Deep water installation -- Heavy mooring and riser systems
While the move into deep water has provided exciting challenges often resulting in ingenious and novel equipment it is usually the equipment or the solution itself that is remembered and discussed. Too often one overlooks just how that novel equipment was actually installed. Perhaps one of the most exciting and ingenious equipment designs of recent times is the Submerged Turret Loading (STL) system. To date the authors have had the privilege of installing each of the 3 systems so far produced. Their work is well on course for installing the fourth during the coming summer. This paper addresses the installation of two of these systems in the summer of 94 in 350m of the hostile Halten Bank waters as part of the Conoco Heidrun development. Because the Norwegian oil industry has always been at the cutting edge of technology each new development results in the usual plethora of statistics which when presented in papers Re this are accompanied with a long list of superlatives like tallest, heaviest, deepest, quickest etc. etc. Installation work at Heidrun has a similar list. Because the 2 STL systems at Heidrun (called Direct Shuttle Loading DSL) were to be installed in such deep water the sheer size of the system components are worthy of review.
