Offshore oil rigs are located a fair distance from the nearest land so it is essential that the oil rig is able to support the needs of the workers. For this reason oil rigs
will have a desalination plant to purify the salt water converting it to fresh water for cooking, drinking and, washing and cleaning purposes. Usually rigs will have two
systems for redundancy incase one fails. It is just so that in this case one of the units had failed.This meant that the rig only had the use of one system. Its
replacement was essential should the other system fail. Unfortunately whilst this unit was out of service the other unit was working hard. This posed a problem for the rig operator. The unit had to be changed without affecting the operation of the other unit or affecting the water supply to the rig. In order to replace this unit sections of pipe had to be relocated so the old unit could be removed and the new one installed. APS were approached by the The Wood Group to help
them identify a solution that would help to solve the problem.
APS worked closely with the Wood Group and it’s engineers on the oil rig to determine the best solution for this scenario. After much discussion It was decided that the use of the mechanical linestop equipment would be the best course of action. With the mechanical linestops in place the rig engineers were able to remove the required sections of pipe and install the valves further down the line. Once the valves were installed the linestops could be removed and capped off.
The process is highly efficient. It allows for the system to be worked on without the loss of service. The efficiency gains are substantial as it eliminates the need of a shut down. It is not only the benefits of efficiency that this service offers but a real costs saving one too. The costs of shutting down the desalination plant would mean that the platform would have to be evacuated until such time as the system was up and running again. All the while production would be at a standstill incurring substantial costs.
