Scientific Management International have been proud partners with Gisma for over the past 20 years. That’s more than two decades of being UK partners of subsea connector specialists.

In this time, both companies have continually innovated and developed new solutions for the most hostile of connectivity environments. Gisma’s expertise in developing underwater connectors, specifically designed for wet underwater plug-in and demanding operating conditions, is perfectly aligned with our own goals of producing robust, high quality, pressure moulded subsea cable systems.

Wet Mating & Dry Mating Solutions from Gisma


Series 10 Connectors

Gisma Series 10 Connector

These electrical round connectors are available in bronze, stainless steel and titanium and are designed for hostile environments. They are commonly used for oil & gas, defence and renewable energy applications where operational reliability is paramount. The patented lip seal guarantee of the watertight vulcanized elastomer insulators help to deliver such reliability and the optional gasket in the mating area enables increases in long term performance for various applications.


Series 16 Connectors

Gisma Series 16 Connector

The dry Series 16 connectors are specially designed for long-term use and are fitted with the proven insulator principle of Series 10. The longitudinally tight seal on the connection side of these connectors make them particularly suitable for a hose connection system and are often applied in this way in offshore industry and renewable energy applications. As with all Gisma connectors, the Series 16 delivers high operational reliability and are watertight up to 450 bar of open face pressure.


Series 22 Subsea Connectors

Gisma Series 22 Connector

Scientific Management International have exclusive rights to this series of electrical and hybrid connectors. They are designed for long-term underwater applications such as naval technology, renewable energy and specific industry applications. The patented lip seal combined with the longitudinally water tight vulcanised elastomer provides a high level of operational reliability. Added to this, the additional gasket in the mating area also helps ensure the long-term performance and the metric locking thread in the cap nut enables secure locking.


Series 24 Connectors

Gisma Series 24 Connector

The Series 24 connectors are suitable for smaller design dimensions and ensure a strong technology connection with a variety of applications. These connectors provide an ideal solution to harsh environments as they are made with seawater and corrosion resistant bronze metal shells. The Series 24 connectors have a range of design and technical features that make them ideal for watertight installation.


Series 40 Connectors

The Series 40 possess a robust design that was developed for long-term underwater applications, such as in naval technology. The double o-ring seal in the mating area helps to deliver this longevity in the most hostile of environments and the metric locking thread in the locking sleeve allows secure locking. High quality PC optical fibre inserts ensure secure data transmission and different hybrid contact arrangements can be achieved thanks to the modular contact inlay which can be fitted on any contact space with electrical contacts. SMI can also provide our SlipStream range of mouldings which offer a low profile 90° cable exit whilst protecting the optical fibres and managing the minimum bend radii.


Series 80 Connectors

Gisma Series 80 Connector

These push-pull connectors are predominantly used in ROV applications, subsea stab plates and junction boxes. Thanks to the flushing device in the oil-filled mating area a high insulation value is guaranteed after underwater mating. As these connectors have an oil-filled plug they are pressure compensated and offer constant mating forces regardless of water depth.
