The concept of cable dynamics has been used for many years. It has to do with virtually anything cable related to ensure stability, strength, and reliability. Different materials and different uses can impact the end result and when you are using cables on an oil rig, analysis needs to be conducted.

Training

Understanding the full cable dynamics of a project will make it easier to train everyone involved. The the science of cables can be complex, but when everyone knows the limitations and the range, it will be easier for them to manipulate the rig and work within it. Various forms of analysis can also be used to stage various training scenarios so everyone knows how to make a repair when something goes wrong.

Preparation

You should always be prepared for what’s going to happen on a rig, whether it is offshore or not. There’s a lot that can go wrong and it’s best to know what the various scenarios are. At Stewart Technology Associates, you can order all of the necessary analysis, including anchor analysis so that you have the various numbers and thresholds in front of you. With this documentation, you can go forward knowing that you have done all that you can to prepare for a specific project before going live with it.

Parts Selection

There are various oil rig parts and some are going to be better than others in certain scenarios. By having a firm grasp on the cable dynamics, you can be sure that the cables are chosen based upon the weight and pressure of the environment and that the materials are capable of enduring the heat, salinity, and other factors that will surround them.

Funding

Often, those who are funding an oil rig project want to see all of the documentation as well as all of the costs laid out ahead of time. Most financial supporters are savvy to the gas and oil industry and therefore they know that there are accidents that can happen. Your goal is to take the precautions to minimize accidents and therefore you want to supply investors with as much documentation as you can to show that due diligence has been taken and that cable dynamics has been considered throughout the construction of the rig as well as the entire strategy.

Risk Management

Risk management is another way to benefit from cable dynamics. The more you know about the cables, their resistance, and their overall durability, the more you can minimize risks. Especially offshore, you cannot allow for any injuries or accidents because help is not close by. Risk management is a combination of staff training, preparation, and overall analysis – and is not something that you can forget to do when establishing a project within the gas and oil industry. Stewart Technology Associates can help you every step of the way.

5 Reasons To Take Advantage Of Hydrodynamic Analysis

Hydrodynamic analysis is the study of liquids in motion and more specifically, water. When you are engaging in any kind of offshore project, such as oil drilling or anything else, you have to know how the water is going to behave to be sufficiently prepared. There are five reasons why you want to invest in analysis that you can rely on.

Plan for Worst-Case Scenarios

It’s always best to plan for the worst-case scenarios because it is good for business. If you get out in the middle of the ocean and then suddenly have swells twice the size than what you were expecting, there are going to be problems with your project. Accidents can happen and you can lose equipment and even lose men. Many maritime accidents have occurred as a result of lack of planning and this can be avoided simply by obtaining hydrodynamic analysis.

Have the Right Equipment Onboard

There’s going to be a lot of equipment going onto your rig. The lines and cables that you bring will be able to deal with a certain amount of force. The power of ocean waves can be considerable and you don’t want to encounter issues where a cable breaks when a wave comes through. Knowing more about the power of the waves based upon where you will be will make it possible to acquire all of the right equipment.

Double Check Your Numbers

You may do a lot of the analysis on your own, though it’s a good idea to have a third party crunch them as well. When you are involved in offshore drilling, it’s always a good idea to double check numbers to make sure that all aspects have been covered and you aren’t making critical decisions based on old or inaccurate numbers.

Take Advantage of State of the Art Technology

State of the art technology can be used for obtaining hydrodynamic analysis. At Stewart Technology Associates, Orcaflex is the software used and it is known for providing some of the best numbers regarding various offshore projects, including cable dynamics. This gives you a clear understanding of what you will deal with out on the water to make better judgment calls and prepare everyone involved.

Train Your Staff

Training your staff is a step that cannot be taken lightly and hydrodynamic analysis can be used to help you determine what topics the training needs to cover. You want to talk to them about worst-case scenarios, run through safety drills, and do an array of other things so they are well prepared. Accidents are most likely to happen when the staff doesn’t know what to expect. You cannot afford to go out into the middle of the ocean and lose a team member, especially if it could have been avoided with a few hours of training.

5 Benefits To Single Point Moorings

Single point moorings, sometimes referred as SPM, are floating docks that are used in offshore drilling as well as various other ocean-based projects. There are many benefits to them and can be useful when anchoring is not an option as well as when it is not conducive to going all the way back to shore.

Save Money

There is the opportunity to save a lot of money with single point moorings. When you look at the economics of oil drilling, much of the cost of oil has to do with the cost to actually acquire it. If the rigs have to go back and forth between the shore and the middle of the ocean, a significant amount of fuel is going to be used. The benefit to SPMs is that they can be located at a half-way point.

Save Time

Time is often of the essence when it comes to offshore drilling and moorings are capable of saving a lot of time. Without a mooring, a vessel would have to go all the way back to shore when it requires fuel, to drop off crude oil barrels, or to pick up supplies. The vessels are not known for speed and therefore it can slow a project down considerably. It is always best for business to finish projects on or before deadline and therefore utilizing moorings is good for business. It can be the needed halfway point to save days or even weeks of travel.

Extra Large Vessels Can Use the Moorings

It’s important to understand how a mooring works. Single point moorings are capable of handling extra-large vessels in a better capacity than certain loading docks and even certain anchor systems. This will allow the vessel to pull up to the mooring for a fuel fill up or to load/unload materials. A ship can simply be connected to the buoy using a series of lines and connectors – and the mooring will have sufficient space in most instances to make the connections easy to establish.

High Draft Ships Can Be Moored

A significant amount of hydrodynamic analysis needs to be done on ships to see how the draft, the waves, and various other environmental factors affect them. Single point moorings are capable of working with shifts that catch a high draft because the mooring can be accessed from any side, thus making it convenient for the ship to come up on the side that works best for them based upon the direction of the wind.

Large Amounts of Cargo Can Be Handled

Single point moorings can be built to handle a significant amount of weight. Stewart Technology Associates can determine the load capacities through analysis using state of the art technology. This analysis proves critical so you know whether a mooring can support the amount of cargo that you either need to pick up or drop off.
