Basic load out methodologies introduction

1. LOAD OUT BY SKIDDING
2. LOAD OUT BY TRAILERS
3. LOAD OUT BY CRANE (S)

Skidding is a method feasible for items of any weight; it would be the sole
choose for super heavy structures. The system consists of a series of steel
beams, acting as track. Each skid is provided with a hydraulic jack to
control the reaction.
The Structure will be pulled to the barge by strand-jacks system. Strand
jacks can be used horizontally for pulling objects and structures and widely
used in the oil and gas industry for skidded load out, speeds of up to 40m/hr.

3. ENGINEERING
3.0. Document preparation
Before LO activities, the following document should be approved:
 Load out Procedure
 All equipment certification
 Lay-out drawing
 LO checklist should be prepare and presented to relevant personnel in advance
and got comment as well as addition/concern if any
 Weather forecast should be provided sufficiently for LO period

3. ENGINEERING
3.1. Technical Arrangement
3.1.1. General LO procedure
Before the load out operation the barge will be moored against the load out quay.
The barge will be partly pre-ballasted in this situation. Before the load out operation
the barge will be turned into position. Once in position the barge will be ballasted
into pre-ballast condition with assistance of barge own ballast system.
The barge is to be pre-ballasted with its skid-way level between 20 mm and 0 mm
below top of quay level, continuously during the load out operations critical stage
for compensation of load transfer and tidal variation.
3.1.2. Install Strand-jacks/ Power-pack and Anchor-blocks
The strand-jacks will be installed with a small crane. This will be done under
supervision of the LO Contractor Supervisor on site. Sufficiently provide forklift /
crane assistance, LO Contractor has all other small equipment necessary for the
installation. The power-packs will be placed with a crane on the arranged platform
on the DSF. All hydraulic hoses will be installed by hand. Anchor-blocks on the
barge will be installed with a forklift /crane. This is best done when the barge is
alongside the quay

3. ENGINEERING
3.1.3. Pulling & Cutting of Strand
Strand coils will be placed in a strand cage. The position
of the cages is near the strand jacks. The strand wire will
be pulled by workmen from the Structure-location, near
the strand jacks towards the anchor block on the barge.
In this phase, the barge has to lay in LO position
perpendicular to the quay. When the total wire is pulled,
the wire will be cut by a specially prepared grinder,
which has proven to be the most effective way. The wire
will be installed at the same time in the strand jack and
in the anchor-block. (All wires must be installed in-line).
A short wave radio will be used for communication. Per Grinder Equipment
location a group of approx. Workmen are required to
pull the wire. Number of locations simultaneously
installed depending on planning.
The exact length of the strands will be determined at site
(during strand pulling) but approximate length will be
determined during the engineering phase.

3. ENGINEERING
3.1.4. Pre-Stressing of Strands
After installation of all strands, the strands must be pre-stressed. During the pre-
stressing, the barge must be ballasted to compensate the tide allowing +/-0.1 m
in relation to the quay. The pre-stressing will be controlled by the Strand-jack
Monitoring Computer.
After pre-stressing the jacks will be given one or more “release” strokes, in
order not to have any unwanted stress on the strands until the LO start.
3.1.5. Pre-ballasting of Barge
The barge must be pre ballasted according to ballast calculation. The barge will
be ballasted into this condition with help of the barge ballast system. The pre-
ballasting will be done under supervision of LO Contractor supervisor assisted
by the barge engineer.

3. ENGINEERING
3.1.6. Breakout moment
During the breakout the load will be increased according to following
procedure:
1) Strand-jacks will be activated in steps of 20% till they are pulling X% of
vertical load (X: need to be greater than the expected friction at rest of the
structure). Between each of the steps of 20% load increase, there will be a
waiting period of 1 minute, to give the system time to act. If within this waiting
time the Structure has not moved, the next 20% will be applied.
2) In case breakout is not achieved when strand-jacks pull 8% of vertical load,
the breakout jacks will be activated for pushing. This will again be done in steps
of approximately 20% of capacity. After each step there will be a 1 minute
waiting period. If within this waiting time the Structure has not moved, the next
20% will be applied until full pushing capacity is activated.

