RSC Cure NL Lot 4 — March 2016
Cure DONG Energy REnescience B.V. has decided to establish a plant for a complete handling of unsorted
household waste (Municipal Solid Waste — MSW).
DONG Energy Thermal Power A/S will be responsible for the execution of the project on behalf of Cure DONG Energy REnescience B.V.
The project, RSC Cure NL will be based on DONG Energy's REnescience Technology, which is a technology for treatment of unsorted household waste. The purpose of the process is sorting and refining the waste for utilization in the production of bioliquid for biogas production, 2D material such as folios of e.g. plastics for the making of RDF and 3D materials such as bottles and cans for the purpose of re-cycling.
The plant will be established in Eindhoven, Holland, and will be designed with a capacity of 120 000 t of household waste per year, or 15 t/h.
This pre-qualification is specific to the REnescience Waste Water Treatment plant (WWT), referred to as LOT 4, which comprise following main processes:
4.1 Digestate aeration and sludge conditioning.
4.2 Digestate phase separation, reject holding tank and solid digestate storage.
4.3 Liquid digestate evaporation unit(s) and water and brine storage facilities.
The Processes 3.1 to 3.3 described above are to be connected to one functional unit, representing the system AD-plant.
Regarding 4.1) Digestate aeration and sludge conditioning.
The delivery comprise all electromechanical equipment required for receiving, aerating and conditioning the liquefied digestate (liquid/solid slurry at this stage). The purpose of this process is to aerate and successively remove heavy metals from the digestate by means of e.g. dosage of polymer and flocculation chemicals. The delivery will consist of the unit operations aeration and sludge conditioning as well as delivery of equipment for storage and dosing of polymers and flocculation chemicals. The requirement of an aeration stage is however a decision to be made by a potential bidder in order to conform with the required performance demands.
Regarding 4.2) Digestate phase separation, reject holding tank and solid digestate storage.
The delivery comprise all electromechanical equipment required in order to achieve an efficient solid/liquid separation of the digestate and appropriate storage facilities for the solids and liquid. The solids are to be stored prior to removal from the plant. As for the liquid storage, the REnescience plant is to recycle the water into the REnescience core scope (Lot 2). Hence, a digestate buffer tank is to be included in the supply.
Regarding 4.3) Liquid digestate evaporation unit(s) and water and brine storage facilities.
From the digestate buffer tank, a fraction of the liquid is returned to lot 2 and the remaining digestate is led to the evaporation units. The delivery comprise all electro mechanical equipment required in order to achieve a controlled split between the two streams, and to secure an efficient evaporation in order to produce zero salinity water to be returned to lot 2. Furthermore, clean water and brine buffer tanks shall be included in the scope of a potential supplier
Options
Following items are expected to be tendered as an option:
— Service and maintenance contract.
General:
Potential suppliers shall expect an explicit requirement from DONG Energy in relation to the system robustness and high degree of availability. Further specific requirements in relation to guarantees for the functionality, the power consumption, and warrantee period relevant for this sort of equipment will apply. Specific demands for guarantees, bonds and warrantees will be specified in the Call for Tender Material.
Justification for tendering the contract as a single contract, can be substantiated by addressing the three criteria that should be taken into account when contracts are tendered as one tender in Netherlands (LOT 4 is only a part of the RSC Cure NL project, which is being tendered in several lots):
A) The composition of the relevant market and the influence of the combination of the contacts on the access to the contract for a sufficient number of (smaller and mid-sized) companies in that market:
— DONG Energy sets out no specific requirements to the financial capabilities of the applicant, whereas DONG Energy also urge SME's to apply for Pre-Qualification. It is allowed for smaller and mid-sized companies to form consortia, which will help them comply with the requirements to provide guarantees and bonds, as will be prescribed in the commercial conditions of the contract.
B) The organisational consequences and risks of the combination of the contracts for the contracting entity and the tenderers:
— Each of the mentioned processes, represent multiple cross-process related interfaces, relations, and exchange of signals — and they are all process steps in an integrated water treatment process. Managing and controlling these — it tendered as separate lots — would be possible, however the technical risk profile for the project execution would increase significantly, and the only way to mitigate this risk, is to set out high requirements to resource allocation within the DONG Energy organization.
— In the project execution phase, due to the technical complexity and the overlap of the various processes, systems and hardware, it would be extremely challenging coordinating the erection-, and commissioning phase.
C) The extent of connectedness of the contracts.
— The processes represent an interconnected integrated waste water treatment system, comprising various complex process-, mechanical-, electrical-, control- and monitoring interfaces, whereas the respective processes cannot be seen as a separate single standing systems and/or tanks.
— If — hypothetically — the above mentioned processes were tendered as separate packages, the requirements for the process and media control at each interface would be unrealistically high. Each interface would require a fixed definition on media data, process parameters, monitoring, etc. This would cause an immediate impact on the project complexity and CAPEX, as the potential suppliers either would decline applying for the PQ, or alternatively increase the price capitalized by the risk, which potentially could compromise the project business case.
Basically, tendering LOT 4 as one integrated system, is based on the fact that the scope is considered as ‘one process system’, which is available on the market, where interfaces between sub-systems are crucial. It is important for the Contracting Entity to have clear system and process responsibility both in terms of responsibility of functionality during the contract and in terms of time during the construction phase. This can be ensured with a single contractor. Further, the innovative nature of the entire facility supports that the contract can be tendered as a single contract. The Contracting entity consider the scope of the contract as being a single contract from a process, market and risk perspective.
