Bureau Veritas: Ciel & Terre floating structure and mooring design certified by NR 493
At Ciel & Terre, we engineer the Hydrelio® floating solar solution and design optimized floating PV plants with great care of each market and site’s specificities. Our main motivation is to offer highly reliable products and plants because their liability is the origin of the bankability of floating solar projects. On Ciel & Terre’s initiative, Bureau Veritas has provided in 2020 technical support to define a certification scope for floating structure design and mooring design. The study concluded that within the scope defined, Ciel & Terre is in line with applicable Rules and Regulations.
A certified anchoring design
The calculation methodology and design of the mooring system of the Hydrelio® photovoltaic farm isto be in compliance with the applicable Rules and Regulations Bureau Veritas NR 493 – Classification of Mooring systems for Permanent and Mobile Offshore Units.
The methodology applied for calculation of mooring loads and associated safety factors have also been to be in compliance with the applicable Rules and Regulations.
A qualified floating structure design
The design of the floating structure is and degradations and associated criteria defined by Ciel et Terre, which have been reviewed by Bureau Veritas and found relevant with good engineering practices.
A design evaluation conformity statement has been issued to assess that Ciel & Terre fulfils the requirements of Design of the mooring system and floating structure as per Bureau Veritas procedures.
