PD Ports invests £23m in a new, state of the art dredging vessel, according to the company's release.
The 71m long dredger, which has already been named the Emerald Duchess following a competition among PD Ports employees, will arrive at Teesport next summer.
The vessel has been designed and built by renowned Dutch shipbuilder Neptune to an exacting specification, with the help of PD Ports’ technical experts, to ensure it can carry out its tasks on the Tees to the highest environmental and safety standards.
Currently under construction at a shipyard in Poland for commissioning, ahead of trials in the Netherlands in 2024, the Emerald Duchess will replace the Cleveland County, which had served the Tees under PD Ports’ conservancy team for 50 years.
The new vessel has been ‘future-proofed’ with a number of bespoke design features that will eventually allow carbon neutral operations.
Fitted with an innovative intelligent power management system, the Emerald Duchess can swap between power from a battery pack equivalent to 10 Tesla cars and fuel made from hydrotreated vegetable oil (HVO), also known as renewable diesel.
It is also ready for future innovation, with hatches above the engine room to allow power units to be swapped out for modern fuel cells as the technology matures, using methanol or ethanol fuel.
Extensive modelling, using computational fluid dynamics, has taken place to create a hull that is as refined as possible while moving through the water to minimise fuel consumption.
The investment in Emerald Duchess, which will be able to carry 2,500 tonnes and hold up 2000 cubic metres of dredged material, is a further step in PD Ports’ commitment to be Carbon Neutral by 2027, supporting its ambitions to become the UK’s most sustainable port operator.
As Statutory Harbour Authority (SHA), PD Ports has the powers to dredge to legally agreed levels to allow commercial operations along the Tees and at Hartlepool, creating a safe and consistent passage for vessels of depths up to 17metres.
The method of removing sediment brought into the river by the tides, which is then discharged into designated areas off the coast, is closely monitored and regulated by the Marine Management Organisation with a process that has been in place for more than 50 years.
