1 Introduction

Uniper plans to build an import terminal in Wilhelmshaven, Germany's only deep-sea port, to import up to 2.6 mtpa renewable/green/blue ammonia (NH ), incl. NH storage, a rail tank car 3 3 loading station and a large-scale NH cracking plant to produce renewable hydrogen. Up to 3 20 % NH can be directly redistributed by rail to downstream customers as an option. The larger 3 part will be cracked to hydrogen and injected into the regulated future German hydrogen core network which will run directly alongside the terminal site.

The Plant will be designed for an annual capacity of 2,600,000 tonnes (3,800,000m³) of refrigerated liquid ammonia. This corresponds to the landing of e.g. around 100 ships of 38,000m³ storage volume each per year.

Uniper Hydrogen GmbH is aiming to realise the project with the Plant scheduled to go into operation in the early 2030s.

3 Purpose of this document

The purpose of this document is to provide the definition for the Scope of Work to be executed by the Terminal-FEED Contractor for the Terminal-FEED study of the Hydrogen Import Terminal Wilhelmshaven project (HITW).

4 Description of the project

In this chapter a description of the overall HITW project is given, including the project location, project scope, key design parameters and phasing aspects.

4.1 Project Location

The onshore facilities of the planned import terminal are to be built in Wilhelmshaven at Voslapper Groden on the premises of DFTG-Deutsche Flüssigerdgas Terminal GmbH, Düsseldorf (ownership structure: Uniper: 90%, VNG 10%).

The DFTG site is located on the Voslapper Groden in the urban area of the city of Wilhelmshaven, district of Sengwarden, parcel 019, plot 1/7. The area of the DFTG site is approx. 84 ha. The UTM32 coordinates of the corner points of the site are as follows:

East North 440096.828 5942964.430 439058.388 5942376.692 438694.730 5942985.103 439748.188 5943541.216

Table 1: UTM32 coordinates of the property vertices

On the eastern edge of the site there is a 50 m wide dyke protection zone, which cannot be built on. In addition, a small part of the area in the eastern area is already used by the LTW (LNG Terminal Wilhelmshaven GmbH) and OGE (Open Grid Europe) for the operation of the nearby FSRU-based LNG import terminal. Along the northern edge of the site there are several existing and planned pipelines and cable corridors, including the NRL (Nordsee-Ruhr-Link) which will be used by the Plant for the feed-in of the produced hydrogen. Furthermore, some areas of the site need to be kept free due to environmental requirements.

The project location is shown in the following Figure 1.

Figure 1 : Simplistic overview of the project location

4.2 Project Scope

The project is made up of several key measures. These include the design, the construction and the commissioning of a new marine infrastructure (Anleger für verflüssigte Gase, AVG – done by others) consisting of a number of berths for multiple users, a jetty control building, access trestles and a gate house at the landfall. One dedicated berth will be used by Employer for the terminal project. The required topsides including the jetty platform topsides as well as the pipe bridge for all piping and cabling between the jetty platform and the onshore site will have to be designed as part of the project’s Terminal-FEED.

The ammonia will be delivered via sea-going vessels to the dedicated NH offloading berth. For 3 the design of the berth a range of design vessels, from handy-size gas carrier (HGCs) up to Very Large Gas Carrier / Very Large Ammonia Carrier (VLGCs/VLACs) is considered. After successful mooring of a carrier and establishing cargo transfer connections, the offloading of the cargo will be done using unloading arms installed on the offloading platform to transfer the ammonia cargo from the vessel to the shore-side, i.e. the jetty. Vapour return from the onshore storage tanks to the carrier can also be done via a dedicated hard arm on the berth.

NH unloading lines, a vapour return line as well as utility lines and all types of cables will run on 3 a pipe bridge over the marine infrastructure between berth and landfall and up to the onshore site with its terminal facilities. The length of the pipe bridge between the berth and the onshore

Copyright © 2025 - Uniper - All rights reserved PMEF Template V02

site is ca. 3 km. In addition, a jetty control building will be installed containing the jetty control room and technical facilities like electrical, control and instrumentation installations.

On the onshore terminal site, ammonia storage tanks and associated facilities (such as in-tank pumps and boil-off gas management), ammonia crackers (splitting ammonia into hydrogen and nitrogen), an NH rail tank car loading system as well as all associated ancillary facilities and 3 Plant infrastructure (roads, buildings, etc.) will be built.

Reaching the site, the ammonia will be led into two new large-scale atmospheric operated ammonia storage tanks. The ammonia storage tanks and the associated facilities will be designed to allow continuous unloading of an ammonia carrier at design offloading rates.

