Mobile Toilet on Ship

There are mainly three types of mobile toilets on ships: simple toilets, shipboard sanitary units, and shipboard container-type toilet modules.

Simple Toilets

Some netizens have shared their experiences of using simple toilets on ships, saying that they don't even need to wipe when big waves hit. This reflects that simple toilets have a simple structure and may have certain deficiencies in terms of wave resistance. However, their advantage lies in their relatively convenient setup and use, making them suitable for ship usage scenarios with low requirements for sanitary facilities and for temporary or short-term use.

Shipboard Sanitary Units

These are integrated bathroom units on ships that combine functions such as face washing, bathing, and using the toilet. They are composed of a chassis, wall panels, ceilings, doors, shipboard hardware, sanitary ware, lighting, and water and electricity systems as a whole, adopting an overall modular design. This design makes installation simple and shortens the construction period, helping to reduce the shipbuilding cycle. Moreover, they are regulated by the industry standard CB/T 3723 - 2014, ensuring the stability of their quality and performance and meeting the daily sanitary needs of ships well.

Shipboard Container-Type Toilet Modules

• Product Features: Specifically designed for ships, they combine the sturdiness of containers with the functionality of toilets. They have features such as corrosion resistance, moisture resistance, and earthquake resistance, enabling them to adapt to harsh marine environments. Their core requirements include corrosion resistance, using galvanized steel plates or aluminum alloy materials with anti-corrosion treatment on the surface to resist seawater erosion; structural stability, with the container frame needing to pass ship sway tests to ensure wind and wave resistance; a sewage system equipped with vacuum collection or biodegradation technology, complying with the environmental protection standards of the International Maritime Organization (IMO); and space optimization, with a compact internal layout often including squatting positions, urinals, washbasins, and storage areas.
• Application Scenarios: Suitable for commercial ships such as cargo ships and cruise ships, providing long-term living support for crew members; offshore operation platforms, meeting the sanitary needs of temporary operation areas such as drilling platforms; and emergency disaster relief, allowing for rapid deployment to disaster-stricken ports or islands.
• Purchase Considerations: They need to have classification society certifications such as CCS and DNV; choose a modular design for easy replacement of parts; and give priority to manufacturers with experience in ship accessories.
• Installation and Maintenance: During installation, first embed anchor bolts on the deck with a spacing of ≤1.5m, then hoist the module to the designated position with a horizontal error of <3mm, and finally connect the shipboard sewage pipes and conduct a water tightness test with a pressure of ≥0.2MPa. In terms of maintenance, check the sealing strips monthly and clean the sewage tanks quarterly.
