2007. The existing 3D model was successfully converted into PDMS via the AVEVA Implant interface and a conversion program developed in house. Where direct model translation was not appropriate, a combination of 3D laser scanning and remodelling was carried out with very good results.The FPSO left the Shelley field, in the UK sector of the North Sea, in August 2010 and is currently anchored in Nymo at the Eydehavn yard in Norway, where the rebuilding will take place. The FPSO will leave for the Huntington field, also in the North Sea, in the third quarter of 2011; production is planned for the first quarter of 2012.Mongstad SMIL - an extensive onshore project 'PDMS has also been used for onshore projects,' says Jonas Fjeld Christensen. 'In autumn 2008, StatoilHydro awarded us a major contract for mechanical, piping and electrical work on the SMIL project at the Mongstad refinery (Statoil Mongstad Miljøinvesteringer).' 'We have built up a library of modelled PDMS equipment. By reusing these, we can rapidly create conceptual models for new projects and give clients an early, very detailed view of their project...'AVEVA PDMS model of one hydro cyclone skid for the water treatment plant on the Goliat FPSO.
