摘要： Techniques are disclosed relating to marine geophysical surveys. Various output characteristics of a vibratory source may be modified based on whether a source is targeting an identified portion of a survey area. The portion of the survey area may be detected during the survey or may be pre-identified. In some embodiments, a survey system drives a vibratory source using digital codes having different lengths based on whether the source is targeting an identified portion of a survey area. The disclosed techniques may improve imaging of geology under certain types of formations or may reduce environmental impact, in various embodiments.

摘要： A tugboat for assisting a marine vessel to maneuver. The tugboat boat comprises an engine driving one or more propulsors with a controllable direction of thrust, a towing line for establishing a pulling connection between an assisted vessel and the tugboat, a first sensor arrangement configured for sensing the size and direction of the pulling force that the towing line exerts on the tugboat, a second sensor arrangement configured for sensing the orientation of the tugboat, a controller in receipt of a signal from the first sensor arrangement and in receipt of a signal from the second sensor arrangement. The controller is informed of the size and direction of thrust generated by the one or more propulsors, and the controller is configured to determine if a safety threshold is exceeded on the basis of: sensed size and direction of thrust, sensed size and direction of the pulling force, and sensed orientation of the tugboat.

摘要： An emergency ship arrest system includes a vessel attachment system, a retrieving system, and an anchor system. The vessel attachment system is configured to connect to a vessel at sea, and includes a bridle system and a hawser line. The bridle system is operatively connected to the hawser line's proximal end. The bridle system is configured to engage at least four fittings on a foredeck of the vessel to distribute the load over the foredeck. The retrieving system includes a retrieving line with a proximal end that is detachably connected to the hawser line's distal end in a setup position. The anchor system includes a main rode and a para sea anchor. The main rode's proximal end is detachably connected to the hawser line's distal end in an anchor position.

摘要： The towing system for a tugboat consists of a ring arranged on the deck of the tugboat along which a cart moves on which a winch is arranged. At a larger diameter of the ring manufacturing inaccuracies of the cart respectively the ring respectively deformations can be absorbed in a particularly efficient way by arranging springs between the wheels that engage the ring-shaped base and the cart on which the wheels are arranged. In particular, such springs are rubber springs such as neoprene springs. These can be arranged as blocks, bushes or the like. Preferably, the cart includes a relatively stiff box on which a winch and, more in particular, an electrical winch is arranged. In particular, the cart is a ring, extending around circumferentially.

摘要： An airborne tugboat with three hulls (4): an underbody (4), surface body (5) and inflatable body (6). When stationed on shore the inflatable body is not activated, but is folded up against the surface body. Gas turbine (1) drives the propeller (3) via the reduction gear (2). The rotatable ring (8) round the propeller makes the airborne tugboat maneuverable, and when the disabled ship is towed, it will be able to influence towing direction without the risk of the airborne tugboat heeling over. By its design the airborne tugboat should be regarded as a slow-moving towing boat where the speed is low but the power in the towing direction is great. The design is characterised by low weight in all machinery and equipment. The amount of fuel restricts the operating time, but the helicopter and airborne tugboat, for example, use the same fuel, thus providing the advantage that the helicopter can refuel the airborne tugboat before it returns to base.

摘要： A method for intercepting and yawing an errant sailing vessel is disclosed, wherein the vessel might have been hijacked or malfunctioned and in danger of colliding with an object. The method comprises dispatching a pair of watercraft to approach said sailing vessel, providing a tow rope to be secured at one end to first watercraft and the other end to second watercraft. The tow rope is brought to extend between the first and second watercrafts over the hull of said sailing vessel. The first watercraft is then secured to one side of said sailing vessel's hull, while second watercraft pulls the tow rope away from the direction of sailing on the other side of said vessel's hull. In an alternative embodiment, the tow rope end held by the first watercraft may be secured directly to the vessel's hull, thus freeing the first watercraft to evacuate crew from the vessel to a safer distance.

摘要： A device for determining the position of a meridian which includes a gyroscope mounted on a horizontal axis and which is supported so that it tends to point north. The gyroscope is suspended on a suspension wire and the torque in the suspension wire is balanced with the north-seeking action of the gyro rotor. The torsion in the suspension wire is removed by rotating the gyro case and thus aligning the spin axis of the gyro with true north. A disc is attached to the case of the gyroscope and is immersed in a viscous liquid so as to damp the north-seeking action of the gyroscope. The elevation of the container for the viscous liquid is adjustable to vary the degree of immersion of the disc, which is downwardly tapered so as to vary the damping torque with the degree of immersion.
