Breakwater tests ‘good’

B. Btlshell). He told a meeting of the board that the 45m by 15m breakwater was returned to its site off the bay .on Xiay,

14 and anchored in position. A 9.8 m keeler has been moored on four of the test piles and will be used to obtain details of vessel behaviour in the reduced wave energy zone produced by the tyre breakwater. While results were promising, he said, they showed that further evaluation would be necessary. Mr Bushell said that tes,

ting and investigations were expected to be completed in November. Originally, the studies Were to have been concluded by late this month. “If the results are favourable and the board decides to proceed with the project," he said, “the original date of early 1982 for the first availability of berths would still be likely ” ‘
