FEATURE FLOATING POWER BARGES

Siemens Energy

While the Norwegians look offshore with concepts that also serve shoreside industry and potentially “regions”, Sie- mens Energy’s ? agship FGPP, Sea? oat, keeps evolving and “is relevant for all locations with access to the sea or large river systems”. “SeaFloat can replace conventional power barges which often run on diesel or heavy oil,” says Siemens Energy Sea-

SeaFloat, the del Mar III, was put together in Singapore by shipyard and gas plant fabrication crews. Modular Siemens plant was hoisted onto a fabricated barge which was no match for the season Sinaporeans accustomed to mammoth semisub- mersible builds. The voyage of Estrella del Mar III showed it piggybacking onto a heavy lift vessel and passing on its barge through narrow canals.

Siemens Energy based applications on a ? oating vessel,” Zissis says, adding that

SeaFloat GPPs are “marinized” tech “optimized” and specially made “to withstand motions, accelerations, and hull de? ections”.

“The gas turbine and steam turbine packages are installed on three-point mounted frames, forming single-lift structures that facilitate and expedite the installation and erection efforts at the shipyard. It’s like putting together big LEGO bricks,” he says. SeaFloats, he adds, are “wet- or dry-towed” from the shipyard. The barge’s layout and size are dependent on wheth- er the unit is fully integrated with LNG storage, regasi? cation and power plant — the Siemens FSRP concept — or related to power output.
