Method Statement of Construction
Marlow Development Proposal
Method Statement for Construction
Special care will be taken by SEPEL’s professional and river works experienced
team lead by
Jacksons Construction (an Environment Agency framework
Partner) to ensure a high level of safety to the general public and construction
team, as well as, to the marine life in and around the construction site.
Furthermore, minimal disruption to local businesses, residents and the areas’ many
visitors is insured by the efficient design of the civil engineering works necessary
to support the hydropower scheme.
During the construction process it will not be necessary to close the Lock cut,
Thames Path National Trial or any roadway, although a restriction to access will be
necessary in the part of the weir pool and upstream weir side around the turbine
civil engineering construction site.
Riverside Bank Preparation
Once access to the site has been restricted to ensure public safety on both land and
water, pilings will be installed on and around the weir overspill. After excavation a
concrete base will be poured forming a channel and support area for the turbines
and turbine houses, as well as a compensatory flow channel.
This channel will form the basis of a concrete weir by-pass, enabling turbine
installation and increasing the flow capacity of Marlow Weir. Additionally, this
area will be used for a Larinier fish pass to enhance the migration and movement
of fish though the area.
A structure of appropriate design, size and material will be constructed ahead of
the turbines to house the turbine gearboxes, generators and controls. New sluice
gates will be installed.

Method Statement of Construction
Two, 4.5 metre wide by 4.5 metre high by 10 metre long turbines weighing
approximately 40,000 kilograms each will be craned into place in pieces from a
water based crane.
Max Turbine Flow (m3/s) = 10 cumecs per turbine
Max Power (kW) = 335kW
Cabling and Commissioning
Power cables between the turbines and the customers/grid connection will be run
either under the river or over the weir to the grid connection point
Once final PLC programming, sensor installation /calibration and construction
decommissioning are complete, the turbines will undergo a 4 week commissioning
period where the PLC and turbines will be fine turned to ensure Operating
Agreement compliance and best output.
