This brief overview shows what OSRL does to ensure that the Containment Toolkit is ready for use. Following sections cover storage and maintenance in more detail.

OSRL is responsible for the storage and maintenance of the Containment Toolkit.
OSRL will ensure all equipment is prepared to be mobilised in the event that a member requires to use it. Full maintenance routines have been implemented for the equipment and are carried out in accordance with industry best practice.

Mobilisation Ready
Mobilisation procedures are in place and fully exercised to ensure that the equipment is prepared to be deployed with minimal delay.
It is important that members also have contingency plans and procedures in place that are tested to ensure that the notification, mobilisation and deployment process can be carried out effectively.

Are you ready?
Do you have tested notification, mobilisation and deployment plans and procedures in place?


Flowline End Termination (FLET)

Intro - components.jpg

Subsea hardware installed at the end of flexible flowlines to enable ROV operated functions, venting functionality and pressure control.

Size: 6.2m x 2.5m x 3m

Weight: 32 tonnes

There are two types of Subsea Flexable Flowline connectors due to the installation requirements onto the Capping stack there is additional padeyes for installation and due to the loads, the top housing reinforced.
