Bulkhead and hull penetrations have the potential to cause substantial safety concerns during a seal failure (in the case of a stern tube seal) or a flooding event (in the case of a bulkhead seal or bulkhead penetration). In some instances,it is advantageous for these penetrations to have a running clearance during normal operating conditions and then seal during a flooding event. This paper will present the safety and cost benefits of a new seal approach for hull and bulkhead penetrations where a hydrogel embedded foam actuator is utilized. The paper will focus on applications of bulkhead seals, emergency backup stern tube seals and pipe and wire penetrations.
