Underwater services will not be success without support from all the divers that involved in a project. Our commitment is always providing divers with well experienced, qualified, and good manners to client. We have two main categories of diving work which is Air Diving and Mixed Gas Diving.

Diving Services

This company can do the inspection and certification of structure at near short(ex. jetty) and also in offshore, supported by experienced and professional personnel and partner in Engineering service and PJIT (third party surveyor) with Directorate General of MIGAS standard.

Technology of Underwater Dry Welding is not new matter in the diving world. Welding by using this technology can yield the excellent quality of welding. Supported by expert and professional partner, this technology have been developed and applicable more easy and simple from the previously method.

In the services related to the Installation work, Maintenance work and Repair work of offshore facility and also near shore, PADI besides having the service but also can provide required materials (for example; Sacrificial Anode, Impress Current, Retropod Anode, Tape of Coat and Under Water Paint).

One of problems of submarine pipeline is the presence of cavity (free span) between pipe and seabed, which is on certain boundary of the pipeline have to be supported ( to be given supporting) and the solution is with installation of grout-bag by diver and or by using R.O.V. PADI also provides the material of grout-bagging.

In underwater companies, vessels are used for supporting the underwater project especially in shipping process of equipment and tools to project site. We always support our client by providing vessels that qualified to the standards and requirements. Two vessels that our company have are Patra Marine 3801 and Patra Offshore.

DSV. Patra Marine 3801

Patra Marine has been rebuilt into a diving support vessel. This vessel is fuel efficient and has good capacities for transporting supplies, such as fuel, water, and enough deck cargo space for offshore production and underwater maintenance facilities

MV. Patra Offshore

The Function of Patra Offshore is not only for shipping process. This Vessel have BKI certification and ability to supporting offshore or survey project based on client’s request. Patra Offshore focus on doing geotechnical functions with Geotech Drilling Rig HG 30 as its specification.

Offshore Survey Services

As a maritime country, Indonesia has area covered with sea bigger than with land. This condition makes our company tries to improving the business scope in underwater services which is survey. The purpose of survey is to know the actual condition of underwater contour. Underwater survey purposes are to knowing the contour, texture, and morphology of subsea ground. Those data will be used for deciding the best options on building cable line for telecommunication industry; pipe line, drilling area, and platform construction for oil and gas industry. So underwater survey is very important, right?

There are many Offshore Survey Services that we handle: » Underwater Inspection & Survey of Offshore Structure, Cable & Pipeline (Bathymetry, Deformation Measurement, free Span and High Span etc.) » Underwater Video Recording and Photography Survey. » Navigation / Geodetic » Site Survey » Geophysical - Side Scan Sonar - Echo-sounder - Magnetometer - Sub Bottom Profiling - Seismic » Oceanography - Tide Gauge - Wave Recorder - Current Meter

We are currently in the partnership with GEODEVICE who supply wide range of geophysicial equipment and sofware.

Offshore Support

Patra Dinamika have been involved in supporting offshore project especially in oil and gas industries for many years. We have many clients from Indonesian company like Pertamina Hulu Energi & Kangean Energy and Petronas & Premier Oil as overseas company.

We have been supported oil and gas industry projects for about 25 years. Right now, we are expanding our scope of work to also focus on supporting power plant and energy industry projects. We have involved in Tanjung Jati B (TJB) power plant project for last 2 years.

Maintenance & Repair System

Keeping a machine in good condition, performance, and function it’s a must in our company. We have Planned Maintenance System (PMS) that consist of Preventive, Corrective, and Repair systems depend on the condition of the machine. It is our commitment to give our best services for clients.

This preventive maintenance involves the systematic inspection of equipment where potential problems are detected and corrected in order to prevent equipment failure before it happens. In practice, a preventive maintenance schedule may include things such as cleaning, lubrication, oil changes, adjustments, repairs, inspecting and replacing parts, and partial or complete overhauls that are regularly scheduled.

Our preventive maintenance includes much more than simply performing routine maintenance on equipment. It also involves maintaining accurate records of every inspection and servicing, as well as knowing the lifespan of each part to understand the replacement frequency. These records can help maintenance technicians anticipate the appropriate time to change parts and can also help diagnose problems when they occur. We use preventive maintenance software because it helps collect and organize this information so it is readily available to maintenance technicians.
