<p>This invention concerns a system for the casting of anchors meant for the mooring of floating oil producing and/or drilling platforms, for which an anchor laying craft is used, whose general arrangement consists of a deck with wells for anchors, a capstan for dealing with chains, cable drums of an improved kind, lockers for the stowing of chains built into the underside of the deck of the craft, which are led by a capstan from such lockers or back to them, along hawsepipes, and drums for winding cables, mounted on a bed. When a floating platform is being moored, an improved laying device is used which prevents any slipping or dropping after each platform chain has been fastened to the previously laid line whenever the latter has to be lowered to its place in the sag.
