Abstract

A maritime floatation device for using remote firing devices above and below the water line by way of non-electric or electric initiation, the maritime floatation device includes:

a) a receiver housing having a combination of at least two receivers connectable via shock tube to respective explosive means, one receiver is adapted for timed initiation for separation and the second receiver adapted for remote initiation or timed initiation in order to meet the desired required operational capabilities of the maritime floatation device;b) a releasable basket housing connected to receiver housing;c) retention means for retaining two housings together;d) separation means for deactivating the retention means so as to allow for separation the receiver housing from the basket housing upon the activation of the separation means by the explosive means initiated from a timed initiated receiver;e) a shock tube spool position able within the basket housing wherein the spool accommodates and includes a length of shock tube that is connectable to the second receiver and to explosive means so as to allow flexibility in deployment of the maritime floatation device to suit the desired standard operating procedures; and/orf) floats attachable to the receiver housing so as to allow receiver housing to float to the surface once the receiver housing is separated from the basket housing;wherein the maritime floatation device allows non-electric or electric initiation of shock-tube with properties able to be deployed and operated under water at water depths without ingress of water impacting on the reliability of the maritime floatation device.
