jumpers in this example the mandrel 172 comprises a central pipe 174 having end hubs 176 178 for connection with the subsea test tree 26 and the landing string pipe 168 respectively in this instance the insulation 212 can be secured to extend about and along the pipe 174 to be integrated with the subsea control module 170 as shown in fig1 one embodiment of the subsea control assembly 164 is further illustrated in fig1 in this embodiment the subsea control module 170 is mounted around mandrel 172 and comprises a plurality of sections 180 the sections 180 may be integrally formed and mounted around mandrel 172 or the sections 180 may be individually slid over mandrel 172 locked to the mandrel and coupled to each other as necessary for example hydraulic and electrical connections may be formed with hydraulic and electrical jumpers between the plurality of sections 180 in the particular example illustrated the plurality of sections 180 forming subsea control module 170 comprises an upper section having at least one accumulator e g accumulator 88 a hydrostatic pressure temperature compensator 182 e g volume compensator and a subsea electronics module 184 the upper section 180 is coupled to a lower section comprising a hydraulic valve manifold pod 186 by way of example the at least one accumulator 88 may comprise a plurality of the accumulators such as the five pressure balance accumulators illustrated as deployed around mandrel 172 depending on the application the accumulators may be used to store hydraulic fluid.
