B-CON Misalignment Ball Connector

The B-CON is designed for piping and pipeline systems where the connector must compensate for misalignment of the pipe . The B-CON significantly reduces the time required to install subsea pipeline connections by providing a leak tight metal seal with performance characteristics and versatility that exceed those of welded pipe or conventional flanges. While primarily intended for subsea piping operations, the B-CON is a valuable piece of equipment in any application (above or below water) where misalignment of the pipeline is a problem .

The unique design of the B-CON connectors metal seal allows for up to +/-10 of misalignment in any axial plane from the centerline of the adjoining pipe (20 total misalignment) . The metal sealing criteria is the same as that specified by ASME for the ring-joint flanges. Sealing integrity is maintained at any angle of misalignment, with the seal being insensitive to externally applied bending loads at all operating pressures . It is actuated by tightening of the bolts . The tightening locks the ball member into the socket flange, creating a rigid, static leak tight seal .

The B-CON meets all Applicable Codes and Standards: ANSI, API, ASME and NACE and

it is available in stock from pipe sizes ranging from 4-in Nominal Pipe Size (NPS) to 24-in NPS and in pressure Classes 600 & 900 . The B-CON can also be supplied for any pipe size and any pressure rating, upon request .

Swivel-Ring FlangeOceaneerings Swivel-Ring Flange assembly provides easy alignment of the bolt holes during makeup to a common flange such as those defined by ASME B16.5, MSS SP-44 and API 6A .

Alignment is an important and critical feature when bolting subsea pipeline flanges together. The outer ring flange of the Swivel-Ring Flange assembly is held in position by a retainer ring that freely rotates around the inner weld-neck hub for quickly positioning the bolt holes of the two joining flanges.

Smart Clamp - Diver Installable

Permanent Pipeline Repair ClampOceaneerings Smart Clamp is a diver installable split mechanical fitting used to repair a damaged or leaking subsea pipeline . The fitting eliminates costly pipeline shut downs and expensive hyperbaric welding associated with other repair methods .

The fitting is available in structural and non-structural versions that provide pressure containment to the pipeline within the encapsulated area . The non-structural version may be used to repair a pipeline that is structurally sound and has only minor damage such as pinhole leaks, local pipe wall thinning or shallow dents . The structural version, utilizing a grip and bowl mechanism, replaces structural integrity in more severely damaged pipelines with cracked girth welds, kinks, or punctures .

After installation, the Smart Clamp design provides a permanent high quality seal with structural reinforcement extending for the design life of the pipeline .

Smart Clamp Design Features: Viton-B circumferential and longitudinal

seals as standard, Buna-N (Nitrile) or other elastomeric compounds can be provided for compatibility with pipeline contents or inhibitors

Elastomeric circumferential seals are mechanically set, permanently pressurized and fully restrained, mitigating concerns of explosive decompression effects for gas service

Port for annulus testing, grout injection or filling with inhibitor between the seals and pipeline

Galvalum III anodes sufficient for 25-yr design life

Externally coated with 3-part marine epoxy

Hardened steel grips and bowls (structural version) provide reinforcement to the pipeline by transferring axial loads from the pipeline into the body of the fitting, effectively replacing structural integrity and removing longitudinal stresses from the damaged pipeline section

Internal components are securely retained whether the fitting is open or closed, before or after installation


Smart Clamp - Diverless

Permanent Pipeline Repair ClampThe Diverless Smart Clamp is a split mechanical / hydraulic fitting used to repair a damaged or leaking subsea pipeline . The fitting eliminates costly pipeline shut downs and offers an alternative to hyperbaric welding repair methods .

The fitting, available in structural and non-structural versions, provides pressure containment to the pipeline within the encapsulated area . The non-structural version may be used to repair a pipeline that is structurally sound and has only minor damage such as pinhole leaks, local pipe wall thinning or shallow dents . The structural version, utilizing a grip and bowl mechanism, replaces structural integrity in more severely damaged pipelines with cracked girth welds, kinks, or punctures .

Diverless InstallationThe Diverless Smart Clamp is lowered into position just above the damaged pipeline section that has been lifted off the seabed using pipe lift frames . First, a Remotely Operated Vehicle (ROV) intervenes through a hot stab into one hydraulic coupling to pressurize the cylinders in order to open the clamp. The fitting is then lowered until the pipe saddles contact and position on the pipeline . An ROV utilizes the same dual port hot stab and hydraulic coupling to depressurize the cylinders to close the clamp . The body studs are then tightened using an ROV modified hydraulic torque wrench . The ROV intervenes through the second hydraulic coupling to simultaneously pressurize the actuator flanges and set the grip and seal mechanisms of the clamp . If the damaged pipeline section is not leaking, ROV again intervenes through the second dual port hydraulic coupling to perform an Annulus Test to verify the sealing integrity of the clamp . All the setting functions are hydraulic and are operated via an ROV panel with API 17D interfaces .


