The Vos Prodect Tube Entry System is devised for a smooth cable pull-in into either a J- or I-Tube. Vos Prodect Tube Entry System has been developed with a unique mechanism that requires no moving or mechanical parts.

Ease of installation

The design has been engineered for simplicity and ease during installation, 0% failure/malfunction rates during pull-in, strong and durable protection of the cable and is a cost effective solution. 

hybrid polyurethane bend restrictors

The Vos Prodect Tube Entry System utilises Hybrid Polyurethane bend restrictors which reduces the amount of Polyurethane used in our system. Compared to traditional polyurethane systems which can add resistance due to cable isolation, the compact hybrid polyurethane bend restrictors allows for heat dissipation in the system which results in more effective power transfer through the cable.

elements tube entry system

  • Tube Centralizer/Bell Mouth with/without a locking piece (This can be further customised/adapted)
  • Hybrid Polyurethane bend restrictors
  • Ductile cast iron bend restrictors
  • Connection fixings


  • Easy handling, fast and efficient assembly
  • Offers swift and easy disassembly after installation allowing for cable replacement
  • Enables cable entry into the J-tube whilst maintaining integrity of the cable throughout the design lifetime
  • Secures the minimum bending radius of the cable during the pull-in and operational life
  • Withstands drag and the accompanying effects such as VIV and fatigue
  • Prevents ragging on the scour protection
  • Minimal installation time
  • Withstand installation loads and decreases the loads on the cable
  • Enables cable pull in and pull through
  • Test installation trial runs can be performed at our onsite testing facility
