2    Planning on Regular Marine Travel Routes

 

2.1   Construction Works involves the Marine Travel Routes

The work scope of this Contract does not include marine construction or vessel operation related to construction works.

 

With reference to AECOM letter “Environmental Permit No. EP-353/2009/I EP Condition 2.8 – Marine Travel Route Plan” (Ref: HKBCF/(VCP)(HY/2013/03)/ M45/100(0013)/B300436) dated on 4 August 2015, it was confirmed that all materials would be delivered from land and no marine transportation required. However, referring to Engineer’s Representative instruction (AECOM), (Ref: HKBCF/(VCP)(HY/2013/03) /C15/450(0001)/B301226) dated on 16 October 2015(Appendix B), CHEC is required to dispose the excavated marine sediment generated at designated disposal sites within Hong Kong as allocated by the Marine Fill Committee. Dumping permit has been applied under the Dumping at Sea Ordinance issued by EPD for the marine disposal works.

 

With reference to submission of Variation to Environmental Permit (6th Submission – Version 2.4) (Ref: CHEC300/OUT/2016/01/04.06/003897) dated on 5 January 2016, floating concrete batching plant will be used for providing concrete supply to construction on HKBCF. Raw material for concrete production will be delivered to the floating concrete batching plant from mainland by pelican barge.

 

After reviewing of the construction programme, the oversize precast segment will be transported from mainland by dry cargo barge.  Also, temporary asphalt mixing facility will be used for providing asphalt supply to construction on HKBCF. Raw material for asphalt production will be delivered from mainland by pelican barge.

 

With reference to AECOM letter (Ref: HKBCF/(VCP)(HY/2013/03)/ C15/440()/B314281) dated on 8 May 2017 (Appendix B), CHEC was requested to deliver surplus filling material from HKBCF project to the TM-CLKL project by marine access.

 

With reference to Airport Authority Hong Kong’s Consent letter (Ref: PSU/3206/O/205) dated on 12 June 2017 (Appendix C), CHEC was approved to deliver surplus filling material from HKBCF project to the Airport Authority Hong Kong’s Three Runway Project by marine access, the disposal location at Three Runway Project is only sand blanket filling area which presented in Figure 1 and Figure 3.

 

2.2   Design Criteria of Regular Marine Travel Routes (RMTR)

The design criteria of RMTR are summarized as follows:

 

2.2.1        Hotspots of Chinese White Dolphin in Brothers Island

Latest Chinese White Dolphin monitoring results collected under the HZMB Hong Kong Projects EM&A and the latest relevant Agriculture, Fisheries and Conservation Department report published in 2016 were used as reference information to align the marine travel routes of project related work fleets. The fundamental principle is that the routes will not go through the dolphin hotspots in Brothers Island.

 

2.2.2       Existing Navigation Channel and Marine Traffic

Existing Fairway Urmston Road Channel will be selected as the main travel route for delivery of material to HKBCF site. Please refer to Figure 3 for the Fairway Layout.

               

2.2.3        Practice of Navigation Safe

The licensed captain is the authorized person to control the working fleeting under safe marine operation. He will follow all safe navigation requirement and international practice with assistance from navigation aids as well as support from marine traffic control team of Marine Department.

 

2.2.4        Restricted Areas of Hong Kong International Airport

Regarding Airport Height Restriction and Airport Restricted Area, there are eight prohibited and restricted areas in the vicinity of Hong Kong International Airport where working fleets are not allowed to pass through unless authorization is granted. Details could be referred to Figure 1.

 

2.2.5        Types of Working Vessels

Please refer to Appendix A for the Working Fleets Particulars.

Split-bottom Barge

• Tug boat

Floating Concrete Batching Plant

Pelican Barge

Dry Cargo Barge

Derrick Lighter

               

2.2.6       Other Site Constraints

Existing marine parks, anchorage areas in Sham Shui Kok and Tuen Mun and the like are also considered during designing the proper marine routes for this Project.

 

Regarding the use of surplus filling material for reclamation, there are no sufficient of barge point located at the TM-CLKL and no barge point located at Three Runway Project, the surplus filling material to TM-CLKL and Three Runway Project should be delivered by marine access.

 

2.3        Selected Regular Marine Travel Routes

Based on the abovementioned designed criteria, the marine travel routes are proposed and presented in Figure 1 and Figure 2.
