Conception-réalisation d'une plateforme offshore multi-usages flottante pour le site d'essais SEM-REV

The contract timeline includes several phases and key milestones. The contract officially starts from the "notification du marché (t0)".

Key phases and milestones are:

• Phase conception (TF) (Design Phase): This phase begins upon the notification of the contract (t0).
• Phase réalisation (TO, PBC PSE facultative) (Realization Phase): The execution of services for this phase can only start after the notification of the corresponding firming-up decision.
• Commissioning Milestone: The POMU (Plateforme d'Observation et de Mesure Sous-marines) must be commissioned with validated controls and tests at the SEM-REV test site by September 30, 2028, at the latest.
• Phase stockage temporaire bord à quai (Temporary storage quay side Phase).
• Phase site d'essais (Test site Phase).
• Période de Garantie de Parfait Achèvement [GPA] (Perfect Completion Guarantee Period): This period extends into 2029, as indicated in the provisional detailed calendar.

While a specific overall contract end date and total duration are not explicitly stated as single dates or numbers, the provisional detailed calendar (Figure 8) indicates activities spanning from 2027 to 2029, covering various operations including controls, complementary recognition operations, transport, installation of the anchoring system, connection to the sub-marine electro-optical network, commissioning, and the guarantee period.

The core scope of work for this tender primarily involves the complete realization of a Multi-purpose Oceanic Platform (POMU), from its design and construction to its installation and commissioning on the SEM-REV test site. The contractor bears full responsibility for the project with an obligation of results towards the Contracting Authority (MOA).

The Statement of Work is structured as a single-award composite framework agreement, comprising:

• Firm Tranche (TF): This focuses on the design of the POMU. Key deliverables include:
• Project management and certification.
• Preliminary and detailed design studies, encompassing overall and detailed plans, functional and synoptic diagrams, calculation notes, analysis reports, and integration studies.
• Technical justifications for certification reviews.
• Project execution plan (PEP), which covers risk analysis, general sequencing, identification of critical equipment, industrial strategy, and detailed schedules.
• Periodic progress reports and a register for comments and responses.
• QHSE management deliverables such as a Quality Assurance Plan (PAQ) and an HSE Plan (including risk analysis, emergency response, and environmental management).
• Deliverables for regulatory compliance, including administrative files and conformity justifications.
• Optional Tranche (TO): This covers the complete realization of the POMU. Core deliverables and activities include:
• Construction or conversion and armament of the POMU, with associated deliverables like site logs, photographic records, and manufacturing files.
• Temporary storage of the platform at the quayside.
• Transportation of the platform to the SEM-REV test site.
• Installation of the platform, which involves its anchoring system and connection to the SEM-REV electro-optical network.
• Commissioning (MES) of the platform.
• Execution of controls and tests at various stages.
• Complementary reconnaissance operations.
• Reconciliation of installation works.
• Part with Purchase Orders (PBC): This relates to the extension of temporary quayside storage for the POMU.
• Optional Additional Service (PSE) (facultative): This involves the supply and implementation of a connected seabed observatory.

All deliverables must align with functional requirements, constraints, and the specified level of certification, controls, and tests, submitted for MOA/AMO approval within project timelines.
