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 / UNS S32760) ROV connectors may be isolated from the CP system to
reduce the possibility of hydrogen embrittlement and calcareous deposits. ROV Connectors are
designed with isolation bushes and discs in order to isolate them from the structure as standard.
Tree Cap Plugs, Tubing Hanger Rece ptacles and Penetrators cannot be isolated from the structure
and thus m ay be connected to the CP system.

The connector insert and exposed parts are susceptible to mechanical damage if not adequately
protected. Dust caps or Protective caps are fitted to all Siemens Subsea connectors before
transport. 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 weigh t. Protection caps must be fitted at all times duri ng transport.

NOTE: Maximu m storage temperature takes in to account sol ar gain. Skin temperature must
not exceed 700C. Suitab le pro tection i . e. a tarp aulin or mat erial wit h si milar p roperti es mu st be
used to ensure maximum storage temperature is not exceeded.

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 witho ut 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
hose.

• AquaTRON 2” NB (AquaTRON 200) - Minimum bend radii - 375mm

• AquaTRON 0.5” NB (AquaTRON 50) - Minimum bend radii - 125mm

Connectors are designed to withstand vibration that occurs during transportation and to withstand
being dr opped from a height of 1m whilst in packaging.
Figure 3 shows how a SpecTRON 8 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.

5.1 LIFTING OF JUMPERS & CONNECTORS

SpecTRON 8 harnesses typically weigh in excess of 30 kg and hence should not be manually
handled. Refer to the specific harness drawing for weight and length details. The connectors can
be safely slung around the locations shown in, Figure , Figure , Figure and Figure 7. The centre
of gravity for the Connector or Penetrator is usually marked on the outline drawing (supplied in
documentation pack) but must be verified at low level before commencing any lift.

Note: Ensure that all coated components are handled with care during lifting to avoid damaging
the coating.

6. UNPACKING

Remove wrapping material taking care to inspect for any surface damage or items that may have
become separated from the connector, such as ‘O' seals. Do not use a knife to cut the wrapping
material, as this may cause damage to any elastomeric parts of the connector. Do not remove
protection caps until connectors are ready for installation. On removal do not allow the hoses to
drag over the edges of the packing crate.

6.1 PROTECTIVE CAPS

All SpecTRON 8 Connectors/Penetrators come supplied with a protective cap. These can either be
dust caps or protective caps. Dust caps (typically yellow in colour) can be simply removed by
twisting or pulling them off. Protective caps (typically black in colour) can be removed as detailed
below.

6.1.1 ROV Plug Cap

The ROV Plug cap is latched onto the Plug connector via the connector latching mechanism. In
order to remove the cap, it is recommended that the operator stand the Plug vertically on the cap,
stand on the flange of the cap and pull on the ROV handle of the Plug connector. This will
disengage the latching mechanism of the Plug. Do not try to pull the cap directly off the plug as this
may damage the latching mechanism of the Plug. Use the same method when engaging and
disengaging the ROV plug cap on the Plug connectors with the locking mechanism.

7. STORAGE

The connectors must be stored in a clean dry area and be protected by bubble wrap or similar.
Suitable protection caps must be fitted and the storage temperature should be between -30°C and
60°C (Project Specific Connectors storage Temperature may vary). Humidity of the store room
should be below 75%. Very moist or very dry conditions should be avoided. The Plug connector
and hoses should be protected from strong sunlight and strong artificial light with a high ultra violet
content. The connectors should not be allowed to come into contact with solvents, oil, greases or
any other semi-solid materials. If glanded connectors are to be stored bolted into their interfaces
prior to cable termination, then ensure the cable entry point into the gland is covered to prevent
water ingress.

8. DEPLOYMENT & MAINT ENANCE

The following section details deployment and maintenance instructions for SpecTRON 8
connectors & hose.

All information contained within this section is generic. Where customer or project-specific
information is required, please refer to the relevant project specification or scope of supply.

NOTE: IT IS IMPORTANT TO ISOLATE AND EARTH PRIOR TO DISCONNECT IN ORDER TO
REMOVE ANY STRAY CHARGES IN THE SYSTEM. IF LEFT, THIS CAN INDUCE CORROSION ON
THE EXPOSED PINS ONCE THE PLUG IS REMOVED.

8.1 GENERAL

The SpecTRON 8 range of Power connectors has been developed for long term reliable high
power system applications associated with offshore installations. The underwater mateable
capacity of these connectors is achieved using pressure compensated electrical inserts employing
the CE principl e.

