Basic load out methodologies introduction

  1. 1. 1. LOAD OUT BY SKIDDING2. LOAD OUT BY TRAILERS3. LOAD OUT BY CRANE (S)
  2. 2. 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 widelyused in the oil and gas industry for skidded load out, speeds of up to 40m/hr.

  15. 15. 3. ENGINEERING3.0. Document preparationBefore 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
  16. 16. 3. ENGINEERING3.1. Technical Arrangement3.1.1. General LO procedureBefore 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 operationthe barge will be turned into position. Once in position the barge will be ballastedinto 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 mmbelow top of quay level, continuously during the load out operations critical stagefor compensation of load transfer and tidal variation.3.1.2. Install Strand-jacks/ Power-pack and Anchor-blocksThe strand-jacks will be installed with a small crane. This will be done undersupervision of the LO Contractor Supervisor on site. Sufficiently provide forklift /crane assistance, LO Contractor has all other small equipment necessary for theinstallation. The power-packs will be placed with a crane on the arranged platformon the DSF. All hydraulic hoses will be installed by hand. Anchor-blocks on thebarge will be installed with a forklift /crane. This is best done when the barge isalongside the quay
  17. 17. 3. ENGINEERING3.1. Technical Arrangement3.1.3. Pulling & Cutting of StrandStrand coils will be placed in a strand cage. The positionof the cages is near the strand jacks. The strand wire willbe pulled by workmen from the Structure-location, nearthe strand jacks towards the anchor block on the barge.In this phase, the barge has to lay in LO positionperpendicular 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 wirewill be installed at the same time in the strand jack andin the anchor-block. (All wires must be installed in-line).A short wave radio will be used for communication. Per Grinder Equipmentlocation a group of approx. Workmen are required topull the wire. Number of locations simultaneouslyinstalled depending on planning.The exact length of the strands will be determined at site(during strand pulling) but approximate length will bedetermined during the engineering phase.
  18. 18. 3. ENGINEERING3.1. Technical Arrangement3.1.4. Pre-Stressing of StrandsAfter 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 min relation to the quay. The pre-stressing will be controlled by the Strand-jackMonitoring Computer.After pre-stressing the jacks will be given one or more “release” strokes, inorder not to have any unwanted stress on the strands until the LO start.3.1.5. Pre-ballasting of BargeThe barge must be pre ballasted according to ballast calculation. The barge willbe ballasted into this condition with help of the barge ballast system. The pre-ballasting will be done under supervision of LO Contractor supervisor assistedby the barge engineer.
  19. 19. 3. ENGINEERING3.1. Technical Arrangement3.1.6. Breakout momentDuring the breakout the load will be increased according to followingprocedure:1) Strand-jacks will be activated in steps of 20% till they are pulling X% ofvertical load (X: need to be greater than the expected friction at rest of thestructure). Between each of the steps of 20% load increase, there will be awaiting period of 1 minute, to give the system time to act. If within this waitingtime 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 stepsof approximately 20% of capacity. After each step there will be a 1 minutewaiting period. If within this waiting time the Structure has not moved, the next20% will be applied until full pushing capacity is activated.
  20. 20. 3. ENGINEERING3.1. Technical Arrangement3.1.6. Breakout momentDuring the breakout the load will be increased according to followingprocedure:3) In case breakout still not achieved investigate what could be wrong, whileload is released to guarantee a safe way of working. It can be decided toincrease pulling load within the given strand-jack-system capacity untilbreakout is achieved.In principle, breakout will only be done once.This set of steps in order to avoid the Structure to jump forward, due toelasticity of strand-wires.
  21. 21. 3. ENGINEERING3.2. LO Sequences3.2.1. 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.
  22. 22. 3. ENGINEERING3.2. LO Sequences3.2.2. Pre-LO activities- Clear area of obstructions.- Install Ballast System on barge.- Ballast Barge to pre-LO requirement.- Align Barge for LO condition.- Install and tension mooring lines.- Install Strand-jacks and Power-packs on DSF.- Pre-tension strand-jacks per individual strand.- Maintain barge level by visual inspection.- Check functionality of all equipment.- Check weather condition visually and with daily report.- Monitor tide and note any discrepancy.- Preparation skid way for skidding operation.
  23. 23. 3. ENGINEERING3.2. LO Sequences3.2.2. Pre-LO activities- Remove any obstructing installation or attachments to the structure (forexample scaffolding).- Check strands for dirt, grease or damages, clean by pressure jet if necessary.- Carry out meeting and brief all involved personnel.
  24. 24. 3. ENGINEERING3.2. LO Sequences3.2.3. LO activities- Align and secure barge, check tension mooring lines.- Verify alignment of skid beam to barge.- Clear LO area and barge of unnecessary personnel.- Re-confirm barge condition, draft, trim, and heel. Adjust ballast if necessary.- Re-check weather condition.- Obtain written approval from Company and warranty surveyor.- Start pulling of strand jack.- Note first movement of Structure and its corresponding pulling force.- If Structure does not breakout at maximum expected pushing / pulling force ofjacks. A meeting with all parties will be called- If breakout is successful, maintain pulling force and speed- Observe alignment of DSF on the skid-beam; adjust pull to the right and leftstrand jacks to re-align DSF if necessary
  25. 25. 3. ENGINEERING3.2. LO Sequences3.2.3. LO activities- Bundle strands during skidding with straps or rope- Prepare for cross-over.- Follow pulling steps as per Ballast Calculation.- Ballast Barge as per ballast sequence.- Check if Barge is not restricted between the quays, check fenders.- Monitoring Structure position to markings on skid beam.- Continuously monitor barge level and tide.- Continue pulling and ballasting until Structure reaches final position.- Alignment of Structure will be done when approaching 2.0m of the finalposition. This is achieved by applying different pulling forces on the left/rightstrand jacks.
  26. 26. 3. ENGINEERING3.2. LO Sequences3.2.3. LO activities- Prepare for alignment of the DSF perpendicular to skidding direction. This canbe done by guides, to make sure the DSF will reach the exact correct endlocation.- Confirm final position.
  27. 27. 3. ENGINEERING3.2. LO Sequences3.2.4. Post-LO activities- Cutting of strands behind Anchor-blocks- Remove strands from strand-jacks and anchor-blocks- Remove strands from barge.- Disconnect strand-jacks and power-packs- Remove strand jacks and power packs by forklift/crane.- Remove anchor blocks from barge- Remove Ballast System from barge- Remove mooring system.- Install temporary sea fastening.- Demobilize all equipment.

