02 May 2018KKI have designed a unique, fit-for-purpose, cost effective and compact Choke Insert Running Tool (CIRT) for offshore choke interventions.
The choke is often considered a critical component in the system and in today’s subsea architecture it is common-place for a separately retrievable choke insert to be specified.
KKI's design uses a single bolt connector for ease of insert installation and removal and is modular in design for either diver or ROV maintenance.
Market research has indicated that traditional ISO compliant tooling interfaces were causing envelope size problems for system integrators. Additionally, it was found that the running tools traditionally specified by control system engineers were overcomplicated for choke retrievals. KKI took this on-board and designed a simple, fit-for-purpose, cost effective and compact running tool.
The choke insert running tool is designed to provide protection to the insert during deployment, and guidance into the choke body during installation for a safe and controlled intervention.
The running tool consists of the following key components:
– Guide chute
– Gearbox/Jacking mechanism
– Soft landing device
– Tool lockdown/load reaction mechanism
– Failsafe insert lifting and securing interface.
The CIRT gearbox has an ISO-13628 class IV mechanical override which when deployed is operated with an ROV torque tool to facilitate the retrieval and installation of the choke insert.
The CIRT is adaptable to installation contractor demands including variable offshore conditions; shallow or deep water. KKI's range of shipping, handling, testing and protection equipment complements the CIRT to ensure offshore interventions are executed as quickly and safely as possible.
The CIRT can be provided with its standard ISO-13628 compliant interfaces or to suit customer or project requirements.
