It was deduced in Chapter 6 that there is already a potential demand for two berths at Kwai Chung and demand for a further two berths can be expected to arise within about 10 years. This supports the recommendation of the Container Committee that the first stage should comprise two berths and that construction of these should be planned so as to bring one of them into operation as soon as possible. The other two berths should then be constructed as and when justified by demand.
Stage 1 comprises 2 phases and is as shown on Drawing 16.
The first phase has been designed so that it would involve the minimum of reclamation, could be built quickly and could be put into operation before the completion of the second phase. The recommended design consists of a piled concrete deck 73 ft. wide backed by a mass-concrete-block seawall to retain the reclamation. On the south-eastern side a mass-concrete-block seawall would protect the reclamation and would be constructed so that it could act as a lighter quay. The north-western side of the reclamation would be left unprotected and filling would proceed along its face as and when the construction of the second phase permitted.
The first phase would comprise:-
(a) An 850-ft. containership berth with a minimum of 35-ft. depth of water alongside. (b) 900 ft. of quaywall for lighter berths.
(c) A 150-ft. length of cellular quaywall extending south east from the first berth, which
would:-
(i) Allow ships of 950-ft, length to berth.
(ii) Allow further extension of the quaywall without interfering with operations at
the 1st berth.
(iii) Provide some measure of wave protection to the lighter berths.
(d) A 100-ft. wide working apron with rails to take two container cranes.
(e) A 7.1-acre marshalling area with capacity for 1,800 containers stacked 2 high.
(f) An 8-acre area for a packing shed, workshops, offices and a lorry park.
(g) An at-grade road access from Kwai Chung Road where left-turning only would be
permitted.
The second-phase quaywall would be a cellular steel-sheet-piling structure which would retain the reclamation while the crane rails would be supported on concrete piles. The reclamation in front of the existing breakwater would be protected on the north-west by a random-rubble mound but it is not considered necessary to protect the reclamation behind the existing breakwater because of the shelter afforded.
The second phase would consist of:-
(a) A second 850 ft. containership berth, with a minimum of 35 ft. of water alongside. (b) A 150-ft. extension of the cellular quaywall to the north-west to retain the rubble
mound behind it and to facilitate further extension.
(c) An additional 7.9 acres of marshalling area.
(d) An area of 11.2 acres for packing sheds and lorry parking.
(e) A flyover which would give access to Kwai Chung Road and be capable of taking
not only normal lorry traffic but also container trailers.
As previously suggested the layout for Stage 2 as shown on Drawing 17 should only be considered as tentative in view of likely changes in future container operations. As shown it comprises a 550-ft. extension of the cellular quaywall towards Tsing Chau and further reclamation behind it and behind the breakwater. This quaywall together with the Stage 1 berths and the two 150-ft. extensions would provide three berths of 850-ft. each.
