Polperro Sewage Treatment Scheme

Case Study Overview

Red7Marine were approached to provide various access and craneage solutions to allow the construction of a new sewage treatment centre to be constructed in the small Cornish village of Polperro. The village itself had very poor road access meaning all works and deliveries had to utilise marine plant.

  • Date: June 2010
  • Programme Duration: 2 months
  • Project Number: 2244
  • Value: £366,000
  • Client: Dean & Dyball Civil Engineering
  • Principal Contractor: Dean & Dyball Civil Engineering

The Challenge

The solution proposed was the utilisation of Red7Marines Haven Seaway Jack Up Barge to house a 100 tonne crawler crane which in turn would be used to build a temporary jetty. This crane was then to be tracked from the jack up onto the jetty, as illustrated above, allowing it to be used for the duration of the build.

Initially Red7Marine had to perform a dive survey, from the Haven Seaway, of the area to ensure the foundation fixings of the temporary jetty were suitable. The barge was then employed for craneage operations, lifting various components of the temporary jetty from Red7Marine’s 16m by 8m modular supply barge, which was towed to and from the loading area in Par Docks by Red7Marine’s Haven Supporter Stan Tug.

Red7Marine’s specialist plant was utilised to provide the client with the safe and efficient access solution required to deliver the new sewage treatment works at Polperro.
