Alatas Singapore was contracted to carry out the 10 yearly overhauls on an NOV and a MacGregor crane onboard an offshore vessel.
The work included a detailed and comprehensive review of the client’s needed before visiting the site. We developed the SOW that ensured the services were completed with both class and best practice standards.
Our dedicated workshop facility in Singapore undertook the complete overhaul of all hydraulic and mechanical components and through our robust supply chain allowed the sourcing of parts to deliver the project cost-effectively.
The client made the most of access to our highly skilled and qualified multi-disciplined service engineers. We put forward cost-effective solutions by having components overhauled in our workshops and further savings were made by using our global supply chain network. Our effective planning meant minimal disruption during dry docking with all work completed safely, on time and budget.