3. ENGINEERING
3.1.6. Breakout moment
During the breakout the load will be increased according to following
procedure:
3) In case breakout still not achieved investigate what could be wrong, while
load is released to guarantee a safe way of working. It can be decided to
increase pulling load within the given strand-jack-system capacity until
breakout is achieved.
In principle, breakout will only be done once.
This set of steps in order to avoid the Structure to jump forward, due to
elasticity of strand-wires.

3. ENGINEERING
3.2. LO Sequences
3.2.1. General Engineering concerns
• The LO operation will be executed by using a skidding method. Skidding
will be performed in two phases. Phase 1 is skidding from construction
location to quayside. Phase 2 is skidding from quayside onto final position
on Barge. The pulling force required will be provided by the strand jacks
attached to the DSF. During skidding, the barge tanks shall be ballasted or
de-ballasted to their required quantities as indicated in the ballast calculation
report. The barge will be ballasted / de-ballasted until the required draft, heel
and trim have been achieved before proceeding to the next stage. The speed
of the pulling and the progress of the ballast will be coordinated within each
stage. The pulling speed will be approximately 15m/hr. When no ballasting
needs to be done, the pulling speed can be increased to maximum 20m/hr.
During LO the level of the barge shall be monitored visually and by
monitoring system.

5. CONTINGENCY PLANS
5.1. Jack failure
If a strand jack fails, the reason of the failure will be investigated. LO
Contractor will bring sufficient spare parts to repair / exchange strand-jack
parts. LO Contractor will also bring 1 complete strand-jack unit spare. If the
jack itself is damaged, the complete jack will be replaced by a spare one. It must
be said that there is not much that can be damaged to the main body of the jack.
It is a relatively simple design with not a lot of moving parts.
5.2 Strand failure
All the strands have a minimum safety factor of 2. In the case that a strand fails,
the respective strand will be removed or hung up in such a way that it does not
obstruct the other strands.
5.3 Strands slacking
If an excessive number of strands are observed to become slack during LO, the
LO Contractor site manager will assess the situation with the following options;
Continue skidding if total system remaining has sufficient capacity
Re-tension the slack strands.

5.4 Hydraulic hose or fitting failure
If a hose is burst, the automatic shut off valve installed at each jack will close
immediately. The strand jack will not move and the whole system stops
immediately. The damaged hose or coupling will be replaced by a spare one,
readily available on site. A spill kit will be used to clean any oil spills.
5.5 Power pack failure
If a power pack fails, the reason of the failure will be investigated. The total
power pack can be removed and replaced or just some components. It is
common to prepare a spare power-pack directly next to the power-pack in use.
This will allow for a simple reconnection of hoses to a different power-pack in
case of any failure.
5.6 Control computer failure
The control computer is not a special computer. However, special software is
installed into the computer. This software controls the hydraulic system. If there
is a problem, the computer can be replaced by a spare one. There will always be
a spare control computer available on site for backup.

5.7 Mooring failure
Mooring failure is considered in the mooring calculation. This calculation
considers a 1-line break. The remaining mooring lines have sufficient capacity
to overcome this situation.
5.8 Ballasting failure (tidal)
Minimum 150% capacity with intact system and minimum 120% of capacity in
all tanks with any one pump system failed shall is used for ballast system design
for tide compensation.
5.9 Unfavorable weather conditions
During unforeseen and unfavorable weather conditions the decision can be
taken to stop the LO. This reduces the expose of crew and it reduces forces onto
barge and Structure. However, tidal ballasting shall continue at any time.
5.10 Deformation of skidding way
In case of extensive deformations of Skidding way a joint decision must be
taken based on the direction and location of the deformation and the stage of the
LO.

