Flexible Engineered Solutions (FES) International

Fluid Transfer Solutions

FES International can also provide installation, commissioning and support specialists to the client on site.

With more than 40 years’ experience, FES International has a proven track record in the design, manufacture and supply of products for the oil, gas and offshore renewable energy markets.

The company combines technical innovation with excellent customer service, delivering safe, efficient and cost-effective solutions, tailored to meet customer demands and market needs.

Experts in engineering, the company employs highly-qualified technical personnel, at their Blyth facility, across all areas of a project, from design; including FEA analysis and modelling, draughting (on the latest 3D software), machining and manufacture and assembly and testing.

FES International can also provide installation, commissioning and support specialists to the client on site. Even after a project is operational, our team is always available to the client for assistance and support, ensuring the best service and best quality at all times.

In doing so the company is committed to delivering a quality engineered solution on time and in the most cost-effective way possible.

Our products

  • Disconnectable fluid transfer system (DTS)
  • Fluid swivels
  • Hydraulic-electric stab plates
  • Diverless bend stiffener connector (DBSC)
  • ROV hot stabs
  • Pressure balanced weak link couplings (PBWL)

Disconnectable fluid transfer system (DTS)

FES International designs, manufactures and supplies a broad range of fluid transfer systems.

In particular, the FES team has devised a unique disconnectable transfer system (DTS) that can be installed to a dynamically positioned (DP) or moored FPSO, either as a new build or retrospectively fitted to an existing vessel.

The system enables the simultaneous transfer of fluids from subsea wellheads to the vessel, with automated connection and disconnection built-in, removing the need for manual intervention.

Critically, FES International systems can be disconnected within 40 seconds in the event of an emergency or drive-off scenario.

Other systems the company can supply include:

  • Reeling systems
  • Bow loading systems
  • Skid mounted systems
  • LNG and LPG transfer systems
  • Stern off take systems
  • Hose breakaway systems

Fluid swivels

FES International can provide customers with a whole range of swivel systems, including production, gas, hydraulic and utility, chemical injection, single, in-line and multipath designs.

Our swivel systems have been developed to operate among high pressure ranges and can function from zero to 10,000 psi.

The product offers a multiple sealing system, including leak detection, and can operate with a diverse range of fluids.

Hydraulic-electric stab plates

FES International offers customers a choice of stab plates with hydraulic and electrical connections.

The company designs bespoke stab plates, meeting clients’ individual specifications. Specifically, we have developed our own automatic disconnection system, which enables quick release disconnections from only 15 seconds, significantly improving on existing disconnection speeds available with other products on the market.

Customers are also offered the following options on bespoke orders:

  • A choice of coupling materials, fluid sealing and composition designs
  • A range of design pressures from 0-15,000 psi
  • Variety of coupling sizes, from a quarter-of-an inch to two inches
  • Low and high voltage electrical connections
  • Fibre optic connection

Diverless bend stiffener connector (DBSC)

FES International offers customers a range of DBSCs, enabling quick, efficient and cost-effective installation of bend stiffeners to I / J tubes, often in very congested and confined spaces.

The FES DBSC is a flexible design that can be tailored to suit the specific and individual requirements of both the project and end user, for particularly challenging projects from technical, commercial and delivery perspectives.

Customers are also offered the following options on bespoke orders:

  • A choice of end fitting / pull in head release mechanisms
  • Full strength and weak link systems
  • Automatic to connect systems
  • Comprehensive test programme including simulated pull in test (SIT)

ROV hot stabs

FES International can provide ROV hot stabs in a variety of materials designed to suit project requirements.

Our range includes a proprietary design of hot stabs, ranging from half of-an-inch to eight inches in size, and the standard API 17D/17H/ ISO 13628-8 models.

For sizes of four inches and greater, where the insertion forces are higher, we have developed a unique, hydraulically-operated hot stab, which enables the quick and safe transfer of fluids, without the need for a diver / ROV to provide the insertion / retraction forces.

The product incorporates a dual seal system and can operate at pressure ranges of zero to 15,000 psi.

Pressure balanced weak link couplings (PBWL)

FES International designs, manufactures and supplies a broad range of PBWL couplings.

Ranging in size up to 12 inch bore, the product operates in pressures of zero to 10,000 psi with a break load of up to ten Te.

An optional internal valving system also ensures minimal fluid loss on disconnection.

Company profile

FES International was established in 1997 in Blyth, Northumberland, UK.

Placing technical innovation and customer service at the heart of the business, FES International has developed a first-class reputation for the deployment of fluid transfer solutions to the oil and gas sector.
