    CREW TRANSFER VESSEL COMPRISING AND ACCESS BRIDGE SYSTEM AND METHOD FOR TRANSFERRING PEOPLE AND / OR GOODS TO AND / OR FROM SUCH CREW TRANSFER VESSEL
    The present invention relates to a (crew) transfer vessel including an access bridge system configured for providing access and egress to a unit, such as a work vessel, service and maintenance vessel, unit or vehicle, offshore structures including platforms and wind turbine foundations.
    Conventional crew transfer vessels are also referred to as fast crew supply vessels or accommodation service vessels. These crew transfer vessels are built to transfer people and / or goods, also referred to as cargo, and move with a relatively high speed to a desired location. These conventional vessels can be provided with an access bridge that includes a gangway and associated equipment. At the desired location the gangway is connected to the specific unit, such as an offshore structure. Typically, these vessels have been designed to be relatively light and are, there for, sensitive to undesired movements and / or disturbances, especially around the roll axis. In practice, this significantly reduces the operational window in which the vessel can be used for transfer of people and / or goods, reducing the overall efficiency and increasing cost.
    The object according to the present invention is to obviate or reduce the afore-mentioned problems, and to provide easy and safe access and egress to and from an accessed unit, preferably in an enlarged operation window.
    This object has been achieved with the vessel for transferring crew and / or goods, such as a crcw transfer vessel, the vessel according to the invention including an access bridge system, including:
    a gangway having a first end that is connected to the vessel and a second end configured to be connected to a floating or fixed offshore structure or quay side; a telescopic module configured to adjust the height of the gangway;
    a roll compensation system configured for compensation of undesired movements and / or disturbances on the roll axis of the vessel acting on the gangway, the roll compensation system comprises:
    a roll compensation frame configured for compensation on the roll axis of the vessel; and a drive system for driving the roll compensation frame having at least one roll compensation actuator such that undesired movements and / or disturbances on the roll axis of the vessel can be compensated, w'herein the actuator acts on the roll compensation frame enabling independent compensation of the undesired movements and / or disturbances on the roll axis of the vessel.
    The crew transfer vessel allows transfer of people and / or goods between the vessel and a further accessed unit, such as an offshore structure, including an oii platform, dock, vessel, wind turbine etc., or quay side. The access bridge system comprises a gangway having a first end that is connected to the vessel and a second end that is preferably provided with a landing tip. This second end is configured to be connected to the accessed unit, such as an offshore structure or quay side. The gangway preferably involves a number of telescopic gangway elements to enhance the flexibility and operational functionality of the vessel.
    Providing a roll compensation system allows compensation of undesired movements and / or disturbances on the roll axis of the vessel. These undesired movements and / or disturbances act on the gangway. Such a roll compensation system comprises a roil compensation frame that allows the actual compensation on the roll axis and a drive system driving the compensation frame. The drive system is provided with at least one roll compensation actuator such that undesired movements and / or disturbances on the roil axis of the vessel can be compensated.
    This roll compensation system is configured for independent compensation of the undesired roll movements and / or disturbances on the roll axis of the vessel. This allows for independent and relatively fast compensation. This increases the operational window for transfer of people and / or goods under a wider range of weather conditions. This is more efficient and more cost effective as compared to conventional systems.
    The access bridge system comprises a telescopic module configured to adjust the height of the gangway. Providing a telescopic module enabling adjusting the operational height of the gangway relative to the desired location. For exampie, this may involve height adjustments at 1525. above sea level. It will be understood that other dimensions can also be envisaged in accordance with the invention.
    In a preferred embodiment of the invention the roll compensation system is configured for compensation over a roll compensation angle in the range of -5 ° to + 5 °, preferably in the range of -4 ° to + 4 °.
    Providing a compensation angle in one of the specific ranges allow an effective control and compensation of the undesired movements and / or disturbances on the roll axis of the vessel.
    In a presently preferred embodiment of the invention, the telescopic module comprises a height adjustment drive and a height compensation drive.
    Providing a height adjustment drive (static) setting an effective height adjustment of the gangway relative to the offshore structure or quay side. Such a height adjustment drive can be embodied as a hydraulic cylinder capable of achieving the desired height adjustment. It will be understood that other expired can also be envisaged. When providing a height compensation drive and / or undesired movements acting on the effective height can be (dynamically) compensated by this compensation drive. This height compensation drive is preferably embodied as a relatively small hydraulic cylinder, preferably narrower than the height adjustment drive cylinder, to improve the speed and / or accuracy of the actual compensation.
    In a presently preferred embodiment the bridge with the gangway is provided with one or more hydraulic cylinders that are capable of positioning the gangway at an angle relative to the horizontal. This further enhances the possibilities for height adjustments.
    In a further preferred embodiment of the invention, the crew transfer vessel further comprises a compensation system that is configured for compensation of undesired movements and / or disturbances on the yaw axis and / or pitch axis.
    Providing a separate compensation system for the yaw axis and / or pitch axis allows effective compensation of the gangway around these respective axes. These compensation system or systems are preferably independently operated from the roll compensation system according to the present invention. These independently configured compensation systems enable fast and accurate control and compensation.
    In a further preferred embodiment of the invention, the roil compensation frame comprises a support that is connected to a roll compensation hinge.
    Providing a roll compensation allows an effective compensation around the roll axis. Preferably, the roll compensation hinge is positioned in or close to the roll axis of the vessel, more preferably the roll compensation hinge is positioned substantially co-linear or substantially parallel to this roil axis.
    In a more specific embodiment of the present invention the roli compensation hinge comprises a shaft that extends considerably along this roll axis. This allows effective and fast compensation or undesired movements and / or disturbances on the roll axis of the vessel.
    Furthermore, by providing the hinge along or close to the roll axis the required forces for the actual compensation remain limited. This allows an effective and cost efficient roll compensation system. In addition, accelerations acting on people on the bridge / gangway are reduced.
    In a preferred embodiment, the drive system comprises one or more, and preferably two, sub-actuators acting in different positions on the support to control the angle of the support.
    The support preferably comprises a pole or post that specifically comprises a telescopic module. This support can be rotated in this embodiment along the roll compensation hinge using the one or more sub-actuators. Optionally, the sub-actuators include a number of drives that act somewhere along the length of the support. For example, in a presently preferred embodiment, the one or more sub-actuators act on a distance or at least 2 meters, preferably at least 5 meters, from the roli compensation hinge. For example, the role compensation hinge is positioned at the tank top of the vessel and the sub-actuators are provided at one of the other decks of the vessel. This provides an efficient moment of force acting on the support / actuator.
    In an alternative embodiment of the invention the roll compensation frame comprises a. Portal frame having at least two supports that are connected to the vessel at respective connection hinges that are positioned at opposite sides of the vessel.
    By providing a portal frame for an alternative role compensation frame can be mounted on a crew transfer vessel. This frame can also be applied to other service vessels. The gangway is preferably connected to a platform that is supported by at least two side supports or the portal frame. Preferably, the drive system comprises two compensation cylinders (dynamic) for enabling roll adjustment and two height adjusting cylinders (static) for height adjustment of the gangway. The height adjusting cylinders enable adjustment of the effective height of the gangway relative to the desired location. The compensation cylinders enable compensation for undesired movements and / or disturbances acting on the roll axis of the vessel.
    The invention further relates to a method for transferring people and / or goods to anchor from a crew transfer vessel in one of the inventive, the method including the steps of:
    positioning the vessel relative to an offshore structure or quay side; connecting the gangway to the offshore structure or quay side; compensating undesired movements and / or disturbances on the roll axis with the roll compensation system; and transferring the people and / or goods.