From the ammonia storage, in-tank transfer pumps as well as external booster pumps will deliver the required feed streams of ammonia to up to 6 ammonia cracker units. In the crackers, the ammonia will be split into hydrogen and nitrogen. The split hydrogen will also be treated to the desired pipeline specification in a subsequent purification unit as well as compressed to the desired delivery pressure.

The produced hydrogen is then led to a downstream fiscal metering station before it reaches the Plant’s battery limit towards the hydrogen sales gas pipeline (Nordsee-Ruhr-Link, NRL) operated by the transmission system operator (TSO) which is north and adjacent to the project site. The pipeline will be part of the yet to be built German Core Grid for hydrogen but will be finished and ready for delivery of hydrogen from the Plant in due time for the Project.

An alternative product route is the loading of ammonia onto rail tank cars and delivery of ammonia to downstream customers via rail. For this route, a reduced volume of ammonia of the Plant’s import capacity can be fed from the ammonia storage tanks to an onsite rail tank car loading. The planned loading capacity of the RTC loading facilities is from half a train per day up to a maximum of one full train per day. Loading facilities must be developed and designed accordingly.

Key design parameters for above systems are given in section 4.3.

Apart from the above outlined core elements of the Plant, all required remaining Plant infrastructure must be planned. Such items are for example roads, fences, administration building, workshop, warehouse, central control room and local control rooms, utilities and offsites, firefighting and gas detection installation etc. This includes the northwestern access to the site via road and rail (ca. 1.5 km).

The project must comply in general with the German Federal Emission Law (BImSchG) to build and operate such a facility and will specifically also be subject to 4. and 12. BImSchV (Seveso III Directive). The related BImSchG permit is authorized for erection and operation of the plant and considers all emissions of the plant and includes additional permits, as a construction permit and a permission according to Ordinance on Installations for the Handling of Substances Hazardous to Water (AwSV). Further separate permits are required such as a dike regulation approval and a permit according to the Water Resources Act.

• Fully define the project scope, • Impose an acceptable level of quality, • Allow to proceed into EPC phase.

7 Split of project’s FEED Scope

The project’s entire FEED Scope is split into the two following FEED packages with related FEED contractors and interfaces between FEED scopes:

• Terminal-FEED • Cracker-FEED

The subject of this tender is only the Terminal-FEED. The Cracker-FEED Contractor will be assigned by Employer based on a separate process.

The Terminal-FEED will cover the jetty topsides including the NH unloading lines to the 3 onshore site, the NH Storage tanks & in-tank pumps including BOG management system, the 3 NH booster pumps to increase the NH pressure up to the operating pressure of the crackers, 3 3 the H fiscal metering downstream of the crackers and handover of the hydrogen to the 2 transmission system, as well as the NH rail tank car loading system (refer to Figure 2). This 3 includes all associated utility systems, piping, civil systems including access to the site via road and rail, electrical systems, instrumentation & control systems and telecommunication systems. The Design Scope of the Terminal-FEED is further detailed in Chap. 0.

The Cracker FEED will cover the NH crackers including purification of the produced H and the 3 2 hydrogen compression up to operating pressure of the transmission system (refer to Figure 2). This includes all associated utility systems, piping, civil systems, electrical systems, instrumentation & control systems and telecommunication systems. The Design Scope of the Cracker FEED is further detailed in Chap. 9 (only for information).

Figure 2: FEED scope split - main process equipment

To accommodate the FEED scope split, a dedicated Cracker Area (ca. 350m x 450m) will be assigned to the Cracker-FEED Contractor on the onshore project site (refer to Figure 3). The

Copyright © 2025 - Uniper - All rights reserved PMEF Template V02

Cracker-FEED Contractor shall plan all elements of his design scope within this area. Accordingly, the Terminal-FEED Contractor shall plan all elements of his design scope outside the Cracker Area.

The only deviation from this principle will be the planning of the site preparation, i.e. site grading and general soil improvement if required. In order to establish a consistent basis, the Terminal- FEED Contractor shall perform these planning activities for the whole project site including the Cracker Area. Please also refer to the descriptions of the respective deliverables (see Sections 10.13.4 and 10.13.5).

Figure 3: FEED scope split – cracker area

Each FEED contractor is fully responsible to develop and provide the deliverables in line with his Design Scope and Scope of Work for his own FEED package including interfaces to each other.

7.1 Interfaces between Terminal-FEED scope and Cracker

The Terminal-FEED contractor must consider that obtaining, and possibly clarification, of required interface information from either the Employer or the Cracker FEED contractor is part of the Terminal-FEED Contractor’s scope.

The expected interfaces between the Terminal Scope and the Cracker Scope are shown in Figure 4. The cracker technology is a new development and sensitive in terms of technology, know-how and intellectual property and is therefore strictly confidential. Employer can only share limited information and technology related information to the Terminal-FEED Contractor.

