Cryogenic articulated arm modification
Removal, modification & replacement of Cryogenic pipe work lifting arms on LNG Jetty 8 & 10.
On the Isle of Grain, Medway - 10 lifting arms in total.
In 2010 National Grid identified a problem with the lifting arms that attached to the LNG ships
that deliver gas to site. If the ships were to become detached from the lifting arm during the
pumping cycle the lifting arm attachment would detach itself from the ship leaving the
product to be pumped into the atmosphere.
A modification was designed that would reduce the risk of the operation. G&M were
contracted to carry out the work, the scope of which is:
Isle of Grain - Medway
Jetty 8 & 10 area
Removal of the lifting arm using crane barges.
Transportation of the arm to the Main site for modification.
This operation has not been carried out anywhere else G&M’s expertise and innovation has
been used to help other sites perform this project.
