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.
