Embodiment Construction

[0014] exist figure 1 In , the solution according to the invention is exemplified by a single circuit to one remote end of the vessel. The figure shows two main redundant groups 1a, 1b each shown with a generator 7 coupled to two main switchboards 4a, 4b and optionally thrusters 6 and switches A device 5 for feeding auxiliary devices in the corresponding redundant group, wherein the main switchboards 4a, 4b are connected to each other by means of busbars 8 .

[0015] The main switchboard 4a of each main redundant group is connected by cables to the thruster redundant group 2a respectively, and connected by transformers and AC / DC converters to the interconnected autonomous thruster drives comprising thrusters 6 and auxiliary units 5 3. The thruster drive 3 may also comprise a DC / DC converter type circuit breaker for controlling and / or protecting the DC link 9 to a redundant set of adjacent thrusters. In this way, redundant sets of thrusters are connected by DC interconnects,...

Abstract

The present invention relates to a power supply system, especially for a floating vessel, comprising at least two segregated power sections, each constituting a main redundancy group, and each comprising at least one of a power generator adapted to generate an electrical power to a main switch board and a power consumer, such as a propulsion unit, drawing power from said switch board, and a bus-tie connecting the main switch boards of each redundancy group. The system also comprises at least to segregated directly powered thruster redundancy groups, each including a thruster drive, each beingconnected to the main switch board of a corresponding one of the main redundancy groups, respectively, the thruster redundancy groups including AC / DC converter means and a DC interconnection connecting the thruster redundancy groups thus proving a loop structure, the thruster redundancy groups being able to draw power from both main switchboards.

Description

technical field [0001] The present invention relates to an electrical system and thruster drive design aimed at increasing the capacity and fault tolerance of seagoing vessels at reduced cost, space and weight. Background technique [0002] A large number of ships at sea is required to have redundancy in the design of the power and propulsion of the ships. This is to ensure that after the worst of a failure, the vessel is still designed to withstand, still having sufficient power and full propulsion capability. Power and propulsion thrust requirements after a failure will depend on the type and use of the vessel. Therefore, the vessel may maintain a minimum propulsion speed / thrust or propulsion capability to maintain a fixed position. [0003] Ships that require design redundancy, such as dynamically positioned ships, typically have their power and propulsion units divided into two or more redundant groups. Each redundant group typically has one or more engines and one or...
