Bayou Lafourche Dredging Project Expected to Begin in 2015

/in

A $20 million project to dredge parts of Bayou Lafourche is expected to begin in early 2015. The project aims to increase Mississippi River water flow into the bayou.

Ben Malbrough, Bayou Lafourche Freshwater District executive director, said 16 to 18 months of work could start in January. This is the second $20 million dredging of the bayou in the past four years.

Money for the project comes from the Coastal Impact Assistance Program, which sends revenue from offshore energy production back to the state for restoration projects.

The program requires the project be complete by December 2016.

Hong Kong: Causeway Bay Typhoon Shelter Dredging Underway

/in

The Marine Department of the Hong Kong Special Administrative Region (SAR) has announced that marine works involving dredging operations, removal and laying of private moorings will be carried out in Causeway Bay Typhoon Shelter.

During the next three months, the works will be carried out by one grab dredger and one hopper barge with some tugs and guard boats providing assistance. 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 each working vessel will be established. Yellow marker buoys fitted with yellow flashing lights will be laid to mark the positions of the anchors extending from the working vessels.

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

Vietnam: Soai Rap Dredging Project Phase 2 Inaugurated

/in

The second phase of Soai Rap River dredging project was inaugurated on June 21. The project will allow larger vessels to navigate through the Soai Rap channel and ease the access to Ho Chi Minh City’s Hiep Phuoc Port and the relocated ports along the Saigon River.

The 54 km route begins from the Soai Rap River and ends at Saigon Premier Container Terminal (SPCT) in Hiep Phuoc Industrial Zone.

The second phase costs VND2,797 billion, of which Belgium financed EUR76 million and the remaining VND642 billion was from the city budget.

The Soai Rap River dredging scheme encompasses Tien Giang, Long An, Ho Chi Minh City and Ba Ria-Vung Tau. It is expected to accommodate the city’s rising demand for cargo transport.

The dredging project is divided into three phases. The first phase will dredge the river to a depth of 9.5m for handling ships of 30,000 to 50,000 tonnes. The second and third phase will dredge to a respective depth of 11 and 12m for ships with capacity of 50,000-70,000 tonnes and over 70,000 tonnes.

USA: Wonder Lake Dredging To Start Soon

/in

The Wonder Lake Master Property Owners Association will commence dredging of Wonder Lake this week according to the lake manager Randy Stowe.

The restoration project is designed to deepen Wonder Lake by churning up soil at the bottom of the lake and then sucking it up. The soil and water then will be deposited in the now-complete sediment drying facility to control the flow of water located in the Meadows of West Bay.

The official start date on the long delayed and debated project is up to the contractor, which the association’s board of directors hired last year on a $2.7 million contract.

USA: Buffalo River Dredging About to Start

/in

 

The final phase of the environmental dredging of the Buffalo River begins this week. The removal of close to 1 million cubic yards of contaminated sediment is one of the largest of its kind nationally.

The dredging cost of $22.7 million is funded through a 50/50 cost-share agreement with Honeywell and the EPA under the Great Lakes Legacy Act program.

According to Riverkeeper, the restoration will conclude in 2015 with the capping of sediments in the City Ship Canal and habitat restoration along the shoreline.

New Zealand: Sandspit Marina Dredging Underway

/in

The Sandspit Marina dredging program has begun and the first of five pontoon arms will be installed in August.

Marina spokesperson Graeme Maker says construction of the pontoons for the 131-berth marina began in April, but dredging did not start until the end of last month following delays in getting the Construction Management Plan approved.

“But everything is within the timeframe and we don’t expect this to affect the completion date,” Graeme says.

The $18 million project is due to be completed by the end of next year.

Australian company Pacific Pontoons and Silverdale-based company Hoppers Construction are contracted to deliver the project with about 10 to 12 staff on site.

There are still 31 berths to be sold, but Graeme says that won’t affect the delivery of the project.

“We are delighted with that result, but we hope to have them all sold before the marina is completed.”

The first area being dredged is directly in front of the Sandspit Yacht Club, where the first and smallest arm of the marina will be located.

The sandstone dredged from the area is being used to construct a bund that will serve as a temporary storage area to drain dredgings.

Two barges are expected to arrive on site in August when they will begin shipping the spoil to a dump-site off Great Barrier Island.
