SPARES & REPAIRS
FEATURE SPONSOR
ENSURING A RELIABLE SOURCE FOR SPARE PARTS
A comprehensive servicing and maintenance programme is important for wind turbine operators, but in order to protect revenue and reduce costs it is vital to have a reliable source of spare parts close at hand. Fluctuating lead times from OEMs make a partnership with a third party component supplier very attractive.
“We’re constantly working on ways of ensuring that our clients have access to spare components and service consumables when they need them” says Renewable Parts founder and Managing Director Ewan Anderson, “We’re happy when our clients are happy, and they’re happy when their turbines are working.”
INVESTMENT
With significant private sector investment over the last 12 months, and a business
development grant of £150,000 from Highland and Islands Enterprise, Renewable Parts Ltd has invested extensively in Vestas, Siemens, Bonus and Gamesa components and is able to offer a next day delivery service, direct to site, for parts and consumables across the UK and into Ireland.
YIELD LOSS
Recent extreme weather has thrown up reports of wind turbines catching fire,
broken yaw linkages, as well as more minor types of wear, damage and failure. Without the spares to carry out immediate repairs, long periods of down time and lost yield can become a problem. Yield loss can cost around £800 per MW per day.
A cubic metre of air weighs 1.225kg (assuming 15oc at sea level) and with wind speeds fluctuating in a second or two by up to 5 metres per second, intense stress forces can be inflicted on the component parts of wind turbines.
Does it make sense to have a million pound asset, subject to an uncontrolled input power source, with significant penalties for downtime, not supported by instantly available critical spares back-up?
2010 STUDY
In their 2010 study, Spare Part Logistics for Optimisation for Wind Turbines – Methods for Cost Effective Supply and Storage, Linqvist and Lundin clarify the problem with commendable simplicity:
