  • the present disclosure also relates to a maritime evacuation system and a maritime structure.
  • inflatable liferafts are stored on deck and exposed to various environmental elements such as wind, sun, salt water, and moisture. It is therefore necessary to house the inflatable liferaft in a storage device for protecting the inflatable liferaft against surrounding environment.
  • the inflatable liferaft is most often inflated using COz gas, and any leakage can be detected by measuring the CO 2 content in the protected area. This may also be checked at the service check.
  • the present disclosure aims to overcome these disadvantages by providing an improved maritime storage device that can house and protect the inflatable liferaft from external elements and wherein leakage from a gas cylinder may be detected.
  • the gas employed often exhibits a substantial concentration of CO 2 .
  • the principal component of the inflation gas or gas blend being utilized is composed of nitrogen or air, thus mitigating the need for CO 2 and offering a more eco-conscious and sustainable alternative to the known inflation gasses.
  • the present disclosure also provide a solution to determine the pressure inside the gas cylinder without the need for opening the maritime storage device, and especially where the inflation gas mainly contain nitrogen or air.
  • a maritime storage device 1 according to the disclosure is seen from the outside.
  • An inflatable liferaft is housed inside the maritime storage device 1 and the inflatable liferafts are used as mandatory life-saving equipment throughout the world on almost any commercial ship and vessel of a given size. This type of life-saving equipment is also used on other maritime structures such as offshore platforms.
  • the inflatable liferaft is designed to be mounted on a vessel or ship.
  • the maritime storage device 1 housing the inflatable liferaft is released from its mounting and thrown or deployed into the water.
  • the maritime storage device 1 then opens and the inflatable liferaft inflates, providing a safe place for passengers and crew to wait for rescue.
