Subsea
From subsea mooring to buoyancy, Trelleborg Offshore boasts an extensive range of innovative solutions serving the subsea sector.
Bend Control Solutions
Where any flexible tubular connects to a structure, normal movement during operation or forces incurred during installation can cause catastrophic failure of the tubular at the termination point. Our Bend control solutions reduce this damage.
Buoyancy
In floating production scenarios, pipelines such as flexible risers, cables and umbilicals are often required to be held subsea in specific geometric configurations designed to prevent over utilization of the system
Cable and Flowline Protection
With an ever increasing global requirement for data and product transfer, and the necessity for transfer networks to run through ever harsher environments, the demand for highly advanced cable and flowline protection grows
Clamping Solutions
A pipeline laying operation may have a requirement to simultaneously lay a small diameter service line or umbilical. During the installation, to ensure that the secondary lines are adequately supported between surface and seabed, they may be attached to the main pipeline using a clamp arrangement.
ROV/AUV/HOV Buoyancy systems
ROV/AUV/HOV Buoyancy systems are being used in deeper water depths, the need for low density materials which enables a high buoyancy with reduced volumes, makes it ideal for inclusions with the frame structure of these vehicles.
Thermal Insulation
Thermal insulation is necessary to avoid formation of hydrate plugs and wax build-up in subsea structures. The build-up begins when the oil/gas composition temperature is not maintained and begins to cool. Without thermal insulation the cold seawater rapidly cools down the oil, forming hydrate/ wax blockages making it impossible for a safe flow

Deepwater Performance in Brazil
The Petrobras P-58 FPSO, which operates on the Baleia Azul field in the Parque das Baleias area, north of the Campos Basin in Brazil, is moored 48 miles / 78 km offshore in a water depth of 4,593 feet / 1,400 meters, and is expected to last 25 years. Oil production, which commenced in March 2014, comes from 19 satellite wells connected individually to the unit.

A buoyant future for oil & gas exploration in Azerbaijan
Situated in the South Caspian Sea, off the coast of Azerbaijan, the Shah Deniz gas field stands at a depth of 600 meters, covering approximately 860 square kilometers. There is a growing requirement in deepwater applications such as this for flowlines to perform under high temperature and high pressure conditions. Large cyclic changes can cause expansion of the flowline, resulting in lateral or upheaval buckling. At a depth of 600 meters / 1,968 feet below surface, these flowlines will come under significant force.

Raising the solution up a level to deliver water to Cyprus
A pioneering engineering project, the Mediterranean Subsea Water Pipeline will see 75 billion cubic metres of fresh water delivered to Northern Cyprus each year from the Mersin province in southern Turkey.

High level performance for world’s first subsea gas compression facility
Located on the Halten Bank in the Norwegian Sea, about 200 km from mid-Norway, Åsgard is a central hub and a significant oil and gas producer. It is also the first field in the world to use seabed gas compression. The decision to adopt this new technology on the Åsgard field is expected to maintain production and an increased recovery equivalent to approximately 278 million in barrels of oil when the project is realized.
Bespoke flow assurance in Nigeria
Located roughly 60 miles offshore Nigeria, the Erha North phase two development sits at 3,960 feet / 1,200 meters deep and is an extension of the existing Erha subsea system and infrastructure. The existing system is currently producing to the Erha floating production, storage and offloading (FPSO) vessel
