1.2 Purpose of
the Regular Marine Travel Routes (RMTR) Plan
To describe the design considerations for selection of regular
marine travel routes, method of implementation and monitoring as well as
precautionary measures to minimize any potential impacts to Chinese White Dolphin
during the course of reclamation works and other construction activities of HKLR.
This Regular Marine Travel Routes Plan is prepared to
fulfil Condition 2.9 of EP-352/2009/D which states ¡§To minimize the chance of
vessel collision and the disturbance to the Chinese white dolphins, the Permit
Holder shall deposit with the Director, at least two weeks before the
commencement of the construction of the Contract, three hard copies and one
electronic copy of a plan showing the regular marine travel routes of vessels
moving to and from the Contract work sites. Any subsequent changes
to the regular routes shall be verified by the IEC as conforming to the
requirements in the EIA Report and deposited with the Director.¡¨
This version has been updated to incorporate marine
travel routes from HKLR03 work site to the reclaimed works
area of the Three-Runway System (3RS) Projectin Appendix B.
2.1 Types of
Working Vessels
Different construction activities
in this Contract involve different types of working vessels, for example:
Laying of silt curtain and geotextile ¡V Derrick lighter,
flat top barge and tug boat.
Construction of rock platform and seawall - Derrick lighter,
flat top barge, split hopper barge, pelican barge and tug boat.
Reclamation ¡V Derrick lighter, flat top barge, split
hopper barge and tug boat.
Disposal of excavated materials - Derrick lighter, flat
top barge, split hopper barge and tug boat.
The ship particulars of different
types of working ships deployed for the construction under this Contract are attached
in Appendix C.
These working fleets can be
divided into three main categories:
2.1.1 Non self propelled working fleets in the vicinity
of the site
This category includes derrick lighters,
flat top barges, crane barges, hopper barge etc. The potential impact to Chinese White Dolphin (CWD) of
these working fleets will be low, as they will mainly station within HKLR
boundary and the maneuvering or positioning will be carried out in slow speed.
Tow, positioning and anchoring will be done by tug boats and anchor boats.
2.1.2 Self propelled working fleets in the vicinity of
HKLR site
This category includes tug boats,
anchor boats, passenger boats, sampan and pelican barges. Marine traffic
disturbance or collision risk due to this fleet category will also be low, as
the construction activities are mainly carried out nearby the HKLR site, and
most of working fleets will be slow moving (around 5 knots up to maximum 10
knots).
2.1.3 Delivery material to HKLR reclamation work site
This category comprises tug boats,
anchor boats and derrick barges. Potential impact of cumulative marine traffic
disturbance or collision risk on CWD due to the large sized and slowly moving
(around 5 to 10 knots) working fleets with relatively low traffic flow during
construction stage are anticipated to be low. Nevertheless, speed limits and
regular travel routes will be implemented to control and minimize marine traffic
disturbance on CWD.
Typically, all working vessels
will adopt the travel route shown in Appendix A every time entering or leaving
site. Specifically, material barges for public fill (i.e. split hopper barge
& derrick lighter) will adopt the route plan shown in Appendix B while
material barges for sand fill and rock fill (i.e. pelican barge) will use the
routes in Appendix B.
2.2 Design Criteria of Regular Marine Travel
Routes (RMTR)
The design criteria of this RMTR
are summarized as folllows:
2.2.1 Hotspots of Chinese White Dolphin in Brothers
Island
The existing Tung Chung Navigation
Channel falls into the Brothers Marine Park which cannot be avoided. Therefore,
the finalized marine travel route will shift along the edge of Brothers Marine
Park as much as practical. The travelling speed will be kept not exceeding 5
knots when encroaching into the Brothers Marine Park.
2.2.2 Existing Navigation Channel and Marine Traffic
Existing fairways such as Urmston
Road Channel and northern/western fairway will be selected as the main travel
routes for delivery of material to HKLR site.
The existing traffic route in the
vicinity of HKLR site and Urmston Road Channel is attached Appendix A. Because
of the existing volume of marine traffic, the contract related working fleets
are required to draw extra attention and safety awareness while passing through
this region. The marine travel routes will also be locally adjusted in order to
minimize the potential risk of marine traffic incident.
2.2.3 Practice of Navigation Safety
The licensed captain will be the
only authorized person to control the working fleets under safe marine
operation. The captain will strictly follow all navigation safety requirements
and international practices with the aids from navigation instument and the support
from marine traffic control team of Marine Department.
Markers buoys and navigation buoys
will be adopted for marine based indicators to demarcate proper navigation
channel. These aids will assist the captain to determine the proper travel
routes under actual situation and any unexpected incidents.
In addition, since fleet navigation
will also be affected by natural constraints such as wind, current, wave, etc.,
as well as other marine operators such as speed boats, turbo jets, container
vessels and river trade vessels, the marine travel routes of contract related
working fleets will be adjusted locally to avoid any incident and to ensure
safe navigation.
