PSUBS highly recommends you adhere to ABS and ASME PVHO standards for safe design, construction, modification, maintenance, and operation of your own submersible. The information and tools found on this website are offered for illustrative purposes only, and should not be relied upon as the sole reference for designing or building a submersible.   Please consult a professional engineer for approval of your design before risking your life in a submersible.
