DEVELOPMENT AND DEMONSTRATION OF A UNIFIED TECHNOLOGY FOR THE TRANSFER OF PARTICULARLY HEAVY, LARGE-SIZE FLOATING AND HYDROTECHNICAL (OFFSHORE) STRUCTURES BETWEEN LAND AND FLOATING DOCKING OR TRANSPORT UNITS, USING AUTOMATED COMPUTATIONAL ALGORITHMS

Financing agreement no.: POIR.01.01.01-00-1169/19-00 of 28.05.2020

Project summary

As part of the project implemented by the consortium of Alkor Sp. z o.o. and Safe Co. LTD. Sp. z o.o., a unified technology for transferring particularly heavy, large-size floating and hydrotechnical (offshore) structures between land and a floating docking platform will be developed and demonstrated, using automated computational algorithms.

The project will be implemented in three stages as development works. The first stage will cover design works, while the remaining two stages will focus on experimental development works. The project will be carried out by Consortium members with complementary competencies and extensive experience in the shipbuilding industry. The R&D team also includes scientists from Gdańsk University of Technology and a subcontractor with an experienced scientific and technical staff. As a result of the project, the Consortium members will introduce to the market an innovative service for transferring large-size structures from land to water and from water to land. The project implementation will also contribute to strengthening the competitive position of the Consortium members and to the development of the Polish shipbuilding sector.

The development works will concern

  1. Conducting analyses, including numerical analyses and simulations, in order to develop a docking concept using SPMT platforms on the floating docking platform (hereinafter referred to as FDP), taking into account the transport of docked structures.
  2. Preparation of design documentation for the FDP prototype, the transport bridge prototype, and development of software utilizing automated computational algorithms.
  3. Creation and real-life testing of prototypes – the floating docking platform and the transport bridge.

The results of the project will include, among others:

  1. An innovative floating docking platform enabling the transport of large-size structures from land to water and from water to land.
  2. Increased safety of cargo transfer processes on land through the use of solutions ensuring high maneuverability on uneven terrain.
  3. Enabling the transport of heavy structures from land to water and from water to land at quays with low permissible load capacity.
  4. Reduction of the time required for vessel docking/undocking operations.
  5. Implementation in the Consortium companies of automated computational algorithms using software for planning, cost estimation, control, and safety monitoring of the structure transfer process.

Project implementation period: 01.06.2020 – 31.12.2022

The total cost of the Project amounts to: PLN 23,961,538.75

Contribution from European Funds: PLN 9,584,615.50

The project is co-financed by the European Union from the European Regional Development Fund under the Smart Growth Programme. The project is implemented under the National Centre for Research and Development competition: Fast Track no. 6/1.1.1/2019.

FDP IN HYDROTECHNICAL CONSTRUCTION

Advantages of introducing the FDP platform into hydrotechnical construction*

The implementation of hydrotechnical structures, regardless of their type (revetment, erected, or mixed structures), depends on weather conditions at sea. Construction in open sea conditions is very time-consuming and exposed to storm-related weather interruptions (it is necessary to assume even a 25–35% time reserve for downtime). Often, already completed elements must be secured against storms, which also increases execution costs.

The use of the FDP platform in the construction of hydrotechnical structures carried out at sea provides the possibility of partially reducing dependence on weather conditions by producing large reinforced concrete floating structures (e.g. caisson foundations) in fully sheltered conditions inside ports. As a result, the construction time is significantly reduced, and the execution cost is at least 10% lower.

The FDP platform would be used only for the construction of the lower parts of the structures, which, after achieving buoyancy, would be docked and moved out of the FDP. The concreting of the designed structures to their final dimensions would then be carried out at the quay.

FDP IN THE PROCESS OF TRANSFERRING PARTICULARLY HEAVY, LARGE-SIZE FLOATING STRUCTURES

The Floating Docking Platform is a project introducing an innovative service to the market for transferring large-size floating and hydrotechnical (offshore) structures from land to water and from water to land, using automated computational algorithms.

The transport process will be carried out on modular SPMT (Self-Propelled Modular Transporter) platforms. A self-propelled modular transporter is a special vehicle equipped with hydraulically controlled steering and hydraulically controlled lifting.

Thanks to the high lifting capacity of the FDP (3,000–5,000 tons), the transported structures can be fully outfitted, e.g. ships or other fully equipped large-size structural and technological modules.

Naciski/obciążenie jednostkowe na polskich nabrzeżach portowych wynoszą 2,0 t/m2, dlatego zaprojektowana została specjalna kładka/pomost, która będzie służyć do transportu wielkogabarytowych konstrukcji o masie 3000 ton nad częścią nabrzeża

The total time for transport from the quay to the FDP and launching will be 5 hours for a vessel weighing 1,200 tons – compared to up to 48 hours with current methods.

The length of an object that can be side-loaded onto the FDP after dismantling the towers is at least 90 m.
