CARGO VAPOUR EMISSIONS
Unfortunately purging our vessels is required due to the nature of our business, e.g. when drydocking, yard stay of the vessel and with cargo grade changes. In 2023, we achieved a remarkable milestone by cutting our emissions from purging and venting by more than half.
This reduction is caused by two primary factors.
Firstly, a decrease in purging operations, dropping from 46 in 2022 to 32 in 2023 as a result from shifts in the market and fleet composition.
Secondly, we achieved a significant reduction in LNG venting. We learned valuable lessons from previous arrangements in conditioning our LNG vessels for their new trades. Managing LNG gassing up and cooling down operations continues to be challenging, as our impact on charterers and their BOG handling capacities in this regard is substantial.
However, by emphasizing the importance of this aspect early on during discussions with charterers, we can effectively mitigate venting to the greatest extent possible. In addition to these events, our ongoing efforts in operational changes resulted in reductions in emissions levels as well.
Also though a proactive approach in engaging charterers in the petrochemical marked, we successfully secured approvals for ships with more favourable cargo tank arrival conditions, thereby minimizing the need for venting cargoes.
In 2023 we introduced a venting policy. We noticed the positive effect immediately by communication between our vessels and the Gasdesk with gas specialist at our operational department. They could discuss opportunities for reducing and/or eliminating venting, which further contributes to reducing venting and/or flaring.
Looking ahead, our focus remains on remaining vigilant and proactive in seeking new technologies to further reduce emissions related to venting. While finding such technologies has proven challenging and unsuccessful thus far, we are committed to continuously exploring new technologies and operational practices that offer potential solutions for further reducing cargo vapour emissions.
