OCIMF SIRE 11.25 – IMO MSC / Circ.1086 “Code of Practice for Atmospheric Oil Mist Detectors”
Atmospheric Oil Mist Detection System is designed for tanks LNG Ships complying with OCIMF Requirements for supervision in the area of Hydraulic Power Packs.
SELMA implements the design, development and installation of Atmospheric Oil Mist Detections Systems in the area of Hydraulic Power Packs complying with following requirements:
- OCIMF SIRE 11.25
- IMO MSC / Circ.1086 “Code of Practice for Atmospheric Oil Mist Detectors”
SELMA Atmospheric Oil Mist Detection system reliably detects an oil mist in the atmosphere of the Engine Room / Hydraulic Room before it can reach saturation levels that pose a risk risk of fire.
In order for the ship to determine suitable positions for mounting the detectors a smoke test is required to verify air movement. In general, air will move towards ventilation extractors and turbochargers so the detector will be positioned as close as possible to that machinery.
Upon installation, at least one smoke test should be performed with all engines, ventilation and machinery fully operated to ensure that detectors are correctly installed.
The difference between mist and spray is not only the reduced size of the droplets, but also the higher energy required to create mist and its lower minimum ignition energy compared to a spray.
