BALLASTING EXPERTISE ADDS WEIGHT TO FORTH FLOAT OUTS

Posted: Thursday 14th April 2016

Hire specialist, Sykes Pumps, is playing a vital role in delivering Scotland's biggest transport infrastructure project in a generation; The Forth Replacement Crossing (FRC).

Once completed later this year, the new road bridge will be the longest three tower cable-stayed bridge in the world, constructed by the Forth Crossing Bridge Constructors (FCBC) consortium using 42,000 tonnes of steel.

Getting all that steel out into the Firth of Forth is a delicate operation and Sykes Pumps is playing a vital role in managing the ballast of the float out operation being delivered by heavy lifting and engineered transport specialist, Sarens.

Sykes Pumps has provided 50 x GP150M diesel pumps for the operation, which involves transferring 7,000 tonne sections of prefabricated steel and concrete deck onto float out barges using SPMT vehicles (self-propelled modular transport).

The company worked with Sarens to calculate the ballast requirements for the load on and load off manoeuvres and has invested in additional fittings and butterfly valves for the pumps to provide dual suction and discharge, reducing the number of pumps and personnel required on site and optimising efficiency for the ballasting operation.

Explains Alister Smith, project manager at Sarens: "We are using two load out vessels for the project, each with 25 pumps from Sykes.

"We have worked with Sykes Pumps several times before and were not only confident that they had the fleet availability we needed but also that they could work with us on the ballast plans, ensuring that the water pumped into and out of the vessels' tank compartments is calculated accurately."

Sykes Pumps float outs expert, Richard Box, has worked with Sarens on the ballast calculations and will make weekly visits to site throughout the scheme to oversee the pumping operation and manage maintenance and servicing of the pumps, which is included in the hire contract.

Richard adds: "This scheme will create another iconic landmark at the Firth of Forth in parallel to the existing bridges.

"Our experience means that we were able to advise the client on dual suction and discharge pumping, enhancing the efficiency of the ballasting operation and ensuring the float outs are completed safely in line with the construction programme."
