Previous Projects 5
Modular Buildings Forties Echo Medic’s Module Single module – Structural Weight = 14.5 tonnes Platform crane installation
Piece Small Structures
Platform Layouts can often present restrictions Weight Geometry Access
Innovative solutions are required Brownfield modifications Installation studies
Piece Small modular solutions can allow seemingly inaccessible areas to be utilised
Bolted connections designed for in-place conditions Seal plates to provide gas-tight integrity
