CAPABLE
Large Vessels Testing chambers up to ø1000 mm diameter and 2800 mm height. High Precision Pressures are accurate within ±1 bar, from ambient to 800-bar. Comprehensive Control Adjustable rates of pressure change and intermediate dwelling. Programmable Testing Pressure profiles may be created and executed from stored memory. Managed Data Archived and query-able test
results with live sensor telemetry during testing. Cool Operation Testing available to -5°C when using external refrigeration system. Extendable Modular penetrators mounted in pressure lids adapt to almost any electrical, optical or hydraulic testing requirements

PRODUCTIVE
High Uptime Test baskets, multiple lids or vessels enable productivity between cycles. Quick Cycles Maximum pressure excursions reachable in 7-12 minutes. Quick Turns Pressure lids are exchangeable in 6-9 minutes, requiring no mechanical fastening. Resource Wise A single light-load crane may be used for both pressure lids and test devices. Extended Testing Dual vessel availability per system allow testing in two pressure mediums. Ergonomic Top lid of pressure vessel is waist high, easing test setup and device interchange.

Light Completion Intervention System (LCIS)

The LCIS is part of the next generation multiCompletionSystem that enables use of lighter and smaller IMR/FSV vessels, challenging traditional operations normally performed from a drilling rig. The cost savings are significant for the operator.

LCIS is a multipurpose tool for installing, testing and operating subsea equipment such as XT’s, Choke Modules and Manifolds. The main objectives are providing our customers with a high flexibility, operation efficiency and contingency, low OPEX and no CAPEX – while maintaining and implementing the highest safety standards.

The LCIS may be run as a stand-alone unit (subsea skid) or as part of a system stack-up, and may accommodate traditional adapters as x-overs to the main installation/operating object. The main difference from a traditional direct hydraulic running tool system is that the LCIS utilizes a small OD electric umbilical to multiplex the electric energy to several hydraulic functions subsea. Alternatively, the LCIS can be powered from the ROV auxiliary system, meaning that the system will be entirely operated without use of dedicated umbilical.

Core values in the LCIS design is flexibility, the system can be configured to accommodate various tests and operations – including P&A.

Umbilical-less Tubing Hanger (ROCS)

ROCS- Remote Operated Completion System
Umbilical-less running of tubing hangers
The main purpose of this technology solution is to eliminate the need for umbilical inside marine riser during installation and retrieval of tubing hangers. It is a well known problem in the industry that use of umbilicals inside marine risers is very challenging. Damage umbilicals and dropped objects have resulted in excessive operational cost for offshore operations over the years. Optime Subsea Services has a solution that runs the riser string without use of any umbilical. ROCS can be controlled from the LCIS system or ROV. The ROCS includes electric and hydraulic power mounted on a riser joint. ROCS will be connected to THRA and located above BOP. Communication will be performed via an innovative solution through BOP (patent pending).
Challenges as dirty fluid from tubing hanger tool, seal test lines, contingency/backup, redundancy, volume control, DIACS control are all addressed in a elegant way. Although ROCS solves complex problems, the solution in itself is quite simple and the main focus during the design phase has been robustness. ROCS is mainly based on field proven components packed in a smart way.
Optime will in near future start building prototype and start testing. We have big expectations for the ROCS system and have great faith that this system will change the premisses for how to install tubing hangers in the future. ROCS is designed for 3000 meters and we consider the system to be best way of running your completion, regardless of water depth.
CAPEX/OPEX reduction for operators is the key element in the ROCS solution.

Riser Less and Rig Less Plug & Abandonment

By combining two field proven operational technologies, we have developed an industry unique and first of its kind, completely rig less, riser less P&A system. The system and service allows for

  • Direct well access
  • Efficient run in and out of the well
  • Only a 45 tons – low wellhead fatigue
  • DP vessel on shallow water – increased watch circle
  • Complete operational and reservoir planning
  • Provides the modularity to offer P&A mode and a traditional LWI lubricator mode

Through a large number of FEED studies we have confirmed the ability to complete a permanent P&A, without the use of a rig, at a 60% cost savings compared to today’s rig / LWI solutions.

multiCompletionSystem™

Optime Subsea Services has developed a new service platform offering cost efficient completion operation and light intervention – from lighter and smaller IMR/FSV vessels. This solution can be operated on any type of subsea Xmas Tree. We call it multiCompletionSystem™, mCS.

mCS avoids mobilization of heavy duty Workover System and XT on rig, but rather increase vessel of opportunity. A complete solution allows for umbilical less Tubing Hanger installation (ROCS) and XT completion with production start-up from IMR vessel (LCIS). Later, mCS is well prepared for re-competion and P&A operations, by utilizing more cost-effective vessels. As such, deep water challenges are carefully considered by this innovative solution.
