Offshore in situ reduction technology

Overview:

Offshore in situ reduction technology includes chemical pretreatment, screening- flocculation-filtration, liquid treatment        and utilization and auxiliary equipments. On account of the types of waste and on-site operating conditions, treatment        processes can be customized.

Features:

Enclosed conveying of wastes; In-situ treatment; Minimum waste quantity and disposal costs; Suitable to different water-based        drilling fluid systems; Environmental Protection Solution Vessel (EPSV) option; The liquid after treatment can be        100% reused.

Offshore drilling cuttings convey equipment

Overview:

According to the requirements of the offshore recycling operation mode, integrated solutions such as screw conveyor system        and plunger pump closed transfer system are provided to achieve long distance, high drop, uninterrupted continuous        conveying and collection operations.

Features:

Long conveying distance;

Offshore drying and sorting equipment

Overview:

Through the screening function of the equipment, the larger cuttings are sorted and collected with ton bag, while the        liquid phase with smaller cuttings drop into the under-screen collection tank. The liquid will be transported to        flocculation filter system for further treatment. The technology can reduce the liquid content of drilling cuttings        and achieve the reduction goal.

Features:

Compact mounted; Strong sorting ability; Large capacity; Low water content on cuttings after treatment.

Offshore flocculation filter press equipment

Overview:

Waste water-based drilling fluid is to be flocculated by chemical pretreatment system, and then filtered under pressure        for deep separation. The separated liquid phase is transferred to next process for reuse, and the solid phase is        collected with ton bag. The technology can reduce the waste volume by 80%.

Features:

In-situ treatment; Minimum waste quantity and disposal costs; Suitable to different water-based drilling fluid systems;        The liquid after treatment can be 100% reused.

Multi-stage reduction equipment    Overview:

With the research and development concept of "gravity filtration separation+flocculation centrifugal solid removal+high-pressure        filtration dehydration", 100% reduction of water-based drilling cuttings on the sea can be achieved through primary        drilling cuttings drying, secondary solid phase removal, and tertiary liquid phase purification.

Features:

High processing efficiency per unit area, saving workspace;

100% reduction of water-based drill cuttings during drilling,and 100% reuse of treated liquid phase;

Full process operation parameter monitoring with high degree of automation;

Full equipment modular design, flexible installation.
