Each Thursday we will be sharing a highlight on one of the marine construction projects Red7Marine has completed.
This week is the East Cowes Layby Berth, a £2,000,000 contract Red7Marine delivered in 2019.
To increase the capacity of its ferry service between Southampton and the Isle of Wight, Red Funnel invested £10m in a new freight-only RoRo vessel named ‘Red Kestrel’.
Red7Marine was contracted by Red Funnel to construct a new layby berth in East Cowes in time for the introduction of the new service in May 2019.
Red7Marine delivered the full package of works as Principle Contractor, managed by a professional site team with office support from Engineering, SHEQ and the Operations team in Ipswich.
Red7Marine supplied all key marine plant required to deliver the project in-house and was also responsible for the procurement of all structural steelwork and fender components.
The layby berth was successfully delivered within the time constraints for the project. Fierce deadlines for piling and dredging were set out within the marine license application, all governed by the arrival of the new Red Kestrel Ferry.
All 14no. piles (40m in length, each weighing 30 tons) were driven to level and within tolerance in two weeks to comply with license deadlines. The post installation of 3no. jacket frames onto support collars relieved the requirement for additional in-situ temporary works such as spud piles. This saved time and cost where the piles were driven within tolerance ensuring fitment.
All works had to be planned within a tight site boundary to enable the existing ferry service to operate as normal around the clock. In addition, the 250t Haven Seariser 2 jack-up had to be positioned accurately to avoid a live and redundant sewer main which dissects the site. To overcome this issue, R7M carefully planned the sequence of operations for every barge movement, and also utilised an innovative modular piling gate which had been adapted specifically for the project.
