CoselleTM Loading Facility
Loading facilities for Sea NG ships are relatively simple and can be configured in a variety of ways to meet the customer’s needs.
Coselle™ System loading facilities consist of standard, readily available equipment used in gas plants and re-injection systems throughout the world. The key components for the loading facilities are:
- Gas dehydration
- Gas compression
- Gas transfer
- Control, ESD and communication systems
The loading facilities incorporate pipeline-style compression for natural gas. The gas to be loaded into the Coselle™ must be pipeline quality and must be dehydrated. Coselles™ can accommodate “rich gas” mixtures.
The docking structures required to support these facilities are also typical of marine oil and gas terminals. They can be located either onshore or offshore.
There are many options for configuring Coselle™ System loading facilities. The ultimate configuration depends on specific project parameters. A typical example is shown below.
This unloading arm technology is similar to that currently used for LNG re-gasification.
A safety system provides flow shutoff, connector isolation, blow-down and disconnect in event of a mooring line issue or vessel movement excursion beyond pre-set limits.
For onshore loading, gas is delivered onto the ship via a dedicated berth at a jetty/pier.
Offshore loading may be preferable where port conditions limit access.
For offshore loading in protected waters, facilities can be mounted on a barge. In unprotected waters, a sea-going vessel or offshore platform can be used.
Transfer of the gas to the ships can be either by barge or platform based articulated loading arm(s) or by offshore buoy, depending on site-specific considerations. As with onshore facilities there are a number of options for configuring Coselle™ System offshore loading facilities. Sea NG works closely with customers to optimize facilities to meet their needs.
All loading systems will be designed to internationally accepted standards.
