Goliath Crane’ – Crane 32400 at the Newport News Shipbuilding in Newport News, Virginia
In a highly challenging job, Sarens performed the removal of a 2200T old goliath crane in Newport News, Virginia
1
July 2021

Sarens was commissioned in 2019 to demolish a ‘Goliath Crane’ – Crane 32400 at the Newport News Shipbuilding in Newport News, Virginia on the US East Coast, where this crane has dominated the skyline for decades. The operation was scheduled from March 2020 to September 2020. 

The Newport News Shipbuilding site is the shipyard dedicated to the US Navy, building new fleet, and providing maintenance support to the US Navy fleet of aircraft carriers and submarines. Crane 32400 sits over two parallel docks, with a central wall and has a span of 134m, a hook height of 50.5m, and a lifting capacity of 310LT. The total weight of the crane is estimated at 2200T. Access to the crane was fairly limited and the actual work zone restricted to well-defined areas, as the demolition had to take place in parallel with the preparation of the docks for the next aircraft carrier to come in immediately without interrupting the shipyard activities. 

The team had to address the specific requirements of the client:

  • a mandatory background check for any employee - which takes 4 weeks
    foreign nationals can only bring in devices without camera’s - a challenge to find a phone or computer without a camera
    foreign nationals have to be under permanent escort while on the shipyard  
    The low ground bearing pressure for the tower system on the dock floor was a challenge and no support on the center wall was restricted. Sarens engineering team worked around the challenge and decided to deploy: 
  • The newly developed SMLT 5800
    SCT tower
    Miscellaneous steel beams/girders/braces
    Eight 450T Strand jacks
    One LR1600
    One LR1400
    LTM1250
    SPMT 48L
    2 Barges  
    The combination of the load spreading and actual loads resulted in a free standing 8 tower set-up with a  combination of the SCT (Sarens Climbing Tower) on a 24m tall base of the SMLT 5800 (Sarens Multi Lift Towers). The towers were then topped off with 8 strand jacks of 450T.
  • Early March 2020, a ship was loaded in Ghent, Belgium with the tower system and an LR1600.
    An LR1400 was shipped from South Africa and
    An LTM1250 from The Netherlands.   
    In the last weeks of March, the equipment arrived directly at the shipyard. The site management was decided to be taken up by the US workforce and the Sarens Global Projects team. Due to Covid-19 travel restrictions the global team virtually assisted the operations on the jobsite. 

The demolition of the 32400 Goliath Gantry Crane began in August 2020. After cutting the boogies loose, the 32400 crane was crane lifted and the boogies moved out using the crawler cranes. The boogies were loaded on SPMT and transported to a staging yard to clear space. In 3 more steps, removing the sill beams, the lower leg sections, and the upper leg sections, the main girder was lowered to the ground level. Every step ensured that the crane was secured against high winds due to Hurricane Laura. 

Once the main girder was lowered down, adequate load spreading was installed to set down and release the strand jacks.  Immediately the lifting system was dismantled and assembled for the next phase of the demolition. Simultaneously, the available crane parts including the boogies, sill beams, and leg sections were loaded-out on the barge using SPMTs and transported 10 hours upstream where they are offloaded and set down on the staging area to be finally scrapped. 

As the lifting system was completely dismantled, both docks were filled with water.  In each dock, a barge equipped with supporting girders was positioned under the main girder. Both barges were ballasted to take the load of the main girders. Finally the main girders were cut in the middle and each of the half-girders rotated 90 degrees on the barge and set down for evacuation to the staging area for scrapping.

According to Steven Sarens, Senior Vice President, North America, “It was a truly fascinating experience to be able to walk around the site with a huge historic importance. And not often one gets a chance to get close to an aircraft carrier!” He added, “It is needless to say that the onsite restrictions due to the aircraft carriers and submarines did add an additional challenge to the operations”. “Our meticulous planning and execution made sure that the demolition of the iconic crane was completed smoothly and within the mentioned timeline.”
