Title
Installing India Mark II Riser Main (Lifting ArmsSpanners)
Introduction
This guide will show you how to pull the riser main from the well using three lifting armsspanners.
This procedure requires four people: one on each of the lifting arms, and one to control the pipe vise. Communication is very important throughout this procedure. If the person handling the pipe vise opens it before everyone is ready, the riser main could drop through the vise and be lost down the well.
