HHA to implement ncos ukc systemThe Trust Port is set to further bolster its impressive safety record by implementing DHI Seaport’s NCOS ONLINE Dynamic Under Keel Clearance (UKC) system.
Harwich Haven Authority – responsible for managing the waterways into two of Britain’s busiest ports – has signed a deal with DHI Seaport to implement the technology across three phases.
It is hoped that the technology will help boost the port’s capacity as it looks to continue welcoming the world’s largest and deepest-draught vessels exceeding 17m.
The system is currently being built, with the first phase expected to go live before the end of this year. Louise Fennessy, Deputy Harbour Master (Pilotage) at HHA, said: “It is hugely exciting to introduce this world-leading technology to HHA.
“We continue to welcome the world’s deepest vessels to our ports thanks to initiatives like our 2023 Channel Deepening Project – helping the Haven stand out as the UK’s premier place for container trade. This is the latest step in continuing this progress.
“This new system will help us more safely and accurately determine the UKC required to cater for these larger vessels, further minimising disruption and increasing reliability for our customers.
“We look forward to continuing our work with DHI Seaport as the implementation process progresses.”
DHI Seaport is currently developing a detailed model of the Harwich harbour area and its approaches – which will also bring together live data on tides, swell and wind alongside the latest bathymetrics.
The system will be integrated with HHA’s existing VTS Kongsberg system, enabling vessel data to be automatically transferred into NCOS ONLINE.
Training will be provided by DHI Seaport to HHA’s VTS duty officers and pilots throughout the first four-month period.
DHI Seaport representatives will also be on-site for about one week each month to provide support, answer questions, and assist with the implementation process.
Managing Director of DHI Seaport, Simon Brandi Mortensen, said: “Harwich Haven Authority is, in our view, already leading the way by adopting cutting-edge technology to improve their port operations.
“DHI Seaport is deeply honoured to have been chosen as their trusted digital systems provider for dynamic UKC and optimised vessel traffic scheduling at the Port of Felixstowe.”
Stage Two has been earmarked for Q1 2027 and will include a gradual, carefully managed transition from the current static 10% UKC requirement to a dynamic UKC requirement within the harbour area.
Stage Three will see Ipswich integrated into the system, followed by a final integration stage across the remaining HHA ports.
