- FIG. 1 shows a sectional, cut view of a vessel 100 according to one embodiment.
- the vessel 100 has a roll stabilization arrangement with a first tank 1 10 and a second tank 1 1 1 , which are configured to hold a water column.
- a channel 1 12 connects a lower part 1 10a of the first tank 1 10 to a lower part 1 1 1 a of the second tank 1 1 1 .
- Such a roll stabilisation arrangement will be familiar to those skilled in the art; as the vessel 100 rolls, the fluid (typically water) in the tanks 1 10,1 1 1 and the channel 1 12 will move cyclically between the tanks 1 10, 1 1 1 with substantially the same frequency as the roll motion.
- the tanks 1 10,1 1 1 are designed such that the movement of the water is out of phase with the roll motion, and such that the tanks produce a righting moment on the ship.
- the tanks 1 10, 1 1 1 and the channel 1 12 may be placed above or below the ship's metacentre (roll centre) 101 .
- a passive roll stabilisation arrangement can reduce roll by typically 40-60%.
- a liquid turbine unit 1 13 is arranged in the channel 1 12.
- the liquid turbine unit 1 13 may be any type of rotodynamic machinery, for example can the liquid turbine unit 1 13 comprise a water turbine, a propeller, or the like. Some embodiments of turbine units 1 13 will be described below.
- Figure 2 shows an alternative embodiment, where the vessel 100 has a second channel 122 arranged to connect an upper part 1 10b of the first tank 1 10 to an upper part 1 1 1 b of the second tank 1 1 1 .
- a gas turbine unit 123 is arranged in the second channel 122. In this embodiment, no liquid turbine unit is arranged in the channel 1 12.
- the tanks 110, 1 1 1 and the channels 1 12, 122 form a closed volume, such that a liquid movement from e.g. the first tank 1 10 to the second tank 1 1 1 will force an equivalent volume of gas (generally air) through the second channel 122 and through the gas turbine unit 123.
- the gas turbine unit 123 may be of various different designs and many types of rotodynamic machinery may be suitable for this purpose.
- Fig. 3 shows yet another embodiment according to the present invention.
- a gas turbine unit 133 is arranged in the upper part 1 10b of the first tank 1 10 and another gas turbine unit 134 arranged in the upper part 1 1 1 b of the second tank 1 1 1 .
- the tanks 1 10, 1 1 1 are open to the atmosphere by vent ducts 135 and 136, respectively.
- a liquid turbine unit 1 13 is arranged in the channel 1 12, in addition to the turbine units 133, 134. This is optional, however may be advantageous in that the operation of the individual turbines may be controlled in the most efficient or optimal manner.
- Fig. 3 shows yet another embodiment according to the present invention.
- a gas turbine unit 133 is arranged in the upper part 1 10b of the first tank 1 10 and another gas turbine unit 134 arranged in the upper part 1 1 1 1 b of the second tank 1 1 1 .
- the tanks 1 10, 1 1 1 1 are open to the atmosphere by vent ducts 135 and 136, respectively.
- FIG. 4 shows another embodiment, wherein a liquid turbine unit 1 13 is arranged in the channel 1 12 and gas turbine units 123 are arranged in the second channel 122.
- Fig. 5 illustrates one possible embodiment of a turbine unit 1 13, 123, 133, 134.
- the turbine unit 1 13, 123, 133, 134 comprises a propeller 1 14 coupled to an electric generator 1 15.
- Any type of fluid turbine 1 14 may be used, and this unit may be chosen based on the fluid (gas or liquid) and projected flow rates through the turbine unit, using conventional design methods.
- the generator 1 15 may be electric, as in this embodiment, but may also be of a different type, such as a hydraulic generator.
- One or more of the turbine units 1 13, 123, 133,134 may further comprise a control unit 125 which is configured for regulating the torque acting from the generator 1 15 on the turbine 1 14. In this manner, the flow resistance through the turbine unit 1 13, 123, 133, 134 can be regulated, and thereby the electrical power generated as well as the damping effect of the roll stabilization
- the turbine unit 1 13,123, 133, 134 may further comprise a guide vane 126a, 126b arranged to guide a fluid towards the fluid turbine 1 14. This may be arranged so as to give a narrower or smaller flow path for the fluid past the turbine 1 14, and thereby improved performance in terms of, for example, power generated or controllability of the flow resistance.
- the vessel 100 may have a power distribution network 151 , illustrated in Fig. 6, where at least one turbine unit 1 13, 123, 133,134 is operatively coupled to the power distribution network 151 such as to allow power generated by the turbine unit 1 13, 123, 133, 134 to be supplied to the power distribution network 151 .
- the vessel 100 may, for example, have engine generators 152,153, such as diesel engines, operatively coupled to the power distribution network 151 in the usual manner.
