Marine Designs Limited – EON – Crew Transfer Pontoons

Wednesday 5th November 2014

Marine Designs Ltd has just completed its eleventh offshore wind related project with the installation of crew transfer pontoons in Grimsby Fish Docks for the EON Humber Gateway Windfarm Project.  The design and build contract involved the construction of 5 x 52t x 6m x 1.1m freeboard concrete pontoon units, steel gangway, which was fabricated by A&P Tees, electrical and water services, pontoon fuel system and a two shore mounted gantry cranes.  Particular features of the pontoons included the use of high quality pre cast concrete made from eco-crete (pre mined aggregates) and top entry service ducts which allow the services to be laid, inspected and adapted easily in the future if required.

 

Drystan Jones MD of Marine Designs said “Every detail of this installation was carefully considered with the client and the result is a really high quality pontoon system that will serve the site well throughout the operating life of the Humber Gateway windfarm”.

 

Last year the company installed a crew transfer pontoon for RWE at its Base Harbour Port in Birkenhead for the Gwent Y Mor offshore windfarm.  That project involved building a pontoon 130m out into the River Mersey so that the crew transfer vessels could access the construction base at all states of the tide and take on fuel from the pontoons.  The berthing pontoons for the project weighed in at 330t with three 40m walkways supported on 12m by 12m 170t concrete pontoons which were restrained with a heavy chain mooring system.

 

To date the company has been involved with the most significant offshore wind operations and maintenance port developments in the Uk and continues to be a leader in the design and build of heavy duty concrete commercial pontoons.

 

Marine Designs is part of the A&P Group which owns and operates port facilities and dry docks in the SW and NE of the UK, providing excellent facilities and proven engineering expertise to the offshore industry.
