SPECIAL EXPERTISE
In over 30 years and with over 800 projects undertaken, we have gained special expertise in the areas of cryogenic gas transfer systems, ice technology, process safety, automation and control, shallow water technology and subsea technology. This special expertise has been strengthened and successfully utilized in numerous projects and making IMPaC a competent partner for these challenging areas.
Cryogenic Gas Transfer Systems
IMPaC provides engineering and consultancy services for gas treatment modules and gas transfer systems, a major technical challenge due to the required cryogenic temperatures (e.g. LNG: -164° C) and the handling of liquefi ed gases in offshore environments which requires additional system precautions.Based on our knowledge and experience gained in more than 150 gas related projects, IMPaC has developed a comprehensive offshore unloading system for e.g. Liquefi ed Ethylene Gas (LEG) using shuttle vessels with a total capacity of 200,000 t LEG/year representing almost 1/3 of the world’s total LEG transport capacity. To date, the system has performed more than 3000 successful operations.
Ice Technology
‘Harsh environment’ often means ice. The IMPaC team consists of highly qualifi ed specialists with many years of experience in ice technology and research. Theoretical models and programs for the prediction of ice loads and the response of offshore structures have been developed, model tests have been carried out for comparison and in-situ measurements have been taken for verifi cation. Special IMPaC design features such as ice barrier systems have been developed. Detailed experience has been gathered in over 30 projects.

Process Safety, Automation & Control
The application of the most modern systems decreases CAPEX and OPEX and can signifi cantly increase profi tability and safety. In green fi eld development and plant renovation IMPaC has introduced the most sophisticated and state of the art technologies of safety and control system including fi eld devices supplemented by powerful and scalable remote systems management. Effi ciency and adequacy of safety instrumented and control function are examined systematically during design and proven during operation. IMPaC also offers comprehensive and unconfi ned consultancy services for automation and safeguarding concepts due to our manufacturer independence.
Shallow Water Technology
There are numerous ocean areas in the world with extreme shallow water conditions (0 to 4 m water depth), e.g. in the German Bight, in the north of the Caspian Sea and in the swamps of Nigeria. Access to these ‘amphibic’ areas is a major problem during all stages of a project; for personnel, materials, transport and installation of platforms and modules, safety. rescue and maintenance. The choice of the ‘right’ plant base (artifi cial island, barge solutions, piled platforms, or other) and the corresponding export facilities are of crucial importance. These aspects have to be covered simultaneously for all construction stages and have major impact on CAPEX and OPEX as well as on the ease of operation.
Subsea Technology
The increasing demand for hydrocarbons make exploration and production activities in ultra deepwater prospects more attractive and remunerative. IMPaC is following this trend and has participated in various subsea projects. IMPaC has developed a distributed control and automation system called “IMPaC-dCAS”, which allows remote control of all relevant subsystems and tasks in a subsea production plant via broadband Ethernet connection (water depth rated 2.000 m; step-out 100 km). This system serves as a key component for subsea production plants.

pipelines & landfalls
Pipelines are used worldwide for the transportation of liquid and gaseous media and, in special applications, for other materials. Over the years IMPaC has successfully contributed to numerous offshore pipelines throughout all project phases, from the conceptual design stage via detailed design, construction and operation up to and including decommissioning. Based on the skills and experiences available within the IMPaC team, a number of innovative solutions have been developed and implemented in the construction and operation of pipelines.
Landfalls often form an integral part of offshore projects, as the subsea pipelines, cables, etc. connect to their respective onshore systems. Whilst widely spread and proven standard construction methods are available for the long distance on- and offshore installation special attention is always to be given to the design of landfalls for subsea pipelines and cables. Generally, water intakes and outfalls also fall within the category of landfalls. Typically, these landfalls cover the section of the route from some 10 to 20 meters water depth up to an onshore tie-in point. Often, environmentally sensitive areas such as, reefs and sandbars with shallow waters, dykes, dunes, etc. are to be crossed. Thus, each landfall location has its own characteristics and challenges, and requires its own tailor made unique solution. The IMPaC team has successfully carried out a number of landfall projects. Individual solutions included specialized installation methods for shallow waters, tunnels, micro-tunnels, horizontal directional drilling and also conventional open cut trenches.

