Abstract
The utility model discloses an all-electrically propelled supply ship for an offshore oil platform. The all-electrically propelled supply ship comprises an all-electric propelling system. The all-electric propelling system comprises two lateral propellers, a generator set, a main distribution board, two main propellers and a driving motor. The lateral propellers are mounted on a stem. The generator set is also arranged on the stem and is positioned in rear of the lateral propellers. The main distribution board is arranged in a distribution board room in rear of the generator set. The main propellers are mounted on two sides of a stern. The main propellers and the lateral propellers are connected with the driving motor respectively. Alternating currents generated by the generator set are converted into direct currents by the main distribution board, and the direct currents are converted into alternating currents which are supplied for the driving motor to drive the lateral propellers and the main propellers. The all-electric propelling system is adopted by the all-electrically propelled supply ship, so that arrangement of special equipment such as mechanical transmission shaft systems, shaft alleys and reduction gear boxes is not needed, and cabins for arrangement of the special equipment are omitted.
Description
Technical field
The utility model belongs to Marine engineering technical field, relates in particular to a kind of full electric propulsion offshore platform supply boat.
Background technology
Traditional offshore platform is supported ship, in order to meet the needs of ship's fix function, is conventionally furnished with gear case and the power that the primary mover that is installed on machinery space sent by long axis system is that watertight division compression gland and anti-explosion packing gland pass to angle of rake stern tube shaft and be by bearings, transmission shaft, axle.Due to daily attention and inspection, maintenance needs, this axle system needs to arrange the enough large operational spaces that meet that IMOJi the ILO, classification society require, so has taken larger boats and ships space.Therefore and because its screw propeller of this transmission of power can not provide the moment of turning ship of 360 degree to maintain the positioning action of boats and ships, in order to meet the requirement of DP-II dynamic positioning, ship stern at least configures two side thrusters and two steering wheels, two rudder gears.Side thruster and steering wheel all need to arrange special cabin, and these equipment all requirement can control at operator's compartment, therefore not only take larger space, on controlling, also make control system huger, when carrying out ship's fix, its control program is very complicated, and equipment is various.When ship's navigation and location, the equipment of operation is various, and the equipment that operating personal need to be guarded is many, and safeguards complicated and difficult.
Utility model content
Utility model object: the utility model provides a kind of full electric propulsion offshore platform supply boat of simple in structure, easy care.
Technical scheme: full electric propulsion offshore platform supply boat described in the utility model, comprise full electric propulsion system, described full electric propulsion system comprises side thruster, generator set, main switchboard, main thruster and drive motor; Side thruster is arranged on ship bow part; Generator set is arranged on ship bow part equally, is positioned at the rear side of side thruster; Main switchboard is arranged in the electric panel room of generator set rear side; Main thruster is arranged on ship stern both sides; Main thruster is connected respectively drive motor with side thruster; Generator set is connected with main switchboard, and main switchboard connects drive motor; The alternating current that generator set sends transfers direct current (DC) to by main switchboard, then transfers alternating current supply drive motor to by direct current (DC), drives side thruster and main thruster.Drive motor adopts variable frequency control, and frequency-variable controller is arranged on main switchboard.Generator set is comprised of four electrical generators; Generator speed regulates within the scope of 900rpm～1800rpm according to boats and ships electricity consumption load.
Beneficial effect: the utility model, owing to adopting full electric propulsion system, does not need the equipment such as special-purpose mechanical drive shaft system, shaft tunnel, reducing gearbox are set, has saved the cabin of arranging Special Equipment.Adopt the marine shafting length of traditional propulsion system often to account for captain's 40% left and right, the PSV of 85 meters of left and right adopts after driven by power, only reduces shaft system arrangement and just can save the space of approximately 150 cubes, the corresponding displacement in this space, for the loading of goods, improve and load and traffic capacity.Generator frequency of the present utility model is automatically always moved power size with boats and ships and is automatically adjusted, thereby more effectively improve electrical generator work efficiency, guarantee that the primary mover of electrical generator works in the best region of equipment operation all the time, reduce oil consumption and noise, improve boats and ships operating efficiency and energy saving.Full electric propulsion system adopts the main row-Alternating Current Power Supply of alternating current generator-direct current technology, can significantly reduce oxides of nitrogen total amount and greenhouse gas emission, and greenhouse gas emission can reduce up to 20%.