2.2.4 Restricted Areas and Height Restriction of Hong
Kong International Airport
According to the Airport Height
Restriction and Airport Restricted Area presented in Figure 1, there are seven
restricted areas in the vicinity of Hong Kong International Airport where
working fleets are not allowed to pass through without authorization. Moreover,
the airport height restriction limit will govern the marine travel routes of
working fleets for the delivery of reclamation materials to HKLR site.
2.2.5 Reduction of Sediment Plume at Shallow Water Areas
The Contractor will schedule,
according to the predicted tides of Hong Kong Observatory all their pelican
barges to travel into work site at high tide in order to
i.
reduce sediment plume at shallow water [of the works]
areas.
ii.
minimize mooring at Sham Shui Kok.
2.3 Selected Regular Marine Travel Routes
The main marine
travel routes entering to the HKLR site will be from the north fairway or west.
Working fleets with large storing capacity will be deployed so as to minimize
the number of trips passing through those ecologically sensitive areas.
The marine travel routes for delivering excavated rock
materials from HKLR03 work site to the
reclaimed works area of the Three-Runway System (3RS) Project. Based on the
abovementioned designed criteria, the marine travel routes for different
construction activities are designed and presented in Appendix B.
3.1 Supervision Staff
The Project Director will be the
ultimate person for minimizing ecological impacts including dolphin monitoring
and marine traffic control. The supervising staff including Project Manager,
Construction Manager, Site Foreman and the representative of subcontractors and
specialists will assist the Project Director onsite to implement all
precautionary and mitigation measures approved by the Supervising Officer.
3.2 Method of Implementation and Monitoring
The construction works are divided
into onsite and offsite works.
Onsite works include all
construcion activities such as seawall construction and reclamation within the
site area. As the working fleets are mainly stationed within the site boundary
and occasionally will be relocated, solely, to suit the work progress, the potential impacts
to CWD will be low.
Offsite works mainly comprise the
delivery of materials such as sandfill from Pearl River Estuary and public fill
from fill banks in Hong Kong.
All barges and other vessels (include tug boat, anchor
boat and other self-propelled working fleets) will be equipped with Very High
Frequency or/and GPS for track logging of vessels.
The daily record of marine travel
route of offsite working fleets will be collected and filed by the supervising
staff for inspection and monitoring purposes. Graphical plots of all the vessel
tracks overlaid on HK base map will be provided at monthly interval to SO, ETL,
IEC/ENPO to demonstrate the conformance of the vessel to the proposed route If any
vessel track log showed the approved marine travel route is not followed, formal warning will be issued to the captain
and his shipping company or material supplier.
3.3 Precautionary Measures
3.3.1 Considerations of Operation Procedure
The major ecological risk of
marine vessel is a moving vessel striking and injuring Chinese White Dolphin
during travel and navigation. Information regarding the locations of frequent
sighting near the proposed vessel routes indicated that the following would
also be required to minimize the chance of a vessel striking marine animals.
Once approaching or leaving the
entrance of the silt curtain, all vessels will travel at a speed no greater
than 5 knots for a distance of 250m from the silt curtain then at a speed no
greater than 10 knots for a distance of at least 1.5km away from the silt
curtain. The vessels can then navigate at normal speed after that distance
unless other restrictions are imposed.
If any dolphins are sighted within
250m of a vessel then the vessel will slow down to a speed no greater than 5
knots for at least 3 minutes after the last sighting.
These procedures will be applied
until current and updated dolphin sighting data is processed by the contract Environmental
Team (ET). It is expected that the works and the inclusion of the silt curtain
will not change the dolphin activity in this area so it may not necessary to
modify the above instructions and possibly the routes in the future.
However, upon required (i.e. when
the Environmental Team Leader considered review is necessary based on the CWD
monitoring data). If amendment to the regular marine travel routes has
been made, new routes will be deposited to EPD.
3.3.2 Skipper Training
The training material will be
designed and prepared by the dolphin specialist and be updated time to time
during the course of HKLR construction.
The dolphin specialist is
responsible to provide training to the trainers of HKLR¡¦s main contractor
(Train the Trainer Scheme). The training will be given by the dolphin
specialist or training personnel approved by IEC/ENPO or AFCD.
All captains and the supervising
staff should undergo training to learn about local dolphins and porpoises. They
should be trained to be aware of the protocol for ¡¥dolphin friendly¡¦ vessel
operation (refer to the Code of Conduct for Dolphin Watching Activities from
AFCD).
The training course will be given
to the licensed vessel captains by the trainers within three working days after
commencement of working onsite and refreshment course will be provided every
quarter.
All the relevant training records will
be submitted to SO, IEC/ENPO at monthly interval to demonstrate the conformance
to the EM&A documents.
The training material and its
updates will also be provided to SO and IEC/ENPO for records.
This RMTR Plan presents a review
of major construction works of HKLR, working fleets particulars and design
criteria of marine travel routes. According to the review, preferred marine
travel routes for different construction works are recommended. Method of
implementation and monitoring as well as precautionary measures are proposed to
minimize any potential impacts to Chinese White Dolphin during the course of
reclamation works and other construction activities of Contract No. HY/2011/03
for HKLR.
