SSE plans 4million euro contract

PixabaySSE has put forward a contract for geotechnical works in Ireland. The works will consist of geotechnical surveys to be performed both onshore and in near shore waters.

The estimated total value for the contract is EUR 4million. The aim of the work is to gather sufficient geotechnical data to support the preliminary design, and in part the detailed design, of wind turbine generator (WTG) substructures and foundations.

The surveys are set to be done at
Arklow Bank. The work comprises 25 boreholes and 50 cone penetration tests (CPT’s) located on as yet undefined locations across the Arklow Bank development area, and associated in-situ, and geotechnical laboratory testing and factual reporting.

The boreholes shall be composite boreholes, with a capability of sampling (push/piston, coring, hammer) and downhole CPT testing as required. Coring diameter shall be 100mm minimum.

The contractor should assume that they will supply all management, technical support and competent labour, supervision, vessels, equipment, tools, materials, consumables, temporary works and each and all other resources necessary for the handling, transportation, unloading and receiving, monitoring, measuring, drilling, testing, and quality assurance necessary for the delivery of the work.

Field works shall be completed by the end of September 2018, with Laboratory testing and factual reporting in early 2019. It is expected that this work will be delivered from a purpose built or suitably converted floating and/or jack up vessel(s), as deemed appropriate.

Arklow Bank is a wind farm with a proposed capacity of 494.8MW coming from a total of a currently planned 193 turbines. it will cover an area of 64km2 and the turbine dpeths will range from 1m-35m.
