Technical Director, Somatrix Marine Limited & Marine Engineering Researcher
Dr. Samuel Dare Olusegun is an engineer and researcher specialising in marine engineering. He currently serves as the Technical Director at Somatrix Marine Limited—a company that delivers innovative solutions for maritime operations. His academic background and professional work centre on applying advanced numerical techniques, such as the Boundary Element Method (BEM) and Finite Element Method (FEM), to study ship dynamics, wave–structure interaction and marine structural integrity. His role blends industry experience with a strong research portfolio.
This study employs a coupled Boundary Element Method (BEM) and Finite Element Method (FEM) to quantify how varying bulkhead numbers and plating thickness influence the stress distribution and displacement within a containership. Configurations with twenty bulkheads—using either 15 mm or 25 mm plating—exhibit superior structural integrity, with critical stress values around 90 Pa. In comparison, a ten‑bulkhead configuration with 20 mm plating shows higher critical stress values (~120 Pa), while a five‑bulkhead/25 mm configuration exhibits the greatest localized displacements. Displacement analyses reveal that designs incorporating twenty bulkheads achieve lower and more uniformly distributed displacements, underscoring the importance of optimising bulkhead design to balance rigidity and flexibility in naval architecture.
Co‑authored by Dr. Olusegun, this paper investigates how adding fins to a standard heat exchanger can significantly improve thermal performance. Comparing a regular device with a fin‑modified version, the study reports that the modified heat exchanger achieves an overall heat transfer rate of approximately 1,200 kW versus about 950 kW for the unmodified exchanger under the same conditions. Log‑mean temperature difference (LMTD) values for the finned unit range from 48.19 °C to 175 °C, whereas the normal exchanger’s LMTD ranges between 18.9 °C and 32 °C. The research concludes that heat‑transfer rates increase with higher inlet temperatures and mass flow rates, demonstrating that construction modifications such as fin addition can markedly enhance exchanger efficiency.
Beyond these works, Dr. Olusegun’s scholarly profile on Google Scholar highlights interests in wave–structure interaction, marine surveying and naval architecture. His body of research often focuses on coupling hydrodynamic loads with structural response using numerical techniques, reflecting a passion for creating safer and more efficient marine vessels.
