Marine and offshore construction equipments

  1. 1. MARINE AND OFFSHORE CONSTRUCTION EQUIPMENT FABIL .T MT15CTM003 VISVESVARAYA NATIONAL INSTITUTE OF TECHNOLOGY,NAGPUR
  2. 2. INTRODUCTION • OCEANS PRESENT UNIQUE ENVIRONMENTAL CONDITIONS THAT DOMINATES METHODS, EQUIPMENT AND PROCEDURES • MOST MARINE CONSTRUCTIONS AT SUBSTANTIAL DISTANCE FROM SHORE, THUS UNIQUE METHODS AND EQUIPMENT'S HAS TO BE USED • CONSTRUCTION OPERATION : 2000 M • EXPLORATORY OIL DRILLING : 6000 M • EQUIPMENT ARE DESIGNED TO WORK IN AND UNDER SEA AND DRAWN HEAVILY ON NAVEL ARCHITECTURE • INCLUDE BARGES, SHIPS AND CONSTRUCTION, DRILLING ,DREDGING EQUIPMENT.
  3. 3. • MAIN CONSTRUCTION ACTIVITIES OFFSHORE WIND FARM, OIL PLATFORM BRIDGE PIERS HARBOR
  4. 4. BASIC MOTIONS IN A SEAWAY • A TYPICAL FLOATING STRUCTURE HAS 6 DEGREE OF FREEDOM AND 6 BASIC RESPONSE TO WAVE • ROLL, PITCH, HEAVE, SURGE ,SWAY AND YAW
  5. 5. • VESSELS OR EQUIPMENTS RESPONDS TO COMPLEX SET OF ALL THE ABOVE MOTIONS • MOTION ARE AFFECTED BY WAVES AND TIDES
  6. 6. BARGES • LARGE FLAT BOTTOMED TOWED OR SELF PROPELLED BOAT USED FOR HEAVY GOODS AND BULK CARGO TRANSPORT • LONG FOR MINIMAL SURGE AND PITCH RESPONSE TO WAVE, WIDE FOR MINIMAL ROLL DEEP FOR ADEQUATE BENDING STRENGTH AGAINST HOG AND SAG • IN CONSTRUCTION THEY ARE USED TO CARRY ROCK REMOVED BY CLAMSHELL OR DRAGLINES AND UPON WHICH EQUIPMENT LIKE TRACKED CRANE OR LOADER ARE OPERATED • TYPICAL BARGE RUN 80 TO 160 M LENGTH ,WIDTH 1/3 OF LENGTH ,DEPTH 1/15 OF LENGTH
  7. 7. CRANE BARGES • BARGE EQUIPPED WITH SHEER LEG CRANE OR FULLY ROTATING CRANE • SHEER LEGS ARE RIGID A-FRAME SUPPORT AND MANEUVERED BY DECK ENGINE ,TUGS • WHICH CAN LIFT AN LUFF BUT NOT SWING • MAXIMUM CAPACITY 7000 T • LESS COSTLY COMPARED TO ROTATING
  8. 8. DERRICK BARGES • FULLY REVOLVING • WORKHORSE OF OFFSHORE CONSTRUCTION • CAPACITY 500- 1500 T • THE ADVANTAGE IS OPERATION IN ALL DIRECTIONS –SWING • DESIGNED UPON NAVEL AND STRUCTURAL ARCHITECTURE
  9. 9. SEMISUBMERSIBLE BARGES • STANDARD BARGE SERVING CARGO TRANSPORT OR AS SUPPORT TO CRANE ,OTHER OPERATIONAL EQUIPMENT • LARGE BASE PONTOON (FLAT BOTTOM HOLLOW METAL CHAMBER) • FULLY SUBMERGED DURING OPERATION • PROVIDE MORE STABILITY AGAINST WAVES • 4 TO 8 COLUMN THAT EXTEND THROUGH WATER SUPPORT DECK
  10. 10. JACK UP CONSTRUCTION BARGE • USE FULL FOR WORKING IN TURBULENT SEA, COASTAL WATER • FITTED WITH 4 TO 8 LARGE JACKS AND LEGS ; TUBULAR OR FABRICATED STEEL • BARGE IS TOWED TO WORK POSITION AND JACK UP FREE FROM WAVE • OPERATE ONLY IN RELATIVELY SHALLOW WATER 30-60 M , 150 EXTREME , SINCE LEGS ARE LOWERED TO SEA FLOOR
