When goods must be transferred from one ship to another one, ship to ship lng transfers are needed. Lng ships are large ships built for carrying large amounts of cargo across the world. These ships have larger and larger cargo capacities and larger drafts that do not allow them to get into smaller ports. Waiting to load or discharge goods can hurt a ship's profitability but the problem can be solved with LNG ship to ship transfer. This is accomplished by the two ships being held in place against each other while cargo is transferred. This is accomplished without going all the way into a port.
Emergency Release Systems
Modern technology is being used to improve this transfer process and make it safer. This technology provides emergency release systems that help prevent cargo spills and keep the ships and environment safe in the event of emergencies. These systems provide a managed close-down system, ship's crew having full control of operations, separation of the cargo system, and reduction of cargo spills.
Emergency Release Couplings
There is an emergency release coupling that helps when ships unexpectedly break apart. This emergency release coupling is designed to be the weak link of the LNG transfer system. In an emergency, this release coupling will close down the LNG system, separate the lines between the ships, and make sure the LNG flow is safe so there will be no cargo spill.
LNG Hydraulic Power Components
Hydraulic power units or HPUs are very new technology in the LNG ship to ship transfer practice. The HPU is another fail-safe option for ship to ship transfers using safety release equipment. This equipment allows the ship's crew to have a single control point for the release system. This allows the system to be reset and the cargo transfer to continue when the problem is resolved. Hose line stress due to the ships moving apart would be a situation that would require the system to close down.
There are other protocols and equipment systems that assure safe transfer of cargo between ships. One important factor is the training of the crews of both ships to expertly use all of the equipment used in cargo transfer from ship to ship. The law requires vessels to protect the environment and avoid cargo spills at all costs. All cargo handling equipment and safety equipment must be kept in perfect working condition. The ships, cargo, cargo hoses, and cargo handling equipment must be safeguarded. For more information on LNG ship to ship transfers go to www.lngtransfer.com.
