Success story

Estimated ship arrival time service

18 December 2014

Intro

Generally, arrival time assessments are based on the distance to port and the mean speed of the ship. Our service takes into account the wind, wave, and current conditions during the trip and the effects that they have on the speed.

Background project

Upon arrival of a ship in the harbor a quay needs to be free for offloading of for example containers or bulk products. For this purpose a time slot has been requested and hinterland transport arranged by for example barges or trains and trucks. A ship failing to arrive in time results in infra-structure not being used or last minute reallocation of resources.

Issue and needs

To optimize marine transport the current ship position has to be monitored and time to harbour estimated. The latter is influenced by MetOcean conditions along the planned shipping route and requires accurate weather forecasts and ship response parameters.

Proposed solution

To predict ship arrival time the effect of wind, waves and currents on its velocity is determined. Assessment of ship response parameters is based on actual shipping data and MetOcean conditions and does not require a dedicated complex physical model of the ship’s hydrodynamic behaviour. The technology combines near real-time ship data, MetOcean forecasts and the ship response parameters to predict sailing times. Ship position and speed are monitored using AIS technology. Historic AIS data and MetOcean data are analysed to assess ship speed related to ambient waves, wind and currents.

Industry perspective

The technology will increase efficiency in the maritime transport sector and ports. The service enables optimized use of harbour infrastructure and increase throughput capacity including use of hinterland connections. The service is provided to support the maritime transport sector, ship owners and seaport authorities.

Knowledge of the sea bottom topography is essential for activities such as shipping, fishing, dredging, offshore construction and pipeline laying, amongst other things. Assessment of the sea bottom topography with present state-of-the-art techniques (ship-based-echosounders) may become relatively expensive a combination of the traditional methods with remote sensing (RS) techniques may greatly reduce survey costs. Morphological Charts can be used for detection and monitoring of morphological features such as sand waves and channels, and for change detection. These charts provide unscaled depth variations and do not require calibration data. The main information content is in the location of distinct features, e.g. crests of sand waves or channel walls.

Accurate wave and wind forecasts are crucial to minimise risks and optimise efficiency of maritime operations. To foresee in this need HERMESS provides offshore and nearshore forecasts worldwide. To get the most consistent results the wind field data that drive the model are corrected and updated with satellite measurements. Furthermore we are offering the opportunity to fine-tune the local forecast by making use of local measurements.
