Seal assembly and method of testing

A method of testing dual seals of a subsea termination, the method comprising:

• assembling a sleeve to a first termination body and to a first part of a second termination body;
• providing primary and secondary seals between the first body and the sleeve and between the second body and the sleeve to form a chamber between the two bodies;
• generating a pressure difference between a point located between the primary and secondary seals of the first termination body and a point located the other side of either of the primary and secondary seals;
• and
• detecting whether or not test fluid has passed through either of the primary and secondary seals.

A method of testing dual seals of a subsea termination, the method comprising:

• providing primary and secondary seals on a first termination body;
• assembling a sleeve to the first termination body such that the seals are between the sleeve and the first termination body;
• supplying test fluid through a test port to a point between the primary and secondary seals of the first termination body, such that a pressure difference is created between the point and the other side of the primary seal and the other side of the secondary seal;
• and
• detecting whether or not test fluid has passed through either of the primary and secondary seals.
