system after setting and installation of the HydroCouple. This is accomplished fay pressuring the annulus space be­tween the two packing stacks. The diver attaches a hydrau­l i c hose from the surface support ship to the annulus test port. Pressurization of the annulus is then carried out from a test unit on the surface where the pressure can be monitored directly by the installation supervisor.

When the pipeline operating temperature is unusually high compared to the temperature of the seawater, i t may be nec­essary to provide the HydroCouple with a temperature compen­sated sealing system. This patented mechanism regulates the pressure fluctuations in the rubber packers to a band width that w i l l neither damage the pipe due to excessive pressure or result in seal failure due to loss of sealing pressure. In most cases the HydroCouple and pipe are sufficiently e l a s t i c to self compensate for seal expansion and contrac­tion due to temperature fluctuations.

One of the great advantages of the HydroCouple as a pipe­line connector is the minimal amount of pipe end prepara­tion required for successful installation. The HydroCouple Is designed to stab over a subsea pipeline which has been cut-off by a diver using no more than a standard underwater burning torch. Concrete weight coating, if present, must also be removed from the pipe as well as any other coating such as somastic and coal tar enamel. Thin film epoxy coat­ings i f no more than 0.010-0.015 inches thick, do not re­quire complete removal. Complete removal of the longitudi­nal weld seam to blend with the pipe contour is not required, however, some grinding to flatten the crown of the weld bead is advised.

HydroCouples are available in sizes and pressure ratings ranging from 3 inch - API 10000 psi to 48 inch - ANSI 600 Class. Almost any variation of pressure rating as well as hydraulic or mechanical actuation is available within the size range. In addition the HydroCouple is available in configurations in combination with other connectors and fit t i n g s . Several optional configurations are described in Section VI of this specification.

I I . HYDRAULIC -SET OPTION (Mark IV)

The hydraulic s-et version of the basic HydroCouple connec­tor is referred to as the Mark IV HydroCouple. See attached drawing SK 1691. The Mark IV HydroCouple contains two (2) independent hydraulic c i r c u i t s - one for setting the s l i p s and one for setting the seals. The hydraulic set (Mark IV)

GENERAL PRODUCT SPECIFICATION

HYDROCOUPLE PIPELINE CONNECTOR

I . GENERAL DESCRIPTION

The HydroCouple connector is a sleeve type pipeline connec­tor designed to stab over an un-coated pipe, and when mech­anically or hydraulically actuated, structurally attaches to and seals off the pipe. The HydroCouple concept was devel­oped in 1966 to f a c i l i t a t e sub-sea pipeline connections made by divers working under adverse conditions. When properly installed, the HydroCouple can be used to permanently con­nect high pressure pipelines and ri s e r s for both underwater repair and new construction applications. Over 800 Hydro­Couple connectors have been manufactured and tested and over 500 installed. Numerous HydroCouples have been in continu­ous service successfully for over 15 years.

The HydroCouple connector structurally attaches to the pipe­line or r i s e r using two sets of opposed wedge-shaped " s l i p " segments positioned circumferentially inside the Hydro­Couple body. The s l i p segments are wedged between hydraulic actuators. Due to the wedge angle and other design factors the sli p s are self-locking, i.e., the higher the tension or compression force, the tighter they grip the pipeline. One of the opposing s l i p s is designed to support tension loads due to the thrust effects of internal pressure and any ex­ternally applied loads. The other set of opposing sli p s is designed to support compression loads resulting from pipe­line thermal expansion or other loads of a compressive nature.

The HydroCouple sealing system consists of two stacks of elastomer packers. These packers are compressed in an axial direction using the hydraulic or mechanical actuation sys­tem. When axially compressed the rubber packers flow radial­ly inward against the pipe OD and outwardly against the HydroCouple body. The sealing pressure of the HydroCouple is determined by the axial force applied to the packing stack and the resulting radial force exerted by the rubber against the pipe and HydroCouple body. The seal system is backed-up at the extremities of each packing stack by metal guard rings which prevent rubber extrusion into the gap be­tween the HydroCouple and the pipe OD surface. A pressure test feature is provided for the verification of the sealing

option is considered to have an advantage for large diameter pipelines in deep water due to the reduction of diver time required to set the slip s and seals. The hydraulic set option also has the capability of being modified for diver­less installation.

.The hydraulic setting of slip s and seals has been made in­dependent so that the seals' may be set f i r s t and then tested via the annulus test feature. I f the seals have failed to set properly the installation supervisor has the option of removing the HydroCouple from the pipe followed by recovery to the surface where a detailed analysis of the problem can be made. When the seals have been properly set and tested in a normal installation, the slips may then set after which the HydroCouple cannot be removed from the pipe.

