A fitting for connecting a branch conduit to a liner installed in a main pipe is configured to mechanically connect to the branch conduit as it is inserted into the branch conduit from inside the main pipe. The mechanical connection is established without rotating the fitting. The fitting can include a body having an outer shaft section for being received in the branch conduit and an inner flange section for opposing the liner within the main pipe. The fastener include one or more teeth that extend radially from the exterior of the shaft section. The teeth can be secured to the shaft section by deforming portions of the fitting body against the teeth. The flange section supports a gasket for sealing against the liner when the fitting is installed. The flange section can include a rim that maintains the gasket in the proper position.

A multidirectional runner assembly for positioning a carrier pipe within a surrounding casing pipe. Each multidirectional runner assembly has at least one ball transfer assembly at least partially protruding from the runner assembly, in order to contact an inner surface of a surrounding casing pipe. The ball transfer assemblies reduce static and/or kinetic friction forces during installation of a carrier pipe within the central bore of a casing pipe, permit multidirectional orientation of the runners within the casing pipe, and provide greater load support.

The connection assembly (100) which includes a flange (140) has two internal orifices (150) crossing through and centered on orifice axes (A150) parallel to each other, a front surface (142) and a rear surface (144) parallel to a transverse plane (P140) transverse to the orifice axes (A150), two fluidic coupling elements (170), that have a male body (172) received in a corresponding internal orifice, and a cover (120), configured for being attached to a support (110) in a mounted configuration of the connection assembly. The flange can move with respect to the cover according to a movement supported by the transverse plane, whereas for each male body, a second gasket (188) is interposed radially between the male body and an internal radial surface (S162) of the corresponding internal orifice, each male body being mounted in the corresponding internal orifice and can be tilted with respect to the corresponding orifice axis.

A subsea distribution equipment assembly includes a modular structure with a block having a metallic structure and panels that allow the configuration for several pieces of equipment, in such a way that both the hydraulic instrumentation and the electrical instrumentation are also modularized. A method of assembly a subsea distribution equipment assembly includes transporting a first block and a second block using a crane of a vessel, aligning and connecting eye joints installed on each of the first and second blocks, connecting a foundation to the first and second blocks using the crane and a trolley, and installing an umbilical termination assembly jumper between the first and second blocks.

Parts of a first coupling and a second coupling that protrude from manifold blocks each have the shape of an elongated tube. When the first coupling and the second coupling are viewed in the axial direction, the traverse direction of the first coupling and the second coupling agree with the arrangement direction of manifold blocks. A part of the tube insertion hole is a small diameter hole, which is a stadium-shaped hole. When the first coupling and the second coupling are viewed in the axial direction, the traverse direction of the small diameter hole agrees with the traverse direction of the first coupling and the second coupling.

An adapter and adapter system for connecting a female end of a first chimney portion to a male end of a second chimney portion. The adapter includes a first radial adapter portion with a first inner surface and a first outer surface extending along a first axis and wherein the first inner surface and the first outer surface are substantially coaxial. The adapter further includes a first locking interface protruding outward from the first outer surface and configured to engage with a first locking interface of the first chimney portion and a second locking interface protruding inward from the first inner surface and configured to engage with a second interlocking interface of the second chimney. The first outer surface of the adapter is configured to be received within the female end of the first chimney portion and the inner surface is configured to receive the male end of the second chimney.