5.11. Fire on vehicles engines/Barge
Furnish sufficiently fire extinguishers in convenient location such as: on big crane
(s), barge, communication board…
5.12. Personnel crushed during the lifting execution or vehicles running into
personnel. Serious injury to personnel
Personnel are not allowed to stand under the structure during the movement or set-
down of structure. All personnel must wear high visibility clothing. The working
area must be cordoned/barricaded; the essential personnel only in it
5.13. Working at heights. Fall and serious injury to personnel
Only allowed personnel are allowed to work in height. Built scaffold platform, wear
PPE during working. The workers have to used safety belt when working in height
5.14. Electric shock/ electric safety from the barge. Injury to fatal
Regularly check and testing on all circuits. Being aware of safety for everybody
5.15. Breaking of winch lines. Serious injury, delay the LO operation due to
barge is free of mooring
Regular inspection and check during the LO

5.16. Entry into barge ballast tanks for positioning and retrieval of pumps
and hoses. Suffocation due to lack of fresh air, drowning, fall. Injury to
fatal
All ballast tanks must be vented as soon as possible prior to execution. Gas
tested prior to entry. Ballast supervisor should make a visual check of tank
condition prior to entry. Obtaining entry to enclosed space permits. Install
ladder from barge deck for working. Wear suitable PPE with lifebuoy attached.
Personnel are not allowed to access if water level is deeper than 50mm.
Appointed personnel on tank hole when personnel working in tanks. No pump
function test as well as pump in and out whilst personnel in tanks. Tags are
required for involved personnel
5.17. Working at night, bad light condition. Cause accident due to not being
seen, low light
Lights and generator will be available on barge. All tank holes, covers should be
closed or cover over when they are not in use. Supervisor should manage the
number of personnel working on barge

5.18. Barge touching bottom of sea during the LO. Damage to barge, the
LO operation must be cancelled
Ballast calculation, mooring for the LO to be taken into account of tidal
variations to ensure that barge is not grounding. Sea sounding and if necessary,
LO area must be dredged to ensure sufficient depth of water
5.19. Barge structure failure during the LO
Barge strength will be checked by the load out contractor before load out
operation
5.20. Instability of the barge. Cause disaster
Stability check for the structure on barge during & after the LO. LO operation
will be stopped if calculation shows that the stability is not ok on barge
5.21. Failure of ballast system during the LO. LO will be aborted
Ballast calculation will determine the number of pumps required and
contingency. Spare pumps are always available to replace. Ballast system must
hold the barge against the tide during the rectification of any problems during
the LO

5.22. Fatigue personnel due to long hours. Untrained persons carrying out
tasks
Work shifts and patterns will be organised to ensure that personnel do not work
excessive hours. Qualified employees will supervise untrained employees
5.23. Injury
All participants must wear PPE: High visibility clothing's, glasses, shoes,
helmet…not permitted to enter if they do not have enough overall
5.24. Falling materials from structure or items. Injury to personnel &
damage to property
Wear PPE during the working. Securing objects to ensure that they cannot fall
5.25. Cross over ballast pipes
Warning heavy equipment & others not to cross over/run over ballast pipes

LOAD OUT BY TRAILERS SYSTEM
Depending on the required load-carrying capacity, the 2, 3, 4 or 6-axle modular
transporter units can easily be coupled with one another. A PPU supplies the
hydrostatically driven SPMT with pressure oil for the drive, steering and lift
operations. The electronic steering system is controlled by means of an on-
board computer that can be configured to control an individual vehicle or
groups of coupled units. The units can drive in all directions and negotiate
curves

Before commencing the LO operation, shifting Structure from the fabrication
yard to jetty, the following steps will be followed 2 stages below:
Stage 1: Jacking-up Structure on Fabrication yard & cutting 04 legs of
structure:
- The Structure was arranged on temporary supports with requirement high from
Load out Frame (LO Frame) of structure to the ground.
- To make the trailer suitable to the height and better load distribution on
trailers, pre-install units of Load Spreader Beams (hereinafter called L.S.B) on
trailer platforms, insert rubber pads to increase friction.
- Bottom of the Structure will be marked for correct trailer arrangement
underneath. In addition, manoeuvring path is identified by marking lines
alongside the lengthwise of the Structure on the ground, the trailer wheels to be
driven in between these lines.
- All obstructions which interfere with the trailer’s moving path will be removed
(junction box, cable, stone, etc…)

3.1. Procedure
- Place thin rubbers at top of the Load Spreader Beam (L.S.B) to increase
friction between the Structure and trailers.
- After finishing all the preparation, LO Contractor will perform the test lift for
Structure. Before performing the trial lift. Notices will be informed to involved
Parties prior to lifting test.
- Place thin rubbers at top of the Load Spreader Beam (L.S.B) to increase
friction between the Structure and trailers. Jacking-up the trailer platforms till
top of L.S.B on trailers touching the bottom of Structure
- Lashing Structure to trailers by chain ropes. Installing tie-back beams,
stoppers to secure the stability of trailers & structure supports
- Continue to jack simultaneously the trailer platforms up 1350mm clear from
supports (Drawing No. 02). This height is fixed during the load out operation.