Connectors are usually supplied with protective caps. The protective caps must be removed prior
to mating the connectors. Refer to section 6.1 for instructions for removal of protective caps.

All mild steel sealing interfaces shall be inlayed with Inconel 625, or similar, where no additional
protection (e.g. CP, Paint etc.) can be provided. This is to prevent localise d pitting of the interface.

If the connectors are to be left unmated, in seawater, for any length of time dummy connectors
must be used to protect the pin contacts in the receptacle connectors. Over exposure will increase
the risk of corrosion damage or marine growth on the contact surfaces of the receptacle contact
pins. This could lead to damage to the seals and insulation within the socket contacts.

Plug connectors may be left unmated, in seawater, for an indefinite period of time. However it is
recommended that the Plug connectors are mated into a Parking Receptacle during this time in
order to protect the socket contacts and latching mechanism.
It is good practice to always fit the protective cap when a connector is unmated topside prior to
deployment to provide mechanical protection.

The appropriate test connector must always be used to make electrical contact during testing.
UNDER NO CIRCUMSTANCES should a foreign object (such as a screwdriver, test probe, or
crocodile clip) be used as a test connection as this could damage the seals and insulation. Such
actions will invalidate the warranty of the connector.

Guide pins must never be removed from test connectors as this can lead to damage and will
invalidate the connector warranty.

NEITHER SHOULD CONNECTORS BE PARTIALLY MATED WITH POWER APPLIED.

8.2 PROTECTION OF RECEPTACLE CONTACT PINS

Under no circumstances must the contact pins in the receptacle connector be exposed to seawater
with power on. If this situation does occur the contact surfaces of the pins will very rapidly degrade
by electrolytic action. If these damaged pins are subsequently mated into a socket insert there is a
very high risk of damage to t he insulation and seals wi thin the plug connector.

8.3 OVER CURRENT CAPACITY

Over curr ent capacity varies for each product. Ple ase refer to the product datasheet.

8.4 REMOVAL OF MARINE GROWTH AND CALCAREOUS DEPOSITS

To remove calcite growth from Siemens Subsea connectors, a solution of 50% Citric Acid is
recommended. All Seawater exposed elastomeric materials in Siemens Subsea connectors have
been fully tested against 50% Citric Acid and are compatible for duration of 1 hour. In addition, the
thermoplastic materials have good resistance to Citric Acid.
It is recommended the solution is introduced through the flushing port adaptor (as per Figure 15)
to provide maximum saturation within the Plug/Receptacle annulus. Others cavities on the
receptacle shroud can be utilised to introduce the solution dependan t on access capabil ity.

Other acid cleaners, such as 50% Acetic Acid, should not be used as they may cause deterioration
of the elastomeric materials.

Chiselling and abrasive methods are not recommended. Wiping with a soft, clean cloth is
acceptable providing care is taken inside the Receptacle shroud to avoid imparting a bending load
on the power pin/s. Use of water jetting for the removal of sand/silt is acceptable given the
following limita tions:

• All forms of water jet cleaning of connectors in air must be avoided. The likelihood of
damage to connectors is great, given the high localised impact velocities of the water jet.

• Submerged water jet cleaning of connectors is acceptable, providing the critical areas
identified in Figure 14 & Figure 15 are avoided. Particularly, the jet should not be directed
at the Plug front face / shuttle pins as this could result in a risk of water being forced
through the primary seals and/or front seal. Remaining areas indicated below are suitable
for submerged water jet cleaning.

8.5 STAB PLATE CONNECTORS

Compliance

One half of a stab mate connector pair must be allowed to float so that misalignment tolerances
can be accommodated.

Mate/De-Mate Speed

The connectors have been designed to operate across a wide range of mate / de-mate speeds
with POWER OFF. There is no practical limit to the speed at which the connectors maybe mated or
de-mated, however as a guide:

Mating speed should not exceed 1 m/s .
De-mating speed should not exceed 5 m/s

Pre-Mating Checks

Before mating, the receptacle connector should be checked for debris. The connectors have been
designed to accommodate sand and silt contamination; however large pieces of debris should be
removed using a water jet.

Partial Disconnection

Partial disconnection with the contact pin remaining between the primary and secondary
diaphragms is not recommended. In this condition the level of insulation between the contact pin
and socket contact is reduced and the connector is relying on the primary seals within the plug.
There is also an increased risk of insulation break down at increased voltages.

