- Used in shuttle-tankers to receive the crude oil from cargo terminals, from cargo buoys and from FPSO’s and FSU’s.
- The shape of the bow of these ships must be adapted to the installation of these systems.

- Traction winch
- Chain stopper

- Bow door
- Loading manifold
- Hose handling winch
- Forward/aft movement of the chain stopper, or adjustable roller fairlead
The following equipment should be locally operated from the bow area:
- Rope pulling unit/stowing arrangement

In the centre area of the BLS manifold room, detectors should be installed underneath the forecastle platform deck.
The following fixed detection sensors should as a minimum be installed and connected to the vessels fire and gas detection systems, giving alarms on the bridge when activated:

- 2 flame detectors
