16. PROTECTION, HANDLING AND SHIPMENT (INCLUDING FROM CUSTOMERS) Siemens Subsea connectors are manufactured primarily from materials such as 316L stainless steel (UNS S31603), and Super Duplex stainless steel (UNS S32550), and as such are designed to withstand harsh saliferous environments. However, the connector insert and exposed parts are susceptible to mechanical damage if not adequately protected. -

IOM-007 Installation Operation Manual for TC3A-107 and Similar EDUs If storage is carried out in saline conditions, e.g. on a ship’s deck or hold, then full dummy connectors should be used. The junction box must be secured in a dedictaed transit box and always remain in a horizontal position to prevent risk of damage to the diaphragms. -

IOM-007 Installation Operation Manual for TC3A-107 and Similar EDUs No carbon steel must be present in the storage of the products. Please note; maximum storage temperature takes into account solar gain. Skin temperature must not exceed 70°C. Suitable protection must be used to ensure maximum storage temperature is not exceeded. -

IOM-007 Installation Operation Manual for TC3A-107 and Similar EDUs Stainless steel 316L (UNS S31603) diver mate connectors must be connected to the CP (Cathodic Protection) system at all times. Super Duplex stainless steel (UNS S32550) connectors should be isolated from the CP system to reduce the possibility of hydrogen embrittlement. - Page 9 IOM-007 Installation Operation Manual for TC3A-107 and Similar EDUs Figure 1 (ref) – Indicates distance of 604.50mm for mounting interface hole positions (tol. +/- 0.25mm) Figure 2 (ref) – Indicates distance of 182.00mm for mounting interface hole positions (tol. +/- 0.25mm) 2.

IOM-007 Installation Operation Manual for TC3A-107 and Similar EDUs 11.2 Live Mate / De-mate Resistive loads Mating the connectors should not lead to any damage to the sealing mechanisms within the plugs. The speed of de-mating should be between 40mm/s to 60mm/s. Following this de-mating procedure, testing should be carried out on the connector to establish if any damage has occurred. - Page 14 IOM-007 Installation Operation Manual for TC3A-107 and Similar EDUs Figure 9 – EFL Schematic Mating • The clamp ring should be rotated clockwise by hand until tight.
