Recent targets have increased pressure for the maritime sector to accelerate uptake of clean fuels. A potential future fuel shipping is hydrogen, however there a common perception that volume requirements this are too large deep sea shipping. This study has developed range techniques accurately simulate hydrogen case vessel. Hydrogen can use cells, which achieve higher efficiencies than combustion methods, but may require battery hybrid system meet changes in demand. series novel models...
An experimental investigation into the performance of high speed hard chine planing hulls in irregular waves has been conducted. A new series models representative current design practice was developed and tested experimentally. Measurements rigid body motions accelerations were made at three speeds order to assess influence fundamental parameters on seakeeping human factors crew, with an aim provide designers useful data. Response data, such as heave pitch accelerations, are presented...
The fishing industry is heavily reliant on the use of fossil fuel and emits large quantities greenhouse gases other atmospheric pollutants. Methods used to calculate vessel emissions inventories have traditionally utilised estimates efficiency per unit catch. These methods weaknesses because they do not easily allow temporal geographical allocation emissions. A proportion small commercial vessels are also omitted from global shipping such as International Maritime Organisation's Greenhouse...
A fixed 25deg deadrise angle wedge is allowed to fall from a range of heights into static water. high-speed (up 5000 frames s?1) camera used visualize the impact and subsequent formation jet flows droplets. Unsteady pressure measurements at six locations across surface are measured 10 kHz. Two accelerometers (10g, 100g) mounted above apex measure vertical acceleration. purpose-built position gauge analysis synchronized video allows motion be captured. The synchronization these data with...
Very Large Floating Structure (VLFS) is a unique concept of ocean structures primary because their unprecedented length, displacement cost and associated hydroelastic response. International Ship Offshore Structures Congress (ISSC) had paid attention to the emerging novel technology launched Special Task Committee investigate state art in technology. This paper summarizes activities committee. A brief overview VLFS given first for readers new subject. History, application uniqueness with...
Various deterministic models for economic ship speed optimisation exist in the literature, but none considered time charter contract, and particular influence of redelivery time. This paper studies optimal a on (time) contract through development an Operational Research (OR) model. The charterer's objective is to maximise Net Present Value (NPV) cash-flow function ship's activities over relevant future horizon H, where H can be interpreted as any possible day within window specified clause....
The reduction of harmful emissions from the international shipping sector is necessary. On-board energy demand can be categorised as either: propulsion, or auxiliary services. Auxiliary services contribute a significant proportion demand, with major loads including: compressors, pumps, and HVAC (heating, ventilation, air-conditioning). Typically, this met using same fuel source main propulsion (i.e. fossil fuels). This study has analysed whether large scale ships could feasibly reduced by...
Installing an energy saving device such as a pre-swirl duct (PSD) is major investment for ship owner and prior to order reliable prediction of the savings required. Currently there no standard how be carried out, possible alternatives are both model-scale tests in towing tanks with associated scaling procedures, well methods based on computational fluid dynamics (CFD). This paper summarizes CFD benchmark study comparing industrial state-of-the-art ship-scale predictions power reduction...
To estimate the powering and manoeuvring performance of ship in a real seaway, it is essential to accurately determine forces acting on hull, propeller, rudder their interaction effects when operating at an angle drift. The rotating propeller alters fluid flow around upstream hull downstream rudder. Likewise, non-zero drift or applied, significant crossflow generated across plane, changing wakefield actual propeller. A study conducted analyse hull–propeller–rudder benchmark KRISO Container...
Kite propulsion has emerged as an attractive means to harness wind power in a way that yields environmental and finanical benefits. This paper compares results from two line tension models with experimentall recorded time histories for dynamic kite flight. New methodologies investigating performance are established. The first zero mass model assumes the lines weightless. second lumped considers kite's thus makes use of equations motion. It is found different converge same result limit where...
In order to understand the physical origin of passive resistance in swimming breakdown for a swimmer is investigated. A combination empirical methods and theoretical analysis used predict speed range 0 – 2 ms-1 shown provide similar results those from experimental testing. Typical magnitudes wave, viscous pressure skin friction contribute 59%, 33% 8% total respectively at free swim speed. comparison made between widely Velocity Perturbation Method Naval Architecture based approach predicting...
