EPRS & Subsea Services






Although pipelines are accepted as a safe form of energy transportation, failures can and do occur. Damage sustained to a submarine pipe in particular, can prove challenging to repair. As identified in DNV GL RP F113 Subsea Pipeline Repair, the main cause of pipeline damage is caused by a degradation mechanism such as corrosion, Hydrogen induced stress cracking (HISC) or physical damage such as unstable seabed conditions, anchor strike, dropped objects and trawl gear interference. In cases where pipeline damage has occurred, the damaged section may need to be cut from the pipeline and replaced with a new pipe section or repaired in-situ. As well as pipeline repair, STATS temporary isolation solutions allow safety critical valve replacement, tie-in or re-routing of pressurised pipelines.
STATS has developed a range of subsea pipeline repair solutions which includes inline isolation tools (Tecno Plug), hot tap and plugging equipment (BISEP), mechanical connectors, structural repair clamps and pipeline retrieval tools.
Subsea Temporary Line Plugging

The BISEP® when deployed subsea provides the highest level of hot tap installed pipeline isolation in the industry. Complying with all relevant subsea isolation guidelines, the BISEP ensures safe worksite conditions for divers from breaking containment to reinstatement.

Despite good pipeline design and integrity management schemes pipelines can and do get damaged. A pipeline’s out of service time, following an incident, can be significantly reduced with strategic investment in an Emergency Pipeline Repair System.
Read MoreSubsea Pipeline Repair Clamps

STATS subsea repair clamps feature a robust design to provide effective leak sealing in the harshest conditions. The dual seal design provides pressure containment with annulus test capabilities and, where grout filled, radial support to the pipe.
Read MoreSubsea Mechanical Pipe Connectors

Subsea mechanical Connectors are used for the tie-in or repair of pipelines and risers. The slipover design and mechanical locking assembly provides a flanged connection without the need for hyperbaric welding, available from 2” up to 48”.
Read MoreAbandonment and Decommissioning

Subsea Pipe End Plugs can be supplied as a temporary or permanent cap to terminate open pipe ends. They provide a robust isolation barrier to prevent seawater ingress or residual hydrocarbon escape to the environment.
Read MorePipeline Retrieval Tool

Pipeline Retrieval Tools facilitate the laydown or recovery of subsea pipelines and are designed for lifting large diameter pipe and heavy loads.
Read MoreSubsea Mechanical Hot Tapping Fittings

Subsea Mechanical Hot Tapping Fittings facilitate the connection of new branch pipework to existing infrastructure without the requirement for hyperbaric welding or pre-installed tees.
