Sea Trial for optimization: a journey of engineering, calibrating and testing on a LNG Carrier

Memorable Experience for one of our engineers:

“As an engineer specializing in diesel engines, this was an amazing experience for him. The power of the steam turbine showcases the versatility of maritime engineering and offers a glimpse into the rich history of shipping,” he shared. The engineer captured footage from the remarkable sea trial and the steam turbine for those eager to catch a glimpse of this unique experience watch here:

This experience highlights the innovative aspects of maritime engineering and showcases the diversity of possibilities that engineers continue to discover and develop in modern shipping. His mission? To repair and calibrate various PI and PID controllers and their positioners, which are essential for ensuring stability and precision in the vessel’s systems.

Critical Calibration of Maritime Controls

PI and PID controllers play a crucial role in maritime operations, especially on complex vessels like LNG carriers. These controllers regulate everything from temperature and pressure to speed and fuel injection, supporting both energy efficiency and operational safety. To ensure that everything is working properly sea trial for final adjustments and commissioning are one of crucial things after replacement. The first phase of this assignment involved the precise calibration of these systems, setting the stage for a smooth sea trial.

Sea Trial for Optimization

During the second phase, the sea trial, the systems underwent extensive testing under real-life conditions, allowing the engineer to make final adjustments to optimize the vessel's performance. “This is always a special moment, where weeks of hard work come together in the ultimate test of the ship in its natural environment,” the engineer noted.

Highlight: Sailing on a Steam Turbine

The highlight of the experience was traveling on the vessel’s steam turbine propulsion system, powered by two boilers operating at an impressive 60 bar. For the engineer, who specializes in diesel engines, this was a rare and breathtaking experience. Steam turbines are less common today than diesel engines, yet they remain valued in the LNG sector for their power and reliability. The advantage of this LNG vessel is that it can use the LNG she carries as fuel for the boiler.
