INTRODUCTION General Appendix A is solely intended to enable the principal elements of the Work to be identified and must be read in conjunction with all the Appendices, documents and enclosures within this Contract. Appendix A does not present exhaustive details of each activity required to complete the Work Company shall have access to updated information from Contractor’s systems, plans and reports upon Company request. 1.2 Project description 1.3 The contract relates to two projects of offshore wind farms i.e. . They are developed - respectively - by project) and project). Both companies are JVs, owned by (50% of shares) and (50% of shares). MW). The offshore wind farms will be located in Polish exclusive economic zone of Baltic Sea and are subject to Polish regulatory regime. The electricity generated in the wind farms will be exported to the Polish transmission grid, operated by Polskie Sieci Elektroenergetyczne S.A. (Polish TSO). Each wind farm has obtained separate grid connection conditions and is covered by one Grid Connection Agreement with TSO, concluded by - respectively - Each has obtained or will obtain separate set of Permits required by Applicable Law for development, construction and operation of the offshore wind farm in Polish exclusive economic zone of Baltic Sea. Both have obtained the decisions of the Polish Energy Regulatory Authority on granting support (state aid) for each project, in accordance with the Act of 17 December 2020 on the promotion of electricity generation in offshore wind farms.

During the FEED studies the two topsides were treated as they were identical, whereas the design for the substructures/jackets have been treated separately. For the detailed design however, it can be expected minor differences in topside design that must be considered. These are mainly related, but not limited to cables, hang offs and routing of cables. Both substructures are a four-legged jacket type with two piles in each corner. Ten (10)- Jubes for IAC and two (2) J-tubes for EC are installed on each substructure and one cable deck. The J-tubes shall be protected against sea ice.

Topside FEED summary Report C274-RA-A-RA-01014 will give more information. The OSS is categorised as normally unmanned; however, it is equipped with an emergency shelter including minimalistic welfare facilities and overnight stay for 12 persons in the permanent operative phase. During HUC, it shall be possible to be used for 36 persons. The OSS will not be equipped with a fresh water supply system. Instead, all fresh water supplies for the kitchen etc. will be brought on board for each manning operation. The OSS will be equipped with a helicopter winch area for emergency transfer of personnel. The primary means of access will, however, be by Service Operation Vessel (SOV) and/or Crew Transfer Vessel (CTV). The OSS will be designed with walk-to-work access facilities (2 locations), which will allow an SOV equipped with a motion-compensated gangway to safely transfer technicians and minor spare parts directly from the SOV to the OSS. The High Voltage electrical transmission system on the OSS consist of 10 IACs connected to 66 kV pluggable joints on cable deck, followed by topside 66 kV flexible cables connected to 66 kV GIS switchgears. The 66 kV GIS switchgears are connected to the 220 kV GIS switchgears via two 220/66 kV step-up transformers. The connection between the 66 kV GIS switchgear and the 220/66 kV transformers shall be Duresca busbar system. The connection between the 220/66 kV transformers and the 220 kV GIS switchgear shall be delivered by export cable contractor. From the 220 kV GIS switchgears two EC export power to the ONS. The 66 kV and 220 kV GIS switchgears for A&B system shall be segregated into separated GIS rooms by a fire wall. While the 220 kV GIS switchgear are fully separate, the 66 kV GIS switchgear are connected by a normally open bus-tie circuit breaker. The 220 kV system is directly earthed through the main transformers high voltage winding, while 66 kV system is earthed though the combined 66 kV earthing and auxiliary transformers. The topside is divided into five deck levels. Each deck level supports relevant substation equipment, control rooms, storage rooms, etc. The deck levels are Cable deck – Located on jacket structure, Cellar deck, Main deck, Cooler deck, Utility deck and Roof deck. Due to Building Permit process the OSS topsides main dimensions like topsides length, height, width, elevations, main layout, total height are frozen at FEED stage. 1.4 Abbreviations The following abbreviations shall have the meanings hereby assigned to them: 3D Model = Company’s AVEVA Plant Global 3D model ALARP = As Low As Reasonably Practical AC = Alternating Current ATS = Agreement for Technical Services BAT = Best Available Techniques BPA = Building Permit Advisor CAD = Computer Aided Design CA = Contract Award granularity=word contentanalysis={punctuationbreaks=false dehyphenate=false} layoutanalysis={tabledetect=0 layoutdetect=0} Security Classification: Restricted - Status: Draft Page 9 of 75 Appendix A EPC CB = Certification Body CFD = Computerised Fluid Dynamics CMS = Condition Monitoring System CMR = substances classified as Carcinogenic, Mutagenic, or toxic for Reproduction EAT = Earthing and Auxiliary Transformer ESON = Electrical System design and Onshore EPC Contractor (Hitachi Energy) ESI = Electrical System Infrastructure EWP = Engineering Work Package E3D = AVEVA E3D Design FAT = Factory Acceptance Test FCP = Field Check Package FEED = Front End Engineering Design HAZOP = Hazard and Operability Analysis HE = Hitachi Energy HMI = Human Machine Interface HSE = Health, Safety, Security and Environment HUC = Hook Up and Commissioning HVAC = Heating, Ventilation, Air Conditioning ISO = International Standardisation Organisation ISS = Insulation, Scaffolding and Surface kV = kilovolt LCC = Life Cycle Cost LCI = Life Cycle Information MC = Mechanical Completion MEL = Master Equipment List MPS = Master Package Specification MPST = Master Package Specification Template MTO = Material Take-Off MVA = Megavolt Ampere NORSOK = The Competitive Standards of the Norwegian Offshore Sector OSS = Offshore Substation PFD = Process Flow Diagram P&ID = Piping and Instrument Diagram granularity=word contentanalysis={punctuationbreaks=false dehyphenate=false} layoutanalysis={tabledetect=0 layoutdetect=0} Security Classification: Restricted - Status: Draft Page 10 of 75 Appendix A EPC PMS = PMT PO = ProCoSys = PS = RFCC = RFOC = SAP = SAS = SRS = SCD = SEMI = SESAM = SPIR = STID = SUS = SOV = CTV = TAC = TIE = TRA = WE = WO = 1.1.1 Definitions Power Management System Procurement Milestone Plan Purchase Order Project Completion System Tool Package Specification Ready for Commissioning Certificate Ready for Operation Certificate Data System for Working Order & Document Handling Safety and Automation System node Safety Requirements Specification System Control Diagram Standard Equipment and Material Information Computer system for finite element analysis Spare Parts Interchangeability Record Technical Information and Documentation system Safety and Utility Automation Systems Service Operation Vessel Crew Transfer Vessel Technical Acceptance Certificate Technical Information Exchange Total Risk Analysis Working Environment Work Order In this Appendix A the words and expressions established as definitions in Conditions of Contract shall have the same meaning as assigned to them in such Articles.
