Gisma Connectors

Proud Gisma Partners for Over 20 Years


Scientific Management International have been the UK partners of subsea connector specialists Gisma for more than two decades.

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 22 Subsea Connectors

Series 22 connector from GismaScientific 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.

Key Features

• Watertight at high pressure
• Dry mating capability
• Lip, conical and o-ring sealing in the mating area
• Elastomer insulator with conical insulation barrier increase
• 1 to 265 contacts
• Operating voltage up to max. 3,2 kV
• Operating current up to max. 400 A
• Test pressure up to 400 bar
• Open face pressure watertight
• Pressure hull penetrators material 1.4404 or 1.3964 standard

 

Series 10 Connectors

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.

Key Features

• Open face pressure watertight
• Watertight at high pressure.
• Lip and conical sealing in the mating area
• Operating voltage max 6.6kV
• Operating current up to 1,000A
• Test pressure up to 880 bar
• Contact arrangements 3 to 61 contacts

 

Series 16

Gisma Series 16 ConnectorThe 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.

Key Features

• Made for rear-side oil pressure
• O-ring, lip and conical sealing in the mating area
• Standard contact arrangements from 7 up to 55 contacts
test pressure up to 600 bar
• Operating voltage up to 300 V
• Operating current max. 15 A
• Robust keyway

 

Series 40

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.

Key Features

• Available in bronze, titanium and stainless steel
• High pressure watertightness
• Double o-ring sealing in the mating area
• Dry mating capability
• Contact arrangements 1 to 24 contacts
• Fibre optic contacts for single mode and multimode
• Open face longitudinally watertight
• Electrical contacts 630 V / 25 A
• Electrical contacts 1000 V / 8 A
• Test pressure up to 600 bar

 

Series 80

Series 80 connectorThese 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.

Key Features

• Underwater mating capability
• Oil filled and pressure compensated
• 25 years design lifetime
• High pressure watertightness
• Excellent insulation values
• Test pressure up to 600 bar
• Double o-ring-sealing
• Contact arrangements 1 to 19 contacts
• Push-pull locking system
