After the completion of the preliminary HAZID, a follow-up internal meeting has been held to further discuss the critical issue of ammonia venting. One of the main challenges of employing ammonia onboard is the venting of ammonia due to the high toxicity of the fuel. During the meeting, the main rules and regulations were reviewed (IGC code and documents from the IMO’s Corresponding group discussion CCC8/INF.10) intended to be considered at this stage in this project regarding the vent mast exhaust position. On top of that a supplementary study of dispersion analysis will be performed (considering among others different temperatures, humidity etc.) and the hazardous and toxic zones will be defined.
The case of considering abatement technologies such as water scrubbers and bubblers will be investigated in a preliminary feasibility analysis, with consideration of the footprint of the drain tanks. In addition, in the case that the diluted ammonia resembles to “aqueous” ammonia in terms of the IBC Code, further consideration might be given.
The findings of the project will be disseminated in the appropriate channels providing insights into the development of the pertinent technical requirements.
