Container Tanks

A container tank is a transport facility intended for safe domestic and international transportation of goods by road, by rail and by sea (river) and storage at a consignee of liquid safe and hazardous cargoes. The container tank complies with the provisions of the International Convention on Safe Containers and with those of the Customs Convention on Containers.

The stock of container tanks possessed by OVZ-Trans JLLC is generated of the cargoes manufactured by Osipovichi Carriage Works JV CJSC under the design documentation for models Т11 and Т14 developed by Metalcomposit Research and Development Center LLC (the Russian Federation) and "SURETANK LTD" (Ireland) - for type T50.

The certification body is the Russian Maritime Register of Shipping FAI.

In respect to their weight and dimensions the container tanks are complying with the requirements of Standard ISO 668:1995, have dimension 1CC; they are designed and tested to resist load as per the requirements of Standards ISO 1496-3:1995 and GOST 31314.3-2006. According to the classification of transported containers adopted by UN the container tanks are qualified as the containers meeting the requirements of UNT instructions

The containers have a solid structure procuring their multiple utilization; they are equipped with elbow fittings used for loading, unloading, decking and fastening. A container tank is composed of a tank equipped with loading/unloading valves for effecting loading/unloading operations under pressure and by force of gravity, a frame (bents) equipped with elbow fittings used for loading, unloading, decking and fastening of a container. A tank is a welded vessel composed of a cylindrical sidewall and two elliptic or torispherical bottoms. The tank elements are interconnected by end joints with full weld penetration by means of electric welding.

The tank is secured to the end frame by means of hip jacks and sidewalls. For procuring container toughness under external excessive pressure structural rings are welded to its external surface (in models Т11 and Т14). The tank is equipped with a manhole hatch of 500 mm diameter (in the clear) located in the top part of a cylindrical sidewall (in models Т11 and Т14) or from the side of the end frame (in Т50 models).

The end frames (the front and back ones) are welded assemblies composed of vertical diaphragm, top and lower cross arms, a supporting ring, reinforcing plates, detents of tank hip jacks and bed plates.

The frame elements are manufactured of low-alloyed steel: 09Г2С strength index 45 GOST 19281-89, P355NL1, P355NL2 EN 10028, S355MLH EN 10219-1 or S355J2H according to EN 10210.

The frame legs are connected with jigs by means of top and lower elbow fittings intended for loading/unloading operations with a container, for fastening a container onto carrier vehicles and for interconnecting containers when decking thereof. The form and dimensions of elbow fittings are complying with Standards ISO1161:1984 and GOST Р 51891-2002.

A container is lifted by the top elbow fittings by suspensions made in the form of a yoke equipped with tilting locking devices, or suspensions with slings with hooks connected thereto, or by lower elbow fittings equipped with rigging slings with hooks.
