UK5 - Transparency Notice
Summary of the contracting process

The Harwich Haven Authority has completed its procurement process for the 'Maintenance Dredging' contract, which falls under the works category with a focus on private utilities. The procurement, initiated through a direct award, is deemed an exempt contract under the Procurement Act 2023. This contract involves dredging activities at several key locations in the UK such as the Port of Felixstowe and Harwich approach channel. Suffolk Dredging LLP has been selected as the supplier for this project. Key dates include the standstill period ending on April 13, 2026, and the contract period running from April 17, 2026, to April 17, 2031, with potential renewals extending to 2033.

This tender presents significant opportunities for business growth, particularly for enterprises involved in dredging and pumping works. While the contract itself has been awarded to Suffolk Dredging LLP, there are prospects for sub-contracting and collaboration in areas such as dredging innovation and environmental schemes. Companies specialising in dredging technologies, sediment management, and coastal conservation could find opportunities in this tender due to the innovative Tiamat dredging system and associated research activities. The nature of the tender, focusing on development and efficiency gains, makes it particularly suitable for firms that can offer cutting-edge technological solutions and services in the dredging sector.

Procurement Information

This award is not a direct award but rather will be an award of an exempt contract under Paragraph 6 of Schedule 2 of the Procurement Act 2023. This award will grant a utilities contract to an affiliated entity falling within the definition of a group undertaking of Harwich Haven Authority under section 1161(5) of the Companies Act 2006. For at least three years following the contract award, at least 80% of the total turnover of the group undertaking deriving from the supply of goods, services and works will derive from works for the contracting entity. This calculation has been reached using credible business projections in accordance with regulation 42C of the Procurement Regulations 2024. Therefore, this award will qualify as an exempt contract. This notice is issued voluntarily to promote transparency and inform stakeholders that the contracting entity intends to rely on the exempt contract provisions. Harwich Haven Authority (the Authority) is one of the UK's leading trust ports. A core activity of the Authority is maintenance dredging, enabling the world's largest container vessels-up to 17m draft-to call at our ports, a capability unmatched by any other UK container port. To perform the maintenance dredging more efficiently and sustainably, whilst simultaneously reducing costs by 30%, the Authority has invested several million pounds in developing new innovative dredging technology that we call the Tiamat, which has over 140 patents granted around the world. To fully commercialise and further develop the Tiamat, the Authority has decided to set up a majority-controlled LLP with Boskalis to undertake further investment in dredging innovation, research and perform the Authority's maintenance dredging requirements.
