Time To Load:
Piling in the middle of nowhere
Tight Site, Tight Timescale
England has some of the most beautiful countryside in the world, especially in rural Cumbria. With that beauty comes challenges, and when a river’s banks are damaged by the flow, their repair leads to a specialist logistics challenge.
So how do you repair a riverbank when there is no access for the heavy plant? By river. Our client is a specialist in the provision of floating modular platforms. They requested Harlyn to assist in the engineering to operate an excavator in this challenging location.
The site is surrounded by the river on one side, houses a railway, cliffs and a road with a small bridge.
The river had very low water levels which meant the distance from the bank to the edge of the pontoon was quite large and so a larger reach was required.
As such, a long reach excavator was specified for the project. However, long reach and large capacity means high and heavy.
Harlyn provided all the required engineering to load and operate the long reach excavator, complete with its vibro hammer suitable to drive the piles.
Roll On - roll off
Harlyn designed modifications to existing equipment and assisted in the procurement of steel mats to allow the safe loading of the Excavator. These mats were specified to reduce the incline angle the excavator had to track on and off of the pontoon. As well as the linkspans, we assisted the client by specifying and operating the ballast pumps to keep the barge level during the loading.
We provided advice and calculations for the operations of the mooring system for both the loading and when in operation.
In order to maintain safe and efficient operations, Harlyn developed clear operating envelope drawings showing the allowable slew areas and corresponding outreaches to effectively communicate to the operator safe operating limits of the combined system.
Site attendance and management
Our team were onsite, working with our client to ensure safety throughout the operations. By being onsite, we could cross check drafts, loads and layouts to ensure all is as planned and to alert when the operations divert from the plan at hand.
Successful project in a beautiful landscape
In the end, our client was able to complete the project without damaging the beautiful Cumbrian countryside.
