Wind, waves, and currents exert force on a seagoing vessel, as does the propulsion system. Dynamic positioning (DP) uses the ship’s propellers and thrusters to automatically maintain position and direction.
Position-reference systems, gyrocompass, and vertical reference sensors track the ship’s response to these forces, such as changes in position, direction, and speed. Readings from the reference systems are rolled and panned using the vertical reference sensors. The wind sensors track the movement of the wind and record that information.
One of these mathematical models includes information on how much wind and current drag there is on the ship and where each of its thrusters are located.
This information, along with sensor data, enables the computer to determine the needed steering angle and thruster output for each thruster. This enables activities at sea where mooring or anchoring is not practicable because of deep water, congestion on the sea floor (pipelines, templates) or other issues.
Dynamic positioning can be absolute or relative to a moving object, such as another ship or an underwater vehicle, in that the location is locked to a fixed point on the bottom.
Dynamic Positioning is commonly employed aboard research ships and drilling boats that travel to the ocean’s depths, where conditions such as wind and waves are constantly changing.
The laying of anchors may be a laborious task for a ship’s crew in these types of conditions. A ship equipped with Dynamic Positioning can keep track of the wind and waves and adjust its path accordingly without sacrificing its main objective.
Class 1 DP: This sort of DP system is the simplest and controls the location of the vessel using two or more separate computer systems.
Class 2 DP: This kind of DP system combines sensors like GPS, a gyrocompass, and wind sensors to give the control system precise position data and heading information.
Class 3 DP: This kind of DP system includes redundancy components including triple-redundant computer systems, an independent power source, and additional thrusters. It is designed for high-risk operations in challenging situations, like deepwater drilling.
Artemis: This hybrid DP system, which is frequently used in offshore drilling operations, provides precise position data by utilising both satellite-based GPS and high-frequency radio waves.

On the sides, transverse thrusters for bow and stern tunnel thrusters, azimuth thrusters provided an added advantage for many DP-2 and DP-3 vessels’ main propulsors
DP technology is making efforts to make DP vessels greener. Kongsberg has released the GreenDP system by employing the controller design
Speed is reduced by using 2 engines instead of 4 engines while steaming and SCR to fix at 80% MCR or even lower.
Kongsberg Maritime has launched EcoAdvisor, an intelligent and dynamic decision support system for optimizing a range of vessel operations
A contract for the mathematical modeling of the Amazon, a fast-transit, dynamically positioned (DP2) construction vessel with an ultra-Deepwater J-Lay technology, has been signed by McDermott and Simwave.
Due to the ship’s complexity and the operations performed by McDermott, simulations must be performed by all parties with the utmost accuracy and specialized expertise and abilities.
For installation of the real Kongsberg Dynamic Positioning software (K-Pos DP-2) of the Amazon at Simwave 360 Offshore Full Mission Bridge (FMB) simulator, a power management system is developed in addition to a full hydrodynamic mathematical model with various loading conditions, complex mechanical laying equipment, high-quality 3D visual, and CCTVs.
Recent years have seen rapid expansion in the dynamic positioning system industry as a result of a rise in the number of dynamic position ships such as survey vessels and drilling ships.
Dynamic positioning system demand is also being boosted by advancements in offshore drilling technology and the use of dynamic positioning boats.
Lack of qualified dynamic position operators and system complexity, on the other hand, are limiting market expansion. DPS market development is further hampered by the difficulty of installing and operating the system.
Growing offshore windmill installations, increased offshore patrol vessel numbers, and increased deployment of research vessels are all driving development in the marine dynamic positioning system sector. Marine dynamic positioning systems are becoming increasingly popular.
The rise of international maritime trade and the expansion of activities in the offshore sector also contribute to the industry’s expansion.
The dynamic positioning system market is constrained by the projected slowdown in the shipbuilding and offshore industries, as well as the high maintenance requirements for mechanical components of the system.
Dynamic positioning systems are well-known for their safe and accurate operations, which are widely utilised in the offshore business for a number of reasons. Effective marine operations, energy-efficient systems, and reduced operational expenses and emissions are just some of the advantages it brings.
Deep-sea exploration and rising marine traffic in Asia-Pacific and the Middle East Africa region are driving the demand for Dynamic Positioning systems.
Assuring safety operations and pushing from the government side also helps raise awareness among users. The shipping business is likewise expanding rapidly, providing several opportunities.
From 2012 forward, Volvo Penta will offer its Assisted Docking system as a retrofit option for many yacht owners who have a Volvo Penta IPS (inboard performance system).
The Volvo Penta Assisted Docking system automates a helmsman’s intentions, correcting for dynamic variables like wind and current and assisting the vessel in staying on course.
