Introduction

A vision of connector technology for the future

By combining its experience in fabricating

onshore and subsea pipelines and riser

systems with polymer materials technology

and fusion welding, Swagelining Limited

(SWL) has developed a genuinely novel

connector system for joining polymer lined

carbon steel stalks together.

The LinerBridge® Connection System is a step

change in weldable connector technology for

polymer lined pipelines and risers. The vision

driving the connection system development is

to make it easier to build and install polymer

lined pipelines. The LinerBridge® Connection

System comprises a number of components

that can be flexibly interchanged to suite

the pipeline architecture and construction

strategy.

The LinerBridge® Connection System is

designed to:-

• Reduce the cost of lined pipelines

• Reduce risk in fabrication and installation

of lined pipelines

• Eliminate (or reduce) corrosion resistant

alloy materials from system hardware

• Enable lined pipelines and risers to be

cut to length offshore and terminated

efficiently

• Facilitate the repair and / or replacement

of damaged sections of lined pipelines

• Make it possible to tie in additional facilities

to existing lined pipelines

New thinking delivers improvements

When compared to the existing weldable

connectors made using corrosion resistant

alloy materials, the LinerBridge® Connection

System is a revolution in connector

technology. There are three significant

differentiators underpinning the step change

from existing connector architecture:-

1. It’s made from polymer, not steel or alloy

The LinerBridge® Connector is made from

the same polymer material as the liner. It is

joined to the liner internally by fusion welding.

The result is a continuous polymer liner along

the pipeline length. Through the careful use

of insulation and heat shielding materials,

carbon steel girth welds can be made over

the LinerBridge® Connector using standard

pipeline welding processes. No purging or

specialist CRA weld operations required.

Introduction

2. To start with, finish the ends

Polymer lined end termination fittings are

completed onshore in SWL Development

Centre and shipped to site as completed

components. These are then welded to the

polymer lined pipeline as ‘pipe to pipe’ carbon

steel welds at site using the LinerBridge®

connector.

3. Any type of end termination fitting now possible

End termination flexibility for polymer lined

pipelines just got much easier. Flanged end

connections or welded end connections are

now possible. If the end connection is a Clad

or CRA fitting, SWL will line it for fitting /

welding to the end termination facility (PLET,

PLEM, Tee etc.) before the lined pipeline

is tied in. The field Tie In is now a carbon

steel ‘pipe to pipe’ weld made over the

LinerBridge® Connector.

Onshore and offshore use

The LinerBridge® connector is suitable for

onshore and offshore use. The connector

can be welded in 2G (J-Lay), 5G (S-Lay and

onshore tie ins) and 6G (Reel-lay) positions.

Bespoke s-lay and j-lay package is in

development aimed at facilitating laybarges

to install polymer lined pipelines cost

effectively through the vessel firing line. Single

(or double or quad or hex) polymer lined

carbon steel joints will be lined and connected

by welding using LinerBridge® connectors.

This option is expected to present a cost

effective alternative development option

when compared to the cost of CRA derived

pipelines.

Pre-Qualification Test Status

The LinerBridge® Connector is undergoing a

range of PQT activities as part of the drive to

qualify the system. These include fabrication

trials, reeling trials and hydrotesting of reeled

and non-reeled test strings. All testing to date

has been completed in cooperation with a

number of global EPC pipeline contractors.

Testing has been undertaken at TWI and

Heriot Watt University. Hydrotest pressures

have been undertaken at 340 bar (5000psi).

The LinerBridge® is a registered trademark.

The LinerBridge® Connector is protected

by a range of patents and pending patents

globally.
