        芬兰和爱沙尼亚输电系统运营商（TSO）Gasgrid Finland 和 Elering 因怀疑连接两国的海上天然气管道发生泄漏而展开调查。

        Gasgrid Finland 和 Elering 于 10 月 8 日凌晨两点前不久发现波罗的海连接海上天然气管道压力异常下降。

        根据异常的压力下降，怀疑管道出现泄漏，并根据观察结果决定隔离该管段。阀门被关闭，从而阻止了可能的泄漏。

        运输服务供应商正在准备一项行动，以调查疑似泄漏的原因并确定可能的泄漏点。必要的初步措施已经启动，并计划很快实施实际检查措施。

        Gasgrid 表示，如果观察到的压力下降似乎是由于泄漏造成管道损坏，那么根据损坏的性质，维修工作可能至少需要数月时间。

        芬兰天然气电网公司已经对疑似泄漏的天然气释放量进行了评估，并将在结果确认后根据《环境保护法》向环保部门报告。

        据芬兰运输服务局称，芬兰天然气市场的形势保持稳定，通过因科液化天然气浮式码头，天然气供应得到了保障，该码头也有能力提供芬兰在即将到来的冬季所需的天然气。

        波罗的海管道是芬兰和爱沙尼亚之间的第一条天然气管道。该项目于 2020 年初投入商业使用，结束了芬兰与欧盟天然气市场的隔绝状态，有助于确保该地区的能源供应安全。

        工程包括三段管道的建设，包括芬兰境内 21 公里长的陆上管道、77 公里长的海上管道和爱沙尼亚境内 54 公里长的陆上管道，以及爱沙尼亚境内减压站和两国境内压缩机和计量站的安装。

        152 公里长的天然气管道是双向的，每天可输送 720 万立方米天然气。

Investigation launches over suspected leak on European offshore gas pipeline

Finnish and Estonian transmission system operators (TSOs) Gasgrid Finland and Elering have launched an investigation over suspicion that there is a leak in an offshore gas pipeline that connects the two countries.

Gasgrid Finland and Elering observed an unusual drop in pressure in the Balticconnector offshore gas pipeline on October 8, shortly before 2 a.m.

Based on the abnormal pressure drop, a leak in the pipe was suspected, and the decision to isolate the pipe section could be made based on the observation. The valves were closed and thus the supposed leak was stopped.

The TSOs are preparing an operation to investigate the cause of the suspected leak and locate the possible leak point. The necessary preliminary measures have been initiated, and the plan is to carry out actual inspection measures soon.

If it appears that the pressure drop observed is due to a leak caused damage to the pipe, repair work may take at least several months depending on the nature of the damage, Gasgrid said.

Gasgrid Finland has assessed the extent of gas released in the suspected leak and will report the results to environmental authorities in accordance with the Environmental Protection Act after the results are confirmed.

According to the Finnish TSO, the situation in the Finnish gas market has remained stable, and the supply of gas has been secured through the Inkoo LNG floating terminal which has the capacity and ability to deliver the gas Finland needs in the coming winter as well.

Balticconnector is the first gas pipeline between Finland and Estonia. The project, which entered into commercial use at the start of 2020, ends Finland’s isolation from the EU gas market and helps ensure the energy security of supply in the region. 

The works comprised the construction of three pipeline sections, including the 21-kilometer-long onshore pipeline in Finland, the 77-kilometer-long offshore pipeline, and the 54-kilometer-long onshore pipeline in Estonia as well as the installation of a pressure reduction station in Estonia and compressor and metering stations in both countries.

The 152-kilometer-long gas pipeline is bi-directional and has a transmission capacity of 7.2 million cubic meters of gas per day.
