In parallel at the HFG Vlissingen location, the 1,700-ton Breagh Alpha jacket with a length of 84 meters was built while the 1,271-ton
topsides was constructed at the Zwijndrecht location.
This Seaharvester type platform consists of a 600-ton
topsides and a 500-ton jacket, for which Heerema's engineering company, HFG Engineering, has executed the design work.
In collaboration with Daewoo Shipbuilding & Marine (DSME)--engineering, procurement, installation and construction contractor--KBR will execute the detailed engineering of
topsides for the project, which is estimated to produce reserves of 500 MMbbl of oil.
TOFCO of Trinidad, a subcontractor on the project, will be fabricating the
topsides at its yard in Trinidad.
Installation of the spar
topsides as a single integrated deck by the floatover method allows a high proportion of the hookup and pre-commissioning work to be completed onshore prior to loadout, significantly reducing the duration and cost of the offshore commissioning phase.
Sakhalin Energy has successfully completed the installation of the Lunskoye-A gas production platform
topsides, paving the way for commissioning of Russia's first LNG plant at Prigorodnoye.
