Remote Intervention Vehicle
The Future of Subsea Robotics
Riserless Light Well Intervention (RLWI)
A significant increase of production can be achieved in a very short timeframe intervening in existing wells.
Drilling a new well requires a rig, which needs to be contracted, and new production equipment, which needs to be built. This could take years.
With TechnipFMC’s RLWI, operators are able to increase production in a matter of months instead of years.
Increased production. Now.

In need of Intervention services for your
West Africa wells?
No need to despair. We will be back with our fully integrated vessel
Island Constructor, specially designed for RLWI missions, already in Q4 2022 –Q1 2023, so nThis will be our fifth time operating in the seas outside Angola, Nigeria and Equatorial Guinea in a multi-client campaign. For every year, we have shown a better track record of efficiency - both when it comes to putting wells back into production and significantly increasing production.
Since 2016, we have performed four multi-well RLWI campaigns in West Africa (Nigeria, Equatorial Guinea, Angola). All of them achieved the objectives safely and efficiently, resulting in significant production increase and largely paying off the project costs.
4 Campaigns = 4 Successes
TechnipFMC’s agile approach to RLWI enables Clients to drastically cut the average duration of intervention. Wells where production has reduced because of challenges such as well integrity, scaling, water production, reservoir depletion or equipment failure can be fixed with RLWI.
Our RLWI technology reduces the cost of intervention compared to rig-based interventions by removing the need for a rig and a riser, resulting in:
Less complex operations
Significantly faster production
Drastically lower environmental footprint
Why Riserless Intervention?
On a 6-wells gas-lift valve changeout campaign executed by TechnipFMC, an operator in the North Sea reported the following gains compared to a riser-based solution:
47% time reduction
73% OPEX savings (36.7 M$)
80% estimated CO2 emissions reduction
TechnipFMC’s RLWI key personnel have an average RLWI seniority of more than 14 years.
Experience matters, and it is efficiency that makes the difference.
RLWI results in significantly lower environment impact compared to rig/riser-based intervention:
Drastically lower fuel consumption both in transit and while on the well
Much shorter operations
Reduced Personnel on Board (POB), which results in less helicopter crew changes and supply vessels runs
Elimination of anchor handling vessels to moor the rig in shallow water – RLWI can safely work on dynamic positioning in less than 80 m. water
Less equipment and lighter equipment onboard requiring less power, which results in lower emissions

Why RLWI with Island Constructor
For the 22/23-campaign, we will upgrade our vessel with a brand new umbilical system. This will make operations in water depths up to 2,100 meters possible. Island Constructor arrives fully integrated in West Africa ready for operations.
Reduced environmental impact
Reduce wellhead stresses and fatigue
Reduced costs
Reduced POB and personnel exposure
Increased efficiency
Simpler setup and operations
