Avesta Welding in unique FLNG project

Shell Prelude FLNG will be the world’s largest offshore plant (488 m long, 74 m wide and a displacement of around 600,000 tonnes).

Böhler Welding Group Asia Pacific has received an order for 48 tonnes of welding consumables from Doosan Engineering & Construction in South Korea. The customer has ordered 316L filler metals for welding cryogenic pressure vessels destined for Shell Prelude FLNG in Browse Basin, Australia. These vessels will be made in accordance with ASME section VIII, divisions I and II. Our products satisfied the demands in respect of performance at -196°C and the stringent requirements in respect of lateral expansion and elongation. Qualification of the welding procedures is now under way. The following welding methods and filler metals will be used:

SAW – Avesta 316L/SKR + Avesta Flux 807
FCAW – Avesta FCW 316L SKR Cryo
TIG – Avesta 316L/SKR
MMA – Avesta 316L/SKR Cryo
