Towage & Passage
One of the core activities of our company is the Organization of Sea Towing, as well as the development of a Single Voyage Plan.
We specialize in the development, organization and coordination of all the required measures - both with the Classification Societies that supervise ships, and the Maritime Administrations, as well as the Port Authorities, for the following types of towing:
- - planned towing of a vessel - for example, the hull of a new vessel to the place of installation of the engine and equipment, a floating crane or a sailing vessel with a retracted boom or mast along inland waterways (rivers and canals with passage under bridges), moving a vessel from one water basin to another, outside the established navigation area.
- - towing of a damaged vessel (floating object) that has lost its speed or is deprived of the ability to navigate.
The standard scope of services for the development of a Marine Towage Design Project usually includes:
- 1. Explanatory note indicating the characteristics and requirements for the technical state of the towed object, analysis of the requirements of regulatory documents applicable to this case, a description of the area and conditions of towage operation, measures to ensure the safety of towing (including measures of the environmental protection);
- 2. Selection of the optimal route, taking into account the distances from shelter sites, ports of refuge and GMDSS areas, as well as restrictions on permissible wind-wave characteristics during the towage operation;
- 3. Description of the navigational situation and weather conditions along the towing route;
- 4. Calculation of the safe speed and the required bollard pull for towing the vessel, as well as the calculation of the elements of the towing line;
- 5. Selection of a tug with optimal performance characteristics for towing purposes, in relation to the towing object;
- 6. Calculation of the forces acting on the towed object, taking into account the predicted weather conditions;
- 7. Calculations of strength, stability and freeboard for the towage area and conditions;
- 8. Drawings of the reinforcement of the hull and superstructures;
- 9. Drawings and diagrams of closing openings in the hull and superstructures of the vessel (converting), as well as installation of structures to increase seaworthiness (breakers, protection of superstructures, deckhouses);
- 10. Scheme of the towing line, towage plan, fencing protection scheme;
- 11. Drawings of the location of navigation lights and daytime signals of the towed vessel;
- 12. Description of the power plant, electrical, radio and navigation equipment of towing vessels;
- 13. Description of the steering, anchor, mooring devices, fire protection and equipment, rescue and signaling means on all ships of the tugboat;
- 14. List of emergency supplies and a diagram of its placement on all ships of the tugboat;
- 15. Instructions for the tug Master, including organizational measures, established weather restrictions, instructions on the safe speed and length of the tug, use of ship's stores, damage control of a vessel in emergency situations.
- 16. Approval of the Marine Towage Design Project in the Classification Society;
- 17. Approval of the Marine Towage Design Project in the Maritime Administration with the subsequent receipt of a Single-Voyage Towage Permission Certificate (if required).
A competently done Marine Towage Design Project will ensure the safe delivery of the towed object from the port of departure to the port of destination, in which the towing vessels:
- ● have information on permissible waves, wind forces, distances between ports of refuge; where the management of the risk of getting into unfavorable weather conditions - exceeding their capabilities - lies solely with the tug Master;
- ●will not tear the tug, will not be pulled out of the deck and will not damage in any other way its anchorage points;
- ● will not run the towed vessel aground or roll it over an obstacle;
- ● will not be left without fuel, fresh water or food;
- ● will be able to receive weather forecasts and navigation warnings;
- ● will be able to contact the shore at any time to request information or assistance;
- ● in case of worsening weather or an emergency situation on board, they will be able to safely reach the port of refuge.
Aug. 2020 - Heavy lift oversized cargo transportation calculations and towage plan developed by our Company.
We are also ready to offer additional services to provide a turnkey complex through our partners, namely:
- ● provision of suitable tugs for towing purposes;
- ● organization of technical survey;
- ● preparation of the floating craft for towing (converting);
- ● presentation of the craft to the inspector of the Classification Society;
- ● towage insurance.
