Throughout the gas and oil industry, there are a number of pieces of equipment that you require. Especially when you are offshore, you need to make sure you have everything that you require before you escape into the middle of the ocean. Cable dynamics must be fully understood so that you establish the best possible rig.
Cables are only designed to hold so much weight and experience so much movement before they fail. When you are talking about the overall effectiveness of your rig and everything else that is going on out there, you cannot afford to have a cable snap or be ineffective at holding the weight based upon the environmental factors.
Analysis can be done prior to leaving out on the rig so that you know what you are up against. Analysis can factor in wind, waves, ocean depth, and various other aspects of being in the ocean so you know how to prepare. The cable dynamics can then be calculated based upon the environmental factors so that you don’t run into issues.
In many instances, you will use single point moorings and various cables within your rig. There are many sites around the globe where you can conduct offshore drilling. The formula that you used the last time may not be the same formula that you use this time because the factors have changed. Many companies try to eliminate analysis a second-time around as a way to save money.
However, you cannot afford to cut corners when it comes to analysis. You need to understand the cable dynamics to their fullest extent so that you have a comprehensive guide to the type of cables, the length, and even the angles in which they are held at so that you have a rig that is strong enough to withstand the waves, the depth of the ocean, and everything else that it is exposed to while being offshore.
There have been too many marine accidents as a result of companies not doing the research. You don’t want to be one of the companies that have an accident simply because you failed to understand the dynamics of the cabling involved with your rig. You need to establish an anchor, a mooring point, as well as various other aspects to be able to avoid movement in the water while being able to do all of the drilling.
A small amount of analysis can go a long way so that you have a firm grasp on what cabling is required and how it is going to impact the overall effectiveness of the rig. This will allow you to get the job done without having to delay because of having to get additional supplies. You will be able to have a smoother operation from the moment you reach your site when you pay attention to your cabling needs.
