- Pressure / flow control
- Pilot on / off control
- Run down check valve
- Reverse flow check valve
- Pressure reducing versions can be coupled together allowing multiple tools to be run from same hyd supply
Specialist Offshore 3 Stage Manifold
The Specialist Offshore Services 3 stage manifold allows the user to select 3 pre-set pressures to a tool or pump. The low rate is set by the user as well, and then using the 3 pressure valves, the user sets the required pressure levels. Can be used on torque tools, as a direction selection is also available, or just run a pump at different pressures as required.
The simple to interface custom drive manifold means that the unit can be used on a wider range of ROV’s, as it allows the user to limit pressures and flows depending on the customers hydraulic supply abilities. Unit is supplied complete with hydraulic hoses, and is very easy to set up for use in field.
- Hydraulic Input max 210bar, 100 LPM
- 3 mutually exclusive outputs, all adjustable 0-210 bar
- Pilot operated valves to select different pressures.
- Flow adjustable from 0-100 LPM
- Operational hoses supplied
- Easy adjustment of cartridges
- Gauge ports on all outputs
- Used to control torgue tools as aDCV is included on the output for both CCW/CW direction
- Used with various pumos to select 3 different pressures
- Measures 400x280x180mm, weight 5kg
Specialist Offshore Pipetracker Retracter Frame
The Specialist Offshore Services pipe-tracker retractor frame / TSS 440 retractor frame design allows an ROV to retract a pipe-tracker to a vertical position. Thus facilitating easier launch and recovery.
The lightweight but robust design ensures the customer that no additional buoyancy is required when operating the TSS 440 ROV mounted frame.
The retractable pipe tracker frame consists of 2 arms, slid into 2 mounting brackets. Those mounting brackets are then mounted on to the side of the ROV. Specialist Offshore Services supplies the TSS 440 retractor frame with a hydraulic control panel. Although, some ROV’s will not require this.
A custom hydraulics control panel synchronises the cylinders. So to ensure that the up and down motion of each side stays level.
The mounting options are varied and easily customised to suit any ROV. The retractor is made for use with the standard acetyl square rod with cross section dimensions 38x51mm, that is usually supplied with the pipe tracker system.
A kit is provided to allow the user to use 50x50mm square cross section glass reinforced plastic (GRP). This does not suffer from bending as much as the standard acetyl rectangular section material which is normally supplied with the pipe tracker systems.
- Weight (each arm) : 32kg in air / 25kg in Sea Water
- Weight hydraulics panel: 4kg in air / 2kg in Sea Water
- Robust design
- Fully retractable for safe ROV deployment and recovery
- Suitable to fit on a range of different ROV’s
- Available for hire

Zetechtics Jupiter Type 1 Subsea Control System
Zetechtics Jupiter Type 1 Subsea Control System
Jupiter Type 1 changed the industry by offering a fresh approach to subsea control. As subsea automation increased, so did the requirements of the control system.