  36. 36. 5. CONTINGENCY PLANS5.1. Jack failureIf a strand jack fails, the reason of the failure will be investigated. LOContractor will bring sufficient spare parts to repair / exchange strand-jackparts. LO Contractor will also bring 1 complete strand-jack unit spare. If thejack itself is damaged, the complete jack will be replaced by a spare one. It mustbe 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 failureAll 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 notobstruct the other strands.5.3 Strands slackingIf an excessive number of strands are observed to become slack during LO, theLO Contractor site manager will assess the situation with the following options;Continue skidding if total system remaining has sufficient capacityRe-tension the slack strands.
  37. 37. 5. CONTINGENCY PLANS5.4 Hydraulic hose or fitting failureIf a hose is burst, the automatic shut off valve installed at each jack will closeimmediately. The strand jack will not move and the whole system stopsimmediately. 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 failureIf a power pack fails, the reason of the failure will be investigated. The totalpower pack can be removed and replaced or just some components. It iscommon 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 incase of any failure.5.6 Control computer failureThe control computer is not a special computer. However, special software isinstalled into the computer. This software controls the hydraulic system. If thereis a problem, the computer can be replaced by a spare one. There will always bea spare control computer available on site for backup.
  38. 38. 5. CONTINGENCY PLANS5.7 Mooring failureMooring failure is considered in the mooring calculation. This calculationconsiders a 1-line break. The remaining mooring lines have sufficient capacityto overcome this situation.5.8 Ballasting failure (tidal)Minimum 150% capacity with intact system and minimum 120% of capacity inall tanks with any one pump system failed shall is used for ballast system designfor tide compensation.5.9 Unfavorable weather conditionsDuring unforeseen and unfavorable weather conditions the decision can betaken to stop the LO. This reduces the expose of crew and it reduces forces ontobarge and Structure. However, tidal ballasting shall continue at any time.5.10 Deformation of skidding wayIn case of extensive deformations of Skidding way a joint decision must betaken based on the direction and location of the deformation and the stage of theLO.