The Mark IV HydroCouple is hydraulically set using catalyzed epoxy for the hydraulic fluid. The liquid epoxy i s injected into the hydraulic c i r c u i t from an epoxy f i l l e d applicator connected to the HydroCouple by a short high pressure hose. The applicator is operated by conventional hydraulic fluid supplied from the high pressure unit on the surface support vessel. The epoxy is specially formulated to harden in 6-12 hours; more than enough time to set and test the seals. When solidified the epoxy effectively and permanently locks the seals and s l i p s . The Mark IV seals may be re-energized i f necessary by simply tightening the nuts holding and packing flange in place.

I I I . MECHANICAL SET OPTION (Mark V)

The mechanical set version of the basic HydroCouple connec­tor is referred to as the Mark V HydroCouple. See attached Drawing SK 1692. The Mark V HydroCouple is the ultimate in simplicity and yet contains the basic opposed tension and compression slips and dual seals with annulus test capabil­ity. The Mark V s l i p s and seals are simultaneously set by a diver tightening the nuts holding the packing flange to the HydroCouple body to a prescribed torque value using a simple hand operated torque wrench. When set the seals can be tested from the surface support vessel by connecting a hy­draulic hose to the annulus test port. I f the seals are not properly set or the other d i f f i c u l t i e s arise, the Hydro­Couple may be removed from the pipeline and recovered to the surface by f i r s t removing the packing flange and loosening the grip of. the s l i p ton the pipe. The seals may be re­energized if necessary by simply tightening the packing flange nuts.

VI. OPTIONAL CONFIGURATIONS

A. Spool Piece Repair Unit (SPRU)

The Spool Piece Repair Unit consists of the basic Hydro­Couple connector with an Extension Nipple and a Misalign­ment Flange (MAF). The MAF is described in a separate General Product Specification. The HydroCouple is welded to the MAF Housing. The mating Ball with Retainer Flange of the MAF has a welding end compatible with the mating pipe dia­meter and wall thickness. An illustration of a Mark V SPRU is shown in Drawing 1349. The Extension Nipple and MAF Housing inside diameter is the same as the HydroCouple I.D. The purpose of this configuration is to provide a capability to adjust the axial position of the HydroCouple on the pipe­line end and therefore, reduce the c r i t i c a l i t y of the spool piece length measurement. The axial adjustment provided by the Extension Nipple is 1 pipe diameter or 12 inches which­ever is greater. A spool piece repair requires 2 SPRU's.

Riser Connection Unit (RCU)

B. The Riser Connection Unit also consists of the basic Hydro­Couple connector with Extension Nipple and Misalignment Flange. The HydroCouple is welded to the Extension Nipple with transition adapter which is welded to an MAF Ball with Retainer Flange. The mating MAF Housing has a butt welding end equal to the pipe diameter and wall thickness and is welded to the r i s e r pre installed on the platform jacket be­fore launching. An illustration of a Mark V RCU is shown in Drawing SK 1683. As with the SPRU the Extension Nipple pro­vides axial movement of the HydroCouple on the pipe end of up to 1 pipe of diameter or 12 inches whichever is greater. While the RCU is normally used to make pipeline to r i s e r t i e - i n s , the RCU can also be used to make a spool piece re­pair. Two RCU's are required to make a spool piece repair.

C. Riser Repair Unit (RRU)

The RRU consists of the basic HydroCouple connector without compression s l i p s . A Mark V RRU * is shown in Drawing SK 1689. The r i s e r pipe stabs into the body of the RRU until it rests against the shoulder in the RRU body. Any compression loads are then transmitted directly to the RRU body. The RRU has a welding end configuration that matches the nominal pipe diameter and wall thickness. The body of the RRU can be specified to have a minimum yield strength at the welding end of 52,000 psi.

0. Pipeline End Connector

HydroTech Sysleir A Company

In some cases underwater pipeline and r i s e r repairs can be made ef f i c i e n t l y and economically by simply using the Riser Repair Unit in combination with RTJ Flange or MAF butt weld­ed to the end as illustrated in the attached Drawings SK 1682 and 1684. In this case the HydroCouple is being used only for the purpose of attaching a flange to the end of a subsea pipeline without l i f t i n g the pipeline above water and welding or making a hyperbaric weld. In this configuration the HydroCouple connector provides no end gap compensation.
