In December, the production impacted by ice during the first half of the month. The icing improved, and the second half had great production days.

 

BJV13

  • The clean up will be completed in 2023
  • The conclusion of the root cause analysis was finalized and reported to Länsstyrelsen

 

The focus in December has been the last task under the planned maintenance for 2022. The ice has impacted the production, and made some maintenance tasks more lengthy.

 

The remaining two blades repairs will be done in 2023 together with the planned maintenance.

When there is planned maintenance, roadblocks are installed.

The site team then demobilized all main activities for the last two weeks of the month to prepare for the winter break.

The standby team was though on site to attend all potential trouble shooting.

Over the Christmas break, the windfarm did produce smoothly, and no major or urgent were required.

 

Due to the winter and icing conditions, it is important for people to pay attention when going in the vicinity of the wind farm.

Additional signs were put at the entrances of the wind farm

 

It is now time to wish you MERRY CHRISTMAS and HAPPY NEW YEAR!

Important information

Late in the evening on Thursday the 21st of July, an accident occurred in the wind farm when a blade broke on turbine Björkvattnet 13 (BJV13). No people were injured in the accident. The root cause analysis has been initiated together with the supplier of the turbines to be able to determine the reason for the failure.

We have set a temporary safety distance around the affected turbine (Björkvattnet 13 – BJV13) of 250 meters. The road leading up to that specific turbine has been blocked temporarily. We apologize for any inconvenience that this might cause.

October 2021 Update

During October works continued to carry out any snag items, which are remedial works or items needing attention that were identified when the turbines are fully commissioned and inspected inside and out.

 

Re-instatement works continued at various locations around the site, and this month saw the completion of the removal of the stoned area, which had been used for storage of materials. Maintenance of the site roads continued with minor repairs being actioned as required.  De-mobilisation work continued with the site being cleared of materials and any remaining debris.

 

To summarise the status, main Installation is complete on all thirty-three (33) turbines; commissioning works have been completed on all thirty-three (33) turbines; and all thirty-three (33) turbines have completed their reliability run, the 8-day performance test and final stage before the turbine is considered operational. The Centre and South-East areas of the wind farm have achieved operational completion, which equates to two of the five sections of the wind farm.

 

November will see a continuation of re-instatement works and a continuation of remedial works once the required materials are delivered to site. The certification required for each turbine is targeted by the end of the year – which will see the wind farm’s remaining sections achieve operational completion.

September 2021 Update

September saw the last turbine go through the final commissioning inspections before progressing to the 24hour check, and then successfully completing its reliability run which is an eight-day performance test.  This month work continued to carry out any snag items, which are remedial works or items needing attention that were identified when the turbines are fully commissioned and inspected inside and out.

 

Re-instatement works continued at various locations around the site, which included the dismantling and removal of the stoned area which had been used for storage of materials, and maintenance of the site roads.  De-mobilisation work also continued with areas being cleared of materials and containers from the offices were removed from site.

 

This month saw a further one (1) turbine commissioned, and one (1) complete their reliability run.

July 2021 Update

The summer season is now underway at Björkvattnet this month.  It has brought fair weather and the holiday period in Sweden. A new single blade lifting device arrived on site at the beginning of July, and the final blades were successfully installed on the last turbine.  This concluded the main installation works for all thirty-three (33) turbines in the wind farm.

The final five (5) customer walkdowns were carried out this month, which sees the turbines inspected inside and out.  Any remedial works identified or items requiring attention are flagged up to the Contractor as ‘snags’ to be actioned in the coming weeks.

This month saw the commencement of the re-instatement works, which includes the dismantling and removal of the stoned area which had been used for storage of materials.  Works were carried out this month to prepare the turbines for a planned grid outage which started on the 27/07/21.  During the period of the grid outage, no power will be imported or exported, so 24hour tests and eight-day performance tests cannot be carried out on the turbines during this period.  The turbines were placed in a safe position prior to the outage and will remain like this for the duration, which is expected to finish 07/08/21.

 

This month saw a further one (1) turbine commissioned, and four (4) complete their reliability run.

 

To summarise the status, main Installation is complete on all thirty-three (33) turbines; commissioning works have been completed on thirty-one (31) turbines; and thirty-one (31) turbines have completed their reliability run, the 8-day performance test and final stage before the turbine is considered operational. The Centre and South-East areas of the wind farm have achieved operational completion, which equates to two of the five sections of the wind farm.

 

August will see a continuation of internal works, commissioning, and test runs as well as a continuation of the re-instatement works.

June 2021 Update

June saw the last of the heavy fall weight testing which had been carried out throughout the thaw period.  The test results were used to assess the bearing capacity of the ground to ensure heavy machinery could continue to operate safely.  The last tests on the crane hardstand area in June, showed that all frozen water was gone from the top two metres of ground.

 

As works are coming to an end and the construction phase of the project is in its latter stage, Björkvattnet welcomed representatives from The County Administrative Board (Länsstyrelsen) who visited site in June to carry out a routine inspection.  The site visit was very well received and positive, and Björkvattnet will continue to work closely with Länsstyrelsen until the project is fully completed.

 

The de-mobilisation operation continued this month with materials, machinery and storage containers being removed from site.  The site compound and offices are also being reduced to reflect the smaller team size as less people are present on site each day.  Only the blades remain to be installed for the final turbine to be fully erected and this will be carried out once a newly manufactured single-blade lifting device is delivered to site.

 

This month saw a further two (2) turbines commissioned, and two (2) complete their reliability run.

 

To summarise the status, main Installation is complete on thirty (32) turbines; commissioning works have been completed on thirty (30) turbines; and twenty seven (27) turbines have completed their reliability run, the 8-day performance test and final stage before the turbine is considered operational. The Centre and South-East areas of the wind farm have achieved operational completion, which equates to two of the five sections of the wind farm.

 

July will see a continuation of internal works, commissioning, test runs, and installation of the blades for the last turbine.
