Abstract

A method is for performing an approach to position a ship in side-by-side configuration alongside a floating offshore storage facility, for transfer of fluid cargo between the floating offshore storage facility and the ship. The method may comprise connecting a helper vessel to the ship, moving the ship on an approach path toward the floating offshore storage facility using the helper vessel, and obtaining a component of sideways movement of the ship by applying thrust from the connected helper vessel, to facilitate moving the ship on the approach path and position the ship in the side-by-side configuration. The ship can be brought into the side-by-side configuration alongside the floating offshore storage facility, at least one transfer pipe can be connected between the ship and the floating offshore storage facility, and communication can be opened through the transfer pipe to communicate fluid cargo between the ship and the storage facility.

Abstract

Method and system for transferring fluid cargo between a first vessel (1) and a second vessel (10) at open sea in a Parallel configuration, and where the first vessel (1) is equipped with a cargo connection point (6) and where the second vessel (10) is equipped with cargo manifold (14), and where a tubular line (20) is connectable between the cargo connection point (6) and the cargo manifold (14) wherein the method includes: - attaching a self-propelled buoy (12) to the second vessel (10); - connecting a cargo connection (16) between the self-propelled buoy (12) and the cargo manifold (14); - connecting a cargo line (18) between the cargo connection point (6) and the self- propelled buoy (12); - transfer cargo between the cargo connection point (6) and the cargo vessel (10); - relying on the self-propelled buoy (12) to keep the self-propelled buoy (12) within predetermined distance boundaries (36, 38) from the first vessel (1) also when the self-propelled buoy (12) is attached to the second vessel (10).

Abstract

Methods and systems are for transferring fluid cargo between a first vessel and a second vessel at open sea in a Parallel configuration. The first vessel is equipped with a cargo connection point and the second vessel is equipped with cargo manifold. A tubular line is connectable between the cargo connection point and the cargo manifold. The method can include attaching a self-propelled buoy to the second vessel; connecting a cargo connection between the self-propelled buoy and the cargo manifold; connecting a cargo line between the cargo connection point and the self-propelled buoy; transferring cargo between the cargo connection point and the cargo vessel; and relying on the self-propelled buoy to keep the self-propelled buoy within predetermined distance boundaries from the first vessel also when the self-propelled buoy is attached to the second vessel.

Abstract

A system and method are for transferring fluid cargo between a cargo vessel and a cargo connection point at open sea where the cargo vessel is required to keep an end portion of the cargo vessel up towards the resultant element force direction, wherein at least one self-propelled buoy, that is designed to be in fluid connection with the cargo connection point, is connectable to a side portion of the cargo vessel, there being a cargo line that is connectable between the self-propelled buoy and the cargo vessel, and where the self-propelled buoy is designed to keep the self-propelled buoy within predetermined radial distance boundaries from the cargo connection point also when it is attached to the cargo vessel.
