Tensioner is made up by 6 parts: Top actuating device, bottom actuating device, foundation, guide frame, hydraulic control system and electric control system. The equipment is mainly composed by welded steel structures on which other subassemblies are installed. 4 tracks constrained to the main structure driven by AC electrical motors or hydraulic motors and clamping the pipe and allowing, by friction, to keep the pipe line.
The Tensioner has the main function to apply to the pipes the required tension load, allowing to lay the product spooled out from fixed or portable carousels, baskets or driven reels (storage device) up to the maximum reachable speed. Tensioner is installed in middle or tail part of vessel to clamp pipelines with different diameters and then deliver pipes under the sea through conveyor system. Through the whole pipe welding process, tensioner keeps a constant tension onto pipes. It means that, when the vessel moves, tensioner can deliver pipes to seabed with constant tension to eliminate the influence of vessel moving or sea wave reciprocating. The control system of this kind of tensioner is auto controlled. We already manufactured 2T and 25T tensioner that attested in projects, and we can also design and manufacture for specific demands.
Anhui Jantle Marine Engineering Co. Ltd. (AHJT) is an Integrated Chinese Maritime Engineering and Project Management company offering turnkey solution to international clients keen to take advantage of very competitive prices while maintaining the highest quality standard in the conventional marine vessel and OSV market.

In addition to Jantle Marine in-house capability and deliverables, the company is fully supported by five other medium and large scale shipyards in China bringing the total number of manpower under employment to 4000 proud to have built and successfully delivered any and all types of marine vessels including but not limited to Deck Cargo Barge, Tugboat, AHT & AHTS, PSV, ROV, Pipe-laying Ship, Accommodation/Crane Work Barge, DP3 capability, Product Tanker, General Cargo Ship, Semisubmersible Drilling Rig, Jack Up Rig, Drill Ship, FRP Ferry boat, Patrol boat, FPSO, FSO, LNG, LPG and Bulk Cement Carrier.
Cable laying machine also called mini clamper which is used in marine pipe laying project to deliver cable or tube from vessel ship to seabed. Same as clamper, cable laying machine can deliver cable with constant stress automatically. Cable laying machine is made up by 7 parts: Top driving device, bottom driving device, bottom tank, upright, beam, hydraulic control system and electric control system.
Control
Electric cabinet and hydraulic system are all installed onto the machine. Tension and stress are all displayed through pressure gage that measured by sensor. Hydraulic system has unloading gear to make sure the system keeps unloading during long time cable laying with constant stress. As a result, all the system can save power. We also design a sensor on transmission shaft to display the length already pushed/pulled of the cable.
| Type | Working stress (KN) | Diameter range (mm) | Working speed (m/min) | Working pressure (Mpa) | Power (kw) |
| 2T | 20 | 60~220 | 0~8 | 4 | |
| 5T | 50 | 60~220 | 0~10 | 8 | |
| 10T | 100 | 60~300 | 0~10 | 16 | 22 |
| 15T | 150 | 60~300 | 0~10 | 16 | 37 |
| 25T | 250 | 60~300 | 0~10 | 60 |
