Marine works at Tseung Kwan O
Tuesday, September 3, 2019, Hong Kong

For approximately 16 months, marine works involving dredging operation and seawall construction will be carried out within the area bounded by straight line joining the following co-ordinates (WGS 84 Datum) from (A) to (J) and the adjacent shoreline:
(A) 22 deg. 18.079’N / 114 deg. 15.439’E
(B) 22 deg. 18.075’N / 114 deg. 15.439’E
(C) 22 deg. 18.062’N / 114 deg. 15.454’E
(D) 22 deg. 18.025’N / 114 deg. 15.416’E
(E) 22 deg. 17.841’N / 114 deg. 15.413’E
(F) 22 deg. 17.841’N / 114 deg. 15.368’E
(G) 22 deg. 17.833’N / 114 deg. 15.369’E
(H) 22 deg. 17.827’N / 114 deg. 15.317’E
(I) 22 deg. 17.841’N / 114 deg. 15.316’E
(J) 22 deg. 17.841’N / 114 deg. 15.274’E

The works will be carried out by a flotilla of vessels including one dredger, two hopper barges, five dumb lighters, two tugboats and two work boats. The number of vessels engaged in the works will change from time to time to suit operational requirements.

A working area of approximately 50 metres around the dredger, barges and lighters will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the dredger, barges and lighters.

A silt curtain, extending from the sea surface to the seabed, will be established within the works area. The silt curtain is a large piece of netting used to contain mud and sediments. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the extent of the silt curtain.

The hours of work will be from 0700 to 2200 hours including Sundays and public holidays. Vessels employed for the works will stay in the works area outside the hours of work.

Diving operations will be carried out from time to time during the hours of work.

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

Vessels navigating in the vicinity should proceed with caution and keep clear of the works area at slow speed, bearing in mind there are divers working in the works area.

Tuesday, September 3, 2019, Singapore

The working period for dredging works off Sultan Shoal Lighthouse has been extended. The works are now being carried out until 29 February 2020.

According to the Maritime and Port Authority of Singapore Port Marine Notice No.082 of 2019, the works will carried out 24 hours daily – including Sundays & Public Holidays – within the working area bounded by the following coordinates (WGS 84 Datum):
1) 1 deg. 14.476’N / 103 deg. 38.969’E
2) 1 deg. 14.544’N / 103 deg. 39.135’E
3) 1 deg. 13.760’N / 103 deg. 39.502’E
4) 1 deg. 13.127’N / 103 deg. 39.482’E

Dredging works will be carried out by grab dredgers, supported by hopper barges and pusher tugs. The grab dredgers will be held in position by spuds systems within the working area.

The safety zone is a circular area of 250m radius centred at the dredger.

A safety boat will be deployed to warn other craft in the vicinity of the working area.

Craft involved in the works exhibit the appropriate local and international day and night signals.

When in the vicinity of the working area, mariners are reminded to:
a) Keep well clear of the working area;
b) Maintain a proper lookout;
c) Proceed at a safe speed and to navigate with caution;
d) Maintain a listening watch on VHF Channel 22 (Jurong Control);
and
e) Communicate with Jurong Control on VHF Channel 22 for assistance, if required.

Dorian expected to start moving N-NW
Tuesday, September 3, 2019, Bahamas

At 500am EDT (0900 UTC), the eye of Hurricane Dorian was located near latitude 26.9 North, longitude 78.4 West.

Dorian is stationary just north of Grand Bahama Island. A slow north-northwestward motion is expected to begin this morning. A turn to the north is forecast by Wednesday evening, followed by a turn to the north-northeast Thursday morning. On this track, the core of extremely dangerous Hurricane Dorian will continue to pound Grand Bahama Island today.

The hurricane will then move dangerously close to the Florida east coast late today through Wednesday evening, very near the Georgia and South Carolina coasts Wednesday night and Thursday, and near or over the North Carolina coast late Thursday.

Maximum sustained winds are near 120 mph (195 km/h) with higher gusts. Dorian is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Dorian is expected to remain a powerful hurricane during the next couple of days.

Hurricane-force winds extend outward up to 45 miles (75 km) from the center, and tropical-storm-force winds extend outward up to 160 miles (260 km). A wind gust to 61 mph (98 km/h) was recently reported at Juno Beach Pier, Florida.

WIND:
Devastating hurricane conditions continue on Grand Bahama Island.
Hurricane conditions are expected within the Hurricane Warning area in Florida by this evening. Hurricane conditions are possible in the Hurricane Watch area beginning Wednesday.
In South Florida, tropical storm conditions are expected within the Tropical Storm Warning area through today, and are possible in the Tropical Storm Watch area through this morning. Along the coast of northeastern Florida and Georgia, tropical storm conditions are expected within the Tropical Storm Warning area on Wednesday.

STORM SURGE:
A life-threatening storm surge will raise water levels by as much as 10 to 15 feet above normal tide levels in areas of onshore winds on Grand Bahama Island. Near the coast, the surge will be accompanied by large and destructive waves. Water levels should very slowly subside on the Abaco Islands today.
The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide:
– Lantana FL to South Santee River SC: 4-7ft
– North of Deerfield Beach FL to Lantana FL: 2-4ft
Water levels could begin to rise well in advance of the arrival of strong winds. The surge will be accompanied by large and destructive waves. Surge-related flooding depends on the how close the center of Dorian comes to the coast, and can vary greatly over short distances.

RAINFALL:
Dorian is expected to produce the following rainfall totals through Friday:
– Northwestern Bahamas: Additional 3-6 inches, isolated storm totals over 30 inches.
– Coastal Carolinas: 5-10 inches, isolated 15 inches.
– Atlantic Coast from the Florida peninsula north of West Palm Beach through Georgia: 3-6 inches, isolated 9 inches.
– Southeast Virginia: 2-4 inches, isolated 6 inches.
This rainfall may cause life-threatening flash floods.

SURF:
Large swells are affecting the northwestern Bahamas, the Florida east coast, and the coast of Georgia. These swells are expected to spread northward along much of the remainder of the southeastern United States coast during the next couple of days.
These swells are likely to cause life-threatening surf and rip current conditions.

TORNADOES:
A tornado or two is possible near the immediate east coast of Florida through tonight. This risk will shift to immediate coastal Georgia and the coastal Carolinas on Wednesday into Thursday.
