CHALLENGE IMPROVE DELIVER

Pull Through Connector

The Pull Through Connector system provides a method of connection and disconnection for mooring lines at the turret.

  • Through centre pull in and disconnection of the mooring line
  • Self-aligning make up
  • Pin through hole system of locking connector

APPLICATIONS


Pull Through Connector is applicable to all turret based mooring systems whether wire, polyester or chain top section.

BENEFITS


  • Robust, simple load path connector which allows simple connection and disconnection of mooring lines at the turret
  • Dual axis rotation to eliminate out of plane bending
  • ROV operable  – no divers required
  • Simple load path with high fatigue resistance
  • No corrosion packs required
  • Mooring line can be disconnected using pull in line and temporary sheave to allow simple and efficient change out of the mooring line

FEATURES


  • Forged alloy steel construction
  • Self-aligning, no need for rigging, uses temporary sheave installed by ROV
  • Simple trunnion mounting in lugs
  • Eliminates need for uni joint
  • Can be designed for any mooring line load requirement

STORY


The Pull Through Connector system was developed in response to a need to be able to disconnect mooring lines without the ship needing to be disconnected from the buoy turret assembly. The increasing failure rate of mooring lines is such that projects expect to have to change out mooring lines during project life. Therefore a simple system for allowing disconnection of the line, laydown and re connection of a new line is highly cost beneficial with respect to offshore applications.  Historically either a connecting link or a ball and taper type connectors were used but these are extremely difficult to disconnect once in service.
The system was fully qualified in 2013 and the first deliveries were made in 2014.
