DeltaTek Global – ArticuLock®

Systems to extend your weather window.

Robust assembly capable of opening up weather windows for installing subsea equipment by eliminating bending stress from rigid subsea deployment landing strings. ArticuLock® was developed in conjunction with Scottish Enterprise and OGTC funding to design and test the concept to stringent industry NS-1 and API standards, ultimately concluding with a field proven and robust design.

Deltatek’s ArticuLock® technology provides Open-water, Riser, Casing or Landing String articulation, even in extreme storm conditions to;

  • expand the weather window for deployment of sub-sea trees, flow-bases, EDP/LRPs, casing strings etc by >400%
  • eliminate low cycle fatigue (remove stiffness) associated with hang-off or suspending loads during riserless or open-water operations
  • provide a contingency to allow Subsea deployment or intervention operations to continue even in high significant wave height, sea-swell or loop current conditions
  • reduce Waiting on Weather time
