Itajaí and Navegantes Port Complex receives new dredger

On March 15th, a new hopper dredger arrived at the Itajaí and Navegantes Port Complex to reinforce dredging activities in the region. The vessel was operating at the Port of São Francisco do Sul (SC).

The Lelystad hopper dredger, a trailing suction hopper dredger (TSHD), operates by sucking sediments at the bottom of the river through two tubes, one on each side. It was built in 1986 in the Netherlands and is 136.97 meters long and 26.07 meters wide. -With a gross weight of 13,200 tons, it has two 9-cylinder Wartsila diesel engines. Its dredging capacity is 10,000 cubic meters per trip.

The dredging services are part of a contract between the port authority and Van Oord (the company responsible for maintaining the operational draft of the Port Complex of Itajaí and Navegantes, through an active 5-year contract (2019-2024), to maintain the operational draft at 14 meters in depth.

In January, the dredger was already operating in the port complex of Itajaí and Navegantes to reinforce dredging after the large volume of rain in the Itajaí valley that caused sediment to collect in the bed of the access channel and near the entrance to the jetties.

The Lelystad hopper dredge has the capacity to dredge 10,000 cubic meters per trip and will be making an average of 10 to 12 trips per day, dumping the sediment about 5 nautical miles away (about 10 kilometers).

In addition to the Lelystad hopper dredge that arrived on the 15th, the Itajaí and Navegantes port complex is also using the German dredger “NJörd”. Arriving from Germany on February 21st, it began operating on March 3rd. It is a water-injection dredge and has three times more power than the Odin dredge, which was operating in the complex and has been replaced by NJörd. It is working daily to maintain the channel and there is currently no defined departure date.

The Lelystad hopper dredger will do all the dredging services along the access channel of the port complex up until the exit of the jetties, in front of the evolution basin 01 (in the areas of APMT, public pier, and Portonave), and also in the northern region of ​​the new evolution basin (basin 02).
