Inspection
Inspection

Under Water Inspection (s) in lieu of Dry-Docking (UWILD), or In Water Surveys (IWS), are required to ensure the structural and operational integrity of a marine asset throughout its operational life span.

UW-Welding-Cutting
U/W Welding / Cutting

PVD Training provides well trained and certified divers to accomplish the overhead  underwater welding, whenever it is requested or judged necessary, by providing guaranteed results.

Maintenance-&-Repair
Maintenance & Repair

With an extensive background in under water, we recognize and understand how harsh and destructive the underwater environment can be on metal, concrete, and other building materials. Our professional divers are trained to perform underwater maintenance, and repair services on bridges, piers, water tanks, submersed pipelines, coastal structures, and much more.

Underwater-corrosion repair
Underwater corrosion repair

Underwater corrosion repair are specifically engineered to maximize adhesion in the most challenging conditions, adhering strongly even when applied underwater, in splash zones or on to damp, sweating or oily steel and concrete.

Underwater-Pipeline-Repair-replacement-&-installation
Underwater Pipeline Repair-replacement & installation

PVD Training dive technicians analyze inspection results to determine the extent of necessary repairs-replacement and prepare recommendations for our clients. We delivers unique underwater repair solutions of fixed and floating platforms, sub-sea pipelines and offshore structures.

Repair-of-Concrete
Repair of Concrete

Underwater concrete structures are prone to damage due to many reasons. There are some methods which are specially adapted to repair these damages. Care should be taken to ensure that the damaged area is not contaminated before the application of the repair material.

In-Water-Survey
In-Water Survey

In-water survey is a method of surveying the underwater parts of a ship while it is still afloat instead of having to dry-dock it for examination of these areas as was  conventionally done.

Hydrographic Surveys

Hydrographic surveying is the science of detecting, measuring and mapping water bodies to ascertain depth and locate submerged features. A hydrographic survey can determine a minimum depth, under keel clearance, 3D bottom model, capacities and a host of other information.  To ensure there are no dangers to navigation, it is important that mariners know precise water depths.  To determine the arrangement of the sea floor assists with anchoring, dredging, structure construction and fisheries habitat.

We have provided hydrographic surveys to support dredging projects, waterfront development, dock installations, water dependent engineering, environmental remediation and more.

We provide the following services:

  • Current metering for power station outfalls
  • Warm-water plume monitoring from industrial plants
  • Flow metering of small rivers for flood prevention studies
  • Magnetometer surveys to detect buried underwater sewage outfall pipes
  • Water column temperature monitoring

 

Geophysical Survey

Geophysical Survey

The science of surveying in the nearshore environment goes beyond the mere utilization of offshore survey equipment in shallow waters. Surveying in the nearshore environment requires a specialized set of skills to understand the potentially hazardous conditions of the coastal environment (such as tidal currents and surf zones).

Advanced technological developments linked with more funding have meant that offshore projects are encompassing more of the ocean’s “Blue Water” environments. Whether this is increased ploughing depth to in excess of 1,000m for submarine cable installations, or deep oil/gas drilling programs, PVD Training is well placed to provide surveying solutions for this environment.

PVD Training’s services include both a desktop study ability utilizing our vast database resources, as well as field surveying and consultancy.

In the ever demanding Oil & Gas, Submarine Telecoms and Marine Infrastructure Industries, PVD Training offer bespoke near real-time report delivery by integrating data gathering and processing with onboard charting and reporting to meet the time constraints set by the client. Deliverables are provided in a professional format as per client request, including CAD and GIS formats.

Seabed-mapping

 

Seabed mapping surveys would be undertaken for general mapping of a defined area of interest and or as part of a route survey for the planning of pipeline installations.

Seabed mapping survey enables the topography of the seafloor to be examined for wrecks, manmade artifacts, debris, current infrastructure, and other points of interest. This ensures that pipes and cables are not laid in potentially hazardous areas. The composition of the seabed can also be determined for burial and trenching evaluation. Side Scan Sonars or Multibeam Echosounders are predominantly used to obtain the data required to produce high quality Digital Terrain Models (DTM’s).
