Abstract
An offshore loading system especially suited for transferring petroleum products from a floating production vessel to a marine tanker. The system comprises a cantilevered support boom mounted on the deck of the production vessel, a fluid conduit extending generally horizontally along the boom from a riser on the deck of the production vessel, an articulated loading arm connected to the outboard end of the horizontal conduit, and a multiple swivel joint for connection between the outboard end of the loading arm and a pipe manifold on the deck of the marine tanker. The inboard end of the loading arm is connected by swivel joints to the outboard end of the horizontal conduit to facilitate pivoting the loading arm in both a vertical plane and a horizontal plane. An inboard drive sheave secured to the inboard end of the loading arm is connected to a support cable for raising and lowering the arm, and a pantograph drive system of sheaves, cables and hydraulic cylinders interconnects the inboard drive sheave and an outboard sheave for raising and lowering an outboard section of the arm.
