Abstract: A valve arrangement for a hose end coupler of a transfer hose for the offloading of hydrocarbons from an offshore floating production storage and offloading vessel (FPSO) to a shuttle tanker is described. The valve arrangement comprises a linear valve comprising a linear valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open; a secondary valve comprising a secondary valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open; the linear valve actuator and the secondary valve actuator are operatively coupled so movement of the linear valve actuator effects a corresponding movement of the secondary valve actuator. A hose end coupler with the valve arrangement, and a transfer hose and transfer system and method incorporating such a hose end coupler with the valve arrangement are also described.

Abstract: A lock has a tumbler with a camming surface, the tumbler being urged outwardly when the key is inserted. As the lock barrel moves inwards, the tumbler rotates about an axis against a spring force to pass a formation on the lock housing and, once past the formation, latches behind the formation to prevent the barrel from moving back outwards.
