Connector arrangement for a subsea pipeline

A barrier connector arrangement for a multi-pipe pipeline for use in a subsea environment, the pipeline comprising an inner pipe and an outer pipe around the inner pipe to define a dry annulus between the inner pipe and the outer pipe, and at least one cable extending along the annulus, the connector arrangement comprising:

• an outer housing configured to be joined to the outer pipe to define a dry interior around the outer pipe in communication with the annulus;
• and
• at least one dry barrier chamber with a dry interior, the at least one dry barrier chamber extending partially through the outer housing, and having one end located inside of the outer housing, another, opposite end located outside of the outer housing and a portion surrounding the dry interior of the at least one dry barrier chamber, located between the one end and the another end and welded to the outer housing, the at least one dry barrier chamber being configured to receive at least one wet mateable penetrator at the another end thereof to keep the interior of the at least one dry barrier chamber dry and to connect the at least one cable in the pipeline with at least one external cable in the subsea environment.
