Wintershall Dea to rent subsea well completion and intervention systems from Optime Subsea

World Oil Staff February 23, 2023

(WO) — Optime Subsea has signed a long-term framework agreement with Wintershall Dea for the rental of its remote-controlled subsea well completion and intervention systems. The agreement includes three Remotely Operated Controls Systems (ROCS) and two wireless electric subsea control and intervention systems (eSCILS), as well as technical service personnel to support operations.

The contract is valid for three years with two additional two-year options, and if exercised, could generate total revenues of around NOK 500 million ($48.51 million).

Optime Subsea's solutions are tailored to simplify subsea operations, with less equipment offshore, lower weight, logistics, HSE risk, emissions and costs.

Wintershall Dea will utilize the ROCS and eSCILS equipment at its operated fields on the Norwegian continental shelf.


The ROCS is a fully battery-powered and umbilical-less system for well-completion operations, eliminating the need for a costly and heavy umbilical that normally runs from the topside to seabed to control the tubing hanger during completions. This also means that a large topside hydraulic unit is not required.

In total, this avoids the mobilization of approximately 50 tonnes of topside equipment. Further, ROCS is mobilized in a single basket, prepared and made up onshore, allowing it to be ready to run immediately when offshore, from a rig.

In addition, the ROCS will be supplied with Optime Subsea’s universal landing string system (Panpipe), capable of being sheared and sealed on all its length.

Meanwhile, eSCILS is a battery-powered and umbilical-less subsea access device for well interventions and workover operations, with a small footprint that makes it easy to transport and mobilize. eSCILS is lowered down to the seabed next to the well and can be connected to any type of subsea tree. A computer is all that is needed for a topside control system, no additional rig equipment is needed.

With a footprint as little as 3,5 x 2,5 meters, eSCILS can be transported to and from the rig on a ship and be mobilized and demobilized in one day. As a result, operations can be done significantly safer, faster, and more cost-efficient than conventional solutions.

Optime Subsea will manufacture all equipment at its headquarters in Notodden, Norway.
