· What is a Dynamic Positioning System (DPS)? A system used to monitor the natural occurrences that take place offshore and aids ships to maintain their position in the deep sea by pinpointing wind and wave data. · Why is DPS Used? It is generally used in research ships and drilling vessels which have to operate in the deepest parts of the ocean and sea where wind and waves are continuously altering. Ships enabled with DPS are independent of anchors and other supporting systems. DPS enables the use of pushers and propellers to keep the ship on course and steady rather than get carried away by the fluctuating wind and waves. · How Dynamic Positioning Ships Work? The system contains a control panel which notes the wind and wave fluctuations and accordingly sends appropriate signals to the propellers to enable the ship to maintain its course. · There are three levels of Dynamic Positioning depending on the type of the ship: -Level I DPS Is used for ships whose off-course drifting will not have any impact on the life of the crew or any marine creatures. This system does not have any advanced tools that ships with the other two levels require. -Level II DPS Is built on a ship whose off-course veering may cause serious problems. A Ship enabled with a Level II DPS contains high-end computer applications and diving watercraft in case the ship encounters any major problem in the deep sea. -Level III DPS Contains similar equipment as Level II but with a back-up system at some other location. The aspect of back-up is important because it will act as emergency in case the main system gets destroyed due to any water penetration or occurrence of fire or short circuit or any other inadvertent casualty. Generally, oil tankers which drill in the deep parts of the ocean are equipped with Level III DPS.

Here is a very interesting introduction on Dynanic System Positioning it helps keeping our vessels in position, it’s particularily important during offshore operations when attempting the deployment of Ocean Data Buoys or when a vessel is resuplying an offshore rig for example.

🚀How We Collect Data ( Depth ) under Sea Water 🚀 🔶The beginning of hydrographic surveys can be traced back to fishers tying a weight to a rope and seeing how far it took to get to the bottom. Thankfully, technology has improved so that factors such as water movement do not affect a survey’s accuracy. 🔸The primary resource survey crews use is sonar, which is a system of detection that uses sound waves to bounce or “ping” off of objects to determine their distance when they reflect back. Two of the most commonly used types of sonar in surveying are: 🔷Single-beam sonar uses a single transducer to transmit and receive pings from a specific location in the area. 🔷Multi-beam sonar uses multiple single-beam transducers to cover a wide area rather than focusing on a single point. 🔸A good way to understand the purposes of each sonar is to consider them as a flashlight and a floodlight. A flashlight enables you to focus a large amount of light on a very specific point, while a floodlight enables you to see a wider area, but with less specificity than the flashlight. In the same way, a multi-beam will give you a general picture of a large area, and a single-beam allows you to hone in and get the details of a single spot. #survey #multibeam #MBES #Hydrography #surveyboat #watersurvey #Echosounder #AhmedSameh #dredging #Dredgger #APEX #marine #Naval #vessel #Singlebeam #Marine #Surveyour #NavalSurvey #Surveyor #DataProcessing

A sonar image can provide a flood of very interesting information such as the geometry of a subsea cable as well as its sedimentary environment. Thanks to the versatility and stability of the SEA360 AUV to offer us data of such quality. #AUV #Marine #Sea360 #survey

Dynamic Positioning System (DPS) is an advanced technology employed to oversee natural offshore conditions and assist vessels in preserving their position in deep sea environments by precisely tracking wind and wave data. 🔹 Purpose of DPS: DPS finds its primary application in research ships and drilling vessels navigating the most remote and challenging oceanic depths, where wind and waves exhibit constant variability. Unlike traditional anchoring methods, ships equipped with DPS operate autonomously, free from reliance on anchors or auxiliary systems. By leveraging pushers and propellers, DPS ensures vessels maintain their intended course and stability amidst the ever-changing forces of wind and waves, enhancing operational efficiency and safety. #MaritimeIndustry #Shipping #MarineTechnology #MaritimeInnovation #OceanTransportation #PortsAndTerminals #MarineEngineering #MaritimeLogistics #MaritimeTrade #NavalArchitecture #Seafarers #MaritimeSafety #Oceanography #MaritimeLaw #MarineEnvironment #MaritimeEducation #MaritimeHistory #Shipbuilding #PassionForTheSea
