Optime Subsea has launched a device that removes the umbilical for in-riser based tubing hanger operations, with Norwegian firm Aker BP as the first client for the new technology.
The device is expected to increase safety, and reduce operational time, cost, and environmental risks.
Optime Subsea’s Remote Operated Controls (ROC) system eliminates the umbilical that normally controls the tubing hanger in such operations. Without the umbilical, it is also possible to remove a costly and large topside hydraulic unit, as well as increasing safety by not needing to clamp any umbilical to the riser.
In a statement, Optime said the operation is normally time-consuming and would result in hours of higher-risk operations. However, using its ROC system will significantly reduce the time taken.
Optime Subsea Business Development manager Trond Løkka said: “Until completing a few runs we will not be able to affirmatively state the total days in savings for subsea well completions, but we are convinced that this system will provide Aker BP and all other operators days, not hours, in savings, for every single well.
“Although today’s market is hard to predict, we are definitely able to see the future with this system being ready by end of the year – there will be tremendous industry-wide cost savings for everyone.”
Optime Subsea’s relationship with Aker BP began with its Subsea Controls & Intervention Light System (SCILS) on the Odfjell-operated semi-submersible drilling rig Deepsea Nordkapp.
This strategic collaboration now extends with Aker BP bringing Optime’s Remotely Operated Controls System (ROCS) onboard the same rig.
Aker BP drilling and well special advisor Mads Rødsjø said: “In Aker BP we are continously working on improving our subsea operations, making them safer, simpler and more cost efficient.
“This contract award will be an important part of this work, as well as acknowledging the continued successful collaboration with Optime. With ROCS, Aker BP can substantially reduce its completions time and cost by removing the umbilical.”
Last month, Aker BP and partners started production from the first Ærfugl phase 2 well in the Norwegian Sea, three years ahead of the initial plan.
