Sizes/ Heights

WMI chooses Nexgen met masts for their reliability and ease of installation in difficult to access sites. To meet market gaps, WMI also designs and manufactures its own specialist masts. All masts are designed to meet BSXXXX. Masts are available with lightening protection options and either galvanised or stainless steel guy wires. Smaller masts are anchored with simple to install drive-in anchors, whilst larger masts use either dig-in dead-man anchors or rock pinning.

HMM10: The HMM 10m Met Mast is specifically designed for background noise studies. The addition of a Second Wind anemometer, NRG windvane and our standard Campbell Scientific logger enclosure gives a reliable cost effective solution.

HMM12,18: The HMM 12m and 18m options are designed for the smaller turbine sites, wind prospecting or longterm wind speed predictions on LIDAR sites. The standard masts are supplied with either Second Wind, NRG or Vector anemometers and wind vanes. Our standard Campbell Scientific logger enclosure supports logging of temperature and humidity data if required.

WMI's shelter analysis allows state-of-the-art extrapolation of long term wind speeds to heights well above mast height, allowing development of cost sensitive projects, minimising up front risk and uncertainty.

NEX 30,40,50,60,70: The Nexgen masts are formed from easy to slot together galvanised steel tube sections, swaged at one end. WMI has worked with these masts for a number of years and is now proud to be a Nexgen approved installer. WMI believes it has the optimum installation methodology to ensure the highest reliability whilst keeping costs down.

OLL Lattice Masts: Our lattice masts become cost effective where small footprints, high ice-loading or above 80 m wind monitoring heights are critical for your project. We have over 20 years experience in installing such masts. With our offshore partner, SeaCore we can provide you a one-stop solution for your offshore monitoring requirements.

All our masts are supplied with aluminium or stainless steel booms to meet instrument to mast separations greater than 9 mast diameters, to minimise the effects of mast wind shadow.
