BOP Lifting & Handling Ring Frame – New
Rig Manufacturing has designed and engineered our own in house BOP Lifting Ring frames that are manufactured for many different working load limits. These BOP Lifting Ring frames are an in-expensive way for rigs to add a safer and easier way of handling and installing their BOP stack on each well. By using our BOP lifting ring you will not only improve rig safety, but you will also not have to modify your BOP stack at all to accommodate our Lifting ring frame. It is designed to fit around under your annular and lift the BOP stack without having to attach or weld anything to the BOP stack. Once the BOP stack is installed on the wellhead the BOP lifting frame can also be used as a secondary safety tieback anchor for the BOP stack.
These BOP Lifting rings are engineered with a 2.0 DAF (Dynamic Amplification Factor). The BOP Lifting Ring is a two-piece frame that will wrap around the BOP stack assembly on the annular bottom flange area supporting the stack during a lift. Two lifting lugs located at 180 degrees from each other are used to connect to BOP lifting hoists. We can also install four (4) centering lugs for Offshore applications that need to center the stack.
The assemblies are pull tested for more than their WLL and Mag partical weld tested after. These pull test and NDT reports will be included in the RMC data book along with MTR’s. These data books will also include FEA Animation (Stress/Strain) Analysis performed by a Structual P.E. Engineer.
Typical Designs we carry are for BOP stacks below. We can design and customize the lifting ring to your custom requirements as needed.
