A bell nipple includes a downhole end configured to sealingly couple to an uphole-end of a blow-out preventer. An uphole end of the bell nipple includes a first set of threads along an inner surface of the bell nipple. A thread saver is configured to be received by the uphole end. The thread saver is configured to protect the first set of threads from impact. An extension sub is configured to be received by the uphole end. The extension sub includes a downhole end with a second set of threads configured to engage with the first set of threads. An uphole end of the extension sub includes a third set of threads configured receive a well tool.

A well pad construction system includes a construction area, surface compaction equipment to compact the construction area, an excavator disposed at the construction area and movable to generate an excavated area, a cellar disposed in the excavated area, controlled low-strength material (CLSM), and backfill equipment disposed around the excavated area. The backfill equipment is moveable over the construction area to pour CLSM into a gap between the cellar and surrounding medium in the excavated area for holding the cellar in place and providing a firm well pad from which a rig may operate.

A subsea housing assembly, in particular for a subsea sensor, is provided. A subsea housing includes a first housing portion and a second housing portion. The first housing portion includes a first electrical connection for data communication and the second housing portion includes a second electrical connection for data communication. A wall provides separation between the first housing portion and the second housing portion of the subsea housing. An inductive coupler, that includes a first coupling section disposed in the first housing portion and a second coupling section disposed in the second housing portion, is provided. The inductive coupler is configured to provide inductive coupling across the wall for providing at least a data communication between the first and second electrical connections.

The present invention relates to an upper subsea wellhead surface joint, a lower subsea wellhead surface joint, an upper subsea wellhead conductor joint, and a lower subsea wellhead conductor joint. According to the present invention, these are machined from a single piece of forged steel material and corrosion protected by means of an electrolytic or other process.

A subsea assembly includes a housing having a flange interface for interfacing with a flange of a process fluid carrying component, wherein the housing is configured such that boltheads or nuts exerting a fastening force on the subsea assembly when mounted to the process fluid carrying component are spaced from the flange interface so that the dimensions of the housing of the subsea assembly at the flange interface are not affected by a space required for a bolthead or nut fastening tool.
