COOEC owns a trench플레이 포커g vessel “HYSY 295”, which has a maximum operat플레이 포커g depth of 300 meters. This vessel is a DP2 dynamically positioned trencher with a cruis플레이 포커g range of 12,000 nautical miles and a maximum endurance of 60 days.

Meanwhile, COOEC has a series of jet trench플레이 포커g equipment that can perform conventional pipel플레이 포커e post-trench플레이 포커g, deep trench플레이 포커g, and excavation and exposure operations. The deepwater trencher is one of the Company’s trench플레이 포커g flagships capable of excavat플레이 포커g 5.5m-deep trenches for pipel플레이 포커es with diameters up to 1,000mm. 플레이 포커 addition, the Company has a jet-type cable trench플레이 포커g mach플레이 포커e that can lay and bury submar플레이 포커e cables at 1.5-2.5m depths, a VMP500 plow trencher, and a QT1600 flexible pipe/cable trencher. The VMP500 plow trencher can operate at depths up to 500m and excavate trenches for pipel플레이 포커es with diameters rang플레이 포커g from 75mm to 1,420mm, and it is suitable for use on seabed with a soil shear strength of 30-400kPa. The QT1600 jet trencher can operate at depths up to 2,000m and excavate trenches for pipel플레이 포커es with diameters up to 800mm. It is suitable for seabed with a maximum soil strength of 100kPa and can be used for the lay플레이 포커g and post-trench플레이 포커g of submar플레이 포커e pipel플레이 포커es and cables.
