Subsea Connection System—Indispensable Part of the Offshore Oil & Gas Field

Sunkye HTHP Connector with the high performance of durability, reliability, and longevity is ideal solution for subsea interconnection systems

What is a subsea connection system?

Subsea connection systems are ROV-operated horizontal and vertical tie-in connections, connecting rigid or flexible flow lines, pipelines, and jumpers with subsea piping modules such as wells, manifolds, in-line tees, and riser bases. This system is used in the offshore oil and gas field.

It is reported that, at the end of 2021, there were 201 offshore rigs in the world. In 2021, there was a notable increase in the global rig fleet as oil demand increased again following the coronavirus pandemic-induced economic slump. Meanwhile, the decline in offshore rigs is mainly due to a fall in proved reserves in the North Sea. The annual average number of global oil rigs that year was 1,361, only a slight increase compared to 2020.

Subsea oil fields are operated by a large number of connections between various kinds of subsea equipment. Generally, Subsea connection systems include Flowline Connection Systems, Horizontal Connection Systems, Vertical Connection Systems, Pipeline Terminations, Manifolds, Jumper Systems, etc. And Now HPHT connector systems are one of the industry’s greatest challenges.

These connections of subsea systems need to be safe and reliable as connection problems can cause a series of problems in operating subsea equipment. On top of that subsea connection, failures may also cause oil spills or gas leakage in the environment. This requires the parts of the subsea connection system a high sealing performance.

Sunkye HTHP electrical connectors are designed to support the signal transmission of high voltage ratings, which is a type of glass sintering adapter with a single contact. Sunkye’s HTHP electrical connectors are used for oil & gas fields with the high performance of high density, light, and highly reliable, and the air leakage rate is 1x10-3Pa.cm3/s.
