Fitting Out

Also known as outfitting, this term refers to work that is carried out while the element is afloat. It may consist, for example, of completing any remaining necessary construction of the element prior to immersion, the addition of ballast, the installation or removal of temporary equipment such as navigation lights, survey beacons, and access shafts, and adjusting the trim of the floating element. Some of the work may be necessary before transportation (towing), but the remainder must be completed after towing. Additional construction applies mainly to steel tunnels where much of the internal structural concrete may not be completed until the element is close to its final destination. Some of the work may not be carried out until the element is supported by the immersion equipment.
