TerraWaves Uptime Demo

Transcript

In this video I will demonstrate a simple uptime calculator using TerraWaves. The calculator estimates monthly uptime using historical weather from a 24 year database.

The histogram displays uptime in days, over a 12 month period.

You can interactively determine the uptime associated with any set of weather limits. In this simple demo, the user can set the Significant Wave Height, 10 metre Wind Speed and Peak Period.

Extreme Values - Part I

Arnold Doray

The concept of extreme values can be confusing even to the experienced engineer.

Much of this head scratching involves:
  1. How extreme values should be interpreted in decision making,
  2. How to objectively assess competing estimates of extreme values and
  3. How extreme values relate to well-understood concepts like exceedances.

Terra Weather Launches World’s First Cloud-based Weather Planning Tool for Offshore Industry

Singapore – 26 November 2013 – Offshore planners and asset managers will now be able to plan critical offshore activities with greater confidence and accuracy, by taking advantage of a first ever cloud-based weather planning tool that allows users to get real-time, instant weather information any time, anywhere. All you need is an Internet connection to any web browser from your laptop, tablet or smartphone.

TerraWaves is a global online weather service that uses advanced multi-modeling statistical tools to provide time-critical weather information to businesses operating in the offshore industry, including offshore construction, heavy transport, exploration and production.

Northwest Palawan

Robert Chang

During the Northeast monsoon, winds are generally below 20 knots but may occasionally exceed 30 knots in the first half of the Northeast monsoon (Oct - Dec). Waves are generally below 2.5m but can occasionally exceed 4.5m during this period. The lowest waves occur during the Spring transition (April) when waves are usually below 1.5m.

Offshore Vietnam and Thailand

Robert Chang

The East Coast of Vietnam

Light to moderate (< 15 knots) winds cover the area for much of the year except during the height of the Northeast and Southwest Monsoons. During the Northeast Monsoon, wind speeds increase to mostly fresh-strong (17-27 knots) from November to January. Occasional strong surges in the Northeast Monsoon can cause wind speeds to increase to gale-strong gale (35-45 knots) lasting for up to a few days. The Southwest Monsoon over the area is somewhat weaker than the Northeast Monsoon with mostly fresh (17-21 knots) winds from July to August, increasing to strong-near gale (25-33 knots) at times.

The South China Sea

Robert Chang

The weather in the South China Sea region is characterized by two monsoons: the Northeast and Southwest monsoons, so called because the predominant wind direction is from the northeast and the southwest respectively.

Tropical Cyclones in the South China Sea

Arnold Doray

Tropical Cyclones (also known as Typhoons (in the western Pacific), Hurricanes (Atlantic), or Tropical Revolving Storms) occur all year round over the northern South China Sea. However, the "Typhoon Season" is taken to be from the Autumn transition (Oct) to the first half of the Northeast monsoon (Nov-Dec), when they occur most frequently in the South China Sea.

An Overview of Solitons in the South China Sea

Arnold Doray

Most of the world's oceans are characterised by two layers: The water in the near surface layer has a lower density while the deeper layer has a higher density. Because the top layer is 'lighter', it rides above the denser layer below, much like oil over water. In certain circumstances, waves can develop in the interface between these two layers. Such waves are variously known as solitons, internal solitons, internal waves or non-linear internal waves (NLIW).

Squalls in the South China Sea

Robert Chang

Squalls refer to a sudden increase in wind speeds. The World Meteorological Organisation's definition of a squall is: "A sudden increase of wind speeds by at least 16 knots, the speed rising to 22 knots or more and lasting for at least one minute.". Squalls are associated with thunderstorms and heavy showers and they can last for several minutes but they normally last for less than 10 minutes.

Little Known Facts about the Weather Business

Arnold Doray

In Part I we worked out a cost-based benchmark for forecast services. This helped us see that forecast accuracy is the overriding factor to consider if your offshore operations are high value, or cost a lot to repair or (de)mobilize.

In the second part of this series, we will reveal some hidden facts about the weather business and how these directly impact your weather forecast service's accuracy.

Quantifying Weather-Related Risk in the Development of Offshore Oil & Gas Fields (Part I)

Arnold Doray

Cost management is a key factor to the successful exploitation of offshore assets. The ideal is to minimize project costs while also lowering the associated risk. Unfortunately, in most realistic scenarios it is challenging to do both; instead, the goal is to strike the right balance between risk and cost.
