Calibration is the process of accurately determining the capacity or partial capacities of a tank and expressing this capacity as a volume for a given linear increment or height of liquid. In other words, tank calibration also means measuring storage tanks, horizontal bullets, spherical tanks, vats, casks, barges, ship tanks and liquid bulk containers. These measurements provide the necessary dimensions for calculation of calibration charts.

Objects falling from height remain one of the most common causes of offshore accidents, despite the considerable effort the oil and gas industry has made to reduce the risks. Dropped Object Prevention Scheme (DROPS) surveys and inspections are a vital element of any dropped object control and prevention management system. PGLS can help to prevent a potential dropped object, becoming another unwelcome safety statistic by conducting a detailed dropped object survey of hazardous areas. We undertake a comprehensive sweep of each area to compile a detailed hazards inventory list, supplemented by photographs. PGSL uses its in-house developed packages and apps for conducting dropped object inspections. We implement programs in accordance with regulatory and customer requirements, DROPS society guidelines and PGSL’s Falling Objects and Securing of Equipment procedure. The latter contains the following requirements for establishing and maintaining measures that prevent incidents: Securing loose equipment

• An inspection program for safety devices for loose equipment
• An inspection program for equipment aloft
• Follow-up procedures after equipment aloft has been subjected to abnormal loads
• Operational safety measures for areas exposed to falling objects
• Physical barriers against falling objects.

Areas that we typically cover on a full survey can include the following or be specific to your individual requirements :

• Derricks & Masts
• Travel/PH Equipment
• Comms Mast
• Substructure
• Jack House & Legs
• Rig Equipment

Our inspections are tailored to your DROPS programs such as:

• Documenting equipment location by inspection area
• Photographing each item surveyed
• Describing each item surveyed
• Inspecting and documenting primary securing methods
• Inspecting and documenting secondary securing methods
• DROPS remedial works

PGSL can provide an extensive range of their services with the aid of Rope Access services to minimize costs associated with both time consuming and expensive scaffold systems. It has been shown throughout the last number of years that this activity is an extremely safe method for execution of numerous applications at elevated locations and those that have restricted access. PGSL utilize Rope Access trained NDT technicians for Structural Inspection and Survey work. Rope Access is a safe, efficient and time saving method derived from recreational climbing and caving but modified to utilize a twin rope system for enhanced safety in industrial use. This makes it the access method of choice for our industry, thus eliminating the need for costly and time consuming scaffolding. With our own team of IRATA qualified rope access personnel, PGSL has the capability to expand any of its broad range of services to areas that remain difficult to access by standard methods.

WELDER TRAINING, WELDER TEST AND CERTIFICATION

SWelding codes and standards address all aspects of design and fabrication of welded components, including welding procedure specifications, quality control and quality assurance during welding and necessary welding skills for a given welding procedure in all industry sectors. The relevant code is often specified by the end user or client as a contractual agreement in order to control the characteristics of the welded components that may affect the service requirements. Compliance to these welding codes is therefore a must. Our welding inspectors are aware of what codes or standards are applicable in a certain area and understand the requirements of the relevant document. We can perform various qualification and testing services in order to verify that the welder or welding operator is capable of making welds within the scope of that standard or that the instructions in the welding procedure specifications are accurate. Welding Procedure Qualification Test We provide welding procedures for welding compliance with the American Welding Society (AWS), American Society of Mechanical Engineers (ASME), American Petroleum Institute (API), diverse pressure vessel regulations in Europe, such as PED, TPED, SPVD or the German pressure vessel code AD 2000-Merkblatt, ISO 3834, EN 1090, EN 15085, or DIN 2303. PGSL can examine contract documentation & establish customer welding demands and requirements. We can design efficient weld procedures that will provide maximum approval range. We will examine and advise on the welding techniques being employed. Welder Certification Welder certification is based on specially designed tests to determine a welder’s skill and ability to deposit sound weld metal. The welder’s tests consist of many variables, including the specific welding process, type of metal, thickness, joint design, position, and others. Most often, the test is conducted in accordance with a particular code. Once welder test requirements have been established, we can carry out an assessment to evaluate the welders’ current skill level. Welders are certified in accordance with the standards such as BS EN9606-1 2013 Qualification test for welders, ASME IX. AWS CWB and DIN. Welder certification test range in all conventional weld processes vary from Fillet welds welded in a flat position to pipes welded in a fixed 45° (HLO 45/ 6G) position. Brazing Operator Qualification Test and Brazing Certification We carry out the qualification of Brazing Procedures allowing companies to achieve their goals in meeting industry standards. Our experts visit the customer facility for review, understand and recommend the required Brazing procedures to be qualified and support from preparation of test coupons to actual testing and certification. We also qualify Brazing Operators and train them in using the qualified BPS. We also help maintain the database of qualifications to facilitate timely renewals by periodic monitoring as per relevant code. We provide brazing procedures for brazing compliance with ASME Sec IX (Boiler and pressure vessel code) BS EN 13134:2000 (Brazing Procedure Approval)
