MARINE ICE-RESISTANT FLOATING PLATFORM |
摘要 |
FIELD: transport.SUBSTANCE: invention relates to ship building, particularly, to production of ice-resistant platforms for exploration of freezing sea offshore oil and gas deposits. Proposed platform is equipped with remote turret assembly consisting of the block accommodating the turret and located outside platform hull to allow the latter to turn in external force main vector direction and to be retained in place by anchor system connected with said turret. Said block with turret are located under water ahead of fore perpendicular at the distance not smaller than half the difference between platform maximum length and that between perpendiculars. Block top is located level with the platform base plane. Said block features the hull axially symmetric shape with respect to vertical axis and is secured to platform hull with the help of corbel shaped to trihedral pyramid with clearance between ribs and facing the hull stem by its base. Pyramid two ribs are located in the platform base plane while third rib rests on said stem. Said rib features sharpened top edge.EFFECT: higher safety of turret, anchor and riser lines in ice.2 dwg |
