Mooring is to four concrete sinkers with mooring wires and shock absorbing chains to the pontoon.Included in the contract is the safe and ecologically compliant disposal of the existing facility. The objective of the project is to replace the existing facility with a new and substantially improved pontoon for the testing and calibration of underwater acoustic transducers and associated apparatus. Overall dimensions of the pontoon are approximately 32.50 metres long and 31 metres beam comprising five hulls each consisting of six (6) modular pontoons supporting a deck of steel grillage construction topped with non-slip glass fibre panels. Safety railings, arranged in portable sections are to be fitted around the perimeter of the pontoon and around both moon pools. Within the pontoon will be two (2) moon pools one about 20.00 metres long, the other around 15 metres, both are 4.20 metres wide over which will be gantry cranes incorporating the test equipment lifting stations.

To starboard forward is a small single storey building for additional office space; aft to port is another small building for use as a garage/store. Suitable rubber 'D' section fendering is to be fitted around the periphery of the pontoon to prevent damage of both the pontoon and the vessels servicing it. Services are arranged from shore to the pontoon and include 400/3/50 AC power supply, telephone and internet. Mooring of the pontoon will be by four (4) concrete sinkers suitably positioned on the reservoir bottom and connected to the pontoon by adjustable length steel galvanised wire ... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/building-delivery-and-installation-of-an-open-raft-facility-ocds-h6vhtk-051d47) ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** planned - **CPV codes:** 44000000, 45000000, 71000000 - **Delivery regions:** UKC, UKD, UKE, UKF, UKG, UKH, UKI, UKJ, UKK - **Delivery countries in notice:** GB - **Contract Period:** 28/11/2025 to 30/11/2026 ## Provenance and Official Sources - **Official Notice:** [Find a Tender notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F024694-2025) - **Last Source Update:** 2025-05-22T11:13:19.000Z - **This document generated:** 2026-10-31T19:07:59.429Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-051d47
