Rental Equipment

J+S has a range of equipment available to rent for on and offshore purposes. If we do not have required items in our own stock, we have identified and work with selected vendors and partners in order to provide timely solutions.

Subsea System Analysis & Data Monitoring Equipment

  • Supply Voltage: 9-28Vdc
  • Maximum Input Current: 100mA
  • Scaling Rang - Span: 0-2000

J+S is developing a range of monitoring equipment to provide our clients with solutions to identify subsea issues. This range of basic tools are designed to assist intervention operations by providing immediate and local display of sensor outputs or basic system parameters. This range is adaptable to allow connection to any system and standard port interfaces enable the option of penetrators to cable or oil filled hose assemblies either side for ease of installation. This range can also be expanded to meet any new requirements identified.

Display 420

The Display 420 is a basic display which provides local indication of a 4-20mA signal. Designed for installation and retrieval by diver, the display is loop powered so there is no need to provide a separate power supply or battery.

Display Specification

  • Supply Voltage: 9-28Vdc
  • Maximum Input Current: 100mA
  • Scaling Rang - Span: 0-2000
  • Scaling Range - Offset: -1999 - 1999
  • Storage Temperature: 0 - 60 ⁰C
  • Operating Temperature: 0 - 60 ⁰C
  • Maximum Voltage Drop: 3.2Vdc
  • Equivalent Resistance: 800Ω Max @ 4mA, 160Ω Max @ 20mA
  • Display: 3 ½ digit 0.6”
  • Sensor Display: Pre-set to 0-100%, 4-20mA or sensor range

Display DV

The Display VA is a subsea In-line Voltage & Current display. This will provide a local indication of Voltage and Current. The unit can also be installed directly onto the end of a test downline enabling Divers to see directly whether the line is powered during intervention operations.

Simulator 420

The Simulator 420 utilises the same simple 0-100% display but with the addition of a loop powered 4-20mA simulator and rotary switch. This is designed to be connected between the Subsea Control Module (SCM) and the sensor. It is then used to either display the output signal from the sensor output or inject a set range of simulation signals to test the SCM’s operation.

Simulator Specification:

  • Supply Voltage: 12-28Vdc
  • Output Range: 9-28Vdc
  • Fixed Pre-set: 9-28Vdc
  • Output Accuracy: +/- 1% of full scale @ 25⁰C
  • Protection: Reverse Polarity
  • Load Range: 0-1000 Ω (250 Ω typical)

Data 420 / DataCAN

The Data420 or DataCAN are subsea In-line data loggers that include a retrievable data memory module recording 4-20mA or CANBus data. This unit can be left connected in-line and the memory module retrieved and replaced when required.

Test Equipment

J+S have a range of test equipment available to rent for on and offshore purposes. All our test equipment comes with valid calibration certificates and our trained technicians are available to provide operating and analysis support. We have identified and work with selected vendors and partners to provide additional specialist test equipment if required.

Our test equipment capabilities include but are not limited to:

  • Insulation Resistance (IR)
  • Continuity Resistance (CR)
  • Time Domain Reflectometry SX-1
  • Kikusui PCR4000M AC Power Supply
  • Hydraulic Test and Flushing
  • Cleanliness Monitoring

Downlines

J+S have a range of stock downlines available that can be terminated with client specific connections for offshore use. Our trained technicians will prepare and deliver these downlines on fully certified Reeler units and provide support offshore for deployment and testing.

We also have a range of ancillary equipment to go with our downlines including but not limited to:

  • Subsea Electrical Test Whips
  • Deck cables
  • Workshop Containers
  • Air hoses for reelers
  • Sheaves for deployment
  • Test equipment

Connectors

J+S have a range of electrical connectors and hydraulic couplers available to rent for on and offshore purposes. Our trained technicians can prepare and certify equipment for use as test connectors, interface components for FAT’s, long term protective caps and end caps with wired loop properties.

Phil Reid

Managing Director

Phil has worked in the energy industry for over 25 years. He started his career with Kvaerner FSSL progressing through a variety of roles in subsea engineering, from manufacturing to leading some of their most complex projects all over the world. He worked with the original J+S for a period before moving on to Genesis Oil and Gas as a Subsea Controls Engineering consultant; during that period, he was seconded to Centrica Energy (now Spirit Energy) which led to a permanent role as Lead Subsea Controls & Umbilical Engineer for Developments, Capital Projects and Operated Assets. For almost a decade Phil successfully delivered Capital Projects from concept right through to project close out whilst also looking after the running of their subsea assets.

As part of J&S Subsea limited, Phil oversees the day-to-day operations and will grow the business both in the UK and globally. 

James Morris

Engineering Director

James’s career started when he joined the Royal Navy from school as an Artificer Apprentice. After a 5-year Marine Engineering Apprenticeship he served in surface ships HMS Glamorgan, HMS Edinburgh, and HMS Glasgow and at Rosyth as part of an engineering support team. 

Moving into the Energy Industry in 1992, over the next 26 years he gained a wealth of experience within large and small companies on operation, design and project management of subsea control systems and equipment. This period started with several years as a Project Engineer for a family run hydraulic services company Grampian Hydraulics followed by 5 years as a Support Engineer at Kvaerner Oilfield Products.  James joined RRC Controls Services ltd in 2001 before finally moving to J+S Ltd in 2010. At J+S his dedication and technical capabilities were rewarded with several promotions until becoming a member of the management buyout team. 

He has designed an extensive array of subsea equipment from basic cable penetrators to complete subsea control modules. 

James thrives on providing solutions for client’s problems. 

As Engineering Director, James will ensure that the company provides clients with timely, cost effective and technically sound solutions and services. 

Matthew Blair

Executive Chairman

Matt Blair is Executive Chairman of J+S Subsea which was formed in October 2020 through a management buyout of the Subsea Engineering Division of Systems Engineering and Assessment Ltd.

With J+S Subsea and SEA for over 14 years, Matt has a wealth of industry knowledge and expertise.

Previously an Electronics Engineer with Ferranti Computer Systems Ltd specializing in sonar and submarine command systems, Matt moved into hydrographic survey working with Subsea7, Tritech, and CDL before joining J+S Subsea.

He was Vice Chair of the Decom Leadership Group of Decommission and in that role, he facilitated industry and academic studies on potential for reuse and repurposing of decommissioned equipment. He is still actively involved with the reuse agenda through Decommission and OEUK.

Although not part of day-to-day operations, Matt stays close to company strategic matters and is seeking further opportunities to update and transfer Energy technologies and products into the Marine Renewables markets and help to develop the broader circular economy.
