To solve the problem that small rescue vessels are seriously affected by waves when working at sea, which causes damage to crew and equipment, a catamaran with suspended articulated cabin is designed. The multi-body dynamic model of whole vessel based on SimMechanics built, prototype tested water. correctness verified three aspects roll motion, pitch heave motion platform. platform simulated un...

An experimental technique to accurately quantify the deformation and the bend-twist coupling of high performance composite foils under fluid loading is presented. The experimental results are reproduced in a Computational Fluid Dynamic (CFD) environment to assess the impact of board deflection and changes in pitch angle on vertical force generated in the C-foils while sailing under increased hy...

Currently, marine transportation in the world still uses fossil fuels. In addition to running low on supplies, fuels also cause emissions that global warming. Sea generates around 1,000 million tonnes of CO2 emissions. Therefore, exploration alternative energy is becoming a popular research direction. Several renewable sources include solar and wind energy. Indonesia has an average speed above ...

The energy ship is a new concept for offshore wind capture. It consists of wind-propelled that generates electricity using water turbines attached underneath its hull. Since it not grid-connected, the generated stored aboard (for instance, batteries or through conversion to hydrogen an electrolyzer). This has received little attention until today. Particularly, there had been yet experimental p...

Battery-powered ships constitute a solution to the pathway zero-emission shipping. This article studies comparatively and assesses performance of battery-powered vessels implementing Life Cycle Analysis (LCA) Cost Assessment (LCCA). A case study fast catamaran ferry is employed assessed against respective conventional revealing advantages drawbacks these two alternative solutions. LCA LCCA take...

Sailboats have varying values with changes in market conditions and aging. This paper analyzed the characteristics economic of monohull along catamaran their respective regions. The also carried out Spearman correlation analysis on listing prices. gradient boosting decision tree model was established to calculate feature importance each variable price, accuracy reached over 86%. It indicated th...