  11. 11. LAUNCH BARGES • USED FOR TRANSPORT AND LAUNCHING OF JACKETS • TO DELIVER SUBSEA TEMPLATES WHICH BECOME WORKING PLATFORM OR THE STRUCTURE ITSELF • VERY LARGE AND STRONGLY BUILT • HEAVY RUNNER BEAMS/LAUNCH BEAMS OVER WHICH JACKET WILL SLIDE
  12. 12. CATAMARAN BARGES • FOR HEAVY LIFTING IN HARBORS AND ESPECIALLY USED FOR SUBMERGED PREFABRICATED TUNNEL • TWO LONG BARGES SPREAD APART AND JOINED OVER THE TOP BY GANTRIES • GANTRIES MAY BE TWIN GANTRY TRUSSES TO ENABLE LIFTING
  13. 13. DREDGE • FOR DREDGING – CLEAR BED OF HARBOR , RIVER , OTHER AREA OF WATER BY SCOOPING OUT MUD • DIFFERENT TYPES BASED UPON EXTENT , QUALITY, TYPE OF SOIL REMOVED , DISPOSAL REQUIREMENT AND DEPTH CLAMSHELL DREDGE - BUCKET ON VERTICAL LINE ENABLES TO USE CLOSE TO EXISTING STRUCTURE. DRAGLINE DREDGE - SUITABLE FOR DIGGING TRENCHES IN SHALLOW WATER , SOFT AND MODERATE HARD SOIL LADDER OR CONTINUOUS FLIGHT BUCKET – DIG DEEPLY >40 M IN HARD MATERIAL.
  14. 14. HYDRAULIC SUCTION DREDGE – SUCK UP MATERIAL THROUGH A PIPE THEN DISCHARGE IN TO PONTOON OR REQUIRED DISTANCE CUTTER HEAD DREDGE – IN DENSE AND HARD MATERIAL , CUTTER HEAD MOUNTED AT THE END OF SUCTION LINE TRAILER SUCTION HOPPER – SELF PROPELLED VESSEL WITH JET TO BREAK UP SAND AND SUCK RIPPER TEETH TO CUT HARD MATERIAL.
  15. 15. ANCHOR HANDLING BOATS • TO PICK AND MOVE ANCHOR EVEN IN ROUGH SEA • SHORT HIGH MANEUVERABLE VESSELS • HYDRAULIC ASSIST EQUIPMENT IS AVAILABLE
  16. 16. DRILLING VESSELS • SEMISUBMERSIBLE AND BARGE TYPE • USED MAINLY FOR EXPLORATORY DRILLING • HEAVY LIFT EQUIPMENT FOR DRILL STRING • HAS CENTRAL MOON POOL( OPEN WELL ) WHICH PROVIDE DIRECT AND PARTIALLY PROTECTED ACCESS TO SEA BELOW • ABILITY TO WORK AT GREAT DEPTHS • SETTING SUBSEA TEMPLATES, PIPE LINE REPAIR AND SEA FLOOR MODIFICATION • USUALLY EQUIPPED WITH LARGE HOIST OF 500 T CAPACITY
  17. 17. FLOATING CONCRETE PLANT • MOUNTED ON LARGE , HEAVY DUTY BARGE, EQUIPPED WITH MOORING LINES TO HOLD THE BARGE IN POSITION • HAVE ; LARGE BIN FOR CA AND FA SILO FOR CEMENT SILO FOR FLY ASH AND BLAST FURNACE SLAG WATER TANK BATCHING PLANT CONCRETE MIXER – NORMALLY TURBINE MIXER CONCRETE PUMP
  18. 18. ROV • REMOTELY OPERATED UNDERWATER VEHICLES • HIGHLY MANEUVERABLE , OPERATED BY CREW ABOARD A VESSEL • COMMON IN DEEP WATER HYDROCARBON INDUSTRY • LEAST EQUIPPED WITH VIDEO CAMERA AND LIGHT • USED FOR INSPECTION,WELDING
  19. 19. THANK YOU The waves tell of ocean spaces, Of hearts that are wild and brave.
