Crowcon – Field of use a gas detector equipment#5: Marine

The marine environment is potentially dangerous; Everyone knows the risks at sea such as hurricanes, large waves, such as reefs and coral reefs. However, few people are interested in crew members when they have to work in cons restricted spaces, or the dangers caused by the cargo that the seagoing vessel is carrying or the work being carried out on board.

To ensure the safety of crew members, gas monitoring equipment is necessary. Gas detection equipment requires special marine environment conformity tests and certifications to ensure conformity to the harsh environment in which it must operate. Safety systems approved by the countries or registration of the vessel, determine the type and volume of the approved equipment to which the vessel must be equipped.

The Certificate of Approval (MED) is recognized on an international scale. Gas detectors supplied to sailors on board registered in a European country must accept MED and display MED approval (wheel) labels. Crowcon offers a wide range of gas detectors with type label marks, ideal for the use of ships on board, to enable compliance with the MED directive.

The International Convention on the Safety of Life at Sea (SOLAS) is one of the oldest conventions of its kind. The first version was passed in 1914 after the Sinking of the United States “TITANIC” with the loss of more than 1500 people. The current version is the 1974 SOLAS version which came into effect in 1980. Parts of the Convention apply to all ships, including small boats.

Chapter 1 provides information on the application and definition of requirements for the maritime industry, specifically on the possibility of applying this requirement by type of vessel. In short, vessels classified as passengers or cargo ships larger than 500 tons of raw and engaged in international travel must comply with this requirement. The regulations, unless explicitly stated, do not apply to:

  • Warships and troops.
  • Cargo ship under 500 tons.
  • The ship is not operated by engine
  • Wooden vessels are originally made.
  • Yachts are not involved in trade.
  • Fishing boats.

Regular amendments are made to the published version of SOLAS and adopted by referenced resolutions. There have been a number of specific resolutions for the use of portable gas detection equipment on board.

Gas detectors for enclosed spaces on board
Gas detectors for enclosed spaces on board

Requirements for restricted spaces, also known as enclosed spaces – Confined (Enclosed) Space Entry (CSE)

Process overview

  • On 1 January 2015, in SOLAS RESOLUTION MSC.350 (92), mandatory for all crew members on board with limited space missions and rescues in this space or participating in rescue training. These trainings must be held on board at least once every two months.
    • This regulation stipulates that training must include:
    • PPE Testing and Use (Personal Protective Equipment)
    • Inspection and use of communication equipment and procedures
    • Inspection and use of gas measuring devices
    • Inspection and use of rescue equipment
    • Guidance on emergency and resuscitation
  • SOLAS Resolution A.1050 (27) defines a space surrounded by:
    • “2.1 Enclosed space is a space with the following characteristics:
    • Restrict entrances and exits;
    • Inadequate ventilation; and
    • Not designed for continuous workers,
    • And includes, but is not limited to, cargo spaces, double bottoms, fuel tanks, tankers, cargo tanks, cargo compressor rooms, cargo compartments, chain lockers, free space, keels, space between barriers, boilers, , Exhaust air collection of engines, sewage tanks and adjacent connection spaces. This list is not complete and a list should be published on a per-ship basis to determine enclosed spaces. “

Gas detection

  • Entering a limited (closed) space is a dangerous activity. Not only are crew members trained in the use of handheld gas detectors, they can also participate in rescue exercises as outlined in the SOLAS solution presented above. Handheld gas detectors should be compact, easy to use with large notifications and standard lights. It must have type approval for the seagoing vessel (e.g. MED wheelmark) that shows its capabilities in the marine environment

Requirements for port support

Process overview

  • The essence of the marine industry is such that ships have to spend most of their time on the journey. This affects the way port services must operate. Fast rotation times for any requirements from the distribution of new anchors to the supply of gas detection equipment must be carried out in very specific constraints. The availability of supplies is an important consideration and establishing reliable international supply lines is an effective way to minimize delays.

Gas detection

  • Captains need international, reliable, easy and intuitive gas detection equipment to use, these are given in this industry. The detectors easily calibration of onboard gas detectors and provide crew members with reporting capabilities that show compliance can be beneficial. However, what is often ignored is the provision of specialized training materials, which relate to the application and can be used even if a vessel leaves port.
  • Crowcon has a reputation in the marine industry, with staff using Crowcon gas detectors for more than 20 years. This experience led to the development of ship-specific products, with the ability not only to withstand the harsh and diverse environments in which they had to operate, but also with the supporting accessories needed to ensure the crews had the right information and training.
