Due to the need to arrange support ships, personnel, maintenance equipment and other auxiliary equipment to the maintenance site, and after the operation is completed, support ships, personnel, maintenance equipment and The recovery of other auxiliary equipment is therefore costly and economical.
  • the connector equipment of domestic manufacturers is mainly used in terrestrial oil and gas pipelines. It can be used to temporarily block oil and gas pipelines for 2-3 months during temporary maintenance, ensuring that oil and gas does not leak at the seals around the connectors. When used for permanent maintenance, it can be used.
  • the connector is integrally welded to the pipe.
  • domestic manufacturers have not yet produced submarine oil and gas pipeline connector equipment.
  • the domestic equipment technology of overseas submarine oil and gas pipelines is relatively mature. With the rapid development of unmanned ship technology, some special structure connectors have been developed and carried on unmanned ships. The repair of subsea pipelines can be accomplished without the need for staffing, using unmanned vessels and service connectors, as well as appropriate ancillary equipment, eliminating the need to upgrade the pipeline to unmanned vessels for pre-treatment, saving time and economic costs.
