Keppel Offshore and Marine (Keppel O&M) has delivered the world’s first European Union (EU) Stage V dredger to Luxembourg-based Jan De Nul Group.
Named Afonso de Albuquerque, the ultra-low emission trailing suction hopper dredger (TSHD) was delivered by Keppel O&M through its wholly owned subsidiary Keppel Singmarine.
The diesel-electrical powered dredger is equipped with an exhaust gas filter system and was built by Keppel at its shipyard in Nantong, China, to the requirements of classification society Bureau Veritas.
Keppel O&M plans to deliver the second and third dredgers for Jan De Nul later this quarter.
Designed with a shallow draught and high manoeuvrability, the TSHD is capable of dredging to a maximum depth of 27.6m and has a hopper capacity of 3,500m³.
It has been built to work in confined areas and will be used for dredging loose and soft soils such as sand, gravel, silt or clay.
With the help of bottom doors, the dredged material can be deposited on the seabed or discharged through a floating pipeline to shore and used for land reclamation.
Jan De Nul Group Newbuilding Department director Robby De Backer said: “The Keppel team has demonstrated the capability to provide value-added engineering solutions and excellent execution, which is why we ordered five dredgers from them.”
Keppel Singmarine secured contracts in May 2017 from Jan De Nul’s subsidiary Codralux to build two TSHDs valued at around S$120m ($88.59m).
At that time, Keppel said it was building three dredgers for Jan De Nul, based on contracts secured in July 2016.
Keppel is also building six dredgers of various hopper capacities ranging from 3,500m³ to 10,500m³.
