Moonpool Door Cylinders

Manufacturing in compliance with all major standards


A Moonpool Door on the bottom hull of a vessel opens and closes to allow direct access to the sea. They provide shelter and protection so that work can be done in comfort and safety rather than on a deck exposed to the elements. Moonpools are a feature on many marine drilling platforms, drillships, diving support vessels, and marine research vessels.
