Launch device of lifeboat for personnel at offshore oil and gas facilities in ice conditions


B63B23/32 - Rigid guides, e.g. having arms pivoted near waterline

FIELD: ship building.

SUBSTANCE: invention relates to ship building, particularly, relates to evacuation and rescue of personnel of offshore oil and gas facilities that are located in the Arctic and far eastern freezing seas. Launching device of lifeboat for personnel at offshore oil and gas facilities in ice conditions comprises launch platform with guide rollers and shelter lifeboat deck. Fender bar of Lifeboat with a locking device is placed against the guide rollers. Root sections of two telescope-type holders are affixed to the shelter lifeboat deck, and their end sections are affixed to the launch platform. Holders are made with the possibility of adjusting their installation angle in relation to the horizon, and lifeboat and shelter lifeboat deck are equipped with the winches which are interconnected by a cable.

EFFECT: higher safety of personnel evacuation from off-shore facilities.

SUBSTANCE: invention relates to ship building. Proposed power generator comprises main engine connected with main generator and local control system. Main generator is connected with propulsion motor via electric circuit including first circuit breaker, main buses, consuming hardware buses, frequency inverter and extra motor/ Extra motor is connected with additional generator connected via second automatic circuit breaker to busses of consuming hardware. Main and extra generators are three-phase electromagnetic excitation generators equipped with first and second phase current output transducers. Local control system can be connected to top level control system, first and second current phase and voltage transducer mounted at consuming equipment buses. Controlled frequency inverter comprises rectifier and inverter connected in series equipped with intrinsic controller. Current sensors connected with controller data input are built in rectifier power output power circuit and inverter input power circuit. Choke is connected to controlled rectifier power input. Choke other output is connected to phase voltage sensor and to third automatic circuit breaker connected to main buses. Phase voltage sensor is connected with rectifier controller. DC link capacitor accumulator and dc voltage sensor connected to both controllers are built in between rectifier output power circuit and inverter input power circuit current sensor. Controllers are connected to selector of operating conditions connected with local control system.

EFFECT: higher efficiency of bus power supply.
