At the II Inter-industry Conference "Underwater Technical Works: Innovations, Technologies, Safety", held in St. Petersburg, specialists from the United Shipbuilding Corporation (USC) demonstrated the concept of a new vessel for underwater technical tasks. It is designed to localize the impact of potentially dangerous objects at significant depths.
The project envisages the creation of a vessel for providing underwater technical works. It will be able to operate at depths of over 1000 meters. The crew will be able to perform a full cycle of operations: transport cargo, raise sunken objects and install engineering protective barriers over them. For these tasks, a crane with a lifting capacity of 100 tons will be placed on the deck. The mechanism will be equipped with a deep-sea winch and a vertical roll compensation system. The cargo area of the ship will accommodate both technological equipment and the raised objects themselves or shelters for them.
Engineers of the corporation also proposed a separate technical solution for the installation of large protective barrier containers. A method has been developed for transporting and precisely installing shelters weighing more than 1000 tons at depths of up to 300 meters. Cable guides are used for this.
The advantage of this approach is that it is not necessary to build a new expensive fleet for such an operation. The installation can be carried out using existing vessels, which significantly reduces the cost of work. Precise positioning allows reducing the size of the barriers themselves, and therefore, reducing the cost of their production.
