Abstract: A bollard with a foot plate, a bollard pipe placed on the foot plate, and a bollard head placed on the bollard pipe. A measuring support is positioned in the bollard pipe, which measuring support carries a measuring instrument adapted to determine the position of the bollard head and/or position determination of an area of the bollard pipe below the bollard head at a height from the foot plate which amounts to at least 80% of the distance between the foot plate and the bollard head, the measuring support having a foundation which is separated from the foot plate.

Abstract: A tug (11) comprising a deck having an aft deck (16), a central deck (12) and a forward deck (15) and a rotatable towing installation (13) disposed on the central deck. The towing installation and central deck are sloping upwards from the aft deck to the forward deck with respect to a horizontal plane. The upward sloping angle (?) of the towing installation is at least 5 degrees. The design provides free towing all around in the horizontal plane in combination with sufficient bow height and buoyancy and in addition below deck space for e.g. additional accommodation.

Abstract: An all around towing system (33) for a tug (31) comprising a heavy plate (40) mounted on a deck of the tug, an upper rail segment (42) and a lower rail segment (44) disposed on the upper and lower surfaces of an outer edge of the heavy plate, respectively, a carriage (46) movable along the upper and lower rail segments, a set of bearing wheels (47, 48) arranged for guiding the carriage along the upper and lower rail segments, characterized in that the heavy plate further comprises respective upper and lower grooves (43, 45) on the upper and lower surfaces of the heavy plate, and in that the upper and lower rail segments are respectively mounted in the upper and lower grooves of the heavy plate.

Abstract: Pod drive which can be fitted to a vessel and which is provided with an electric motor which drives a propeller shaft which is likewise provided in the housing of the pod drive and is connected to a propeller which is situated outside the latter. It is proposed to use a fast-rotating electric motor in combination with a reduction gearing for driving the propeller shaft. The mounting of the propeller shaft is made particularly stable by mounting it on both sides of the electric motor. The reduction gearing may include a planetary system. The electric motor may be fitted next to the hollow propeller shaft. In this case, several electric motors can be arranged around the central propeller shaft. It is also possible to make the rotor of the electric motor hollow and to fit the propeller shaft inside the latter.

Abstract: A vessel and a method for driving a vessel. The vessel is provided with a pod arranged at the rear side thereof which is arranged rotatably with respect to the vessel. Rotation is effected about an axis which deviates slightly from the vertical. The axis of the propeller shaft forms an angle which is smaller than 90° with the axis of rotation of the pod. As a result of this combined positioning of the rotation shaft of the pod and the positioning of the propeller shaft, the axis of the propeller shaft with respect to the horizontal will vary when the pod is rotated depending on the rotation position of the pod. This permits optimum adaptation to the various operating conditions of the propeller position.

Abstract: Ship's winch including a frame which can be attached to a vessel and on which the cable drum and the motor driving the cable drum are provided. Adjacent to the cable drum, a slipping clutch is provided and between slipping clutch and the motor, a freewheel mechanism is provided which works towards the frame. The slipping clutch is embodied not to transmit further load to the freewheel mechanism or motor, respectively, in case of a certain overload caused by tension in the towing cable. In addition, by positioning the freewheel mechanism/clutch in this manner, the motor output for pulling in a certain load under greatly varying stresses can be reduced.

Abstract: Retaining device for a cable This consists of a rotary drum (2) around which at least two cable windings are made, retaining and paying out being possible by means of a motor (10) that drives the drum. According to the present invention the axis (12) of rotation for the drive is offset with respect to the axis of the drum, so that in a certain position the axis (12) of rotation is essentially coincident with the casing face of the drum engaging on the cable.

Abstract: The invention relates to the actuating device for a towing device, which can be rotated through 360 degrees in the horizontal plane, on a tugboat. The installation has a circular, flexible guide body, which is supported by one or more guide supports, around the axis of rotation of the towing device and one or more contact body (bodies). Changing the position of these components leads to the transmission of (contact) forces for actuation of the towing installation. Because of the circular shape of the guide body, the towing installation can be actuated simply and reliably irrespective of the rotational position.

Abstract: An emergency towing system for vessels. This system comprises a return guide fitted to the vessel to be towed; a closed ring-cable is fitted around this return guide, wherein this ring-cable comprises a coupling-member which, when the ring-cable is heaved around, establishes a connection with a contra-coupling-member on the vessel to be towed.

Abstract: Lifting hook having a control line connected by a resilient and smooth connecting piece to the end of a hook point. The control line is fed through the lifting eye or lifting sling(s) and by then pulling on the line a hook point will be guided by the connecting piece into the lifting eye or lifting sling(s) and hook into the latter.

Abstract: A tanker for carrying a liquid bulk cargo, provided with a full swash bulkhead. The bulkhead plating is closed watertight from deck to bottom except for one or more small holes (4) near the bottom.
