What counts as a marine installations tender?
Marine installations tenders cover the installation, replacement and maintenance of subsea cables, moorings and other fixed marine infrastructure procured by UK and Irish public sector buyers.
Where are marine installations contracts advertised?
Stotles brings together marine installations tenders and contracts from 100+ portals into one search, so you do not have to check each portal separately, and you can set alerts for new opportunities across the UK and Ireland.
If you want to search the government portals directly, Find a Tender carries higher-value contracts across the UK and Contracts Finder carries lower-value contracts in England. Public Contracts Scotland, Sell2Wales and eTendersNI cover Scotland, Wales and Northern Ireland, Ireland's eTenders covers Irish public bodies, and many councils, NHS bodies and housing associations publish on their own e-tendering portals such as ProContract. Subsea cable work is often called off from existing frameworks as annual campaigns or fault repair, while marine energy deployments are tendered as one-off contracts.
What do you need to bid for marine installations contracts?
Marine works need a marine licence from the Marine Management Organisation or the equivalent regulator, and site work brings duties under the Construction (Design and Management) Regulations 2015. Tenders usually set minimum insurance cover, check financial standing and ask for evidence of similar contracts at selection stage. Under the Procurement Act 2023, suppliers can be excluded for certain criminal convictions, insolvency or failure to pay tax.
Are marine installations contracts awarded as frameworks?
Some marine installations work is procured as call-off contracts under existing framework agreements, and other requirements are tendered as single contracts.
Who buys marine installations contracts?
Electricity network operators and marine energy developers procure marine installations work as part of subsea cable replacement, mooring system upgrades and marine energy device deployment.
How do I find marine installations contracts before they are formally tendered?
Read capital programmes, planned maintenance schedules, estate condition surveys and early market engagement notices, which show marine installations work coming due ahead of a notice. On Stotles you can track those signals and the buyers behind them, then follow a notice from pre-tender through to award.
What CPV codes cover marine installations tenders?
Marine installations have no dedicated CPV code, and subsea cable and mooring work is classified under general marine and electrical construction codes.
