Enayam Port

Tamil Research Institute
RAPID TECHNO-ECONOMIC FEASIBILITY REPORT FOR
DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
• Before commencing any piling operations, the contractors shall be required to submit calculations to
demonstrate that the appropriate standards will not be exceeded.
• Timing and programming outside sensitive seasons especially concerning underwater noise.
• Apply a change management process to modify operations, if necessary to address noise issues.
• Vehicles and generator sets to be serviced regularly and maintained properly to avoid any unwanted
generation of noise or vibration from them.
• Employees working in noisy environment should be made to wear ear muffs/ear plugs to avoid any
adverse impact of noise on them.
• Employees exposed to hand vibration while handling/operating of heavy machineries should compulsorily
wear anti vibration gloves made up of visco elastic material.
• Shock absorbing techniques should be used to minimise the impact of vibration from heavy machineries.
Heavy machineries and generators to be operated during day time only.
• A noise monitoring programme during construction should be implemented
• Preferably battery operated very low noise generating vehicles will be used in the port premises during
operational stage
• Optimising dredging activity and duration.
The noise generated from construction activities of road and rail corridors is temporary and cease upon
completion of construction phase.
• Contractor should adhere to good machineries and must take all precautions to control noise pollution.
• The Diesel Generator sets should be erected with good enclosures for controlling noise.
• A regular noise monitoring programme should be defined and implemented for the port.
Considering the very low traffic growth scenario noise barriers are not required in any of the locations along the
Road as well as the rail corridor. However in case after several years if this is found necessary then following are
the mitigation measures suggested:
• Requirement of noise barrier wall, minimum height of 2.5 m can be constructed on either side of the rail
corridor where ever found necessary. During the design of elevated structures, wind load need to be
considered for computing the height of noise barrier wall.
• Proper maintenance of the rail track and rail wagon, by frequent lubrication to avoid frictional noise.
• Allowing the rail to travel with an optimum speed.
• Noise barrier for the road where the settlements/cluster of houses (or Silence zones) will be present.
• No solid noise barriers are found necessary due to very low traffic expecting for the first years. During this
period of low traffic, only strip plantations (also called Green noise barrier) will be planted. In a green
noise barrier the individual leaves will act as noise attenuators. The smaller the size of the leaves, the
better the attenuation. Similarly, the more the number of these small leaves, the better the noise attenuation.
