GDC’s New Dredger Launched in The Netherlands

The naming and launch ceremony of the trailing suction hopper dredger (TSHD) Jun Yang 1 took place on Saturday, December 19, 2015 at Royal IHC’s shipyard in Kinderdijk, The Netherlands. The dredger is being built for CCCC Guangzhou Dredging Co., Ltd (GDC), and the ceremony was performed by Li Wen Ci, the wife of H.E. The Ambassador of the People’s Republic of China in The Netherlands.

IHC noted it has a long-standing relationship with GDC, and both companies cooperated closely in the design of the dredger. At the time of delivery, it will be the largest vessel of its kind in China, and will enable GDC to carry out capital dredging and land reclamation jobs on the international market in an efficient way, the shipbuilder said.

The Jun Yang 1 is equipped with two suction tubes, each with a submerged dredge pump. Both suction tubes have a dredging depth of up to 40-60 meters, and the starboard suction tube can be extended to a dredging depth of 90 meters. Two inboard dredge pumps have been installed for shore discharging and rainbowing. The TSHD has a high level of automation, designed and supplied by IHC.

This is the 19th vessel built by IHC for GDC over the last 40 years. In four decades IHC has developed a portfolio of dredging vessels ranging from TSHDs to cutter suction dredgers and wheel dredgers. These dredgers were constructed either on the IHC slipways in The Netherlands, or in partnership with shipyards in the People’s Republic of China.

The contract for the design, construction and delivery of the vessel was signed between GDC and IHC on November 1, 2012. The keel of the vessel was laid on January 16, 2015 at IHC’s shipyard in Kinderdijk. The Jun Yang 1 is scheduled for completion by end July 2016.
