Subsea Plough

The Seabed Cable & Pipeline Burying Plough is capable of burying optical fibres, cables, umbilicals, and flexible pipelines to a maximum 5.5m depth in 650 metres depth with its high-strength chassis. With the adjustable high flow high-pressure jetting system and the skid landing on the seabed, it is towed by the mother vessel to perform laying-and-burying integrated operation. Skids are available with different sizes, or fitted with buoyancy, to meet target seabed condition. The towing-and-lifting integration design requires only one crane for mother vessel to tow and lift.

Sealien is a deep-sea work-class ROV manufacturer with world’s leading technology. We offer a series of services such as solutions on development and delivery of large intelligent subsea cable and pipeline burying trencher, entire trencher system leasing, development and supply of key systems and components, operation, maintenance, and engineering support.


Functional Features
Transportation & Installation
Transportation & Installation
Highly modular design enables quick assembly/disassembling of chassis, track system, jetting system, chain cut module, buoyancy, main lift point, etc., standard with assembling/disassembling tools. All system can be fitted into standard containers, allowing for higher transportation efficiency.
Performance Upgrade
Performance Upgrade
Jetting mode and chain cutting mode are interchangeable to adapt to various challenging geological conditions. Track can be adjusted to multiple DoF to adapt to complex submarine terrains. Travelling mechanism can be changed to achieve different travelling modes for greater operating efficiency.
