Ensco | Date: 2016-07-25

Techniques and devices to assist an offshore unit in going on location and coming off location. A device may include an interface configured to receive a signal indicative of motions of an offshore unit. The device may also include a memory configured to store a set of values corresponding to acceptable motions of the offshore unit, as well as a processor configured to determine if a measured motion of the offshore unit exceeds at least one value of the set of values and generate an indication that going on location by the offshore unit can be undertaken when the processor determines that the measured motion of the offshore unit is less than or equal to the at least one value.

Techniques and systems to couple a high pressure casing string to a blowout preventer or a subsea shut-in device. A device includes a locking mechanism configured to interface with a terminal end of a casing string of an offshore platform to couple the device to the terminal end of the casing string. The device also includes a sealing mechanism configured to fluidly seal an area around the terminal end of the casing string, wherein the locking mechanism and the sealing mechanism are disposed at separate positions along a vertical orientation of the device.


Techniques and methods to reduce downtime in an offshore platform, such as an offshore semi-submersible drilling rig or drillship. Through the use of one or more movable platforms in a moon pool area, work on a riser string passing through the moon pool area may be performed without exposing workers directly to the open sea below. Accordingly, the use of the one or more movable platforms in the moon pool area may provide protected access to the riser string during, for example, harsh weather conditions.

An automated pipe tripping apparatus includes an outer frame and an inner frame. The inner frame includes a tripping slips and iron roughneck. The automated pipe tripping apparatus may, in concert with an elevator and drawworks, trip in a tubular string in a continuous motion. The tripping slips and iron roughneck, along with the inner frame, may travel vertically within the outer frame. The weight of the tubular string is transferred between the tripping slips and the elevator. The iron roughneck may make up or break out threaded connections between tubular segments, the upper tubular segment supported by the elevator and the lower by the tripping slips. An automated pipe handling apparatus may remove or supply sections of pipe from or to the elevator. A control system may control both the automated pipe tripping apparatus and the elevator and drawworks.


Patent
Ensco | Date: 2016-04-07

Techniques and systems to reduce deflection of a riser extending from offshore platform. A riser may include an outer enclosure. This outer enclosure may be coupled to a current deflector. The current deflector is configured to generate a lift on the riser in response to a fluid flowing across the current deflector. This lift that is generated by the current deflector may counteract currents or other factors to mitigate deflection in the riser.


Patent
Ensco | Date: 2016-04-07

Techniques and systems to reduce deflection of a riser extending from an offshore platform. The riser may include a flow guide. The flow guide may receive a fluid. The flow guide may also include one or more outlets that are configured to transmit the fluid. This transmission of the fluid by the one or more outlets may counteract currents or other factors to mitigate deflection in the riser.


Patent
Ensco | Date: 2016-04-07

Techniques and systems to reduce deflection of a riser extending from offshore platform. The riser may be coupled to a seafloor and may experience movements due to, for example, currents. A riser restraint device may be utilized to reduce these movements of the riser. This riser restraint device may be coupled to the seafloor. This coupling of the riser restraint device may aid in allowing the riser restraint device to reduce movement of the riser and, thus, reduce deflection of the riser.


Patent
Ensco | Date: 2015-10-27

Techniques and systems to reduce contact of a cable with a top drive. A cable guide may be mounted to one or more bails supporting the top drive and may operate to extend a distance between a cable passing along a length of the top drive. The cable guide may include both an upper guide assembly and a lower guide assembly. Each of the upper guide assembly and the lower guide assembly may both be coupled to one or more bails supporting the top drive in a serial manner.


Patent
Ensco | Date: 2016-07-13

Techniques and systems to reduce movement of at least one portion of an offshore platform. One portion of the offshore platform can provide a connection to a seafloor. A second portion of the offshore platform provides a lateral force to the first portion of the offshore platform while allowing for vertical movement between the first portion and the second portion of the offshore platform.