Interrupted Connection

Interrupted connection (i.e. Partial mate to full de-mate) can be carried out without any adverse
affect to connectors, as long as the power is off.

Cathodic Protection:

Stainless steel 316L (UNS S31603) connectors must be connected to the CP (Cathodic Protection)
system at all times. Super Duplex stainless steel (UNS S32550 / UNS S32760) connectors may be
isolated from the CP system through the design of the structure to which they are connected to
reduce the possibility of hydrogen embrittlement and calcareous deposits. However, it should be
noted that Tree Cap Plugs, Tubing Hanger Receptacles and Penetrators cannot be isolated from
the structure as they do not utilise isolation discs and bushes due to their mechanical and pressure
retaining requirements.

8.6 ROV CONNECTORS

ROV Manipulator

SpecTRON 8 connectors are fitted with either an ISO 13628 T-bar handle or an ISO 13628 Fish
Tail Handle.

T Bar Handle

T-bar handle connectors must be manipulated using a Parallel Jaw ROV manipulator similar to that
shown in Figure 16.

Figure 46 – Recommended ROV Manipulator Jaw for T Bar Handle

The T bar should be held by the crossbar of the T as shown in Figure 17Error! Reference source
not found. and not by the shaft. If the T bar is held incorrectly there is a risk that the latch

mechanism of the connector will not engage correctly.

9. ROV MATE / DE-MATE PROCEDURES

9.1 ROV MATING PROCEDURE

Pre Mating Checks

Before mating, the receptacle shroud should be checked for debris. The connectors have been
designed to accommodate sand and silt contamination. However, large pieces of debris should be
removed.

9.2 Alignment and Mating Procedure – Connectors without Locking Mechanism

• The connectors have been designed to self align during mating, however they must be roughly
aligned using the alignment marks on the top of the Connector body & Alignment flange /
Receptacle shroud prior to mating. (Figure 20A & 20B).

• Note the location of the alignment key/keyway on the underside of the Connectors. (Figure
20A820 & 20B ).

• Compliance is built into the connector handle, and the receptacle mount. This flexibility
accommodates misalignment and allows fine adjustments during the final approach prior to
connect or en ga gem ent.

• The mating stroke should be as close as possible to one smooth movement, i.e. avoid
‘pumping’. Using the ROV manipulator jaw, the pilot should grip the ROV handle as shown in
Figure 17 or Figure 19.

• The internal latch mechanism is activated by pushing the connectors together until the f langes
of the plug and receptacle are fully home (Figure 22).

• To ensure correct engagement, the ROV pilot should open the jaw and operate a final push
operation before withdrawing from the T bar with a fully open jaw (Figure 21). This ensures
that the internal latch mechanism is not accidentally disengaged as the ROV pulls away from
the connector.

• As dictated by Industry best practice, all ROV operations are to be recorded on video. The
video is to be retained and made available to Siemens Subsea as and when required.

Post-Mating checks:

• Correct mating of the connector must be determined by visual inspection only (Figure 22).

• The shoulder on the Plug should butt up against the shroud of the Receptacle. Note: when

relaxed there may be a small gap between the two (due to the springs in the Plug pushing
against t he Receptacle pins).

• Important: A pull-check on the handle should never be made as this will release the internal
latching mechanism causing the connectors to separate.

9.4 ROV DE-MATING PROCEDURE

9.5 De-Mating Procedure - Connectors without Locking Mechanism

• To De-mate the connector, Grip the ROV handle (T-handle or f ishtail) correctly with the ROV
jaw (Figure 57 or Figure 79)

• De-mating is achieved by a straight pull on the ROV handle sufficient to release the internal
latching mechanism. Do not pull on the gland or hose.

Note: If the ROV handle is held incorrectly there is a risk that the internal latch mechanism of
the connector will not disengage properly

9.6 De-Mating procedure - Connectors with Locking Mechanism

• Before De-mating the connector the ROV pilot must first release the locking mechanism.

• The locking mechanism is released by pushing forward the release paddle using the nose of

the ROV manipulator jaw. (Figure 26)

• The locks will disengage from the receptacle pins when the paddle is pushed fully forward.
(Figure 146)

• When this action has been performed correctly the release paddle will remain in the forward
position after the ROV jaw is retracted.

• Figure 146 Detail view shows the locks in the disengaged position.

• To De-mate the connector, Grip the ROV handle (T-handle or fishtail) correctly with the ROV

jaw (Figure 57 or Figure 79).

