Abstract
A sea vessel (1), such as a tugboat or a fishing vessel, including a hydraulic winch (10) connected to a hydraulic system (100), and at least one main engine with a main engine crankshaft (22) connected to a propeller or a thruster. The hydraulic system (100) comprising: a first, hydraulically powered genset (106) including a hydraulic motor and a generator, at least one hydraulic pump (105) connected to said crankshaft (22). The hydraulic pump (105) is configured for driving said first genset (106) to generate electricity, and the hydraulic pump (105) is configured for driving said hydraulic winch (10), and first valve element (102) are used for selectively directing hydraulic fluid to the hydraulic winch (10) or to said first genset (106) of said hydraulic system.
Claims10
A sea vessel comprising:
- a hydraulic winch connected to a hydraulic system, and
- at least one main engine with a main engine crankshaft connected to a propeller or a thruster, said hydraulic system comprising:
- a first, hydraulically powered genset including a hydraulic motor and a generator;
- at least one hydraulic pump connected to said crankshaft,
- said hydraulic pump being configured for driving said first genset to generate electricity;
- and
- said hydraulic pump being configured for driving said hydraulic winch;
- and
- a first valve element for selectively directing hydraulic fluid to said hydraulic winch or to said first genset of said hydraulic system.
A sea vessel hydraulic system connectable to a hydraulic winch of a sea vessel, where the sea vessel comprises at least one main engine with a main engine crankshaft connected to a propeller or a thruster, said hydraulic system comprising:
- a first, hydraulically powered genset for generating electricity and connectable to an electrical power distributor of the sea vessel;
- said first genset including a hydraulic motor and a generator,
- at least one hydraulic pump connectable to said crankshaft;
- a hydraulic fluid piping connecting said hydraulic pump with said first genset;
- said hydraulic pump being connectable to said hydraulic winch for driving the hydraulic winch;
- and
- one or more first valve element(s) for selectively directing hydraulic fluid from said hydraulic pump to said hydraulic winch for said driving of the winch or to said first genset of said hydraulic system.
