Cargo containment system Liquefied Natural Gas (CCS LNG) of Mark-III is an insulation material is installed on inner hull and its surface is covered with a metallic membrane sheet. The Mark-III system adopts corrugated stainless steel as the membrane. The stainless steel is corrugated both longitudinally and transversely. Previously, the research of Mark-III was based on experimental results. This lead to high research cost. Therefore, an economical and time saving approach namely Finite Element Analysis (FEA) is used. In this study, a static analysis of the stress distribution is conducted with respect to different symmetric and axis-symmetric pressures. As a result, the deformation pattern of the corrugations are shown and compared with the previous experiment.

This innovation adopted virtual approach finite element method as a tool for designing and testing primary structure subject to magnitude pressure. This simulation investigates the profiles changes of small and large corrugations and measures stress at corrugations area.

Remotely Operated Underwater Vehicles (ROVs) is dominant to underwater robotics which has very high demand in marine exploration and discovery. This study discussed the up thrust force or buoyancy effects for the fabricated ROV which named as MIMET-ROVTek ROVorknown as MIROV. The study is conducted on the stability in terms of centre of mass, centre of gravity, buoyancy and centroid of the MIROV body. In addition, this study also describe the capability of ROV body works at the actual sites in Pulau Tuba, Langkawi up to depth of 15 meters and 2 knots current with a good buoyancy. The material used for ROV ballastis Polyvinyl Chloride (PVC). The centre of gravity, centre of mass, centroid and buoyancy is defined using theoretical mathematical calculation by taking all related physical parameters. Moreover, this MIROV body is modelled from scratch. The final model design were used the commercial computer aided software; SolidWork®. The proven calculated buoyancy were measured to shows...

A buoy is a structure that is float on the sea surface used for the navigational, marine science, monitoring the meteorology and oceanography changes of the marine environment. This article presents a literature review on research and development of floating buoy technology for research purposes. The article starts with the historical background of various buoy technologies. Then, floating buoy working principles used for research are discussed. The reviewed according to the type of buoy technology for research purposes (tsunami buoy type, wave buoy type, weather buoy type, and profiling buoy type). This is followed by an overview of the buoy applications that have been undertaken by Malaysian research communities. The proposed concept design of buoy will be shown with the initial stability parameters analysis. To conclude, based on the research work undertaken thus far, what the researchers should expect as future work are suggested.