- the vessel 100 may have one or more battery units operatively coupled to the power distribution network 151 .
- one battery 154 is coupled to the power distribution network 151 via an DC/AC converter 155.
- the vessel's 100 propulsion machines 156, 157 may further be operatively coupled to the power distribution network 151 .
- the propulsion machines 156, 157 are electric motors coupled via shafts to propellers 156a and 157a.
- This therefore provides advantages of, for example, reduced fuel consumption, reduced emissions, and/or longer battery life.
- the latter may be particularly advantageous on full-electric vessels (or hybrid-electric vessels with only minor emergency generator power).
- the vessel 100 comprises dual channels 1 12 and 142 connecting a lower part 1 10a of the first tank 1 10 to a lower part 1 1 1 a of the second tank 1 1 1 .
- a turbine unit 1 13 is arranged in channel 1 12, and one turbine unit 143 is arranged in channel 142.
- Channel 1 12 in this embodiment comprises a one-way valve 1 19 permitting flow only from the second tank 1 1 1 to the first tank 1 10, and channel 142 comprises a one-way valve 139 permitting flow only from the first tank 1 10 to the second tank 1 1 1 .
- each turbine unit 1 13, 143 can be optimised for the given flow direction, and avoids the need for the turbine unit 1 13, 143 to handle flow in both directions.
- An equivalent arrangement can be used for the air channel, i.e. the connection between the upper parts of the tanks 1 10, 1 1 1.
- the tanks 1 10, 1 1 1 and the channels 1 12, 122, 142 may be arranged spaced in a direction abeam the vessel 100, e.g. located on either side of the vessel.
- the channel 1 12, 122, 142 may extend between the tanks 1 10, 1 1 1 perpendicularly to the longitudinal direction (or nominal direction of travel) of the vessel 100.
- the stabilization arrangement may reduce roll motion, and generate power based on the roll forces acting on the vessel 100.
- the tanks 1 10, 1 1 1 may be spaced in a longitudinal direction of the vessel 100. This is illustrated in Fig. 8.
- the pitch motion of the vessel 100 may be damped and/or power may be generated based on pitch forces acting on the vessel 100.
- This embodiment may be particularly advantageous, for example, in stand-by or offshore supply vessels, which spend large amounts of operating time in stand-by mode. In this mode, the ship may control the yaw to weather vane into the incoming waves, thereby reducing roll, however the pitch motion may be a considerable discomfort for the crew. Further, according to this embodiment, the fuel consumption of the vessel 100 may be reduced during such stand-by mode.
- the turbine unit 1 13,123, 133, 134 can be a bidirectional turbine, i.e. a turbine configured for conversion of energy from an oscillating fluid stream.
- the turbine unit 1 13, 123, 133, 134 can be configured to have a fixed direction of rotation, independent of the direction of fluid flow through the turbine unit 1 13,123, 133, 134. This may be achieved, for example, by means of a Wells turbine or a Darrieus turbine. This provides the advantage that no moving parts are present in the channel 1 12, 122, 142 (with the exception of the rotary part of the turbine unit itself), which improves system reliability.
- the turbine unit 1 13, 123, 133, 134 may have a propeller 1 14 with variable pitch blades. The variable pitch blades may be actively controlled, or they may be passively controlled via the fluid stream, e.g. with a pivot so that the blades automatically turn in response to a change in fluid flow direction.
- the fluid turbine 1 14' has controllable-pitch blades.
- a pitch controller in this embodiment embedded in the control unit 125, controls the pitch of the blades. This permits the use of an optimal pitch for any operating condition, such as to maximize power generation or to obtain any desirable dampening performance by using the pitch to adjust the resistance for the fluid in the channel.
- the blades can be rotated at least 180 degrees. This allows the generator 1 15 to maintain a given rotational direction, while the blade pitch is used to account for directional changes in the flow. This allows a more optimized generator design, in that it does not have to be designed for oscillating operation with changes in the rotational direction.
- the pitch may be actively controlled via the pitch controller based on a sensor reading of the fluid flow in the channel 130, 131 .
- the sensor 127 may be a flow meter, or any other sensor capable of providing a signal which is indicative of the flow in the channel.
- the pitch can be passively controlled, i.e. that the fluid flow itself turns the blades as the fluid flow oscillates.
- FIG 10 shows a sectional, cut view of a vessel 200 according to one embodiment.
- the vessel 200 has a moon pool 210 enclosed within its hull structure, where the moon pool 210 permits access to, for example, lower equipment or tools through the moon pool 210 to a subsea location.

