SYNOPSIS

Installation of Topsides Structure by Float-over methodology is modus of operandi whereby Topsides on sea transportation barge upon reaching the offshore site is in placed/mated with the awaiting Jacket structure. The barge is water ballasted to reduce the freeboard in order to lower Topsides onto Jacket supports while at the same moment series of mooring lines and fenders are active to guide the barge while entering the slot between the supports.  The methodology allows Topsides to be fabricated with many equipment ready for commissioning that not only reduces offshore hook-up work and standby time but also removes the need for heavy lift barge and its limitation. Therefore, it significantly reduces offshore installation cost.
