Weighing, transportation and load-out of two jackets, Qatar
ALE has successfully completed the weighing, transportation and load-out of two jackets in Ras Laffan, Qatar.
Both jackets were weighed using eight 600t weightors. The jackets weighed 2,628t and 2,581t and measured 57.04m long x 35m wide x 36.80m high, making these jackets the largest and heaviest jacket to ever be fabricated in Qatar.
ALE transported the jackets from the fabrication yard to the quayside. ALE used 144 axle lines of Gen 3 SPMTs in a 6 x 2 file 24 configuration.
In consideration of the site restrictions and the limitations set by the semi-submersible barge, a side load-out was performed on the barge to enable the jacket to float-off once offshore.
The load-out operation was fully controlled by a self-ballasting system of the semi-submersible barge. Each load-out operation took approximately three hours to complete.
