The marine sector is a global industry and is wide ranging in terms of its applications and different types of vessels including FPSO vessels, ferries and submarines.
The type of gas hazards that will be present, and subsequently the gas detection requirements, are heavily dependent on the application and the type of marine vessel being used. In this blog we’ll take a look at some of the most common gas hazards within the marine industry and in which applications they are most likely to occur.
Floating Production, Storage, Offloading Units and Tankers
Floating production, storage and offloading (FPSO) units, which are used in the production, processing and storage of oil, are home to many potential gas hazards.
Firstly, there is the risk of fire and explosion hazards, which can lead to catastrophic damage and loss of life. Combustible gas risks that may be present include methane, hydrogen, propane, LPG, solvents and gasoline fumes among others. Due to this risk, flammable gas detection is essential on FPSO vessels.
FPSO units also have confined spaces in the form of inverted tanks or voids, meaning oxygen detectors are a must for these areas to protect from the risks of oxygen depletion which can cause mental confusion, nausea, weakness and in extreme cases loss of consciousness and death.
Whilst ferries may not be home to as many gas hazards as other vessels, there are certainly still some to be aware of. On vehicle carrying ferries, for example, there may be a large build-up of emissions from vehicle exhausts which contain harmful gases such as carbon monoxide and nitrogen dioxide. Both gases are capable of causing damage to human health, causing issues such as nausea, confusion and disorientation, inflammation of the airways and increased vulnerability to respiratory infection.
Submarines may be used for a variety of purposes including salvage and exploration operations, marine science and facility inspection and maintenance. On these vessels there may be a requirement for hydrogen detection in battery storage rooms. Whilst hydrogen is a non-toxic gas, if it builds up in environments without sufficient airflow it can displace oxygen in the air leading to risk of oxygen depletion.
Gas detection can be provided in both fixed and portable forms. Our portable gas detectors protect people against a wide range of gas hazards, and include T4x, Gas-Pro, T4 and Gas-Pro TK. Our fixed gas detectors are used where reliability, dependability and lack of false alarms are instrumental to efficient and effective protection of assets and areas. Now available through Crowcon, the Sensitron SMART S-MS MED fixed detector has been designed specifically for use in marine environments. The SMART S-MS MED is fully marine certified by Lloyd’s Register in accordance with MED/3.54 Regulation whilst also being SIL-2 certified. Also available is the Multiscan++MED control panel, also MED and SIL-2 certified, able to manage and monitor up to 64 gas detectors.
