The project comprises of sixty 3MW turbines constructed 12km offshore. Each turbine foundation consists of a monopile, which is a steel cylinder 50 metres long and 4.3 metres in diameter. A large transition piece is fixed over the top of the monopile and forms the base to which the turbine towers and substation platforms are fitted. Turbines are 80m to hub height with a blade diameter of 90m a maximum of 125m above sea level. All offshore engineering, installation works, associated subsea cabling, offshore substation and onshore works are all co-ordinated through 4Projects. The selection of the 4Projects collaboration solution enables the Client and the Owner/Operator to review & disseminate information to relevant package contractors in line with the Works Management Contract. Due to the sensitive nature of some information all key project data is uploaded to the Documents module (including engineering design drawings) to enable security controls to be deployed for effective workflow management. Full automated workflow has been utilised to enhance project workcycles. Over the first 24 months of the project 22 organisations have collaborated through 185 users based in five countries – the UK, Germany, Denmark, Norway and Italy. 13,089 items were uploaded and viewed 73,054 times - giving an upload to download ratio of 1:6. Good usage of an extranet is deemed to have a ratio equal to, or in excess of, 1:4. This means all interface management is optimal with risk being mitigated and effective communication deployed. 1129 discussions were posted siginificantly reducing e-mail, but more importantly controlling the review and decision making process during project execution providing full project auditability of project dialog between the collaborating organisations. 597 documents were marked-up using the integrated web-based Brava Viewer saving print, copying and distribtion of documents. 95% of all tasks were closed within the allocated timeframe ensuring that clarification and general project activity are managed effectively enhancing overall project efficiency.

Our Client is engaged in the execution of multiple renewables projects. The scope of their involvement is Engineering , procurement & construction of geothermal power plants Geoscientific research and evaluation  Commercial consultancy on geothermal projects Activities include well drilling and appraisal and subsequent EPCC of power plants either as Lead Investor, Solution Provider or JV Partner. A Binary Plant has been built in El Salvador using conventional ORC (Organic Rankine Cycle) technology that alternately vaporizes and condenses a working fluid. The working fluid flows in a closed loop and is circulated and re-used constantly. At the Berlin Binary Plant the working fluid is isopentane. The binary plant allows for 100% re-injection of the geothermal fluid. Condensate from the existing plant is used as make up water for the cooling tower. The selection of the 4Projects solution was firstly made for the Binary Plant in El Salvador and has subsequently been extended into project site evaluation in Germany. 4Projects has enabled the Client to control, disseminate, review and record project data throughout all phases of project identification, evaluation and execution. The solution provides accurate control of evaluation, design data and communication of design and construction data and objectives to the project stakeholders. From project commencement to January 2009 the 4Projects solution has delivered 5,566 items uploaded to date and viewed 27,790 times - giving an upload to download ratio of 1: 5 i.e., for every item uploaded it has been viewed 5. times. This is a strong indicator of enhanced efficiency and savings being accrued without the need to disseminate project evaluation and execution information across the stakeholder base. 38 Organisations have collaborated through 138 users across 4 countries - Iceland, Germany, USA and El Salvador.

MPI Offshore Limited, a pioneering company in the offshore wind turbine installation industry is utilising 4Projects web based collaboration tool to manage the construction of two new TIV (Turbine Installation Vessels). The vessels, ‘Adventure’ and ‘Discovery’ represent an investment of $550m and are due for delivery and commissioning in the 1st and 3rd quarters of 2011. The new vessels design is based on the current design of MV Resolution (built 2003), which is the only purpose built offshore Wind Turbine Installation Vessel in the world. These new vessels will be slightly bigger and will have a number of enhancements, such as a much larger crane (1,000 MT lifting capacity), larger accommodation (112 persons), helideck, enhanced jacking and positioning capability (DPII) and the ability to work in the Offshore Oil and Gas sector. As the vessels are being constructed at the Cosco Nantong Shipyard in China, MPI required a solution that enabled the timely and accurate flow of information between project partners located across the globe. Use of the 4Projects collaboration solution not only facilitates this information flow and data share - it also ensures that everyone is working to the latest version of each and every document or drawing as well as being able to show ‘who did what, and when.’ In addition, the user defined language preferences in-built in the 4Projects offering allows each registered user to select the language in which they would like to work, including simplified Chinese.

Stevens Croft Biomass Plant – Capital Value of Project was £90 million with an output of 44MW. The E.ON UK Renewables Ltd project at Stevens Croft involves the use of a mixture of renewable wood based fuels which are readily available in the local area. In the order of 475,000 tonnes of sustainable wood will be consumed per year including 95,000 tonnes of short rotation coppice.  The power station is based around a bubbling fluidised bed boiler supplied by Metso Power Oy, and a SST-800 condensing steam turbine generator supplied by Siemens AG. The SST-800 is a single-casing direct drive with reverse flow design. It works at 3,000 or 3,600rpm for generator drives up to 150MW and at variable speed up to 5,000rpm for compressor drives. The turbine can be used for both condensing and back-pressure applications. It is built from predesigned modules combined into a single unit for best parameter matching.   The plant was built by a Siemens/Kvaerner consortium. The Client Engineer and Project Manager was Mott MacDonald delivering engineering management and development.  This CO2 neutral plant is the UK's largest dedicated wood burning plant.  The intermediate section of the turbine is highly customised. It can be designed for straight flow, or equipped with internally controlled extractions or bleeds. The exhaust section is standardised in different sizes. It is prepared for axial or downward connection for condensing, while there is an upward or downward connection for back pressure. Nexans made and supplied the 33kV cable that provides the grid connection. The XLPE-insulated cable has a 500mm2 cross-section with two, three-phase, medium-voltage circuits. A total of 153km of cable provides the link to the nearest available grid connection, the Scottish Power substation around 25km away at the Chapel Cross nuclear power station.   Mott MacDonald, as one of 4Projects Enterprise Clients elected to deploy our system to aid with the cross organisational collaboration, drawing management and review coupled with overall technical and commercial management during construction. Drawing review processing automated through an approval route with senior managers as voters and viewers and commenter’s separate to the voters. The site was established in Sept 2005, the project was commissioned at the end of 2007 and 4Projects solution remained in use until July 2008. A summary of the activity on the site is shown below: 1700 + drawings have been uploaded (evidently number of revisions will be greater than that); 8000+ documents (again revisions will give more upload over the project) with custom fields for document coding deployed; 3000+ photos (principally progress, query issue and change control/recording); 250 mark-ups; 1600 discussions technical, commercial etc.; Used custom fields for coding; 13 organisations collaborating with 130 users. Used user lists to combine commercial and technical teams for distribution of data.