Copyright © 2025 - Uniper - All rights reserved PMEF Template V02

However, the information shared shall be suitable and sufficient for the Terminal-FEED Contractor to fulfil the obligations of his scope of services during the Terminal-FEED Study.

All designated ingoing/outgoing interfaces between the Terminal Scope and the Cracker Scope are labelled with TPC-X (Tie-in Point Cracker).

The tie-in points shall be located at the boundary of the Cracker Area or, if technical reasons demand, in the vicinity of the boundary as close to it as possible. The exact positions of the tie- in points will be aligned between Terminal-FEED Contractor, Cracker-FEED Contractor and Employer during the FEED.

8.11 Interfaces to the Marine Infrastructure

The HITW project will use a new marine infrastructure (“Anleger für verflüssigte Gase” – AVG) planned and built by Niedersachsen Ports (NPorts).

The layout of the AVG is shown in below Figure 7. It comprises an access bridge (Zufahrtsbrücke) reaching ca. 1.5km seaward from shore, and a connection bridge (Verbindungsbrücke) connecting the different jetty platforms. It is planned that the AVG will comprise initially six berths and associated platforms. The most northern berth will be used by the HITW project for mooring and offloading of NH carriers. The other berths are planned to be 3 used by different users for the import of LNG and export of CO . 2

The access and connection bridges consist of two levels – see below Figure 8 for a cross- sectional view of the access bridge (total width ca. 34 m). The lower level comprises three traffic lanes and all the piping for the LNG and CO berths. On the upper level (gallery), all equipment 2 for the unloading of the NH carriers as part of the HITW project will be installed. As indicated in 3 Figure 8, all topsides on the gallery, including all piping systems and cable trays with all required structural steel, from the AVG’s landfall up to the NH offloading platform, shall be 3 designed be the Terminal-FEED Contractor.

10.6.21 Gas dispersion, Radiation and Explosion and Toxic release Assessment and Report

The purpose of this Preliminary Radiation, Gas Dispersion, Explosion modelling is to identify effects of major accident hazards (e.g. vapour clouds, jet fires, pool fires, explosion, toxic gas releases etc.) on the sensitive locations within the plot.

Before any detailed calculation will be initiated the Terminal-FEED Contractor shall provide a description with defined scenarios including release process data and assumptions for Employers review and approval.

The results shall be used to check the safety distances on the plot (ISBL) and consequences outside the property to 3rd parties and public areas. The results shall be presented and discussed with the Employer. A Safety expert (§29a Sachverständiger) will also be consulted, organised by the Employer.

Before the Preliminary Gas dispersion, Radiation and Explosion and toxic release analysis will be started, the Terminal-FEED Contractor shall supply a Terms of Reference giving the design basis (wind speed, neutral weather conditions, location, release position, release height, release duration, leak size, process release conditions (pressure/temperature), release mass flow rates etc.) for the calculation incorporated in a structured table along the Ammonia Terminal, RTC loading, cracker and process facilities for hazardous and flammable substances as follows (ToR and Nodes to be agreed):

• Marine Ammonia Unloading Jetty including Transfer lines to shore including landfall including firefighting, spill collection, jetty control building • Ammonia Storage including BOG Liquefaction and Flare system • Cracker(s) and Flare system including Hydrogen compression and metering • Rail car loading

Loss of containment for process equipment and pipeline section shall be also taken in consideration.

The calculation shall be performed for hazardous substances e.g. liquid and gaseous ammonia and hydrogen and if applicable other flammable substances. The simulation shall be carried out preferably with PHAST or ProNuSs software.

KAS-55 Guideline “Minimum safety distances” describes basically the requirements to determine the scenarios to be considered and distinguishes two cases refer to page 31/32.

Scenarios that cannot reasonably be ruled out “Vernünftiger nicht auszuschließende Szenarien” can occur even when the operator's obligations under BImSchG Section 3, Paragraph 1 of the Major Accident Ordinance (Störfallverordnung) are met.

This section requires compliance with the state-of-the-art safety technology to mitigate leakages, i.e., in the event of a leak, leak-before-break behaviour is assumed for ductile materials. In this case, a leak size of 5 – 30 mm² can be reasonably considered. This form the basis for siting and safety distances to be considered inside the battery limit (ISBL).

Scenarios that can reasonably be excluded “Vernünftigerweise auszuschließende Szenarien (Dennoch-Störfälle)” are scenarios that can reasonably be excluded for the precautionary

Copyright © 2025 - Uniper - All rights reserved PMEF Template V02

actions for protected objects or urban development planning and defines the minimum distance to protective objects “Achtungsabstand”, the leak size is DN25 (490 mm²) for calculation in compliance with KAS-18. Only the average dispersion situation is considered. The release time from the leak is set at 10 minutes (600 seconds) in KAS-18, and the dispersion time for toxic calculation (e.g., in the case of pool evaporation) can be up to 1800 seconds.