• De-mating is achieved by a pull on the ROV handle sufficient to release the internal latching
mechanism. Do not pull on the gland or hose.

• As the connector is de-mated the release paddle will automatically return to the default
position. No ROV pilot action is required.

• On de-mating, the locking mechanism re-sets automatically and can be immediately re-mated
if required. No ROV pilot action is required prior to re-mating.

Note: If the ROV handle is held incorrectly there is a risk that the internal latch mechanism of the
connector will not disengage properly.

.

Manual Mating / De-Mating of ROV connectors

Refer to Section 10 for manual Mating / De-mating procedure.

Cathodic Protection

The ROV connectors are designed to operate when isolated from the CP [Cathodic Protection]
system. The ROV connectors will not suffer damage by being connected to the CP system;
however there may be a tendency for increased calcareous deposits on metal surfaces, and the
possibility of hydrogen embrittlement.

9.7 Emergency De-mate Procedure – Connectors with Locking Mechanism Only

The emergency De-mate procedure is to be used in the event of a malfunction or failure of the
locking mechanism which is preventing normal operation.

• To De-mate the connector Grip the T-handle or fishtail handle correctly with the ROV jaw
(Figure 5 or Figure 19).

• De-mating is achieved by pulling on the ROV handle (Do not pull on the gland or hose). A pull
force of 3 to 4kN is required to break the internal shear pins and release the mechanism
allowing the connector to de-mate.

Not e: Following an emergency de-mate the connector is still functional and can be safely re-mated
if required. Co ntinued operation is possible due to the internal latches which remain fully fu nctional.

The locking mechanism will be inoperable following the emergency release and the connector
must be recovered to the surface in order to repair the mechanism.

10. MANU AL MAT E/ DE-M ATE PROCEDURES

This section summarises the procedure to be followed for a diver or topside operator to mate/de­mate the ROV connectors manually (as opposed to mating/de-mating using an ROV).

10.1 MANUAL MATING PROCEDURE

10.2 Alignment and Mating Procedure – Connectors without Locking Mechanism

Prior to commencing the mating of the connector pair it is assumed that the Receptacle connector
is mounted to its associated mounting plate, and that the Plug connector is in the near vicinity.
Grab bars or other interfaces should be present on the Receptacle mounting structure. These
should provide the diver with purchase and allow him to address the connector square-on with the
connector at chest height.

• Remove protective cap from Plug connector, or if Plug connector is mated to a
Parking/Dummy Receptacle remove as detailed in the manual de-mating procedure below.

• If a Dummy Plug connector is mated to the Receptacle, remove using the manual de-mating
procedure detailed below.

• Inspect the Receptacle pins and shroud, and ensure they are clean and free from debris, etc.
If any debris is present remove using a water jet. Note: This operation must not be performed
in air.

• Insert the Plug Connector nose into the shroud of the Receptacle, and initially locate the key
on the Plug nose into the slot of the Receptacle shroud using the alignment indicators, as
shown in Figure 20A820A and 20B. It should be noted that the physical key/keyway are
located on the under side of the connect ors.

• The operator should now get into a comfortable position, square on, ready to fully mate the
connectors. The connector should be at chest height, with the grab bars or other provided
interfaces on the mounting structure being within easy reach. Using the grab bars or other
means to brace himself (i.e. tied to structure), the operator should mate the connector by
holding the ROV handle (Figure 28) and using one smooth single stroke to push the Plug
connector until it butts up against the Receptacle. A maximum f orce of 76.5kgf (750N) will be
required to mate the connectors. Ensure the mating stroke is level, and the operator is able to
complete the stroke in one smooth consistent movement. Confirm that no bounce-back and
failure to latch hom e has occurred.

WARNING: DO NOT PULL ON THE ROV HANDLE TO CHECK THE CONNECTOR IS CORRECTLY
MATED AS THIS WILL DISENGAGE THE INTERNAL LATCH MECHANISM AND DE-MATE THE
CONNECTOR

• When the plug connector end stops abut to the receptacle this activates the internal spring
loaded internal latch mechanism, which prevents the connectors de-mating. Pulling on the
ROV Handle will de-activate this latch and hence will de-mate the connector.

