Offshore giant cranes are essential in the installation of offshore platforms, and their operation involves several key steps:

1. Transport to Site: The crane is transported to the offshore site, typically aboard a specialized vessel called a crane barge or crane ship.

2. Positioning: Once at the site, the crane vessel is anchored or dynamically positioned to ensure stability. Dynamic positioning systems use thrusters and GPS to maintain the vessel's position.

3. Lifting Components: The crane lifts large components of the offshore platform, such as jacket structures (the platform’s legs), topsides (the upper part where the facilities are housed), and other modules.

4. Lowering and Securing: The crane carefully lowers the components into place. For jackets, they are often driven into the seabed using piles, which are driven by a pile-driving hammer. Topsides are lifted and placed onto the jacket or other supporting structure.

5. Precision Handling: High precision is required, especially in rough seas. The crane’s controls allow for fine adjustments to ensure components align perfectly.

6. Safety Measures: Throughout the process, numerous safety measures are in place, including monitoring weather conditions, checking the integrity of lifting equipment, and ensuring the safety of personnel.

7. Final Checks: After installation, inspections and tests are conducted to ensure that the platform is securely installed and operational.

These cranes are equipped with advanced technologies to handle the enormous weights and to operate under challenging conditions typical of offshore environments.

FROG Transfer - Offshore Platform

Offshore Personnel Basket Transfer

Offshore marine operations often involve crew transfers, especially in areas like oil rigs, gas production sites, and various offshore installations for construction or maintenance. For many years, a range of methods, such as helicopters for air transfers and options like walking, rope swings, crew boats, and cranes for sea transfers, have been employed for both routine and emergency situations.

A significant portion of these transfers utilizes cranes and personnel transfer baskets. These baskets serve a critical role in enhancing safety during marine offshore and ship-to-ship transfers. They are employed to securely lift personnel between two vessels, whether it's ship-to-ship, ship-to-boat, tanker-to-ship, vessel-to-quayside, or between different offshore installations.

The video was recorded from the vessel, highlighting the significant risks that individuals in this profession face in their daily pursuit of livelihood. Life offshore presents a host of challenges, making it a demanding endeavor, yet it is imbued with the blessings of faith.

Champion oil field, also known as Champion Field, is a complex oil and gas field located 40 kilometers northwest of Bandar Seri Begawan. It is situated in water depths ranging from 10 to 45 meters, and the shallow section of the field is covered by coral reefs.

The discovery of the Champion Field dates back to 1970 when the Champion-1 well, drilled in its northernmost part, struck oil. Subsequently, the first oil platform was completed in 1972 to facilitate production from the shallow, oil-bearing intervals. However, in 1974, an unfortunate blow-out incident at Champion-41 temporarily halted the appraisal and development operations. To compensate for this delay, eight separate appraisal wells were drilled between 1975 and 1976.

In 1975, the Champion West field was discovered by well CW-1. It is situated approximately 7 kilometers north-northwest of the Champion Main field and 15 kilometers northeast of Iron Duke. The Champion West field's depth is approximately 40 meters.

Early in 1979, another blow-out occurred in the northern part of the main Champion field, specifically in well CP-141. In 1978, a grid concept for platform placement was introduced for the shallow part of the main field, which contains the majority of the known oil reserves. This design aimed to ensure that most of the future draining operations could be conveniently reached from a platform location.

The construction of centralized field facilities at Champion-7 commenced in 1980 and was completed in 1983.

By 1996, a total of 282 wells had been drilled, out of which 118 were in active production. The Peragam field, located directly beneath the producing Champion field, was discovered through the Peragam-1 exploration well in 1990, thanks to the efforts of Kasmadi Kaling and O'Rourke in 1993. Peragam-1 was initially identified as CW-8, drilled in early 1992 from the Champion West well jacket CWWJ-2 to assess the oil and gas potential of the shallower reservoirs. By 1996, Peragam-1 had a daily gas production rate of 1.5 million cubic meters from PGM-2.

Moving into the 2000s and 2010s, Brunei achieved peak oil production in 2006, reaching 220,000 barrels per day, making it the third-largest producer of oil and gas in Asia. However, due to the depletion of the fields, production declined to 141,000 barrels per day by 2012. This significant shift highlighted the challenges and changes that the Champion oil field and other fields in Brunei were facing in the new millennium.
