Assignee:

INTEROCEAN SYSTEMS, INC. - SAN DIEGO CA

International Classification:

US Classification:

Abstract:

Apparatus for detecting the presence of a targeted group of hydrocarbons, such as diesel/fuel oil, lube oil, motor oil, hydraulic oil, jet fuel, mineral oil and crude oil in a highly reliable manner even though present at only extremely low concentration. A high power, pulsed light source is focused into a collimated beam that is reduced by a set of filters to a band of pulsed light within a precise set of wavelengths and directed vertically onto a target surface, such as a body of water. All but a precise band of light wavelengths returning to the apparatus are blocked so that substantially all light which then reaches an internal photodetector is within such precise band of wavelengths; as a result receipt of such light programmed intervals following such pulses is indicative of the presence of a member of the targeted hydrocarbon group.

International Classification:

B63B 21/20
F16G 15/04

Abstract:

A release mechanism for separating sections of mooring lines has a main body with two separable first and second halves or sections. A hydraulic assembly within the main body is controlled by an acoustic system, and moves a rod and button so as to move locking shoes within the main body. The locking shoes hold the first and second sections locked together, or alternatively release them to disconnect the mooring line. In addition to the acoustically controlled hydraulic assembly, the release mechanism has a mechanical disconnect, which is operated by pulling the release mechanism into a chain fairlead or the like, or by pulling an encircling member such as a trigger sleeve into the release mechanism. The release mechanism may include instrumentation to transmit various operating conditions of the release mechanism when in use.

Abstract:

Some embodiments provide ocean rig releases apparatus, systems and methods. In some implementations, a rig release apparatus comprises: a body having a first and second mating sections each being connected to one of two separate tethers; at least one locking shoe movably secured with the first mating section and movable between a first position configured to secure the first mating section and the second mating section together and a second position configured to allow the first mating section and the second mating section to separate; and a locking system configured to releasably lock the first and second mating sections and prevent hydrostatic pressure created by ocean depths from inadvertently unlocking, wherein the locking system comprises: a restraint system that inhibits the movement of the at least one locking shoe, and comprises a stop element that when released physically retracts to unlock the locking system allowing.

International Classification:

B63B 21/08

Abstract:

Some embodiments provide release apparatuses comprising: a body having a first and second mating sections each connected to separate tethers; the first mating section comprising a plurality of movable locking shoes movable between a locked position and a release position configured to allow the first mating section and the second mating section to disconnect; and a hydraulic system configured to induce a force to cause movement of the locking shoes between the locked and release positions, the hydraulic system comprises: a hydraulic fluid source; a hydraulic conduit coupled with the hydraulic fluid source; a hydraulic cylinder coupled with the hydraulic conduit and configured to receive hydraulic fluid; and a bypass valve coupled along the hydraulic conduit and configured to transition between open and closed states in response to pressure within the hydraulic conduit exceeding a hydraulic threshold and to allow leaked hydraulic fluid to be drained.
