Construction on the dredger commenced in January this year and is scheduled to be completed by the end of July 2016.

The 167.5m long TSHD with a capacity of 21,028m³, is fitted with two suction tubes, each with a submerged dredge pump, to ensure efficient dredging.

The suction tubes, with an inside diameter of 1,200 / 1,100mm, can dredge up to a depth of 40-60m while the starboard suction tube can be stretched to a depth of 90m.

The two inboard dredge pumps are used for shore discharging and rainbowing. The 31m wide and 12.2m deep TSHD operates at speeds of 16.3 knots, and can accommodate 45 onboard.

The vessel’s architecture and construction conform to the requirements of the China Classification Society (CCS).

The highly automated TSHD will be used by GDC for capital dredging and land reclamation jobs globally.

"The very long-lasting relationship between GDC and IHC reflects the mutual trust and appreciation between the two companies."

Jun Yang 1, which is the 19th vessel IHC is building for GDC, will be the largest of its kind in China.

IHC executive director Arjan Klijnsoon said: "The very long-lasting relationship between GDC and IHC reflects the mutual trust and appreciation between the two companies.

"This has resulted in extremely close cooperation on the construction of the largest TSHD in China."

IHC launched two more TSHDs, 5,500m³ Ilembe and 1,840m³ Mahury, earlier this year.

Ilembe is being built at the Kinderdijk yard for Transnet National Ports Authority, and Mahury for Baggerbedrijf de Boer – Dutch Dredging in Varna, Bulgaria.
