> What is Plug n’ Play?
– “conveys a message of interconnectivity and the ability to connect modular equipment in an
easy and effective way, to form a production system that is fit for purpose and rapid to
deploy”
> Plug n’ Play Aspiration:
– Rapid engineering & delivery of the project
– Full interconnectivity between modular subsea components
– Re-use of subsea equipment from field to field (the circular economy)
– Interoperability with present and future systems
– Flexibility to use a range of supplier specific subsea components

> What is the Reusable Control System?
– A system where all components are designed for recovery and re-use
– Designed to operate for 4-5 years before recovery / refurbishment / re-use
> Current practise combines topside and subsea equipment;
> Deploying the equipment at the drill site allows it to be recovered and easily moved to the next drill
site;
> Reusing the umbilical is a possibility however this study has concentrated on systems deployable
local to the drill site.

> Expensive item of equipment to purchase and install;
> Considered to be a long lead item contributing to longer project executing times;
> Unlikely that the umbilical could be recovered and re-used multiple times;
> Umbilical failure would result in a full replacement being installed at considerable cost;
> Considerable cost to retrofit a J-tube to an existing host facility should there be no spare J-tubes
available to house the umbilical.

The umbilical contains a number of hoses and cables providing the following services:
> Low and high pressure hydraulic supply lines;
> Chemical injection supply lines;
> Power supply lines;
> Communication supply lines.
What services does the umbilical provide?

> All concept options are deemed to be technically viable, demonstrating that there are several options for developing a reusable control system;
> The power requirements can be met using renewable power sources:
– Approximate peak power required 49kW, during start up;
– Normal operation approximate power required 100W;
– Renewable power sources can supply power ranging from 36kW to 600kW.
> High level costs for each type of architecture were generated for 10km Tie-back of the Future;
> Each concept option was assessed against the following criteria:
– System Robustness;
– Installability;
– Reusability;
– Maintenance Access;
– System Average TRL status;
– Cost Differential to least expensive.
