Weighing and load-out works of oil and gas modules, Indonesia
ALE has completed the weighing and load-out of a GDU module, weighing 172t, and a TEG Contractor module, weighing 40t, in Tanjung Sekupang, Batam Island.
For the weighing operation of the GDU module, ALE utilised six load cells, ranging between 50t – 100t. The module was lifted using SPTs and set down onto the load cells, where the readings were produced.
Prior to the load-out, ALE were involved in load-out studies which consisted of ballasting works and mooring arrangements. To perform the next phase of the operation, ALE used 20 axles of SPTs to transport the module approximately 300m from the fabrication area to the load-out quay. This took approximately 40 minutes.
ALE then utilised two 20t winches, equipped with polypropylene ropes by installing four. mooring lines secured onto the jetty bollards.
Whilst performing the load-out of the TEG Contractor from the site laydown area to the load-out jetty, the module was lifted by a 250t crane and loaded onto the barge.
The modules are destined for an oil and gas project situated off the north-eastern coast of Sakhalin Island in the Russian Far East, where they will be installed in sub-Arctic conditions.
