Abstract
Abstract A flexible flow through saddle for ship-to-ship refueling systems. The flble flow through saddle includes a tubular structure having a pair of ribs located on the top and bottom of the tubular structure, each rib having an aperture therein. Extending from each end of the tubular structure and having an end portion thereof connected to the tubular structure is a helical shaped wire. The opposite end portion of each helical shaped wire is connected to a coupling member. That portion of each helical shaped wire between the coupling member and the tubular structure is encased in an elastomeric material which provides for flexibility and prevents premature fatigue and rupture of a hose element connected by the coupling member to the tubular structure through the encased helical shaped wire.
