The work is split in 5 (five) following work packages:
— work package 1: offshore survey and guard vessels,
— work package 2: landfall detail engineering and construction,
— work package 3: seabed intervention,
— work package 4: pipeline installation,
— work package 5: pre-commissioning operations (PCO).
All works must be carried out according to relevant legislation, standards, authority requirements, The Contracting Authorities specifications, etc.
The SQS is intended for the procurement of contractors for offshore pipeline construction 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 onshore pipeline construction projects which interested companies have to document competences, experiences and references within.
The SQS consists of one main category.
Category 1) Contractors for offshore pipeline construction projects.
