Project was awarded to Goss & Balfe for the installation of over 40,000 weld inches and 13kms of piping.
Of significance on this project was that our client faced inordinate challenges beyond his control in completing the piping design and stress analysis. This had the effect of radically altering the original planned release and sequence of ISO’s for manufacture which led to numerous changes to the pipe routing leading to serious delays with the free-issue material.
Collectively we managed the initial site resource allocation by producing and installing ‘early opportunity’ works and completing the OBL’s. As momentum was gained with material supply and the issuing of ISO’s, we progressively ramped-up our resources in order to meet Omnia’s extremely tight delivery schedule.
The project was completed in record time and the relationship between Omnia and Goss & Balfe ensured a remarkable outcome without a single dispute being raised.
The largest modularisation project ever undertaken by Sappi involves the manufacture and erection of 28 individual modules.
The modules are fully assembled at a site laydown before being transported to their final position on site on an SPMT vehicle where the interconnecting welds are performed.
Our in-house PWHT team are fully equipped to conduct the pre and post weld heat treatment for the heavy bore Cr piping and 100% X-ray is being carried out to conform to the hydro-test waiver obtained by the client.
The fabrication and erection of 8,6kms of steam, condensate and other process piping, tying into the existing Plant ranging from 15NB to 300NB. Despite late access resulting from client restraints, the complex SIMOPS with severe access limitations as well as a significant growth in scope, we achieved a successful completion of the Project within schedule and in less than 7 months from inception.
The works comprised well in excess of 18,000 weld diameter inches.
The scope included the supply of all materials as well as the design and manufacture of several pressure vessels.
Transnet National Port Authority (TNPA) require an upgrade the Port of Durban Dry Dock pumping facilities as the dock is nearly 100 years old and the equipment is effectively at the end of its design life.
This operational equipment primarily consists of 3 main pumps / motors, valves, piping, auxiliary pumps, sluice pumps and associated electrical supplies. The operational system / equipment is mainly used to drain the water from the Dry Dock and pumping water into the sea for the purpose of ship repair and maintenance in the Dry Dock.
