| 227 | Soft Landing System and Method of Achieving Same | US14589472 | 2015-01-05 | US20150114657A1 | 2015-04-30 | Ronald Baker; Pradeep Dhuper |
| A subsea wireline system for soft landing equipment during installation. The subsea soft landing wireline system includes coarse alignment members that can be part of a tree and interact with a funnel located on the equipment to be installed by the soft landing system. Smaller alignment members can provide fine alignment and also interact with a funnel located on the equipment to be installed. The funnels are used to trap sea water that provides a cushion for the equipment being installed. Once in alignment, trapped water can be released from the funnel via a restricted orifice or a control valve located on an ROV. The system achieves soft landing without the use of a running tool, thus reducing expense. | ||||||

| 238 | Guide line attachment | US540716 | 1990-06-20 | US5107930A | 1992-04-28 | Hans P. Hopper |
| A guide line attachment for releasably attaching a guide line to a guide post top or other portion of a sub-sea installation has three relatively movable spring loaded concentric sleeves, the relative movement of which can be used to releasably lock the attachment to the guide post top or other portion. Relative movement of the sleeves also activates a latch to releasably lock the sleeves to each other. The attachment may fit inside or outside a guide post top and may be pre-set so that it will or will not automatically relatch on release. The guide post tops have internal or external grooves for engaging the attachment locking means, and specially designed tools may be used to effect remote release sub-sea. The guide line attachment may be used for all stages of the drilling and production of a sub-sea oil well and avoids the present need to cut and replace guide lines at different stages in the life of a sub-sea well. | ||||||
| 239 | Undersea package and installation system | US598738 | 1990-11-28 | US5088558A | 1992-02-18 | Frank Mohn |
| An operational package comprising either a pump/driver package (1; 100) or a valve package (250) is retrievably installed at a subsea station by a receptacle (10; 110; 251). Co-operating connection means on the package and the receptacle establish fluid and/or electrical connection between the package and the receptacle on reception of the package within the receptacle. Seal means (14) carried by the package are moved into a condition to seal any such fluid connections. Installation is effected by establishing a running loop extending from a surface vessel downwardly through the receptacle (10; 110) and upwardly to the surface vessel outside the receptacle, the package (1; 100) being moved on and guided by the wire loop from the surface vessel into the receptacle. Alternatively, a handling tool (120) is employed with co-operating releasable connecting means (151) on the handling tool and the receptacle, and operating means (124, 125) operable between the handling tool and the package to effect movement of the package inwardly of the receptacle, after connection of the connecting means. | ||||||
| 240 | Subsea payload installation system | US588070 | 1990-09-25 | US5069580A | 1991-12-03 | Harry A. Herwig; Doyle D. Hickok |
| Improved methods and apparatus are provided for landing and securing a payload to a subsea assembly, such as a hydrocarbon recovery assembly, utilizing a surface vessel and a subsea ROV. The payload is suspended from a submersible payload package, and the package and payload are lowered subsea by a vessel cable. Guide cables extending from the package may be secured to the subsea assembly, and a floatation device thereafter activated to render the package positively buoyant, thereby making the guide cables taunt and relaxing the vessel cable to de-couple the package and payload from the surface vessel. The guide cables are then used to lower the payload from the package onto the assembly, and the payload secured to the assembly with the ROV. The floatation device is subsequently deactivated such that the pacakage is no longer positively buoyant, thereby re-coupling the package to the surface vessel. | ||||||