- the vessel 200 has first and second fluid channels 21 1 ,221 extending from the moon pool 210 to an outside of the vessel 200.
- the moon pool 210 is otherwise a substantially closed volume, being defined by the hull structure of the vessel 200 and the water 201 on which the vessel 200 floats.

This allows regulation of the resistance from the fluid turbine 214 on a fluid flow through the channel 21 1 ,221 , as well as optimisation of the operation of the turbine unit 213,223 so as to maximise power extracted.
- the fluid turbine unit 213,223 may further comprise a guide vane 226a, 226b arranged to guide a fluid towards the fluid turbine 214. This may be arranged so as to give a narrower or smaller flow path for the fluid past the turbine 214, and thereby improved performance in terms of, for example, power generated or controllability of the flow resistance.
- the vessel 200 comprises a ventilation shaft 230 having a valve 231 .
- the ventilation shaft 230 extends from the moon pool 210 to the outside of the vessel 200.
- an opening to the outside atmosphere can be selectively provided, for example to avoid (or reduce) pressure fluctuations in the moon pool 210 when workers are carrying out operations in the moon pool 210 area, or when no power generation through the turbine units 213,223 is required.
- the turbine units 213,223 and/or the channels 21 1 ,221 can be arranged so that they selectively provide a free opening to the outside atmosphere, for example by letting air bypass the turbine units 213,223, for the same purpose.
- the first fluid channel 21 1 comprises a first one-way valve 219 permitting flow from the moon pool 210 to the outside of the vessel 200 and the second fluid channel 221 comprises a second one-way valve 239 permitting flow from the outside of the vessel 200 to the moon pool

- the fluid turbine 214' has controllable-pitch blades.
- a pitch controller in this embodiment embedded in the control unit 225, controls the pitch of the blades. This permits the use of an optimal pitch for any operating condition, such as to maximize power generation to adjust the resistance for the fluid in the channel.

- the generator 315 is an electric generator, however other types of generators are also possible, for example hydraulic generators.
- the fluid turbine unit 313,323 may further comprise a guide vane 326a, 326b arranged to guide a fluid towards the fluid turbine 314.

- power such as electric power
- the channels 330,331 may be arranged at a front part or an aft part of the vessel 300. This may be particularly beneficial to utilise the effects of pitch motion of the vessel 300.
