update mar-apr 2004 - Punj Lloyd

updatelaying of the longestpipeline lengthof 2000 m by HorizontalDirectional DrillingThe offshore pipelinesare laid with accuracyof ±5 m while theplatform position is fi xed.A comprehensive metrologyis performed by diversto fi nalize the length ofthe dogleg based on theactual position of the laidpipeline. The dogleg spoolis fabricated on the bargeitself. The fi nal tie-in isdone in 2G position atthe location above theriser clamp.PT. Punj Lloyd Indonesiaacquired a 230 ft bargewith a deck loadingcapacity of 10 T/m 2 . Thebarge is fi tted with fourdavits each for SWL (asafe working load) of35 T and is supportedon four point mooringsystem. The mooringwinches have a capacityof 35 T with a drumcapacity of 900 mtr.Two cranes of 150 Tand 50 T are mountedon this barge in order tocarry out the installationof riser and doglegassemblies. The barge isfi tted with dual RTK GPSPositioning System. Priorto mobilisation at site thepositioning systems arecalibrated for accuracy.Another milestonesuccessfully met wasthe laying of the longestlength of 2000 m pipelineby Horizontal DirectionalDrilling. The pipestringhad to be prepared andwet stored in the opensea, with currents ofthree knots. This wasthe longest HDD lengthundertaken by Punj Lloyd.update A Rajendrapulled with designcalculations, sketches,assessment, constantmonitoring, usingunderwater divers’expertise
