Prior to the commencement of a period of employment involving multiple voyages, the vessel owners as well as the charterers will draw up a time charter agreement detailing various aspects of the vessel and voyages. A large part of this agreement has to do with vessel performance, including the vessel description, speed and consumption warranties, …
Masters often receive competing weather routing advice due to shipowners, charterers and ship operators using their own weather service provider. While savings in time, cost, fuel, and emissions are key to optimal routing safety always takes precedence. This case example highlights some of the dilemmas that can arise. Background In early December a 33,000 DWT …
With the northern hemisphere now well into winter it is also the time of year when Tehuantepecer wind events occur more frequently. So what is a Tehuantepecer event you may ask? A Tehuantepecer (also called Tehuano Wind) is a post frontal N-NE’ly mountain gap wind that originates in the Bay of Campeche as cold high …
1st December marks the start of the northern hemisphere meteorological winter, when routing vessels across the North Pacific and North Atlantic Ocean basins becomes a little more challenging as more benign and predictable summer weather conditions are replaced by a stormy and often more volatile pattern. So right on cue one of the most common …
Monitoring potential changes in upper air patterns is extremely important as this provides longer lead times for ship route planning purposes. The Polar Vortex (PV) is no exception, and while many associate this with cold air and freezing conditions, a PV event plays a significant role in altering weather patterns at sea. It is an …
StratumFive was pleased to be among the companies who signed an open letter to the maritime industry for COP 26. The letter calls for action to realise a huge opportunity to save time and money by investing in and applying energy efficiency and renewable propulsion technologies. All measures taken now to reduce emissions through clean …
Shipping’s Cleantech Revolution needs more than just new fuels
The Northern Sea Route (NSR) is a shipping lane between the Atlantic Ocean and the Pacific Ocean along the Russian coast of Siberia and the Far East, crossing five Arctic Seas: the Barents Sea, the Kara Sea, the Laptev Sea, the East Siberian Sea and the Chukchi Sea. This route offers significant savings between the …
La Niña conditions developed earlier this autumn, and are expected to persist through the winter according to the Climate Prediction Center. These conditions, which are characterized by below-average sea surface temperatures (SSTs) in the central and eastern equatorial Pacific, will lead to a wide range of impacts to global weather patterns for as long as …
Among the many weather events anticipated as the northern hemisphere starts to move in to Winter, the developing Northeast (NE) Monsoon regime is one event that we keep a close eye on. For this blog, we will dive into how this monsoon regime forms and talk about how the incoming surge of north-easterly (NE’ly) winds, …
Meteorologists have traditionally analysed weather maps of upper air conditions using constant pressure surfaces as knowledge of what is happening aloft is needed to get an accurate picture overall since weather at the surface is influenced by conditions high up in the atmosphere. These weather maps or charts are prepared for several mandatory pressure levels …
