Seadrift Offshore (Seadrift) delivers simple to maintain and operate tether management systems (TMS) and launch and recovery systems (LARS) for the offshore industry.
Launch and recovery systems for oil and gas applications
Seadrift designs a series of LARS systems using the most durable and cost-effective materials.
Designed and built according to DNV standard 2.22 for lifting appliances, they are reliable, safe, and easy to construct / operate, and need minimal maintenance in the field.
The company’s standard Goliath LARS systems are also available with bespoke components upon the client’s request, such as larger working envelopes, passive damping and complemented with construction and survey modes.
Tether management systems (TMS)
Seadrift specialises in the design, manufacture, supply and service of ‘Top Hat’ TMS, which are built to be safe, reliable and simple to operate.
The company’s standard TMS includes:
- 6000 Work Class Maverick 1
- 6001 Work Class Maverick 11
- 6005 Work Class Massimino
- 6015 Work Class Massimo
- 6300 Rig Support Mantis
Seadrift’s TMS designs have also been developed to provide longer excursions distances and become increasingly compact.
The twin-latching system enables safe operational control during tether launch and recovery, and all parts are easy to install and maintain.
Each design incorporates a constant tension system and a unique, fleeting vertical-to-horizontal sheave system (VHSS), which extends tether life and enables long-term cable recovery.
Emergency recovery tools (ERT)
Seadrift supplies a range of operator-controlled and fail-safe systems, which can be easily deployed to safely recover a remotely operated vehicle (ROV) and TMS and are manufactured in conjunction with any design of termination socket.
They are simple-to-install and are produced from 316L stainless-steel. Other materials are available on request.
Umbilical termination sockets (UTS)
Made from fully machined billet, Seadrift’s range of 17-4-PH robust termination sockets ensure integrity and longevity in adverse offshore environments.
Umbilical testing facility (UTF)
Seadrift accurately measures and records umbilical breaking forces and elongation using portable, programmable logic controller (PLC) operated tensile test equipment for safe and consistent results.
The company safely and consistently measures the cable elongation and breaking force via a hard-wired pendant. Data is automatically retained and can be exported to assist clients to help determine the lifespan of an umbilical, enabling the scheduling of global operations.
The software creates a performance history database, which supplies details on cable life.
The 100Te SWL 20 container has a diesel generator to provide power in remote locations and can be used on a variety of umbilical sizes.
