Harwich Haven Authority; dredging-engineering context, not evidence of Suffolk Dredging mobilisation or contract signature

Harwich Haven Authority confirmed a five-year maintenance award to Suffolk Dredging LLP and a Tiamat licence in July. The March procurement family had been withdrawn for a scope-description correction; its GBP 100 million estimate remains historical.

Owner confirmation follows the March withdrawal

HHA reported the award in July. Find a Tender records the March withdrawal and former estimated terms; Companies House records the corporate chronology and current Harwich office. Programme and fleet sources retain their original dates. Complete signed terms and campaign acceptance evidence have not been obtained.

Campaign allocation controls the engineering work

Harwich's live-port dredging interfaces include berth and approach-channel access, clay, silt and sand management, hydrographic control, licensed disposal and coastal beneficial use. The original notice also described early contractor involvement. Final ordered areas, quantities and delivery roles govern the campaign plan and remain contract-specific.

Evidence conclusion

Current terms and delivery evidence

The July owner statement establishes the award. Exact signature, commencement, current value and extension terms remain undisclosed. The withdrawn notice's 17 April 2026-2031 base term, maximum date of April 2033 and text allowing one or two 24-month extensions are historical and inconsistent. Companies House records HHA's 29 April member appointment and control notification; current members are HHA and Marine Dredging Services (UK) Ltd. The May and June vessel notices retain their dated fleet context, with attribution to the LLP unconfirmed.