Figure 28 - Mate using ROV Handle

• To confirm that connectors are fully mated and the Plug is correctly latched home, gently pull
the Plug connector by holding the angled downward section of the Plug gland near to the hose
termination, as shown in Figure 159. If the connectors are correctly latched and mated no
axial movement in the Plug connector should be present. As a visual inspection, the shoulder
on the Plug should butt up against the shroud of the Receptacle. However, when relaxed
there may be a small gap between the receptacle and connector (due to the springs in the
Plug pushing against the Receptacle pins), as shown in Figure 22Error! Reference source

not found..

Figure 159 – Check Connectors are mated.

10.3 Alignment and Mating Procedure – Connectors with locking mechanism

• The procedure for mating a connector with Locking Mechanism is identical to the
standard ROV connector without Locking Mechanism (refer to Section 10.2).

• The locking mechanism engages automatically during mating and requires no
additional action from the operator.

Post-Mating checks:

• Correct engagement of the locking mechanism must be determined by visual
inspection (Figure 23).

• If the post mating checks show the locking mechanism is not correctly engaged (Figure

23) the plug must be de-mated following the procedure in section 10.6 and then re­mated following the procedure in section 10.3

• The shoulder on the Plug should butt up against the shroud of the Receptacle. Note: when
relaxed there may be a small gap between the two (due to the springs in the Plug pushing
against the Receptacle pins) . (Figure 22)

• As an additional confirmation that connectors are fully mated and the Plug is correctly latched
home, gently pull the Plug connector by holding the angled downward section of the Plug
gland near to the hose termination, as shown in Figure 159. If the connectors are correctly
latched and mated no axial movement in the Plug connector sho uld be present.

10.4 MANUAL DE-MATING PROCEDURE

10.5 De-Mating Procedure – Connectors without locking mechanism

Prior to commencing the de-mating of the connector pair it is assumed that the Receptacle
connector is mounted in its associated structure, and a Plug connector is mated to it.

• The operator should brace himself using the grab bars or other provided interfaces, and
ensure the connector is at chest height. By gripping the ROV handle (as shown in Figure 8),
the connector can be de-mated from the Receptacle using one smooth pulling movement
along the axis of the connectors. Pulling the ROV handle automatically releases the internal
latching mechanism. A force of 40kgf (392N) is required to de-mate the connectors.

• Once the Plug connector is fully separated from the receptacle connector, if appropriate it can
then be mated to the parking Receptacle, using the steps described in the mating procedure in
section 10.2. A dummy plug should also be mated to the remaining Receptacle, again using
the mating procedure in section 10.2

10.6 De-Mating Procedure – Connectors with locking mechanism

• Before De-mating the connector the operator must f irst release the locking mechanism.

• The locking mechanism is released by pushing the release paddle fully forward.

• The locks will disengage from the receptacle pins when the paddle is pushed fully forward.

(Figure 146)

• When this action has been performed correctly the release paddle will remain in the forward
positi on after t he opera tors hand is removed.

• The operator should brace himself using the grab bars or other provided interfaces, and
ensure the connector is at chest height. By gripping the ROV handle (as shown in Figure 28),
the connector can be de-mated from the Receptacle using one smooth pulling movement
along the axis of the connectors. Pulling the ROV handle automatically releases the internal
latching mechanism. A force of 40kgf (392N) is required to de-mate the connectors

• Note: Once the connector is De-mated the locking mechanism will re-set automatically and
can immediately be re-mated. The release paddle will automatically return to the default
position. This can be confirmed by a quick visual inspection

• Once the connector is fully separated from the receptacle connector, if appropriate it can then
be mated to a parking receptacle, using the steps described in the mating procedure in section

10.3. A dummy plug should also be mated into the remaining Receptacle, again using the
mating procedure in section 10.3

11. INSTALLATION

11.1 CONNECTOR & PENETRATOR INSTALLATION

It is recommended that the installation of all SpecTRON Penetrators and Mounted Connectors is
undertaken by Siemens Subsea site engineers or trained personnel.

11.2 HOSE ROUTING AND SUPPORT

Hose should be routed in a manner to avoid bending beyond the MBR (375mm) or kinking of the
hose. Siemens Subsea recommend that rubber inlayed plastic clamps are used to secure the
hose (such as a Stauff pipe clamp with the correct inside diameter, refer to section 3.3 for hose
diameters) and manage the routing of the jumpers.

Careful consideration should be given to the placement of the first clamp on a compliant mount
connector so as not to restrict the compliancy of the connector or impart stresses into the hose and
cable. Where clamping is required on compliantly mounted connectors, It is recommended that an
‘S’ type arrangement or similar as shown in Figure 30 is utilised to take up the potential movement
of the connector.
