Transport pontoon Sevan. Project 426МВ

Ship class

KE ⍟ R3-RSN Pontoon for transportation services of Russian Maritime Register of Shipping

Purpose

Multipurpose transport facility intended to carry heavy and bulky metal structures for offshore construction in the Caspian Sea as well as to carry cargo in the river Volga.

Distinctive features

The main operational task of the pontoon is to transport the drilling rig LSP-1 built at the site of Astrakhan Shipbuilding Production Association (ASPO) through the Volga-Caspian channel to the place of operation in the North Caspian (oil field n.a. Ju. Korchagin).

Area of navigation – the river Volga and the Caspian Sea to the North of parallel 44°30' at the wave height of up to 2.0 m with 3% probability of exceedance (March-November). The transport pontoon has its own power plant to provide the operation of the high-powered ballast system and to serve the ship's needs. Ballasting of the transport pontoon is performed by one operator from the control panel. Sevan was reequipped from the fuel oil barge of project 426М by increasing its cargo capacity due to refitting the pontoon with the side bulges and increasing of the ship breadth.
