Case Study Overview

Red7Marine was subcontracted by Farrans Construction, to provide specialist marine expertise to install the new pontoon facility at Galloper Offshore wind farm. Red7Marine supported various marine elements of the project including:

  • The installation of bespoke 9no pontoons and two 20m access gangways
  • Coordinating the fabrication, delivery and installation of an intermediate landing platform
  • Load and installation of two 40m aluminium linkspans

At a glance

  • Location: Galloper Wind Farm, Suffolk 2019
  • Plant used: Haven Seaway Jack-up barge / Haven Seavoyager flat top barge
  • What we did: Subcontracted by leading civil engineering firm, Farrans Construction, Red7Marine completed the engineering and marine installation for the new Galloper pontoon facility.
  • Contract Value: £600,000

The Challenge

To comply with consents and licences, the marine piling needed to be completed by the end of September 2019. The contract was only awarded in June 2019 which meant the need for an efficient solution for the project to be executed within the given timeframe.

The team was able to effectively achieve this and received approvals, reviews, recommendations and clearances by the Marine Warranty Surveyor, who acted on behalf of the end users
– all in line with the project programme.

Galloper Challenge

The Solution

The 120m pontoons being installed were manufactured by A&P Group in the North East of the UK before being transported along the coastline to Harwich on a coaster vessel.

Once in Harwich, the pontoons were offloaded and assembled by Red7Marine to complete the installation, adjacent to the newly constructed O&M building.

The gate system together with the permanent works [piles and walkway system] were loaded out through our quay-side fabrication facility in the Port of Ipswich and were transported down the river to Harwich by the Haven Seavoyager for installation by Red7Marine·s team of specialists from the Haven Seaway, jack­ up barge.

  • All site movements were planned to reduce risk and ensure safe operations were conducted, planning around tides and weather windows, reviewing detailed forecasts day-to-day
  • Large scale parmanent works were designed, fabricated (in-house) and implemented on site by Red7Marine
  • The flexibility of our 200t Haven Seaway jack-up barge and Haven Seavoyager flat top, allowed us to deliver the works despite the challenges faced, whilst our team’s determination meant that the project was completed in a timely manner.

The extension is a key part of the River Action Plan to improve TfL’s piers and increase capacity for passengers before 2020. Red7Marine designed and built a custom pile gate for the project. The barge was reviewed to support a 180t crawler crane for piling operations and was then further reviewed with an additional RH28 drill rig on board.
