Greetings, this is PK Marine.

The small & mid-sized shipbuilding industry is leading major changes: high speeds, lightweight materials (Al/FRP), and complex propulsion (Gas Turbine/Electric). For such advanced vessels, the complexity of ‘Sea Trials’—vital for final quality—and the need for efficient MRO capabilities are higher than ever.

PK Marine is a specialist in Small & Mid-sized Vessel Sea Trials & Engineering, built to meet these demands. Our team comprises elite veterans who have directly commanded and verified diverse small & mid-sized craft (high-speed to special-purpose boats) for over 30 years. Beyond verification, we offer operation training and systematic MRO guidance based on our deep know-how.

With expertise spanning Sea Trials to MRO, we promise to be the best partner for your project’s success.

PK Marine’s team consists of verified experts who have directly commanded numerous small & mid-sized vessels and managed newbuilding acceptance across diverse environments.

Extensive Operation & Command Experience

Extensive command experience with small & mid-sized vessels (high-speed, patrol, & special-purpose craft).

Deep Vessel Understanding: Expertise in distinct vessel traits, ranging from lightweight hull characteristics (Aluminum/FRP) to high-speed maneuvering.
Propulsion Expertise: Capable of verifying complex power systems, from high-speed Diesel and Waterjets to the latest Hybrid/Electric systems and Gas Turbines.

Newbuilding Acceptance & Verification Experts

Beyond simple operation, successfully executed numerous newbuilding acceptance projects.

Systematic Protocols: We manage the entire verification process systematically, from construction completion to final delivery.
Defect ID & Optimization: We perform Limit Tests to identify early defects during construction and optimize system performance.

Systematic Safety & Crisis Management

Applying decades of systematic protocols and crisis management know-how to Sea Trials.

Rigorous Safety: Prioritizing the safety of vessels and personnel against unpredictable sea conditions through strict safety systems.
Expert Troubleshooting: Skilled engineers provide immediate, professional solutions for technical issues (engines, thrusters, generators) during trials.
