Friday, December 23, 2016, Hong Kong
For approximately 13 months, an acoustic monitor will be temporarily established on the seabed in each of the following locations (WGS 84 Datum):
(A) 22 deg. 09.851’N / 113 deg. 57.148’E
(B) 22 deg. 09.187’N / 113 deg. 57.199’E
(C) 22 deg. 09.170’N / 113 deg. 56.739’EThe acoustic monitor is an instrument for collecting dolphin data. It will be fixed to a cubic precast concrete block of 1.0 metre by 1.0 metre by 1.0 metre on the seabed. The total height of the acoustic monitor and the concrete block above the seabed will be about 3.0 metres.Regular diving operations for inspecting and retrieving data from the acoustic monitors will be carried out by a work boat at the above locations once every two months. One guard boat will provide assistance. The hours of operations will be from 0800 to 1700 hours. No operation will be carried out on Sundays and public holidays.

Vessels engaged in the operations will display signals as prescribed in international and local regulations.

Neopanamax vessel requirements regarding Pilot Portable Units (PPU)
Friday, December 23, 2016, Panama Canal, Panama
The Panama Canal Authority requires that all Neopanamax vessels intending to transit the Panama Canal install, no later than February 28, 2017, a USA standard (NEMA5-15R) 120V, AC, 3-prong power receptacle close to the designated location of the RTK antenna which is part of the Pilot Portable Unit (PPU) utilized by Panama Canal pilots.Vessels that cannot comply with the installation of the required power receptacle outside the wheelhouse due to the nature of their cargo are exempt from this compliance; however, these vessels must provide an extension cord and an alternate access to route the extension cord from a power receptacle inside the wheelhouse. This will prevent the antenna power cable from being slashed and/or ruptured by the bridge wing doors.(For information about operation in the Panama Canal, contact GAC-Wilford & McKay at gac-wilfordmckay.panama@gac.com)