The impacts of scenarios “Vernünftiger nicht auszuschließende Szenarien” must be limited and is not allowed to exceed the operating property. To assess impacts outside the operating property, the AEGL-2 values for 60 minutes must be used for ammonia. An exception may be made for neighboring companies with which a joint emergency plan exists; in these cases, AEGL-2 or AEGL-3 values for 10 minutes are permissible.

For the impacts of the KAS-18 scenarios, the AEGL-2 (160 ppm) values for 60 minutes must not reach protected objects (hospitals, schools, fun parks, high traffic public roads, etc.) for toxic fluids e.g. ammonia.

In addition, KAS-63 Guideline “Determination of the appropriate safety distance for gaseous hydrogen plants” can be used as reference.

Further the report shall include but not limited to:

• German codes and standards • Design basis • Table with scenarios • Thresholds for toxic gas dispersion (AEGL-2) 50%-LEL and 100%-LEL, heat radiation (kW/m2), over pressure (mbar) • Identify the major accident hazards which have the major influence on the layout configuration • Identify facilities and critical locations that may be at risk from the hazards identified (termed hazard receptors) • Quantify the consequence of the various hazards at those facilities and locations • Identify mitigation measures to reduce consequences • Recommendation of additional studies or engineering.

The results including dispersion, radiation an overpressure contours shall be incorporated into the general arrangement drawing or plot plans.

10.6.22 Fire Alarm System and Gas detection Philosophy

Fire protection systems shall be released automatically or by executive action. The fire alarm system shall be planned and installed in accordance with DIN 14675, DIN VDE 0822 Part 1+2, and the DIN EN 54 series, based on the fire alarm system concept to be developed by the Terminal-FEED Contractor. The technical requirements from the Oldenburg Fire Department must be considered during the design. Internal alarm notification in the event of a fire will be handled by the fire alarm system. The fire alarm system concept is based on the

Copyright © 2025 - Uniper - All rights reserved PMEF Template V02

fire protection concept prepared by a 3rd party on behalf of the Employer, the explosion protection concept, and the requirements of DIN 14675 Part 1. The fire alarm system must be agreed and inspected and approved by a certified expert. The F&G detection status information shall always be available in the CCR and continuously available in the Fire Station on a repeater panel. In case of power failure, a back-up power supply shall be provided. The system shall raise alarms in the CCR and Fire Station for operator awareness or action, considering detection of fires, detection of gas release, detection of releases at ammonia export pipeline, failure to execute action upon demand, function (detector, logic solver, final element) defect or failure, signal failure.

The fire alarm will also immediately inform the Plant fire brigade and the public fire brigade.

Copyright © 2025 - Uniper - All rights reserved PMEF Template V02

• Jetty • Transfer lines • Ammonia Terminal further structured in the individual required process areas • RTC loading area

Following fluids shall be reviewed and included as minimum but not limited to:

• Liquid Ammonia release and loss of content • Gaseous Ammonia release • Glycol/Water as cooling fluid • Contaminated Fire Water in case of fires or clean Fire Water as cooling protection structured as seawater fire water and potable used fire water • Ammonia Water generated from gaseous release (absorption in water) e.g. from water curtain or fire monitors • Oil e.g. from transformers etc.

For the design of any spill collection area, curbed area, rainwater event shall be taken into account in accordance with AwSV requirements and calculated based on DWA-A 117, if no enclosure has been considered.

Liquid ammonia releases shall be collected in e.g. curbed areas and pumped into spill collection vessel. The spill collection vessel shall be connected to Flare. Alternatively, the contaminated liquid ammonia shall be loaded to truck for 3rd party disposal.

Contaminated fire water may be routed and collected into the storm water basin, no release to any public drainage system shall be allowed in this event (quality check of water will be performed and either loaded on trucks for disposal or treatment).

Accidental spills may enter the drainage systems. Drainage systems shall be designed to safely convey any spilt material that is uncontained to suitable segregation, holding, treatment, and disposal facilities.

For smaller leakages it is expected that the liquid release will vaporise or can be separated quickly before reaching the drainage system.

Major releases are defined as spills which require additional local (or regional) resources and manpower. Major releases are likely to be the result of integrity failure of safety and protection systems and/or failure of major equipment and/or associated pipework.

In the event of a large release of flammable or toxic material, the plant General Alarm shall be activated and the site evacuated. The progress and development of the spill shall be monitored and evaluated via on-site CCTV from the control room while a spill response or incident management team are mobilised. All relevant ESD systems shall be activated including blowdown, where deemed appropriate.

Spill kits shall be logged, inventoried and maintained to ensure adequate spill response material is available if needed.

Site personnel shall be trained in their application and use.
