Energinet intends to establish a supplier qualification system (‘SQS’) for the procurement of contractors for commissioning. The scope of work for commissioning to be tendered under this SQS, may include the following items:
— provide vessel and equipment for transport, testing and installation of non-permanent sub-sea pig launcher/receiver (‘PLR’) offshore,
— operation of sub-sea valve structures (e.g. PLEM and PLR) connected to sub-sea pipeline in operation by use of ROVs operated from vessels,
— flooding of offshore pipeline systems with chemically treated sea-water by use of offshore pump spreads,
— high pressure leak testing of large diameter offshore gas transport pipeline systems with refer-ence to DNVGL-ST-F101,
— dewatering of offshore pipeline systems by use of MEG with hydrocarbon gas as propelling medium,
— purging of sub-sea valve structures (e.g. PLEM and PLR) by use of nitrogen from offshore vessel,
— coordination of offshore and onshore operations with extensive management of organizational and technical interfaces,
— transport, storage and handling of equipment and material (e.g. chemicals) to be used for pre-commissioning and dewatering within an onshore gas plant in operation,
— supply, installation and operation of temporary pig launcher for dewatering operation to be in-stalled at onshore gas plant in operation.
The SQS is intended for the procurement of contractors for commissioning for projects such as the baltic pipe project, as well as for other projects on the Danish transmission system. The SQS may be used for the award of both contracts and framework-agreements. Energinet is not obligated to purchase solely from the SQS, and may in connection with single-standing purchases choose to tender these independently.
The scope of the SQS is the supply of contractors for commissioning which interested companies have to document competences, experiences and references within.
The SQS consists of one main category.
Category 1) Contractors for commissioning,
For further details on the scope of the SQS please refer to the document – Guide to SQS – on EU-Supply.