Smart Tap - Mechanical Hot Tap Fitting

Oceaneerings Smart Tap is a split mechanical hot tap fitting that provides a necessary flanged branch for hot tapping an existing subsea pipeline and tying-in a new lateral pipeline. The fitting eliminates costly pipeline shut downs and expensive hyperbaric welding .

Seal extrusion guards are for 12-in Nominal Pipe Size (NPS) and larger when API 5L pipe outside diameters tolerances become significant

Port for annulus testing between the seals and pipeline prior to tapping

Galvalum III anodes sufficient for 25-yr design life


RTJ flange lateral branch is standard, specialized flanges that accommodate temporary plugs for line stopping, scarfed nipples or pigging bars can be provided .

Hardened steel grips and bowls provide reinforcement to the pipeline by transferring axial loads from the pipeline into the body of the fitting, effectively replacing structural integrity after the branch hole is tapped

Internal components are securely retained whether the fitting is open or closed, before or after installation


Pressure-Balanced Breakaway Joint (PBBJ)

Oceaneerings Pressure-Balanced Breakaway Joint (PBBJ) is a connector that separates if an externally applied tension load exceeds a preset value . Separation of the PBBJ at the predetermined load is independent of the pipeline internal pressure or external water depth pressure .

The intentional separation of the joint prevents overloading and costly damage to structures to which the pipeline is attached as well as protecting the pipe itself . Structures such as platforms, risers, offshore tanker loading installations, subsea production systems and lateral pipeline tie-ins are protected from loads often caused by anchor drags, mud slides, iceberg scouring and violent sea states during hurricanes .

The PBBJ design features include: Completely factory assembled and tested

with preset separation loads up to the values tabulated

Separation load can be easily changed by an Oceaneering qualified technician anytime prior to installation without disassembly of any pressure containing component

May be refurbished by Oceaneering after separation

A split Locking Ring temporarily prevents installation loads from separating the PBBJ during pipe lay

Available with RTJ Flanged ends and with one or both Upstream and Downstream Check Valves

Dual Viton seals at each point of pressure containment



Electrical Isolation Joint (EIJ)

Piggable Wye Fitting

Oceaneerings Piggable Wye is a forged or cast fitting that joins pipelines and permits pigging from either inlet branch toward the single outlet. The fitting utilizes a 30 inclusive angle between the inlet bores, an industry accepted intersection for reliable passage of most common pipeline pigs .

The Piggable Wye is available in two

basic configurations, Symmetrical and Asymmetrical .

The inlets and outlets of the basic Piggable Wye terminate with a hub prepared for butt-welding

The ends can also be supplied with pipe pups for butt-welding or pipe pups with flanges

Oceaneerings Electrical Isolation Joint (EIJ) isolates the cathodic protection current in a pipeline from other sources that can act as current drains . These current draining sources such as power plants, equipment, steel reinforced concrete and other grounded structures must be isolated in order to achieve and maintain adequate, reliable and economical corrosion control . The EIJ is frequently used offshore to isolate the riser from the jacket structure where a potential difference exists between the two cathodic

protection systems . It may also be used to minimize galvanic action between pipelines of dissimilar metals .

The Monoblock style design of the EIJ is prefabricated, electrically tested and pressure tested at the factory . This type of design provides superior pressure containment and mechanical strength . Dual elastomeric seals are used to assure high quality long-term pressure integrity and mechanically, the EIJ is designed to be as strong as the pipeline .

Hydraulic Smart Flange (HSF) Connector

For deepwater pipeline and riser repairs, Oceaneering PCRS offers a hydraulically-set pipe end connector based on the proven technology of the Smart Flange Plus Connector . The connector is designed to provide a structural connection point subsea . When actuated, the Hydraulic Smart Flange (HSF) Connector will structurally attach to and seal against the pipe . Its capable of withstanding full pipeline axial, bending, and torsional loads while maintaining full line pressure integrity .

The HSF may be provisioned with a Grayloc male hub, a flange, or may be connected with another HSF in a double arrangement, making it a double grip and seal type connector .

The ROV uses a single hot stab to pressurize the port in the connector in order to set the gripping and sealing mechanisms on the pipe . The HSF has dual setting pistons . During

the initial setting of the connector, the seal piston is driven axially to set the main and test seals around the pipe . The pressure is then increased to drive the slip piston axially in the opposite direction from the seal piston to set the gripping mechanism on the pipe . Both pistons are locked into final position by a series of spring-energized ratcheting locking mechanisms positioned radially inside the connector housing . These locking devices ensure a positive lock preventing any possible back driving . An annulus test port feature allows the sealing integrity to be confirmed by pressurizing the annulus between the main and test seals .

Hydraulic Smart Flange (HSF) Connectors can be designed in sizes and pressure ratings to meet any customer requirements . The connectors are available in configurations with other connectors and fittings.
