A below-deck tank compartment with gas detection and ventilation isolates hydrogen leaks from other ship systems and reduces explosion risk.

A compartment hydrogen detector cuts power to non-explosion-proof equipment when fuel concentration rises, reducing ignition risk on fuel cell ships.

A gas detector and discharge valve vent leaked fuel gas from a fuel cell ship cooling tank before buildup raises explosion risk.

Compartment gas detectors and shutoff valves isolate fuel leaks in a fuel cell ship to stop power generation and reduce explosion risk.

Battery compartment isolation, gas detection, shutoff valves, and ventilation help contain explosion damage in fuel cell ships.

Sealed tank and fuel cell compartments with ventilation ports and gas detection help contain hydrogen leaks and prevent unauthorized discharge.

Gas detectors in tank and fuel cell compartments trigger targeted shutoff valves to stop fuel supply and halt power generation after a leak.

Multiple fuel cells, a storage battery, and degradation control keep the ship sailing after a cell fails and shift replacement to scheduled dockings.

Placing the fuel filling port inside the duct compartment concentrates flammable gas zones, freeing electrical equipment layout while reducing ignition risk.

A solid oxide fuel cell with battery buffering replaces diesel propulsion to cut CO2, exhaust, and noise in marine power.

A pivoting bracket handle and latch keep the surfboard battery housing engaged, then lift it vertically for safer grip and removal.

Using ballast tanks to store flow-battery electrolyte cuts battery footprint and weight while enabling vessel stability control through fluid transfer.

Charged electrolyte is bunkered through fluid ports to power vessel flow batteries without shore power connections or onboard fuel use.

A suspended battery tray in the pontoon lifts cells to a deck opening while preserving deck space, stability, and bilge drainage.

Filled peripheral floats increase wave stability, while a brighter attracting float redirects birds away from solar panels to reduce fouling and damage.

A conductive equalization ring paired with a soft magnetic shielding ring blocks high-frequency EMI while preventing voltage breakdown damage.

A sliding bar and pivoting link let an oil distribution box move with propeller shaft flexing while still limiting rotation under ice loads.

Maintaining positive pressure in crew and engine spaces blocks fumigant leakage from vessel cargo areas during onboard fumigation.

Using diverter valves to route nitrogen through the onboard air compressor cuts gas pipeline leakage test time and avoids a separate compressor.

A collapsible bow and telescoping hull move the payload closer to the impact zone, enabling precise detonation with less vehicle damage.

A hull tunnel opening below the impeller axis adds intersecting thrust, improving personal watercraft lateral movement and turning control.

Multiple hatch lock portions linked by one lever keep the luggage compartment sealed against wave impact while preserving easy access.

Water sprinkling in ship passages absorbs leaked ammonia gas and supports safer evacuation by limiting crew and passenger exposure.

Wing tanks and side spaces shield hydrocarbon tanks from collision damage while reducing maintenance and tank-switching delays during offloading.

A compressible bow section shortens on impact to move the payload closer to the target, improving detonation proximity while limiting hull damage.

Modular columns, pontoons, and connectors simplify offshore transport and assembly while maintaining buoyancy and stability in harsh seas.

A nested central methanol bunker layout for ULCCs preserves cargo space while reducing bulkheads, coating area, and structural weight.

A semi-submersible cargo bed and buoyant containers enable low-detection delivery to remote shores without ports or handling equipment.

Cradle-shaped supports on transverse bulkheads let a composite monocoque hull absorb shock and vibration while lowering acoustic signature.

Lateral storage recesses below a flat deck expand rider space and carrying capacity while preserving comfort and onboard storage.

Water-level control moves fish between hulls and culture tanks, reducing transfer damage during deep-sea operations.

Modular columns, pontoons, and connectors simplify construction while ballast distributes weight for offshore stability.
