Description
50Hertz Transmission GmbH, acting as a utility contracting entity, is conducting a non-binding Preliminary Market Consultation pursuant to Section 26 SektVO. The purpose of this consultation is to explore whether, and under which operational and commercial conditions, a compact SOV-based (Service Operation Vessel) or Walk-to-Work (W2W) offshore logistics and accommodation concept could support the continuous operation and maintenance (O&M) of the offshore grid connection platforms (ONAS) in the German Baltic Sea. The consultation is intended to inform potential future procurement decisions. 50Hertz is interested in practical market solutions, indicative commercial logic and the main assumptions underlying such information. No offers, binding prices, detailed cost breakdowns or internal calculation models are requested. As an indicative size reference, a concept with approximately 30–50 persons on board (POB), DP2 capability, suitable W2W access to OSS interfaces, platform supply capability and Baltic Sea operability is being considered. This indication is for orientation only and does not constitute a preferred design, a preferred supplier or a mandatory technical specification…
