Although MPs have said this the offshore workforce is generally in favour of offshore based SAR helios as the standby boats only cover the immediate rig area and provide no viable cover should a passenger helio ditch more than 15nms from their rig. Also in sea states above 30kts and at night the SAR helio is more effective than a boat. The only advantage a boat perhaps has is to inform an OIM (rig manager) of fire damage to his rig should the unthinkable happen and a rig catch fire and everybody is confined to the "safe refuge". I would like to see the deployment of the SAR helios plus a "super" boat responsible for a cluster of rigs. (remember the ESV Iolair!!)
