SoluForce marginal field offshore

Making marginal offshore fields economically viable


Flexible subsea pipeline & riser systems for high-pressure offshore oil & gas

When it comes to making marginal offshore oil and gas fields economically viable, SoluForce subsea pipeline solutions offer several advantages over steel and other flexible options.

Why use SoluForce flexible pipe system?

Our pipeline and offshore riser systems are light, strong, durable, and reliable — with shorter lead times– perfect for connecting low-viability wells to nearby platforms, eliminating the need for a new drilling platform. Our pipes are faster, easier, and cheaper to deploy with no welding required, plus there's no need for hot permits or specialist pipe-laying barges.

SoluForce flexible pipe system propeties

SoluForce pipeline systems are entirely corrosion resistant even in extreme sour service. Our pipes have a smooth bore, ensuring a much lower flow resistance and improved flow capacity. SoluForce pipes can be used unfilled at a maximum depth of 80 meters/260 feet, or when filled, can be used in much deeper water, where they have acted as temporary test lines at depths of 1000 meters/3280 feet.

All SoluForce flexible composite pipeline systems use metal-free fittings, couplings, and connectors. Our pipeline systems are therefore resistant to all chemicals involved in various applications, including:

  • H2S
  • CO2
  • Strong inorganic acids like HCl and H2SO4
  • Strong alkaline materials, including NaOH, KOH, and NH2 solutions
  • Anti-corrosion additives
  • Mineral salts

Typical offshore applications of the SoluForce system includes:

  • High-pressure water injection lines
  • Oil and gas transportation flow lines
  • Gas and oil gathering lines
  • Well intervention
  • Landing/ export lines

SoluForce pipes are stabilised on the seabed using locally manufactured steel or concrete blocks. These blocks are easy to handle and manufacture, and make sure that the SoluForce pipe is securely anchored on the seabed. For example, an old steel cable can also be used to stabilise them on the seabed.

Pipe Types

SoluForce Flexible Composite Pipe (FCP, also known as Reinforced Thermoplastic Pipe or RTP) solutions are comprehensive yet economical. Especially in the offshore market where costs can rise quickly, SoluForce has proven itself as the go to solution for quick and economical deployment of long lenght pipelines. In most cases preparation can be done onshore, minimizing valuable offshore time and leading to unbeatable installation speeds. When selecting SoluForce for your project, you can opt for pipes-and-fittings only or extend this with a wide range of services and support.

Our services include installation equipment for rent or purchase and training international and local workforces to use the SoluForce system — all so you can safely speed up installation and reduce your labor needs. We can also assist with project management and help you find the right people for your project. Or any combination of the above.

Because the SoluForce system can be completely non-metallic, they are both scaling and corrosion free. All SoluForce pipe systems have a smooth bore, ensuring a much lower flow resistance and improved flow capacity. Moreover, their resistance to dynamic operations has been extensively proven and verified, making them ideal in subsea pipeline scenarios.

All SoluForce solutions comply with international standards (including API and ISO). Visit our track record page for more information on various SoluForce applications.

SoluForce Heavy ST 3D Render


Reinforced with high-strength steel wire, SoluForce Heavy has a Pburst,min ranging from 243 bar/ 3524 psi up to 450 bar/ 6527 psi. The GT (Gas Tight) version has the added benefit of being non-permeable, and the HT (Hight Temperature) version can transport fluids at temperatures of up to 105°C/225ºF – a level of performance unmatched by any other flexible composite pipe available today.

SoluForce 3D Render Heavy HT

High Temperature (HT)

Our SoluForce Heavy HT has a design temperature of 105°C/ 225ºF and actual operating temperature of 85°C/ 185°F – a level of performance unmatched by any other Flexible Composite Pipe (or RTP) available today.

SoluForce Heavy GT 3D Render

Gas Tight (GT)

With a uniquely manufactured bonded aluminum layer, light components and gasses are not able to permeate out of the SoluForce GT pipe. Resulting in the industries only completely Gas Tight Flexible Composite Pipe (or RTP) system. 

SoluForce Fitting Solutions

The SoluForce system includes a variaty of fitting systems catered to offshore applications. All fitting systems are extensively tested, certified and have proven themselves in (dynamic) offshore applications. With the electrofusion and single swage fitting solutions, the fluids or gasses never come into contact with the metal parts of the fitting system by using a non-metallic insert. This results in a completely corrosion and scaling-free system, no matter what fluid or gas is transported through them.

For pressures higher than 150 bar/ 2175 psi, the double swage fitting is the system of choice. All fittings can be disconnected easily to allow for easy relocation of the pipeline.

Multiple flange ratings are available. All steel parts can be produced according to your material specifications.

SoluForce 3D Render Electro Fusion end fitting

Electrofusion fittings

The non-metallic fittings and connectors used with the SoluForce Light, Classic and Heavy systems rely on electrofusion. Electrofusion requires only limited equimpent and crew to create a safe connection. It's quick and proven to be maintenance-free and durable.

SoluForce 3D Render Single Swage end fitting with insert

Single swage fittings

For onshore high pressure applications our single swaged fitting system, with non-metallic lining, is the fitting system of choice. The single swage system is fully corrosion free and combines strength with cost effectiveness.

SoluForce 3D Render Double Swage end fitting

Double swage fittings

For high performance and offshore operations, SoluForce offers heavy duty double swaged fitting system. This fitting system is optimised for extremly high pressures, high axial loads and dynamic operation. It's available as standard with Grayloc connections, but weld stub and other user-specific connections are possible.

Frequently Asked Questions

Aside from the fact that steel corrodes when exposed to salt water, the industry is now trying to extend recovery rates from old oil fields to keep them productive for longer, which necessitates the use of water injection (among other methods). Though this technique can make marginal oil fields more productive, it also makes hydrocarbons more sour, leading to higher corrosion rates over time.

For corrosion inhibiting chemicals to be effective, pumping systems need an uptime of over 90%. Not only is this rarely achievable by the majority of operators, but the process also requires a constant supply of chemicals and the heavy use of pumping systems.

Before steel pipes can be laid, a pipe laying barge needs to be mobilized, which may necessitate a lengthy relocation from another region. In contrast, SoluForce pipes come in long, spoolable lengths, which makes them simple and cost-effective to lay, with a low weight that can easily be tolerated by smaller vessels. Moreover, installation can be prepared onshore, leading to daily installation rates far exceeding possibilities of steel pipelines.

An offshore riser system is a type of subsea pipeline that runs in a vertical orientation, and is used to carry materials to or from the seafloor to semi-submersible drilling rigs or production facilities. There are many types of riser design, from marine drilling risers to export pipelines for oil and gas production. Marine risers can either be flexible or rigid, and are often insulated for use at extreme offshore water depths.
