Thailand: Dredging to Resolve Sewage Problems in Khao Ta Reservoir

/in

The Irrigation Department and Prachuap Khirikhan Province have united to resolve sewage problems in Khao Ta Reservoir, following a Royal Initiative Project, by dredging the ground and increasing the amount of oxygen dissolved in the water for improved quality in the future.

The Irrigation Department has begun the Khao Ta Reservoir development and improvement project in order to increase water quality and improve the condition of the reservoir.

Moreover, the department has combined efforts with the Hua Hin Municipality to introduce measures controlling sewage released from the community into the reservoir by setting up specific retention areas to hold the sewage and treat the waste water before its release into the sea.

Thailand: Chiang Mai Prepares for Capital Dredging Project

/in

Authorities in Chiang Mai Province have inspected the banks of the Ping River to talk with trespassers and have them move out before the start of river dredging to alleviate flooding problems along the river.

The board will take about three months to observe the flow and characteristics of the river and talk with people who dwell informally along the Ping River before beginning to carry out dredging of up to 90 meters in width and 20 kilometers in distance in order to create a deeper water way to prevent flooding in Chiang Mai.

Invaders who have occupied the river banks are being asked to move out; non compliant offenders will be legally prosecuted.

/in

PIANC USA and the Coasts, Oceans, Ports & Rivers Institute today announced that the Dredging 2015 Conference will take place in Savannah, Georgia, October 19-22, 2015, at the Hyatt Regency on the riverfront in the Downtown Historic District.

Organizers expect more than 600 dredging experts from around the world to gather at this fifth technical specialty conference. The format will be very similar to the 2012 Conference in San Diego, with plenary sessions, concurrent technical sessions, short courses, tours, and a large industry exhibit hall.

“More than 200 of the top dredging experts in the world will be presenting technical talks at the conference on more than a dozen major topics ranging from dredged materials management to regulatory challenges to working with nature,” said Conference Chair Stephen Garbaciak Jr., PE, ANCHOR QEA, LLC.

Australia: Darwin Harbour Dredging Completed

/in

INPEX Corporation announced today the on-schedule completion of the Ichthys LNG Project’s dredging program in Darwin Harbour in the Northern Territory of Australia.

The program, which began in August 2012, involved the safe dredging and disposal of more than 16 million cubic meters of rock and sand from the harbor to create a deep shipping channel and berthing area for large LNG, LPG and condensate carriers servicing LNG processing facilities at Bladin Point near Darwin.

A separate dredging program for the Ichthys LNG Project’s gas export pipeline has also been completed with dredgers demobilized on July 23.

To date, the Ichthys LNG Project’s extensive public environmental monitoring program has recorded only a few minor impacts in Darwin Harbour, which are in line with original predictions. International dredging, marine engineering and offshore projects contractor Van Oord led the program using some of the world’s largest and most powerful dredging equipment.

USA: Dredging Underway to Reopen Mississippi River Navigation Channel

/in

The U.S. Army Corps of Engineers, St. Paul District, is preparing to reopen the 9-foot navigation channel along the Mississippi River to commercial navigation.

The Corps and its contractors will begin dredging today, July 25, near Winona, Minn., in Pool 6 from river mile 718 to 724. The Corps is already dredging in Pool 4, near Alma, Wis., at river mile 754. High flows from the June floods caused dredge material to fill areas within the channel.

The Corps hopes to have the area near Alma reopened later today, and anticipates opening the area near Winona on Tuesday, July 29 with a 100-foot wide pilot channel. The Corps hopes to widen the channel to 200 feet by August 2.

At this time, the dredged material will be placed at various placement sites along the river. The Corps may need to explore additional material placement options should future dredging requirements become necessary.

Slovenia: Koper Dredging Project in Full Swing

/in

The Port of Koper dredging scheme is moving forward. The second, larger dredger, owned by the Netherlands-based contractor Van Oord, yesterday commenced dredging works aimed at the seabed deepening along the Container Terminal to 14 metres.

By the end of August, the trailing suction hopper dredger Dravo Costa Dorada will remove about 90 Olympic-size swimming pools of sea sediments (silt) that will be pumped to the disposal sites in the port’s hinterland.

For this purpose, a three-kilometre long pipeline was laid over the last weeks. The dredger will operate 24 hours/day.

The dredged material which is temporarily stored in its own hopper is then pumped through a pipeline to the disposal site.

Van Oord commenced the works last week when a smaller dredger started deepening the seabed under the construction of the container quayside which is technically particularly challenging.
