Underwater pipeline
Pipelay control system
Calculated parameters:
- Pipe internal pressure distribution
- Stress distribution and pipe geometry
- Water depth at the bottom contact point
- Air balance pressure & compression curves
- Pump, compressor and air vent performance
On pipe end
Monitor air pressure, pulling force and
depth of pipe end when it sinks underwater.
Remote control air vent & compressor inlet valves.
Onshore
Monitor pipe & pumps pressure
Remote control pumps throttle & pipe went valves
S-lay analysis software
Control panels
Applications:
- Pipelay simulation
- Pipelay monitoring & control
- Pipelay at unknown bottom profile
Features: Do not require previous knowledge of the “S” lay calculation method.
All pipelay parameters calculated and displayed at one place – no need to switch between multiple programs.
Results displayed numerically and graphically, full situation awareness at a glance.
Models C1 & C2
Pipeline anchors - casting
Anchor molding machine
Interchangeable molds
custom size and shape
Mold lifting frame
C1 - anchors for pipe up to 300 mm (12") diameter
C2 - anchors for pipe up to 600 mm (24") diameter
Cc - for pipe over 600 mm (12") custom order
Anchor molding machine enables quick pipeline anchors casting.
Suitable for casting in a workshop or at the site of opportunity.
Requires very small area and few persons to operate.
Interchangeable molds enable casting different shape and size
anchors.

Features:
- require small area
- quick casting ~5 minutes per anchor (for 300 mm pipe)
- casting possible at the site or very near to reduce transport costs
- 1 person at mold, 2-3 persons to prepare and deliver concrete
- easy to transport, quick mobilization
Pipeline anchors - assembly
Pipe pulling machine
Model P1
up to 300 mm (12") pipe dia.
hydraulic or electric drive
Pipe pulling machine
Models: P2 / P3
P2 - 250 mm (10") - 400 mm (16")
P3 - 400 mm (16") - 600 mm (24")
Pc - over 600 mm (24") custom order
± 20° pan & tilt / hydraulic drive
All models:
forward / reverse
inflatable tires to adjust the proper cushion for different pipe size and weight
System features:
- quick assembly, ~3 minutes per anchor (300 mm pipe)
- require small assembly area on barge or onshore
- easy to transport, quick mobilization
Pipe pulling machine and anchor clamps enable very fast anchor assembly, on average ~ 3 minutes per anchor (300 mm pipe). Require two persons to position and fasten anchor, and adequate crew to supply anchors. Assembly can be from barge or adequate place onshore. It is very useful for assembly in an open, unprotected area, possibly near a sinking site to shorten towing time, lower cost and risk of bad weather.

Anchor clamps
Custom size, stroke and clamping force pneumatic or hydraulic powered
Applying clamps, crane is released before screws are inserted and tightened thus speeding up crane turnover time

Socket & Keylock
joint assembly
HV 1
HV 2
Key Lock
rod pusher
HV 1 & HV 2 vices are designed for underwater GRP, PVC, STEEL and CONCRETE pipes assembly.
In a cumbersome underwater environment, HV 1 & 2 provide fast assembly/disassembly of socket joints.
When fitted with Key Lock rod pusher, enable quick completion of all Key Lock joint types.
Vice can handle any 3 standard, sequential pipe diameters. This is achieved by 2 sets of inserts to reduce clamping diameter. Vices are custom made for user-specified pipe diameters.
Both models are neutrally buoyant. HV 1 has inflatable floats to increase/decrease buoyancy.
HV 2 is set to neutral buoyancy by rigid buoyant inserts.
Operational depth - diver limits, or custom specified.
Benefits: Reduce dive and support team size. Significantly shorten assembly time and reduce overall costs.
Key Lock rod pusher
Rod pusher addon for fast Key Lock rod insertion.
Pushers are hydraulic or mechanical (impact).
Custom made for different rod size, length, and shape
