Abstract

FIELD: shipbuilding; building of offshore oil-loading terminals. SUBSTANCE: proposed offshore submersible oil-loading terminal includes interconnected floating members made in form of pontoons-tanks provided with heating sources for heating oil stored in them; they form in plan chamber bounded with two longitudinal walls, transversal wall and hydraulic gate valve which is opposite to transversal wall. Terminal may be delivered to required region in assembled state. EFFECT: enhanced operational reliability in shallow waters of arctic seas. 1 dwg

Description

The invention relates to shipbuilding, in particular to the construction of submersible berths for receiving and loading ships, such as tankers, with oil in the conditions of the coast (shallow) of the Arctic Sea.

Known collapsible floating pier for the needs of the fleet of rectangular shape in plan, including floating elements (pontoons) in the form of a parallelepiped, interconnected by attachment points in the upper and lower parts of the floating elements (AS USSR 659450).

The disadvantage of this technical solution is that the location (configuration) of its floating elements (pontoons) does not protect ships from wind, waves and broken ice in the conditions of the coastal (shallow) of the Arctic Sea.

Known marine submersible oil berth ice class contains floating elements, including tanks for storing oil and forming a chamber enclosed by two longitudinal walls and one transverse wall.

The specified invention has a low operational reliability of the berth in shallow waters of the Arctic Sea.

The basis of the invention is to increase the operational reliability of a submersible pier in the coastal (shallow) Arctic Sea.

The problem is solved in that an ice-class marine submersible oil berth of interconnected floating elements is proposed, in which, according to the invention, the floating elements are made in the form of pontoons tanks with the possibility of heating the oil stored in them and form a chamber enclosed by two longitudinal walls transverse to the race and the last opposite hydraulic shutter, and the berth is made with the possibility of delivering it assembled to a given area and installation on the coastal seabed or ydvizhnye support.

The water space in the chamber (berth) is maintained in an ice-free state due to the heating of the oil stored in the tanks.

The proposed marine submersible oil-loading berth of the ice class can operate autonomously at any point on the coast of the Arctic Sea, has its own power plant for generating electricity, steam, compressed air, etc .; fuel reserves of lubricants and fresh water sufficient for the operation of the oil berth and personnel for a specified period of time; living quarters for staff (canteen, medical unit, bathhouse, etc.). stipulating the possibility of functioning of the berth outside the village; repair shops; means of protection from the effects of ice, as well as a system for pumping fuel from the coast to the pier and from the latter to the tanker.

The entire design of the ice class submersible berth in the ice class assembled at the plant can be delivered to a given point, put on the coastal seabed or on special retractable supports.

The drawing shows an ice-class marine submersible oil berth containing a rectangular chamber 1, fenced with longitudinal walls 2, a transverse enclosing wall 3 and a hydraulic shutter 4, floating elements (pontoons, nuts) 5, a helipad 6 and a tanker 7. Power plants are not presented, berthing facilities, residential and auxiliary facilities, workshops, crane equipment, etc., as well as systems for pumping liquid fuel to intermediate berth capacities and from them to an oil tanker.

Ice submersible berth ice class works as follows.

The hydraulic shutter 4 is opened, the tanker 7 is introduced into the rectangular chamber 1 and moored to the berth, the hydraulic shutter 4 is closed, the tanker 7 is loaded with oil, the hydraulic shutter 4 is opened, the tanker is taken out of the chamber and the hydraulic shutter 4 is closed.

Sea pier is ready to receive the next tanker.
