Cable Protection System
A power cable or umbilical with a cable protection system for stabilising a submarine power cable or umbilical in the free span between an offshore installation and the seabed. An offshore transfer system has an offshore structure, a power cable or umbilical and a receiving structure, the power cable or umbilical being protected in a non-supported section by such a cable protection system.
Cable Connector Attachment
A cable connector attachment is provided, the attachment including at least a hose fitting, wherein said hose fitting is swedged into an associated cable and threaded into a CCP; and a set screw, wherein said set screw is inserted into the hose fitting to ensure the CCP cannot vibrate loose. Optimally the set screw is a tapered screw, so that greater force is applied to the terminus end. A braided hose is disposed in mechanical communication with a stainless hose fitting and secured using one or more fasteners. The hose is securely pressed completely inside the stainless hose fitting and then crimped, and a status signal is optimally provided by a crimp machine when a predefined crimp has been completed, thereby notifying the operator of such status. Optimally the crimp measures between about 1.1-about 1.2 inches.
UNDERWATER CUTTING DEVICE
A cutting device to sever a cable or the like. The cutting device can be used to sever the cable or the like in relatively inaccessible locations, such as in the ocean. The cutting device can include one or more springs that can be loaded to facilitate the deployment of a cutting tool to sever the cable or the like. The cutting device can include a lever than can be rotated between a locked configuration impeding deployment of the cutting tool and an unlocked configuration permitting deployment of the cutting tool. A linkage can retain the lever in the locked configuration. The linkage can be compromised, permitting the movement of the lever into the unlocked configuration.
APPARATUS
An annular seal member comprising a seal body comprising a locating portion locatable against a wall element of an offshore structure, an inner surface, an outer surface and a lip portion that defines an open mouth of the seal member for receiving an elongate element therethrough; wherein the seal body is locatable against the wall element such that when a static pressure acting on the outer surface of the seal body exceeds a static pressure acting on the inner surface of the seal body a net positive pressure is exerted on the outer surface which at least partly deforms inwardly to provide a portion of the seal body for sealing against an outer surface of the elongate element. An offshore structure.

Apparatus for locating elongate object in a trench in a floor of a body of water
An apparatus for locating an elongate object in the seabed is disclosed. The apparatus comprises a body and a pair of jetting swords arranged on lateral sides of the elongate object to form a trench in the seabed. Chain cutters arranged on lateral sides of the elongate object cut respective parts of a trench in the seabed and are moveable relative to the body between a stowed position and a deployed position, independently of the jetting swords.
Method and Apparatus for Inserting an Elongate Object Into a Trench in a Sea Floor
A vehicle (2) for deploying a cable (4) into a trench (8) in the seabed (10) is disclosed. The vehicle (2) comprises a body (12) adapted to move relative to the trench (8) in the sea bed (10), and a bellmouth (18) for engaging the cable (4) and mounted to the body, wherein the bellmouth (18) is adapted to define an open channel (20) in a direction facing the trench (8) for engaging the cable (4).

INTRODUCING AN ELONGATED ELEMENT INTO A SUBMARINE DUCT
Method for installing an elongated element, in a submarine duct, the submarine duct having an entry port and an exit port located in outer liquid (OL) at a second depth,
the method comprising the steps of: introducing the elongated element into the entry port, introducing propelling liquid (PL) into the entry port,
characterized in that the method comprises a step of sucking propelling liquid (PL) out of the exit port of the duct with an immerged suction pump being operated at a predetermined suction pressure drop (ΔP.sub.pump) of propelling liquid (PL) so that the predetermined suction pressure drop (ΔP.sub.pump) applied to propelling liquid (PL) is smaller than a hydrostatic pressure (P.sub.hydro) of the outer liquid (OL) at the second depth.
