In-Depth Information
•
If desired, program the data logger in advance with the appropriate site and
sensor information (slopes and offsets). Enter the correct date and time in the
data logger.
•
Insert the data logger's data storage card or other storage device.
•
To save valuable field installation time, assemble as many components in-house
as possible. For example, sensors can be prewired and mounted on their booms.
•
Some sensors are fragile, so properly package all equipment for safe transport
to the field.
•
Pack all tools that will be needed in the field.
•
Include at least one spare of each component, when practical. The number of
spares depends on the amount of wear the equipment is expected to experi-
ence, as well as the expected lead time to obtain a replacement. The cost of the
spare equipment should be weighed against the time and effort needed to find a
replacement should the need arise.
5.3 INSTALLATION TEAM
The quality of the data collected in a wind monitoring program depends on the quality
of the installation. The installation team should have experienced personnel, one of
whom is clearly assigned a supervisory role. This will promote efficiency and safety.
The team should also have an appropriate number of personnel for the type of tower
and equipment to be installed. The installation of a 50- or 60-m tilt-up tubular tower
typically requires a crew of four, including the supervisor. Labor requirements for
installing lattice towers vary, and should be determined by a qualified engineer.
The personnel responsible for the site's selection may not always be involved in the
installation. If this is the case, it is important that the installation team leader obtain
all pertinent site information, including the latitude and longitude (verifiable with a
GPS receiver), prevailing wind direction, road maps, codes or keys to any gates,
and topographic maps and site photographs that precisely show the planned tower
location.
5.4 SAFETY
Installing a tower is inherently dangerous. Towers and equipment can fall on people,
climbers can fall from towers, and if AC power is involved or there are nearby
power lines, there is a risk of electrocution. In some remote areas, even wildlife may
pose a hazard. It is essential that the team leader strictly enforce safety protocols. In
addition, having experienced staff, following manufacturers' recommendations, and
taking common-sense precautions will reduce risks. The team should
be trained in and abide by all applicable safety procedures;
