Date posted: 15-05-2017
Around £100 million pounds has been invested in the development at Portsmouth Navy Base, dredging the harbour and construction works on Middle Slip Jetty in preparation for the arrival of the new aircraft carriers. These will be bigger than anything before, and so everything which services them needs to be up scaled in order to meet the requirements of these vessels. This programme upgrade has confirmed the future of the Portsmouth Naval Base for the next 50 to 80 years. It is now the only port which can fully support HMS Queen Elizabeth and Prince of Wales.
The Queen Elizabeth Class (QEC) Base Porting Infrastructure Project saw the demolition and replacement of the 1920's and 1970's sections of the Middle Slip Jetty, the addition of two new fender spacer units, installation of navigation aids and refurbishment and upgrade of the existing jetty and berthing facilities. The main apron of the jetty is due to be christened 'The Princess Royal Jetty'.
MMC Diving Services works included underwater dredging cutting and burning, debris removal and the installation and then wet welding of 408 Anodes. Works also included NDT thickness testing and pile wrapping the top of the 364 piles with the Denso Seashield 2000 SD from under the soffit to splash zone approximately 2.2 meters.
MMC also provided work boats safety vessels, a multicat, and crew transfer vessels to help complete works on the navigation aids planted in the harbour. These beacons raise out of the water 150ft high, there job is to help the captain and bridge team, pilot to bring the carriers safely into harbour and guide alongside the quay.
Our rope access and confined space teams worked closely with our diving division, with many of our personnel being cross trained, allowing us to undertake both diving and access services with the same team of personnel on-site. This mix of services offers our clients greater flexibility and efficiencies in both time and cost, removing the requirement for numerous contractors onsite. Our teams can be relied upon in the most hazardous of environments which have regularly resulted in time and cost savings for our clients.
