Second phase of Lerwick Harbour dredging project to commence

The second phase of a major dredging project at Lerwick Harbour in Scotland is set to get underway mid-month following successful completion of an initial phase in July.

The resumption of dredging by Boskalis Westminster follows the arrival backhoe dredger, Magnor, today.

The latest contract award was led by project managers, Scottish-based Arch Henderson, part of international consulting engineers, Haskoning. The project is supported by Bank of Scotland and Scottish Government agency, Highlands and Islands Enterprise.

Scott Joyce, relationship manager at Bank of Scotland said, ‘It’s great to see the Magnor arrive in Lerwick – a real milestone in what is a hugely important project. These upgrades will help attract large energy and decommissioning projects, while also opening up new opportunities for fishing, cruise and renewables.

‘We’re pleased to be working alongside Lerwick Port Authority on a project that has the potential to drive long-term benefits for the port and Shetland’s wider economy.’

First phase completed successfully

The initial soft dredge phase at the Shetland port was completed on time and on budget, with trailer suction hopper dredger, Shoalway, departing on July 21.

For the second phase of hard dredging, Magnor is accompanied by two Union support tugs, Onyx and Topaz, the split hopper barge, Terraferre 501 and a survey vessel, Aramis.

The dredger will operate in Dales Voe and Gremista basin adjacent to Mair’s Pier, as well as the North Ness Channel.

Project completion expected in 2026

Capt. Calum Grains, port authority chief executive said, ‘With excellent progress made, the project is scheduled for completion in February 2026, enabling larger vessels to use the harbour and benefitting a range of sectors, including pelagic fishing, cruise and energy…’

Soft seabed materials and hard rock removed in the two phases is expected to total 450,000 cubic metres, with disposal north of the island of Bressay.
