5. PROTECTION, HANDLING AND SHIPMENT
Siemens Subsea electrical connectors are manufactured primarily from materials such as 316L
stainless steel (UNS S31603), and Super Duplex stainless steel (UNS S32550). Stainless steel 316L
(UNS S31603) connectors and penetrators must be connected to a CP (Cathodic Protection) system
at all times in order to withstand harsh saliferous
environments. Super Duplex stainless steel (UNS
S32550) connectors and penetrators have no need to be connected to a CP system in order to
withstand harsh saliferous
environments. Siemens recommends that such connectors and
penetrators are not connected to a CP system in order to avoid the risk of introducing HISC (Hydrogen
Induced Stress Cracking).
The connector insert and exposed parts are susceptible to mechanical damage if not adequately
protected. Dust caps are fitted to all Siemens Subsea connectors before transport, but can be fitted
with protective caps if specified by the customer. Caps are recommended to remain in place until
connectors are deployed subsea.
The connectors can be shipped singularly or in multiples. Care should be taken to protect the
connector with bubble wrap or similar wrapping materials to avoid surface damage during transit. If
large numbers are shipped in one consignment a suitably reinforced box will be necessary to withstand
the weight. Protection caps must be fitted at all times during transport.
If storage is carried out in saline conditions, e.g. on a
ship’s deck or hold, then full dummy connectors
should be used.
Bulkhead type connectors with exposed tailing wires should be packed and shipped in a suitably sized
box to allow adequate space for the tailing wires without bending or kinking.
If the connectors are assembled onto hoses these must be suitably coiled and secured with tape to
prevent uncoiling during transit. The following bend radii are recommended for storage/transport of
hoses.
•
Gorilla 1
.5” NB – (Static) Minimum Bend Radii – 250mm
•
AquaTRON 2” NB (AquaTRON 200) – Minimum Bend Radii - 375mm
Connectors are designed to withstand vibration that occurs during transportation and to withstand
being dropped from a height of 1m whilst in packaging.
Figure 3 shows how a SpecTRON 5 harness is packaged. The connectors on either end of the harness
have a transportation cap fitted and are surrounded in bubble wrap. The base of the shipping crate is
lined with protective packaging and the harness is positioned so that the hose can be coiled without
kinking. Any loose items are placed in a box inside the crate. Protective packaging is then placed on
top of the harness and secured in place with a wooden baton, before the lid of the crate is screwed
down.
