An Autonomous Underwater Vehicle (AUV) operates independently from the ship and has no connecting cables while ROVs are connected to an operator on the surface host ship by a load-carrying umbilical cable which provides communication and control.
A Remotely Operated underwater Vehicle (ROV) is a tethered underwater mobile device. ROVs are unoccupied, highly maneuverable, and operated by a Continue reading “Micro ROVs enablers for Marine Surveyors”
Load sensors and data gathering have been a familiar part of the sport going back to the late era of IOR – in particular the final generation of IOR supermaxis like Bill Koch’s data-muncher Matador3. Today the technology is prevalent from the America’s Cup to big offshore trimarans to IMOCA, VO65s and including most of the modern superyacht fleet. The demand for data from raceboats is continually increasing – but it’s a form of technology that to date has been relatively inaccessible to the mainstream sailor, not to mention many designers and builders.

The United Nations Conference on Trade and Development (UNCTAD) has published the Review of Maritime Transport 2019 study, presenting in it a fall in maritime trade growth. The report highlights trade policy crosscurrents, geopolitics and sanctions, environmental worries, fuel economics and tensions regarding the Strait of Hormuz, all of which have contributed to slower growth in merchandise trade.
World maritime trade lost its momentum in 2018 due to increased uncertainty, rising tariff tensions between the US and China, as well as concerns regarding other trade policy and political crosscurrents. These relate to a no-deal Brexit, which sent waves through global markets, according to UNCTAD’s Review of Maritime Continue reading “UNCTAD Review of Maritime Transport 2019 reveals a fall in maritime trade growth”
Leading European scientists have released details of a study on the potential of ‘Nanotechnology Marine Applications’ as part of the two-year KETmaritime project.
The International Iberian Nanotechnology Laboratory (INL) is the lead partner in the €1million initiative backed by the European Regional Development Fund.
Project coordinator Ana Vila said, “Humidity and salinity levels at sea cause around 30% of all vessel failures, repair needs and equipment malfunctions. Corrosion and biofouling are two major by-products impacting vessel materials, durability and performance.”
While traditional solutions including protective coatings and paints partially offset Continue reading “Nanotechnology Marine Applications looks at a fix for corrosion and biofouling”
In response to a spike in fake flag registrations, the International Maritime Organization (IMO) is seeking to combat “rogue” national flag registries which are operating without the knowledge of governments they claim to represent, according to the insurer Standard Club.
In recent years, IMO has received reports that 73 vessels were unlawfully flying the flag of the Democratic Republic of the Congo, 91 vessels were illegally registered under the flag of Fiji and 150 vessels were unlawfully registered under the flag of the Federated States of Micronesia. (Micronesian law doesn’t even allow international vessels to flag into its national registry.) The vessels involved are typically smaller, Continue reading “IMO increased efforts to fight fake flag registries”
At a Ministerial Conference held in Torremolinos, Spain, 48 states signed a public declaration to indicate their determination to ratify the 2012 Cape Town Agreement on fishing vessel safety. This is a significant regime to create much-needed safety standards for fishing vessels.
During the Torremolinos Ministerial Conference on Fishing Vessel Safety and Illegal, Unreported and Unregulated (IUU) Fishing (21-23 October), nearly 50 states signed the Torremolinos Declaration. By doing so they have publicly indicated their determination to make sure that the 2012 Cape Town Agreement on fishing vessel safety will enter into force by the tenth anniversary of its adoption, on Continue reading “Fishing vessel safety public declaration signed by nearly 50 States”
Respondents to the BDO survey rated the extent to which enterprise and business risk management is contributing to the success of their organisation at an average 6.4 out of a possible maximum score of 10.0, compared to 5.9 in the 2018 survey. The BDO survey was launched in 2015 with a rating of 6.9.
Owners posted the highest score of all main respondents, followed by managers, but the ratings for charterers and brokers were significantly down on last year. Asia was ahead of Europe in terms of geographical sentiment, but both were behind the Middle East.
The cost and availability of finance was cited by 29% of respondents (up from 17% Continue reading “BDO survey results: BDO show shipping must improve its risk management procedures”
Norway’s Accident Investigation Board (AIBN) has released its report into the tug FFS Achilles grounding and foundering off Farsund on 3 March 2017, suggesting that the presence of a lookout would have reduced the risk of the incident occurring.
The vessel ran aground at a speed of 8.4 knots and sank shortly thereafter due to damage to the bottom under the engine room. FFS Atlas arrived at the scene before the vessel sank and rescued its crew, who were in the life raft. Two out of the three crew members had suffered minor injuries and received medical attention.
The mechanical control system for the propeller units (Voith Schneider) on board Continue reading “AIBN report: Tug grounding and sinking report”
Corrosion is a perennial concern for tank container owners and operators. The stainless steel construction is resistant to staining and corrosion, but may be vulnerable to pitting from certain cargoes or certain cleaning and maintenance operations. Visually minor pitting may conceal development of substantial or even catastrophic corrosion below the surface.
It may be expected that UN Class 8 dangerous cargoes (Corrosive Substances) are the predominant challenge where corrosion of UN portable tanks (tank containers) is concerned, although such commodities are not alone in presenting risk. In terms Continue reading “Corrosion nightmare in tanks, and how to mitigate”
IBM has announced that it is joining an effort to build an autonomous research vessel for an historic transatlantic crossing. In honour of the fourth centennial of the famous voyage of settlers from England to the Americas, it will be named the Mayflower.
The five-ton, wing sail/solar/diesel powered Mayflower Autonomous Ship (MAS) is designed to make 20 knots on its eastbound voyage. Over the course of the 12-day crossing, it will take water samples for research on ocean microplastics, and its sensors will return data on water temperature and nutrient levels. For navigation Continue reading “IBM backs new autonomous research vessel for historic transatlantic voyage”
The European Sea Ports Organisation (ESPO) has released its annual Environmental Report for 2019 indicating that air quality continues to be the top environmental priority of member ports.
The Environmental Report includes over 60 environmental performance benchmarks including figures on green services to shipping (shore-side electricity, LNG and environmentally differentiated port dues) as well as the top 10 environmental priorities of the European ports.
Air quality was followed by energy consumption as priority number two as it is seen Continue reading “Environmental Report for 2019 published by European Sea Ports Organisation”
It has been nearly a decade since the last mega LNG newbuilding program in South Korea was completed. Building forty-five LNG carriers for Qatargas at three major Korean shipyards – Hyundai, Samsung, and Daewoo — had been challenging on many fronts. Several new technologies and systems had to be qualified at the design stage, during plan approval, construction and shop trials and verified during commissioning, gas trials, and sea trials. Anomalies and deficiencies, if left undiscovered, cause rework, costly delays and considerable technical problems after delivery. Fortunately, with a handful of very experienced engineers involved in the QG project from concept to commissioning, it was a job well done in the end, to the Continue reading “LNG shipbuilding boom time ahead. But are we ready for it?”
