Safe Bunkering for LNG – A Challenge to Global Growth

December 26, 2013

LNG bunkering in Europe
A limiting factor to the increase in the use of LNG fueled ships on a larger scale is the lack of LNG bunkering infrastructure worldwide, with exceptions being northern European countries which have been at the forefront on maritime LNG fuel development, such as Norway and Sweden. DNV GL recently launched a Recommended Practice for authorities, LNG bunker suppliers and ship operators, which provides guidance on how LNG bunkering can be done in safely and efficiently. According to DNV GL, LNG-fuelled ships have logged over 130 ship-years of operation in Norwegian waters. In some parts of the world, operators, suppliers and regulators have gained experience in all aspects of LNG-fuelled ship operations in recent years.

The Future of Maritime LNG Propulsion

December 23, 2013

The use of liquid natural gas (LNG) as a marine fuel is increasing as new environmental regulations are enacted and bunkering facilities are expanded. Some forecast predict that around 10,000 vessels could be adopting LNG propulsion by 2020 compared to less than 100 today and classification society Det Norske Veritas had predicted that LNG would become the dominant fuel source for all merchant ships within 40 years. The main reason for this expected growth is because of strict emission regulations requiring the reduction of sulfur oxides (SOx) and nitrogen oxides (NOx) to 0.1 percent in Emission Control Areas (ECAs) by 2015 and 0.5 percent globally by 2020.

Triple-E Class Impact on the Container Ship Industry

November 2, 2013

The new Triple-E class container ships are set to debut with Maersk livery. Maersk’s purpose in acquiring these behemoths is to take advantage of thier enormous capacity, which will enable Maersk to carry the greatest number of containers in the most energy efficient way, with the smallest CO2 footprint. Maersk thinks the time is ripe to order these new vessels as the annual market growth for Asia to Europe (westbound) trade is forecast to be in the 5-8% range during 2011-2015. The Triple-E’s design expanded the ship’s inside cavity, attaining a 16% capacity increase in comparison to the Maersk Emma (equivalent to 2,500 containers), despite relatively little change in length and width. The Triple-E is designed to transport more cargo without adding engine power.

Building Big – Maersk’s Triple-E class Container Carriers

a d b e e d c d wi
Maersk Line is building the world’s largest container ships to be known as the Triple-E class. Each ship will have a capacity of 18,000 20-foot containers (TEU) or most probably 9,000 40-foot containers, the later being more in use than the former. It’s important to note that TEU stands for twenty-foot equivalent units, therefore when dealing with 40-foot containers, we describe these as FEU (forty-foot equivalent). FEU may also be used to categorize two 20 foot containers. With the launching of this new class of container carrying ships Maersk will break its own world record. The Triple-E class ships are 400 meters long, 59 meters wide and 73 meters high, and the 20 new vessels on order are expected to be deployed on the vital Asia to Europe trade routes.

Preventing Ballast Water Invasive Species Propagation

Ballast water is used to stabilize ships at sea, being pumped-in to weigh down a ship for safe navigational conditions when the ships hull is not filled with cargo for a voyage. Controlling the amount of ballast water embarked helps to reduce stress on the hull while providing transverse stability when underway. The correct use of ballast also makes ship propulsion more efficient and increases maneuverability. By correctly controlling the amount and location of ballast within the hull an officer can compensate for weight lost due to fuel and water consumption during a voyage, always maintaining optimum stability. Just by reading the paragraph above it becomes clear to any landlubber that ballast water is vital for safe ship operations.

New Pre-salt Port Worries Environmentalists

The Ponta Negra Terminal (TPN) to be built at the south side of Jaconé Beach at Ponta Negra Point is to be one of the biggest ports in the country. DTA Engineering, responsible for the project, unofficially called the Pre-salt port and with an investment forecast of $5,4 billion in an area of 557,2 thousand square meters, is expected to link oil & gas pipelines from the Pre-salt plays to the Petrochemical complex of the state of Rio de Janeiro (Comperj), which is located in the nearby city of Itaborai. The project includes a port, a ship and rig maintenance shipyard and a refinery. Authorities consider the location ideal due to the fact that the point has a natural depth of 30 meters.

Virtual Shipyards in Brazil – Still a long way to go to supply the demand for ships from the O&G Industry

June 16, 2013

Most of the new shipyards to be built in Brazil are still on the drawing board. The exceptions are the Inhaúma yard, which was taken over by Petrobras and is being renovated as a ship repair yard, and the OSX shipyard which will be located within the Açu port complex in the northern part of the state of Rio de Janeiro. As both the port and the shipyard are owned by the EBX group, which also owns OGX OIL & GAS, they have guaranteed orders and have already received a partial environmental license and construction has already begun. The orders are guaranteed by the demand for ships from OGX, so they do not depend directly on orders from Petrobras.

The New World Order, Like it or Not

September 27, 2010

According to Petrobras and many other players involved in the O&G market, Rio de Janeiro is the new oil capital of the world.Now that actually may come to be, but there is still a ways to go. As it is, we are all happy campers down here. It is not hard to tell that the simple possibility of this happening is blowing minds and aggravating some players, especially in Houston. The fact is that what goes up must eventually come down and that´s just the way it is. I must admit that for a Brazilian like me, a middle class wanna be, the numbers are quite thrilling. However, there is no running from the fact that the challenges are many. You can have all the oil in the world…
