4.2 Regular Marine Travel Routes
The existing fairways, including North West Siu A
Chau, North Cheung Chau, Western Fairway, Ma Wan Fairway and Kap Shui Mun
Fairway will be followed and selected as the major marine travel routes. The
Existing Fairway Plan is shown in Figure 1. All the regular routes for working
vessels would not go through the dolphin hotspot in Brothers Islands.
The working vessels, i.e. Derrick Lighter, Flat Top, Concrete Batching Plant, Jack-up and Tug
Boat, will mainly stay and work along the Works Area at the airport channel and
Western Areas. Besides, the South East Quay of the airport island will later
develop into the loading and unloading area for construction materials such as
ready mixed concrete. The marine routes and works area is illustrated in Figure
2.
During the inclement weather, the working vessels
will go to Tuen Mun Typhoon Shelter, Yau Ma Tei Typhoon Shelter or Hei Ling
Chau Typhoon Shelter. Please refer to Figure 3 for the marine route.
For disposal of inert materials, DCVJV will deliver
the materials to the neighbouring sites of Contracts HY/2010/02 HKBCF
Reclamation and HY/2011/03 HZMB Section from Scenic Hill to HKBCF for filling
purposes, as the preferred disposal grounds as stipulated in the Contract. Upon
the inert waste has been excavated, Hopper Barge will be used to deliver the
inert waste. The Marine Route is illustrated in Figure 4.
The precast and prefabricated units will be
delivered to Hong Kong from Prefabricated Yard in Xinhui, Guangdong. Please
refer to Figure 5a for the detailed marine routing. While the precast pile cap
shell will be delivered to Hong Kong from Precast Yard in Panyu, Guangdong, and
the barge will first anchor at the immigration anchorage area for immigration
check, then deliver the precast shell to the site area directly. The Marine
Route is shown in Figure 5b.
The inspection boats will be employed for general
usage and passengers travelling to and from different works area, namely WA6,
WA4 and WA7. The marine route is shown in Figure 6.
Upon the receipt of DASO permit and approval of
Construction Waste Disposal Account, the excavated marine sediment, inert
C&D waste, slurry and bentonite will be disposed of to the following
locations:-
1. East Sha
Chau Contaiminated Mud Disposal Site - Pit IVc or Va and South of the Brothers
Contaminated Mud Disposal Site - CMP 1 for dredged sediment Type 1 Open Sea
Disposal;
2. South of
the Brothers Contaminated Mud Disposal Site – CMP1 for dredged sediment Type 1
- Open Sea Disposal (Dedicated Site) & dredged sediment Type 2 - Confined
Marine Disposal;
3. Tuen Mun
Area 38 Fill Bank for inert construction waste, excluding slurry and bentonite;
and
4. Tseung
Kwan O Area 137 Fill Bank for slurry and bentonite.
Hopper barges and tug boats are involved for the
disposal. The relevant marine routes are shown in Figure 7 and Figure 8.
Starting from the year of 2014, the cross boundary
disposal of marine sediment will be carried out. Figure 9 shows the location and the
travelling routing of the designated sediment dump pit in mainland China.
4.3 Monitoring
DCVJV
will maintain records of the use of the inspection boats under control. Such
records will include, inter alia, details, times and purpose of journeys. The
person using the works boats authorizing the journey will be required to sign
his name and title against the entries. DCVJV will present current log books
for inspection by the SOR when so required.
The following monitoring measures will be adopted.
i.
Barges for
transporting public fill or sediment will be equipped with Automatic
Identification System (AIS) for track logging of vessels.
ii.
Tug boats and
hopper barges will be installed GPS System for the purposes of recording the
marine travel route during operation.
iii.
Derrick lighters,
flat top barges, floating concrete batching plants, jack-up platforms and Ro Ro
barges will be steered by the tug boats which are installed with GPS. As such, their travel routes can be followed.
iv.
Administrative
control will be taken, one route will be randomly selected and checked once a
month.
v.
Front End Mobile
Units (FEMUs) has been installed in the barges for disposing sediment in CEDD
dump pits locally or the designated pit in mainland China.
DCVJV will search to deploy much
suitable working fleets which are equipped with AIS or GPS as possible.
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. Record shall be submitted upon SOR’s request. Warning will be noticed to the captain and
his shipping company or material suppliers if vessel track log showed the
approved marine travel route is not followed.
All vessels used for the construction of the marine
works will comply with all the relevant regulations and requirements of the
Marine Department, including:-
(a) The Shipping and Port Control Regulations
(Cap.313A);
(b) The Merchant Shipping (Miscellaneous Craft)
Regulations (Cap.313F);
(c) The Merchant Shipping (Safety) (Signals of
Distress and Prevention of Collisions) Regulations (Cap.369N);
(d) The Dangerous Goods (Shipping) Regulations (Cap
295C);
(e) The Merchant Shipping (Launches and Ferry
Vessels) Regulations (Cap 313E);
(f) Merchant Shipping (Local Vessels) Ordinance
(Cap.548);
(g) Shipping and Port Control (Works) Ordinance
(Cap.313X).
4.4 Precautionary Measures
The main
issue with the Chinese White Dolphin is a moving vessel striking and injuring
an animal during the period of travel. Information regarding the locations of
frequent sighting near the proposed vessel routes indicated that the following
would also be needed to minimize the chance of a vessel striking a dolphin.
(a) When entering into a distance of 250m from silt
curtains of HY/2011/09 sites, all vessels will travel at a speed no greater
than 5 knots, and at a speed no greater than 10 knots for a distance of at
least 1.5km away. Vessels can then increase speed after that distance unless
other restrictions apply.
(b) If any dolphins are sighted within 250m of a vessel
then the vessel will slow to a speed no greater than 5 knots for at least 3
minutes after the last sighting.
(c) Barges for delivering will be selected as large
sizes as possible to reduce the number of delivering trips.
(d) Concerning the travelling route for fill materials
to the HKLR03 site passing dolphin hotspots, it is agreed that prolonged marine
travel route to be adopted – to go further east until pass over proposed marine
park in Brothers Island and turn back to HKLR03. The speed will keep below 5 knots when
crossing the edge of the proposed marine park.
The travel route is illustrated in Figure 4.
4.5 Training
Captains of all working vessels should be required
to use regular travel routes, in order to minimize the chance of vessel
collision.
Captains of construction vessels working in the
West Lantau waters and near the Brothers Islands 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. Reference will be made to
Code of Conduct for Dolphin Watching Activities available from Agriculture,
Fisheries and Conservation Department.