From model year 2012 for EVCE and EVC2, the docking system is available as an aftermarket retrofit for D6-IPS, D8-IPS, and D11-IPS packages.
The method of retrofitting Assisted Docking will vary by boat, ranging from a simple software update to full conversion kits that include the joystick, Dynamic Positioning System (DPS), antenna, and glass cockpit interface. Customers can meet with a Volvo Penta dealer to see whether Assisted Docking is right for them.
This technology was previously only available on new boats, but they want to make sure that their existing customers can continue to improve their experience on the water as they continue to make boating more accessible, safer, and stress-free.
They will continue to innovate and investigate how digital innovations might create a consistently improving experience for consumers by offering software upgrades for our Volvo Penta IPS system. Assisted Docking is a mix of automatic docking and manual docking that gives the captain more control over the boat during docking.
The Asia Pacific is forecast to lead the marine DP system market over the forecast period. Due to an increase in seaborne trade in the region.
In India, the government is taking steps to promote maritime tourism, leading to a demand for new ships equipped with the latest technologies.
Together with terminal towage company PSA Marine, Wartsila is putting a Dynamic Positioning (DP) system through its paces in the Port of Singapore. The partnership comes after the successful installation of the DP system on the PSA Polaris harbour tug and Wartsila’s IntelliTug project.
This portion of the Wartsila and PSA Marine IntelliTug project has received approval from Lloyd’s Register. The trials are also supported by Singapore’s Maritime and Port Authority. Joystick Maneuvering System (JMS), a new DP, makes it simpler to control tug movement.
The system, which serves as the project’s fundamental technological layer, allows for the transmission of digital navigational instructions to the propulsion systems of the ship.
By 2040, the port of Singapore’s capacity is anticipated to double. Wartsila and PSA Marine are developing and field-testing intelligent vessel capabilities and potential routes for long-term autonomous operations to meet new challenges.
The Global Dynamic Positioning System Market can be segmented into following categories for further analysis.
The DP systems produce a real-time representation of the vessel in the sea, taking into account the wind and currents that affect it, as well as the position and impact of the thrusters.
The computer can use this data, as well as data from instruments like the Gyrocompass, to determine the needed steering angle and thruster power for each thruster in order to position the vessel. The electrical system aboard is critical to the system’s dependability.
There has been recent production mechanism being taken into place for better technological implementations. The most recent development has been the Smart Predict which forms the foundation for moving forward to increased vessel automation.
Typical DP handles station-keeping and basic tracking functions, but as more operators look for the safety and reliability of automatic operations, each phase of vessel control will need to be validated and proven for true vessel autonomy to begin.
Smart Predict is the first step towards the future of autonomous vessel manoeuvring. provides clear indications of potential dangers during ship manoeuvring immediately increasing the safety and efficiency of operations.
This capability is targeted at passenger vessels but brings added safety to any vessel performing challenging manoeuvres.
The advancement has also been placed in the software integration, wherein Manual orders from the coordinated joystick (3 axis); and lastly environmental data from the ship’s wind sensor are all inputs to the control algorithm. Every one of these variables is constantly revaluated to keep the vessel’s course up to date.
It is possible to make better and safer judgments regarding ship handling by giving the operator a glimpse into the future.
This will help prevent situations like those recently portrayed in the media when better navigational aids might have prevented property damage.
Volvo Penta’s goal is to provide boaters with unmatched comfort, convenience, and peace of mind when they are out on the water. The distinctive Dynamic Positioning System (DPS) from Volvo Penta is now available on both its twin V6 and V8 propulsion packages.
DPS is now included in the company’s whole marine leisure package as a result of this development. From 20 feet to 120 feet, all Volvo Penta boats with electric steering will now have access to DPS’s advantages.
Worldwide, the maritime leisure range of Volvo Penta is available with twin, triple, or quadruple solutions enabled by the DPS feature.
Electrical steering is another prerequisite. A software update and antenna installation are also necessary in order to access DPS.
Twin GPS receivers are housed in the antenna, allowing the device to use sophisticated algorithms to detect the position and direction of the boat. The steering angles, gear shifts, and throttle positions are then generated using this data.
Exail, a top supplier of cutting-edge navigation, positioning, and imaging systems, introduces the Gaps M3, a revolutionary, portable, and reasonably priced subsea acoustic positioning system for long-term vessel installation.
Since Gaps M3 is a USBL positioning system without an incorporated inertial navigation system (INS), operators who can rely on their existing onboard navigation systems might choose it as a cost-effective option.
Gaps M3, which is designed for permanent USBL installations, can in fact be connected to on-board navigation systems to give users ongoing access to high-level precision that satisfies all operational needs for survey and Dynamic Positioning (DP) operations.

For applications where it is possible to lower position keeping precision and, in exchange, lower fuel consumption, a fuel-saving mode is available.
The Dynamic Positioning (DP) technology of the corporation will now have improved operability, according to GE Power Conversion.
The most recent version, which has just been released, is more environmentally friendly, better integrated, and most significantly, “mariner friendly.” are returning ship control to the crew.
DP systems have evolved since their introduction almost 50 years ago, both in terms of configuration and functionality. The electrical and propulsion systems have both grown in complexity at the same time that sensors have become more advanced and numerous.
The central computer control of a ship’s positioning system is also more complex, but the fundamental idea behind DP remains the same: to maintain position by using a computer system that receives signals from a variety of sensors to sense the environment, heading, position, and attitude, and then sends commands to the thrusters and propellers.
Overall, it is in charge of the intricate procedures involved in keeping a spacecraft on station, which require a high degree of system automation in order for a single person to control the ship.
As DP systems have become more complex and sophisticated, there is a concern that DP operators may have become more focused on operating the computer than on managing the main duty of controlling the ship’s position, heading, and course.
Kongsberg received an order to install DP 3 system new CrewZer class vessels of US-based offshore marine support vessel operator SEACOR Marine.
MOL Launches Dynamic Positioning System Training Facility. The first training facility in Japan to receive certification from a third party organization for training on special-purpose vessels connected to offshore development
The launch of a training programme for the Dynamic Positioning (DP) System, utilizing a DP simulator erected on the ground floor of the MOL Head Office building, was announced by TOKYO-Mitsui O.S.K. Lines, Ltd. and MOL Marine & Engineering Co., Ltd.
The following training programmes are offered by the training center, which is the first Nautical Institute-certified training facility in Japan. The training center is also able to award the certificates needed to become a qualified DP Operator (DPO).
New dynamic positioning system support was launched by DNV GL. An informational document on failure mode and effects analyses (FMEAs) for the Dynamic Positioning Assurance (DP) system has been released by OCIMF, a global voluntary association that offers knowledge in safe and environmentally responsible hydrocarbon transport and handling.
This attempts to enhance the process of identifying any and all DP system problems and effects. Dynamic Positioning Failure Mode and Effects Analysis Assurance Framework, Risk-based Guidance is a resource for DP vessel owners that has been eagerly expected.
Industry worries regarding the security and dependability of DP vessels were raised as a result of a number of DP events in the UK’s North Sea region.
The UK Health and Safety Executive conducted a thorough investigation into the issue, and it was discovered that supply chain-wide implementation and adherence of the instructions were inconsistent.
By outlining how pertinent information should be given in a specific format, the article attempts to improve the assurance of DP FMEA quality.
The guidance was developed by DNV GL’s Noble Denton marine services in collaboration with a sizable number of industry stakeholders, including classification societies, ship owners, and DP industry organisations.
A wide range of industry stakeholders came together to create this information paper on the assurance requirements for FMEAs, which will increase safety in the sector and act as a tool for bringing different stakeholders’ interests closer together.
The OCIMF information document, in contrast to other initiatives to raise the bar for DP FMEA standards, is not meant to offer recommendations for how to carry out FMEAs for DP systems. Recognised organisations have already published a sizable quantity of guidance on this.
The new standards are different because they offer a thorough set of technical specifications on how to present the main DP system components for vessel audit purposes.
This is done in an effort to enhance things. When providing DP vessel services, OCIMF members who decide to put the information paper into practice shall work to comply with its demands.
During crucial offshore activities, having faith in a vessel’s station holding abilities and dependability can greatly lower risk.
Customers with smaller vessels in the offshore support and mercantile markets have access to a structured and standardised package through GE Marine Solutions’ launched Sea Lyte dynamic positioning (DP) technology. System complexity decreases with less hardware included, which lowers cost.
It offers flexibility to accommodate and integrate with current or pre-selected sub-systems on board ships because it can be fully integrated into one package or utilised separately with third-party technologies.
SeaLyte offers a user-friendly touch screen with high-resolution graphics that may be used with external subsystems from other companies.
With manual and automatic position control, heading control, joystick manoeuvring, and a user-friendly interface to ships’ systems and reference equipment, the SeaLyte DP System is an automatic position and heading control system.
Marine dynamic positioning system is vital for the offshore vessels so that a small envelop of position is maintained. Drilling vessels, diving support vessels, supply vessels, floating, production vessels, storage vessels, and offloading vessels (FPSOs) are some of the ships equipped with dynamic positioning systems.
Dynamic positioning (DP) systems enable ships to maintain their position and heading automatically. Originally, of interest to the offshore oil industry, DP has become a popular technology for a wide range of vessels from cruise ships and flotels through to cable-laying ships, cranes, and supply vessels of all types.
