Other Platforms


 

Application

In the design of new platforms as well as in refurbishing already operating units, topside constructions play a key role as load bearing constructive frameworks for a variety of important functional platform components such as

  • Living Quarters
  • Bracings for leg structures
  • Helidecks
  • Flare booms
  • Drilling Modules and Support Modules
  • Utilities / Process systems
  • Cranes
  • Stressed boom joints

 

Challenges

Construction material used in modern platform designs has to support cost effective construction and long-term low-maintenance operation of the units. Aspects concerning the proper choice in tubing include a streamline construction process with e.g. reduced welded connections and an increased strength to cost ratio.

 

Products and Solutions

With mechanical properties exceeding all relevant standards, excellent weldability properties and a rich choice of outside diameters/wall thicknesses and grades specifically dedicated to offshore applications, Vallourec offers a comprehensive tube program for the cost effective construction of strong and durable topside modules.
