Specialty Doors

Moon Pool ClosedwebMoon Pool ClosedwebMoon pool doors close off the opening where the moon 
pool intersects the vessel shell.
 Moon pool hatches cover 
the top of the moon pool. Both allow for safe and efficient deployment and recovery of divers and manned or 
unmanned vehicles. Design considerations include extreme 
weather, temperatures, ice loading, static and dynamic water 
pressure, and vessel motion during deployment/recovery. 
Configurations include single or multiple panels with sliding 
or hinged operation. Both products can be supplied in 
watertight or non-tight designs. As with all of our designs, 
controls include local and remote operation and indication.
