UNDERWATER WELDING

Dry Hyperbaric welding is the process of welding at elevated pressures underwater. It is performed inside a specially constructed cofferdam, creating a dry environment. Defective shell plating sections can be replaced underwater by class approved permanent dry welding. When necessary, custom fabrication of habitats is carried out on-site. Welding is performed in a wet environment using shielded metal arc welding with a waterproof electrode. This is commonly used for temporary repairs and construction. Marine Tankers performs both wet welding for temporary or permanent underwater repairs, from anode renewal to rudder or hull plating repairs. Other applications include sacrificial anode replacement, damage control for marine casualties, rope guard repairs, rudder repairs, hull weld repairs, bilge keel repairs, external doubler plates and sealing up disused inlets and outlets.

Safe, reliable and cost effective

Underwater welding is a safe, reliable and cost effective technique for temporary repair and construction. We diligently test new materials and methods in our simulated underwater environment in order to be at the forefront of the latest technology.

Under 24hrs & no drydocking

The total time for welding underwater is normally under 24 hrs, with no drydocking or down time. It’s a cost effective solution that is guaranteed to get you back on schedule fast. Feel free to contact us!

Maintenance

When you want full control of the equipment's lifecycle. Through condition-based maintenance and expertise in the generation, distribution and propulsion systems, we balance the cost of maintenance with the risk of failure. Whether it is at dry-docking or loading/unloading cargo, we offer maintenance services that best fit the vessel's schedule.Our safety Group engineering and design resource covers a wide range of disciplines and work scopes including mechanical, structural, marine, oil and gas engineering, all supported by the latest technology. Additionally for projects such as general fabrication we can either design your requirements in-house or provide additional support to your engineering teams on an ad hoc basis. With our in-house engineering capability you have the option of either providing us with the drawings of the components that you require to be fabricated or we can design and build to your requirements. Our safety Group has a proven track record for responding quickly to the customer requirements for urgent orders, ensuring that client projects are not delayed. Our priority is to ensure we work fast to efficiently meet the clients’ immediate project needs.

Electrical installation & inspection testing

Our manufactures and markets a broad offering of portable and laboratory measuring instruments covering the electrical and electronics sectors as well as physical quantities. As the inventor of multiple patents,We proposes an innovative offering of Test and Measurement instruments enabling professionals to test the reliability, safety and effectiveness of devices, equipment and processes. The solutions for measuring electrical and physical quantities under Our brands cover the whole range of professionals’ present requirements.

Engineer, fabricate & install industrial insulation blankets:Boiler and engine rooms are usually thought of as hot, uncomfortable places to work. Add the space constraints of marine installations and conditions can range from inhospitable to downright dangerous, as piping systems can exceed temperatures of 1,000 ºF (537 ºC). So when a fleet of drilling ships reported that their exhaust insulation had come apart and needed to be replaced, it was all hands a manufacturer of insulation solutions.

Electrical installation (cable pulling & termination – installation & modifications of cable trays): The main function of cable trays and cable ladders is to support electric cables securely between two points. These are structural mechanical components in the electrical installation. They are compliant with standard, defining mainly:
• Load bearing
• Electrical continuity
• Earthing
• Electromagnetic compatibility.

Condition monitoring solutions for motors and generators

We provide motors, generators and mechanical power transmission products, services and expertise to save energy and improve customers’ processes over the total life cycle of our products, and beyond.We provide motors, generators and mechanical power transmission products, services and expertise to save energy and improve customers’ processes over the total life cycle of our products, and beyond.Our solutions cover all major components of motors and generators: rotor, stator, shaft, bearings, cooler, brushes or slip rings, as well as overall mechanical condition and, for motors, power supply quality. We can therefore help you to address all the potential problem areas in your motors and generators. Furthermore, our versatile services are not limited to our products – they are just as effective on equipment from any manufacturer.

Condition monitoring

Bring predictability to maintenance: By measuring mechanical and electrical condition of the power plant, automation and propulsion system, we observe trends and plan a long term upgrade/retrofit program. This enables our customers to predict their long-term maintenance budget for an individual vessel or an entire fleet.

Increase flexibility through condition-based maintenance: Through condition monitoring, ship managers have more flexibility to schedule maintenance work based on the actual condition of the equipment.Our condition monitoring reports are valid as OEM recommendation in an alternative survey arrangement towards classification societies.

Plan ahead for effective response: Through condition monitoring, ship managers have more flexibility to schedule maintenance work based on the actual condition of the equipment.Our condition monitoring reports are valid as OEM recommendation in an alternative survey arrangement towards classification societies.With service engineers specialized in our systems, we help superintendents to prepare for specific service actions, so the equipment can be overhauled and maintained properly. Our maintenance plans can be customized based on the customer's operations.

Preventive maintenance

Nobody can deliver a better maintenance service than the engineers who created and developed the systems themselves.