3D laser scanning and as-built generation
Laser scanning is a contact free survey method to achieve exact ±5 mm (±1 mm within a single scan) as-built data for all visible items on the respective site / platform. The direct result of laser scanning is a registered (merged) point cloud, with each point in the cloud carrying its own coordinate information. The point cloud is used to generate a fi rst basic model consisting of mere shapes.
This model is the basis for discussion in the fi rst Phase of an as built generation to set priorities for further modeling. At this stage fi rst layout drawings and views of relevant plant areas can be generated already.
In a second Phase attributes such as material grades, pipe classes, weights etc. will be added to the model. From this (smart) model MTO’s, Isos, COG data can be extracted.
Already the basic model allows engineering with 3D design software, i.e. PDMS, Tekla Structures, as all dimensional data is present and thus tie-in points, battery limits and foot prints of EQP can be displayed / arranged.
However for all models the point cloud is the sole original data pool for geometrical information. All checks will be performed against this point cloud.

3D Laser Scanning of FPSO Bonga
for SNEPCO │ Nigeria │ 2009
For replacement of water fl ood piping by pipes with a larger diameter for FPSO Bonga IMPaC has carried out 3D laser scanning and engineering services. Project challenges were fabrication & erection of class 2500# high pressure 16" NPS pipes (WT up to 1.9") and maximize pre-fabrication in order to minimize fi eld welding requirements. For the survey in a non-stable setting like a swaying vessel, special non-standard surveying methods had to be developed to guarantee results offering accuracy identical to ordinary survey on-shore.
3D laser scanning technology as part of brownfi eld engineering offers several advantages. In this project all fabrication, examination and testing was completed prior to start of shutdown, and hazards associated with in-fi eld hot work operations, as well as safety risks associated with manual measurement techniques were eliminated. Cost saving of potential lost production as the shutdown period was reduced by approximately four weeks are considerably high. Pre-fabricated spools were scanned prior to shutdown to ensure no problems occurred in fi t-up due to fabrication tolerances and cost of re-work caused by inaccurate manual measurements could be eliminated.
Scope of Work
► On-site laser scanning of water fl ood piping
► Modeling of all relevant parts

Integrated Systems for Underwater Production of Hydrocarbons (ISUP)
for BMWi - Federal Ministry of Economics and Technology │ worldwide │ 2006 - 2009
Aim of the ISUP Project was the development of major components and subsystems for underwater production of hydrocarbons. The project was carried out in co-operation with AkerSolutions, Bornemann and the University of Karlsruhe – KIT.
Within the scope of the ISUP project IMPaC developed a distributed control and automation system called “IMPaC-dCAS”, which allows remote control of all relevant subsystems and tasks in a subsea production plant via broadband Ethernet connection. The current subsea electronic module design is depth rated 2.000 mw and allows a step-out distance to shore of at least 100 km. This system serves as a key component for subsea production plants and shall be responsible for the safe and reliable automation of the production, resulting in a more effective and economic operation. “IMPaC-dCAS” facilitates a maximum degree of integration, which allows a variable set-up of subsystems.
With the development of a web based SCADA system with an interactive HMI, IMPaC qualifi es itself as a supplier for asset management of underwater process plants.
Scope of Work
► Integrated project development
► Design and web based subsea control system
► Animation and visualization of process control
► Tests with virtual and real life facilities
► Project management

»Maritime Pipe Loading System - MPLS20«
for BMWi - Federal Ministry of Economics and Technology │ worldwide │ 2007 - 2011
The MPLS20 Project is funded by the BMWi and is carried out in co-operation with Nexans Deutschland, Brugg Rohrsystems and the Technical University of Berlin. The aim of the project is the development of an innovative concept for an offshore LNG transfer system, based on vacuum insulated, fl exible cryogenic pipes with inner diameter of 16-inch up to 20-inch.
Within the project IMPaC developed an innovative tandem ‘Mooring Bay’ concept for LNG transfer system operable in harsh environmental conditions up to Hs=5.5 m. This new and patented concept allows cargo transfer between fl oating LNG terminals and LNG carriers in tandem confi guration with safe and reliable – fully aerial – handling of fl exible transfer pipes and its standard couplings (QCDC and ERC) which makes the system especially suitable for use under ice conditions.
