据普氏能源资讯9月6日报道，挪威大型气田Troll 的天然气产量继续缩减，因为该气田的年度维护工作超负荷，打乱了原定的夏季计划。

挪威海上天然气网络运营商Gassco的最新消息显示，周五和周六的天然气产量将分别减少1.125亿立方米和1亿立方米，然后将恢复原定的4300万立方米/天的产量，直到周二格林威治时间04：00。

Gassco表示，周五和周六的故障是“由于延迟启动”造成的。此前，该气田曾在8月底的年度维护停工计划中停产，目前尚未进入计划工程的下一阶段。

挪威大陆架目前正处于夏季工程计划的高峰期，加上额外的现场维护，导致周五和周六的总产量分别为1.888亿立方米和1.92亿立方米。本周末将有1.496亿立方米的产能受到影响。

第37周，受影响的产量将在1.07-1.21亿立方米/天之间，英国伊斯顿兰格莱德分站开始接受为期两周的年度维护，这将使其在此期间的最大吞吐量能力关闭7200万立方米/天。流入子终端的资金已经开始减少，预计周五仅为700万立方米。总而言之，国家石油公司将在周五生产1.55亿立方米，出口流量反映短期系统的产量为1.69亿立方米/天。

英国NBP现货市场周五早盘反弹，普氏评估显示，成交估值为22.50便士，周末合约为22便士，周一则为22.75便士。这使得现货市场与下周的工作日(WDNW)合约价格接近持平，而在本周初，由于伊斯灵顿收高，现货市场曾一度走势不稳。

Norwegian Troll gas impacted by 'delayed startup' during works: Gassco

Natural gas production from Norway's giant Troll field continued to be curtailed on Friday, as over-running annualmaintenance works on the asset further disrupted the planned summer schedule.

An update from offshore Norwegian network operator Gassco indicated that production availability will be reduced by 112.5 million cu m/d Friday and 100 million cu m/d Saturday, and will then resume the originally scheduled 43 million cu m/d until 0400 GMT Tuesday.

Gassco said that Friday and Saturday's unavailability were "due to delayed startup." The asset had previously stopped production during a planned shutdown for annual maintenance in late-August, and is yet to properly enter the next phase of scheduled works.

The Norwegian continental shelf is currently at the height of its planned summer works, with additional field maintenance contributing to an aggregate production unavailability of 188.8 million cu m on Friday and 192 million cu m for Saturday. The weekend will see 149.6 million cu m of capability impacted.

Week 37 will see impacted production ranging between 107-121 million cu m/d, as well as the beginning of the UK's Easington Langeled receiving sub-terminal two-week annual works, which will close its maximum throughput capability of 72 million cu m/d for the duration.

Flows into the sub-terminal have already begun to fall back, with end-of-day nominations amounting to just 7 million cu m of receipts expected Friday.

Overall, the NCS is set to produce 155 million cu m Friday, with exit flows reflecting a short system at 169 million cu m/d.

The British NBP spot market rebounded in early trading Friday, with the Platts intraday assessment recording a 22.50 p/th valuation for within-day volumes, 22 p/th for the weekend contract, and 22.75 p/th for Monday's day ahead.

This brought the spot market to near parity with the Working Days Next Week (WDNW) contract, having previously been adrift at the beginning of the week on higher Easington receipts.
