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.

AVEVA World Magazine 2011|Issue 233The SMIL project is a cooperative project involving several NLI companies and making use of the whole of the group's broad knowledge and competence. Project management personnel are provided by NLI's engineering companies. The contract represents the largest single order ever awarded to NLI.The purpose of the SMIL project is to improve the environment around the Mongstad refinery by increasing the capacity for the removal of hydrogen sulphide (H2S) and sulphur. This involves the installation of a sulphur recovery unit, an H2S recovery unit and a sour water stripper unit. All units are to be installed and the existing facilities upgraded with only a short shut-down period for coupling the new units to the existing plant.Reuse of design'Every project is unique, but many of the components can be reused as 3D models with minor modifications, saving us considerable time and money. 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,' concludes Jonas Fjeld Christensen.About NLI asNLI as has a long history. The group has its origin in a small mechanical workshop founded in Mjøndalen, Norway in 1946. The company has grown significantly since then, in terms of turnover, areas of competence and number of employees. The last five years, in particular, have been marked by significant expansion and diversification, not least geographically, but also into new market areas. NLI has approximately 800 highly-qualified employees.NLI as is a complete supplier of engineering and manufacturing services, technological products and new concepts and patents. Since the company is divided into five main areas, they perform equally well on small projects with only a few disciplines involved, and on large-scale EPC contracts, whether onshore, offshore or subsea.
