International Dredging Review

International Dredging Review

Ellicott International has received contracts from the Kingdom of Thailand worth more than $50 million. They will deliver 28-inch and 20-inch cutterhead dredges and associated equipment for use in coastal rivers and harbors. The Thai Harbor Department of the Ministry of Transportation selected Ellicott after a multi-year tendering process.

Ellicott first supplied dredges to Thailand more than 40 years ago.

The Harbor Department will use the dredges to expand Thailand’s export capacity. Trade accounts for more than 40 percent of the country’s gross national product which has been growing at greater than eight percent per year in recent decades. The Harbor Department is responsible for maintaining navigational access to the country’s harbors and is also involved in port expansion projects through land reclamation and construction of new quays.

The 28-inch Super-Dragon TM dredges will feature a 3100hp (2310 kW) hull pump a 955hp (711kW) ladder pump and a cutter with 1006 hp (750 kW.) The dredge is designed to produce 1060 cubic yards (820 cubic meters) per hour of coarse sand through a 2000-meter pipeline. The dredge will have a spud carriage system pioneered by Ellicott capable of exerting 44 tons (40 metric tons) of crowding force. There are quarters for a crew of 10.

The 20-inch Super-Dragon will have a hull pump of 1710 hp (1275 kW) and 250 hp (186 kW) on the cutter. It also has a spud carriage and quarters for 10 people. The spud carriage enhances dredging efficiency by reducing spudding time.

The units will be delivered to several locations along the country’s 2000-kilometer coast which the Harbor Department has divided into four regions of operational responsibility. Ellicott will deliver a tender boat as a support vessel for each new dredge: a twin screw 1004 hp (750 kW) model for each 28-inch dredge and a single screw 540 hp (403 kW) model for each 20-inch dredge.

The dredges and tender boats will be delivered in 1999.

As of January 23 Ellicott had 25 dredges under construction not including a number of Mud Cat auger dredges. Ellicott’s new web site address is:
