Multi Modular Safety Device to service the Port Industry

Dynamic Protective Barrier (DPB) is an innovative safety device with a novel mechanism proposed to dissipate energy for short duration impact caused by the docking ship and/or vessels.

The main job of the device is to dampen and contain the vessel movements, thus eliminating the effect that passing ships, tides, wind and long-period waves have on moored vessels and the constant low velocity impact that occurs with the port infrastructure. This means using Dynamic Protective Barrier can eliminate the structural damage that occurs and can assist in improving safety and reducing operational costs of ports and marinas.

Additionally, the developer of Dynamic Protective Barrier claims the technology has advantages over conventional bollards such as reduced time for securing vessels and associated reduction in labor costs. This further increases the range of environmental conditions in which cargo can be transferred. It further enhances safety by keeping the vessels stagnant thus, simplifying day-to-day operations. The system speeds up the berthing process and minimizes workload and manual line handling thus improving overall efficiency.

Present methods on the market such as rubber fenders are limited solutions that accumulate the kinetic energy resulting from the low impact of the mooring/docking vessels hence causing cracks in the quay walls, sometimes even damaging the vessels which have an economic impact. DPB aims to eradicate the constant repair of quay walls and vessels. It also aims to reduce time for securing vessels alongside and associated reduction in labor costs which is usually spent in the regular replacement of the fenders by effectively dampening the impact and thus dispersing the load using this innovative technology.

DPB – The Innovation

Dynamic Protective Barrier is a device that actively disperses the energy gained from the action of one object coming forcibly into contact with another, thereby converting the translational kinetic energy to rotational kinetic energy.

DPB’s self- return system (SRS) works constantly in conjunction with the vessel which can also be used as a kinetic energy recovery system to power electricity through a DC generator. In addition, DPB can be utilized and function as a constant tidal/wave renewable source of energy and be self-sustainable. As the Ports & Marina industry shifts to zero emissions carbon neutral and electrifying their fleet, DPB and its technology is well positioned to support this movement.

Physics & Working

  • Converts input translational Kinetic Energy to Rotational Kinetic Energy
  • Dissipates energy for a short duration load
  • The incident translational energy instead of getting absorbed as plastic strain energy is converted to rotational kinetic energy
  • Disbursement process occurs through the interchangeable rotational masses which can cater to vessels of different size & load
  • DPB is designed to engage and retract (self return system).

Why DPB is the solution?

Fenders just partly absorb the impact of vessels while dockingDPB disperses the impact load effectively
Leads to walls getting damaged hence increasing the cost of repairing the infrastructure The quay walls remain protected as the impact is safely contained and disbursed  
Increases the lead time as business is lost due to constant repairing of the quay walls No repairing required hence business continues to thrive   
Loading and unloading of cargo takes time because fenders push back some of the impact caused by the vessels (Newton’s Third Law)Loading and unloading of cargo is much safer and easier as the device dissipates the energy without any opposing force  

DPB and its innovative technology offer the following benefits;

  • Reduces the overload/forces at the time of impact
  • Protects the infrastructure from micro and macro damages
  • Minimizes the structural damages to the vessel while docking
  • Improves safety by containment of the vessel
  • Cost effectiveness due to its innovative design
  • Low maintenance and self-sustainable
  • Adaptability and versatility to different infrastructures

Maintenance, Service and Installation

  • Environmental materials are considered in the production state of DPB such as composite materials therefore low maintenance required.
  • Installation is based on anchoring and securing DPB onto the existing port/marine infrastructure such as docks and quay walls.
  • Lubrication and inspection of components required annually or as needed


  • There are limitations to the current ports industries docking infrastructure system
  • DPB is an innovative safety device that dissipates energy for short duration shock load
  • Converts input translational Kinetic energy to Rotational Kinetic energy
  • Protects the wharf structure and quay walls
  • Provides a wide spectrum of applications once implemented such as ease of cargo transfer and berthing process
  • DPB is geared towards infrastructures such as marinas, harbours, ports, and/ or vulnerable structures ie: offshore energy platforms.
  • DPB can cater to vessels of different sizes & weight
  • Future scope – self-sustainable renewable source of energy

Mauritania ports

Mauritania is located at strategic crossroads in the north Africans, and at the heart of many Atlantic shipping lanes . the country its distinguished position with its Atlantic coast, which includes more than 750 km . In addition to its proximity to Europe. As well as the direct access to important reginal markets, such as Algeria, Mali, Morocco and Senegal.

This is what prompted the Mauritanian government to benefit from this geographical location and to develop the port sector.

Work has been done to expand the most important port in the country, which is the port of friendship, also known as the Autonomous port of Nouakchott, and port of Nouadhibou, which is considered an economic lever, is Mauritania’s gateway to export, especially iron ore, in addition to the construction of two new ports in the past five years, which are “Tanit Port” and “Ndiago Port“.

Offshore Gas projects

In July 2021, the GTA project is granted Status of National Project of Strategic Importance by the Presidents of Mauritania and Senegal. The agreement was made with two companies, British Petroleum (OPERATOR), and KOSMOS ENERGY
This important recognition shows the commitment of the host governments and the importance of the project to both countries.

2023 year waiting for Mauritania to enter the club of liquefied gas producing countries, after the promising discoveries, which brought giants of oil and gas production, as the country will witness the export of the first shipment of extracted gas, from fields located in The Mauritanian-Senegalese territorial waters, with the start of production from the “Tortue-Ahmeyim” field, which was scheduled to start production in 2022, but it was not spared from the repercussions of the Covid-19 pandemic, which delayed the process of starting production in the field.
And estimates indicate that the reserves of this field it reaches more than 450 billion cubic meters.

The large natural gas reserves that were discovered off the coasts of Mauritania, increased the activity of Mauritania’s ports (the port of Nouakchott, the port of Nouadhibou, the port of Ndiago).

  • Logistical support, and supply chains in the process of building an offshore gas extraction plant
  • Preparing the infrastructure to receive the extracted gas

With the expected increase of activities in the ports of Mauritania, the DPB will have an important role in protecting the infrastructure of ports and ships, as well as increasing the efficiency of loading and unloading operations.

1- Autonomous Port of Nouakchott Port of Friendship

The port of friendship in Nouakchott, known as PANPA, has a privileged geographical position. At the crossroads of Africa, Europe and America, this is one of the first public commercial ports in sub-Saharan Africa for ships departing from Europe.
The performance of the port of Nouakchott in terms of handling rates generally ranges from 1200 tons to 2500 tons per day for the packing plant, 3 containers per hour. 95% of the traffic in the port of friendship is imports products. The total potential movement capacity is one million tons

Since it represents one of the pillars of the national economy, its traffic has grown exponentially since its commissioning in 1986, rising from less than 400,000 tonnes in 1987 to 3,675,814 in 2016, at an average rate of + 9.52% per year.

Containerized traffic has increased from 56,448 TEUs (twenty-foot equivalent containers) in 1988 to ~134,413 TEUs in 2016, an average increase of +12.5% per year.

Mauritanian President Mohamed Ould Cheikh El Ghazouani inaugurated, on 14.12.2021, a new expansion of the port of Nouakchott, which was completed at a cost of 320 million dollars.

According to the Mauritanian News Agency, this expansion consisted of building a container berth with a length of 570 meters and a depth of 15 meters.

The agency indicated that this expansion provided the port with an additional capacity of 600,000 containers annually, in addition to the port’s previous capacity of 350,000 containers.

According to the same source, this expansion also enables the port of Nouakchott to receive ships of large size, and to triple its unloading capacity.

Transport Minister Mohamedou Ould Ahmedou Ould Mhaimid said that this expansion includes two berth bridges and modern handling equipment that will improve the pace of handling in the port and provide 500 direct job opportunities.

In a speech during the inauguration ceremony, the minister indicated that a significant increase in fees had been made that would enable the state’s public treasury to increase its revenues from the utilization of the berth, by nearly $157 million.
