Design
For the construction of the platform – in due consideration of the results of soil analyses – various options for the foundations were analyzed. In the light of the depth of water and the objective for the minimum possible deflection of the structure as a whole, jacket construction has been preferred.
Key technical data for the various areas of platform construction are set out below:
Foundation
- 4 piles
- Pile diameter: 1.5 m
- Pile thickness: 18 mm / 40 mm
- Pile length: 38 m
- Pile weight: 37 t
- Ramming; characteristic: high rigidity, low integral weight
Foundation structure
- Jacket, 26 x 26 m on the seabed
- SKN -28 m to SKN +20 m
- Vertical ladder
- Half-landing at SKN +10 m
- Panels for measuring equipment
- Vertical guide rail for UW camera
- Cathodic corrosion protectio
Platform deck
- Welded steel construction
- Dimensions: 16 x 16 m
- 2 access openings
- Deck penetration for UW camera
Wind measuring mast
- Steel lattice tower construction
- SKN +20 m to SKN +101 m
- Vertical ladder
- Rest platforms
- Brackets for equipment, bowden wire
- Lighting
- Parabolic antenna, radar
Helipad
- Welded steel construction
- SKN +25 m (5 m above the platform)
- Stairway
The FINO1 platform operates with no permanently-stationed personnel. The platform is monitored centrally from onshore. The platform can be accessed by ship or helicopter. The platform is provided with a helipad, in order to ensure the maximum possible time window for access to the platform, even in poor weather.