Kongsberg is one of the major developer of dynamic positioning system in the marine and naval requirements. It has produced varied system classification and technologies as part of emerging requirements of fulfilment in the market. GreenDP® control, created by Kongsberg, cuts fuel usage and CO2 emissions by up to 20 percent.
Using the GreenDP® control, the vessel is kept safe and secure within a predetermined operating range (range). Rather of reacting to the current conditions, this novel technique forecasts the vessel’s motion and uses a mechanism known as nonlinear model predictive control, which optimises the anticipated vessel offset vs the use of thrusters.
Small and short-term disturbances that do not drive the vessel out of its operating boundaries are therefore filtered out.This allows for very smooth control, dramatically lowering peak loads and significantly reducing the wear and tear on thrusters and is part of KONGSBERG’s Green Ship Strategy.
ABB Systems has been part of the development of marine system of incorporation which includes the positioning and better capabilities of operability.
ABB Ability™ Marine Pilot Control’s superior manoeuvring capability is built around predicting where the vessel will be in 5-30 seconds instead of measuring its position on arrival.
Software calculates the optimum way of executing decisions across the operational profile, depending on how the operator has prioritized speed, manoeuvrability, or other parameters.
Integrating DP2 capabilities into ABB Ability™ Marine Pilot Control underpins ABB’s commitment towards autonomous operations.
ABB Ability Marine Pilot Control’s DP optimizes energy efficiency against internal power plant status, thus adding value from the propeller up.
This benefits responsiveness, efficiency, and sustainability of vessel operations. As an example, accurate forecasts that a slight load peak will last a short time can avoid powering up another diesel generator.
Wärtsilä developed OPTI-DP Engagement Tool which takes all the calculations and data and allows multiple configurations to be modeled to ensure that the most efficient and safe thruster configuration can be achieved to deliver the thrust required for high performance dynamic positioning.
L3Harris developed the Minehunting Propulsion System, with two or three retractable azimuthal thrusters providing an unparalleled adjustability to the vessel in all MCM operations in order to facilitate identification of underwater targets, ROV and boats launch and recovery without exposing at risk the vessel itself.
The system is designed with the aim of providing an extremely low signature to vessel when sailing in minehunting mode.

This guarantees effective and safe operations, including vessel-to-vessel transfers, subsea construction, and offshore drilling.
The K-Pos DP22 system’s enhanced position reference system (PRS) is one of its most notable characteristics. To deliver precise and trustworthy location measurements, the PRS includes a number of sensors, including motion sensors, gyrocompasses, and differential global positioning system (DGPS) receivers.
In order to counteract external forces and maintain the intended position and heading, the system continuously analyzes these measurements and modifies the vessel’s thrusters and propulsion systems.
Advanced control algorithms are also incorporated into the K-Pos DP22 system to enhance the vessel’s efficiency. To ensure accurate and efficient dynamic placement, these algorithms take into account a number of variables, including environmental conditions, vessel features, and operating limitations. To improve system dependability and safety, the system also has redundant parts and fail-safe features.
The K-Pos DP22 system’s user-friendly interface and simple control scheme are another remarkable feature. Operators can easily monitor and manage the dynamic positioning operations thanks to the system’s clear graphical display of the vessel’s position, heading, and status.
Depending on the operational needs, the control system’s automatic, manual, and joystick control modes provide operators with flexibility and control alternatives. For owners and operators of vessels, the K-Pos DP22 system has a number of advantages.
By assuring exact placement and lowering the possibility of collisions with other vessels or offshore structures, it improves operational safety in the first place.
Additionally, it facilitates safe and effective operations in bad weather, enabling vessels to keep their position and stability even in choppy waters. The system’s fault-tolerant design and redundancy are further factors that increase operational security and dependability.
Second, the K-Pos DP22 system increases productivity and operational effectiveness. It lessens the effort on vessel operators and frees them up to concentrate on other important activities by automating position and heading control.
Because of the system’s improved control algorithms, fuel consumption is also kept to a minimum, lowering operating expenses and having a positive influence on the environment.
Additionally, performance optimization and post-mission analysis are made possible by the system’s sophisticated sensor integration and data logging capabilities.
The K-Pos DP22 system is used in a number of nautical industries. The drilling rigs, floating production units, and offshore support boats are just a few examples of where it is extensively employed in offshore oil and gas activities.
The device improves operational effectiveness and safety by enabling precise positioning during drilling, well intervention, and subsea construction activities.
Additionally, it is used in vessel-to-vessel operations where precise positioning is essential, such as crew transfers, supply delivery, and offshore maintenance.