3.1. Procedure
3.1.6. Methodology of Barge Mooring
Step 1:
Define the location for mooring the barge & paint marking first. Then, turn the
barge; arrange all mooring lines as designed diagram.
Mooring her stern freely (not so hard) against the jetty ready for the operation.
Tugboat, forklift etc. will be used during the mooring operation of barge.
Step 2:
When the tide rising, 03hrs prior to load out operation, utilizing winches and
chain blocks on each side for adjustment the barge coming into right position
for load out. Then, fasten, moor lines by winches, chain-blocks.

3.1. Procedure
3.1.7. Ballast Control
To ensure proper monitoring of the ballast water transferring between the tanks,
one experienced person will be assigned to supervise the ballast operation, the
sounding value, barge level at each step etc. This person will strictly monitor the
pumps that he was assigned and to control these pumps if necessary. He should
also advise the ballast engineer immediately of any mal-functioning such as
sudden loss of pressure or other concerns.
It is extremely important to confirm the working condition of ballast pumps and
ballasting operation. Walkie-talkies will be used on private channels to control
ballast pumps. The communication from the controllers is systematic. Request
or reply must be in the order of tank number to avoid confusion.
Supervising works should focus on 2 notices:

3.1. Procedure
3.1.7. Ballast Control
1) The barge will be checked all time, the barge check include: Trimming check
and heeling check, one responsible worker check the ullage of the barge both
side port and start-board each end of the barge. The result of measurement have
to be sent to ballast supervisor by walkie-talkie each 5’ for treatment, max
trimming allowable is 300cm and max heeling allowable is 100cm.
2) Pumping duration must be counted by stopwatch. Pump capacity is shown by
manufacturer & defined by pumping in tanks

3.2. LO sequences
The actual LO operation is commenced when the first axle of the trailer is on
the ramps (link-span) and finished when the whole Structure sitting correctly on
the grillages.
The Sequences is applied as follows:
Step 1: Barge is ballasted to the pre-determined condition readiness for LO with
the tide level meeting the calculated tide in the ballast calculation.
Step 2: At this time, power pack of SPMT will simultaneously pull the trailers
onto the ramps (link-span). Prior to commence this step, check carefully
mooring lines and winches.
The time duration spent for the movement of trailers that is fixed, the first axle
of trailers must stop at the first marking and ballast water will be transferred as
the ballast calculation.

3.2. LO sequences
Step 3: When ballast water volume gets satisfied level as ballast calculation for
the Structure moves on Barge, commence to move the system. Tide level is
constantly checked in a precise manner and informed to the ballast supervisor.
- During the movement, ballasting operations will be continued according to
ballast calculation.
Visual check carefully stability of structure before commencement next steps.
- Regular inspection and control the clearance between link-span and barge
deck approximately (20 – 100mm).
Step 4: Trailers got the Grillages position, stop the trailers, lower the structure
onto the grillages on the barge’s deck. During the lowering check all contact
points between the Structure and grillages

3.2. LO sequences
Step 5: Get all agreement of Company’s Representative/MWS and commence
the sea-fastening.
Step 6: After finishing the sea-fastening (approximately 30%) & MWS allows
LO contractor to take trailers out then remove all lashing slings, tieback beams
and lowering trailer platforms to pull trailers out to the jetty.
Step 7: Ballast for towing will be done after receiving the Ballast for sea-
towing Report

3.3. Post-LO activities
- Sea -fastening, welding immediately in order to secure the Structure to
the barge. Welding at main grillages before taking trailers out to the Jetty
- De-rigged trailers & gather other unnecessary equipment for demobilization.
- Disconnect ballast pumps, piles & taken out from the barge deck for
demobilization.
- Reinstallation of any barge furniture (which are removed for load out) will be
done
- Ballast for sea-towing will be done right after receiving the Ballast for sea-
towing Reports
