PROPRIETARY DESIGN
CALLED
FORGED TUBULAR JOINTS (FTJ)

asm-to-manufacture-offshore-wind-towers-and-foundations-in-port-of-aveiro.jpeg

FTJ offers improvements in weld joints in many wind turbine foundation systems including:

  • Three-legged and four-legged jackets

  • Semi-submersible

  • Articulated multi-spar

  • Tension-leg platform

FTJs CAN BE SUPPLIED IN A WIDE RANGE OF NODE CONFIGURATIONS USED IN WIND POWER STRUCTURES

​KEY ADVANTAGES

​​

  • Only pipe-to-pipe girth welds.

  • Simple circumferential weld

    joint: 90-degree butt-weld for

    all node-to-pipe joints.

  • Semi-automatic welding possible; no manual welding needed.

  • Fewer welding procedures and qualifications needed.

  • Improved geometry provides lower stresses at the joint.

  • Drastically lower weld fatigue.

  • Longer service life due to

    enhanced fatigue resistance.

  • Easier weld inspection over

    the service life.

  • Possible reduction in branch

    diameter and total weight of the structure.

INTEGRATING OUR SUPERIOR
K, Y, & X NODES
IN YOUR SUPPORT STRUCTURE DESIGN CAN ENABLE IMPORTANT IMPROVEMENTS FOR THE ENTIRE STRUCTURE.

LOWER TOTAL STRUCTURE WEIGHT 

LONGER

SERVICE LIFE OF SUPPORT STRUCTURE 

Depending on the specific project design, steel support structures make up to 35% of total CAPEX

LOWER COST OF MANUFACTURING THE ENTIRE SUPPORT STRUCTURE

HOW DO WE MAKE THAT POSSIBLE?

We developed next generation wind turbine structure NODES 

We reduced Stress Concentration Factors on average between 43-62% depending on the type of node.

What Else Do We Do?

Continue to study existing offshore steel structure problems and identify areas for potential improvements in weld joints and node designs.

Collaborate with Project Design teams and work together on finding a best solution for a specific Marine application.
