Abstract (en)
Modular apparatus for remotely activating a wiper plug launching tool or other down-hole equipment by launching a dart (32) or other projectile along tubing to the subsea equipment. A dart is loaded into a dart sleeve or basket (34) prior to launch and subsequently loaded into a modular tool piece. The pre-loaded tool pieces are configurable prior to use dependent on operational requirement and furthermore may be independently removable from the remaining equipment facilitating maintenance and serving of individual tool pieces.
