Abstract:
The invention encompasses fire-escape models of off-shore rigs with emphasis on a 'Detachable Island Rig' (DIR.) instantly unlocked upon a rig-fire, from a permanent 'under- water basement', saving property and personnel. The devised 'water-seal' of its basement's 'in-situ' 'fire-escape' entry, not destroyed upon a rig-fire, serves as an exceptional model (named 'Sumathi Paturu in-situ model', after its inventor) for an 'in-site' fire-escape with similar 'water-seal' for jack-up rigs with no basements. An 'off-site' modular is an unlimited air-source for all 'fire-escape' units. A 'spray-room' with converging 'spray-walks', or 'spray-tracks' with 'track-drives' or else a simpler means of 'spray-drives' are safe evacuation accessories workable even with minimal expendable cost and space. In the foregoing, vital needs like safe evacuation, food, and fresh air are devised as affirmed provisions. The wheeled 'life-boats' and 'lift-boats' are let out boarded or un-boarded, by click of a remote control, with no sustainable collision injury.
Abstract:
A Floating Production, Storage and Offloading (FPSO) surveillance system (7) is equipped with an adjustable alarm threshold that suppresses nuisance alarms if liquid level variations in FPSO crude oil and/or other liquid storage tanks (6) monitored by the system do not exceed estimated oscillating liquid level variations due to oscillating motions of the FPSO unit (1) during severe weather conditions.
Abstract:
The invention relates to a drillship, comprising a hull (2) which extends along a longitudinal axis (X) between a bow (3) and a stern (4). The ship (1) comprises at least three separate operating zones distributed between bow and stern along the axis (X): -a first operating zone (10) of ship management, in which the safety and abandon ship means are stored; - a second operating zone (20) of drilling; and - a third operating zone (30) of power generation. The second operating zone (20) and the third operating zone (30) being connected to the first operating zone (10) by two longitudinal lateral corridors (41) and (42), made under the main deck, each of which extends beside a ship side (5, 6). Said two longitudinal corridors (41, 42) are connected to each other transversally by one or more transversal corridors (51, 52, 53), each of which extends from one ship side to the other under the main deck.
Abstract:
The present invention relates to a system of remotely controlling and monitoring crafts by means of a wireless communication network. More particularly, the present invention relates to a system that enables one to monitor and control the navigation and safety of a craft, in addition of its entertainment and comfort pieces of equipment, from a remote terminal such as, for example, a cellular telephone connected to a wireless communication net work provided by a cellular telephony operating company. Thus, one describes a system particularly employed for remotely controlling and monitoring crafts (100), the craft (100) comprising at least one control panel (101 ), the craft (100) being accessible by at least one remote terminal (300), through a wireless communication network (400), the remote terminal (300) characterized by being provided with a simulating software (113), which interacts with at least one user through an interface that reproduces graphically the control panel (101 ).
Abstract:
The present invention discloses an apparatus for changing the direction of travel of a sailing vessel. The apparatus consists of a watercraft (10) with moveable flaps (12A, 12B, 12C) internal ballast tanks, solenoid banks (20) and explosive activated nut and bolt clamps. The watercraft (10) is manually navigated or remote control. A method of utilizing the watercraft (10) to retard and/or change the direction of travel of the sailing vessel is disclosed.
Abstract:
The invention relates to providing an ice load monitoring system (500) for monitoring ice-induced loads on a structure of a vessel (501). The vessel structure comprises typically at least a shell plate (102), vertical frames (106) essentially normal to the shell plate (102) and longitudinal frames (104) essentially in the horizontal plane and normal to the shell plate (102). Further the ice load monitoring system comprises a combination of stress sensors (F, S, P) each of which is adapted to convert deformations of the structure into a signal proportional to the deformations. The combination of sensors comprises at least frame bending stress sensors (F), plate stress sensors (P) and frame force sensor (S). The ice load monitoring system (500) comprises also a data processing unit (506), and an information network (508) connecting the sensors (S, P, F) and the data processing unit (506). The data processing unit (506) is adapted to collect the signals from the sensors (S, P, F).
Abstract:
The invention relates to a data acquisition system for use on board a vessel or installation in order to provide basis data concerning the individual hull's response to the individual wave in order to provide an early warning of the risk of waves, which may cause water to wash over the deck of the vessel, resulting in damage to deck equipment, the hull and/or cargo, and which may cause powerful impacts against the bottom of the hull.
Abstract:
A method for detecting the ingress of liquid into an empty elongate hollow structure such as a support for an offshore platform which is at least in part submerged in a liquid. Sound is introduced into the structure by a sound generating device mounted within the hollow structure, the device comprising sound generating means and liquid detection means. When the liquid detection means detect an ingress of liquid into the structure, the sound generating means generate a sound in response to this detection. The generated sound propagates through the structure and sound is detected, and detection of the sound giving an indication of liquid ingress into the structure.
