Royal IHC has completed the upgrade of the underwater pump and jet water system on trailing suction hopper dredger (TSHD) Volvox Terranova for Van Oord.
The renovation involved among others a complete engineering package. This package included a plan of repairs for the ship’s hull and modifications to accommodate a jet pump unit and the frequency drive of the new submerged dredge pump unit.
The delivery of a 1,700kW jet pump unit and the modification of the complete suction tube was completed on schedule.
Furthermore, the underwater pump unit was redesigned in order to accommodate a new 6MW submersible pump unit, including an e-motor delivered by the customer and a new IHC high efficiency dredge pump with Curve® technology.
Wouter Kruijt, Executive Director Services for IHC , said: “ We are proud to have completed this challenging project in just ten months. This was made possible by the close cooperation between Van Oord and the IHC project team, as well as the timely production of newly designed equipment and the re-use of strategic spare parts from Van Oord. ”
Jaap Bakker, Manager Design & Construction at Van Oord added: “ This was a successful project and delivered on time. The renovated equipment means we can operate the vessel more efficiently and improve her dredging capabilities.”
This upgrade is part of the reinstatement of the TSHD being undertaken in Singapore. The refurbished key components will be transported from Kinderdijk to Singapore, where they will be installed onboard the vessel.
