The International Organization for Standardization (ISO) has now published the revised ISO 12944 standard.
ISO 12944 is one of the main international standards for corrosion protection of steel by paint. The revision will impact all existing parts of the standard and include a new addition – Part 9 – dedicated solely to offshore structures. Continue reading “ISO 12944 revision”
Recent analysis of the Shipowners Club’s Condition Survey Programme has highlighted that approximately 25% of the vessels surveyed showed evidence of contaminated engine room bilges. As such, Shipowners Club seeks to raise awareness of the potential fire hazards associated with oily engine room bilges and the checks and steps that a ship’s crew and/or surveyor should undertake.
Whilst an oily bilge may not be the immediate source of a fire, any fire that arises in an engine room or machinery space has the potential to escalate and spread rapidly. The presence of oil accumulated in bilges or drip trays act as additional fuel to sustain burning and increase the likelihood of the fire reaching further areas.
Fincantieri’s Palermo shipyard is carrying out the world’s first luxury cruise ship lengthening. Lengthening is not unheard of for merchant vessels, but it has never before been attempted for a vessel of this type as far as is known.
On March 10, workers cut the 36,000 tonne Silver Spirit in half with torches and began the process of pulling her bow and stern in opposite directions. Once they had enough space, they used self-propelled modular transporters to move a new, prefabricated 50-foot section into place. Reconnecting the hull, fitting out wiring and piping and installing interior fittings will take workers about Continue reading “First ever luxury cruise ship lengthening undertaken by Fincantieri”
A new product that removes water from the bottom of diesel tanks is expected to end all diesel bug problems.
The Diesel Dipper is a self-contained system independent of the engine. Fitted with a 12-volt pump, it is designed to suck water from the floor/bottom of a fuel tank below the fuel suction and by doing so, makers Marine 16 say it eliminates or prevents diesel bug and engine failures.
Marine 16 said: “Water and sludge lying on the bottom of the tank is drawn up into a ‘tank separator’ where it separates from the diesel and collects on the bottom. This accumulated water and sludge is then periodically drained off into a container.”
The clean diesel exits the top of the separator and flows through a Continue reading “Possible new cure for diesel bug”
DNV GL has announced a joint partnership to study the safe use of lithium-ion batteries in shipping. The class society’s partners in the effort include flag states, research institutions, battery and propulsion suppliers, fire system manufacturers, shipowners, vessel operators and yards. DNV GL says that the hope is to identify improvements not just for the batteries themselves, but for the associated systems, procedures, and approval processes.
“We put a great deal of effort into ensuring the safety of these new alternative systems, but the cost of the present safety and approval methodology is cumbersome. This collaborative effort gives a chance for an even greater level of safety,” said Rasmus Nielsen, a naval architect and officer at project partner Scandlines.
The project’s deliverable’s are focused on safety. Tasks include the development of Continue reading “Partnership formed to study the safe use of lithium-ion batteries in shipping”
STX France has revealed a concept design for a cruising sailing ship, Silenseas, that aims to reduce energy costs and environmental impact.
STX France has researched sail propulsion since 2009 and developed a patented concept, Solidsail, which makes it possible to reach sail areas of up to 1,200 square meters (12,900 square feet) safely. Arising from that, the company says it can offer the market a range of innovative vessels.
By combining the use of the sails with the latest propulsion and Continue reading “Sielseas concept for sail propelled cruise ships unveiled”
UAE based Enata Marine has launched a stylish superyacht with twin carbon fibre hydrofoils and a hybrid diesel electric propulsion system at the Dubai Boat Show.
The 9.6m long FOILER, also called ‘The Flying Yacht’ due to its ability to operate 1.5m above the water has two BMW 320hp diesel engines which gives it a take-off speed of 17 knots and a maximum speed of 40 knots. The engines are also able to cruise in full electric mode up to 10 knots to reduce fuel consumption by 20% over a traditional yacht.
Enata Marine explains that the diesel engines drive two generators which provide the electrical power. The power is then delivered to two electrical (ENATA) torpedoes that drive the boat.
The retractable red foils fully lift the hull 1.5m out of the water at Continue reading “Stylish and futuristic foiling craft launched by Enata Marine”
Following the collision between Vestas 11th Hour Racing and a non-racing vessel in the final stages of the racing leg in Hong Kong waters, the organisers of the Volvo Ocean Race have commissioned an independent report into ocean racing at night in areas of high vessel traffic density, to establish what steps race organisers may take to mitigate risk going forward.
The collision occurred between the boat Vestas 11th Hour Racing and a fishing vessel, on 20 January 2018, around 30 miles from the Leg 4 finish line in Hong Kong, resulting in the death of one fisherman. He had been recovered from the water and taken on board Vestas 11th Hour Racing and was transferred by helicopter to a hospital in Hong Kong where medical staff were unable to revive him.
Dutch towing group, Muller Maritime, has taken delivery of the harbour escort tug Multratug 32. Despite the high number in its name, it is both the first in its class and the first vessel of its kind.
Designer Robert Allan Ltd. calls it a “Carrousel RAVE Tug,” or CRT, and it integrates two features into a novel new package. First, it has two Voith cycloidial drives arranged fore and aft (the Robert Allan-Voith RAVE design). Second, its towing winch is mounted on a giant circular bearing – the “Carrousel Towing System” – which sits around the entire wheelhouse. With these design elements the tug can rotate with a load on its line, without fouling the towline on its own superstructure or girting. It is designed to pivot relative to its direction of travel, creating drag with the width of its hull.
Robert Allan says that it is the tug’s relative heading that determines the magnitude of the towline force. At speed, large forces can be generated by applying a small amount of thrust to change the tug’s orientation to the escorted vessel. The propulsion system is primarily used to control the tug’s heading, position and speed – not to generate bollard pull. Continue reading “Revolutionary design of harbour escort tug launched”
Requirements for ships to collect data on their fuel oil consumption entered into force on 1 March. Other important amendments to the International Convention for the Prevention of Pollution from Ships (MARPOL) have also entered into force, covering the classification of garbage, including the addition of a new category of “e-waste”, and amendments to the International Oil Pollution Prevention Certificate.
Ship fuel oil consumption data reporting requirements
The ship fuel oil consumption data reporting requirements are the latest mandatory requirements aimed at enhancing the energy efficiency of international shipping.
The data collection will begin on 1 January 2019 with data reported at the end of each calendar year to the International Maritime Organization (IMO), the United Nations agency with responsibility for regulating the safety, security and efficiency of shipping and preventing marine and atmospheric pollution from ships.
“We have been overwhelmed by the positive response from our customers and the industry as a whole,” says Knut Ørbeck-Nilssen, CEO of DNV GL – Maritime. “Many owners have opted not to wait for their first scheduled survey to shift vessels to the new certificates, but have asked to move their whole fleet onto the new system. Our goal for 2018 is to have every vessel in the fleet using electronic certificates in conjunction with their periodic survey.”
Since the launch in mid-October 2017, DNV GL has issued approximately 50,000 certificates, with more than 6,000 vessels of the classed fleet now trading with one or more certificates. Digitally signed electronic certificates represent nearly 80 per cent of all certificates issued by DNV GL since the roll-out. 52 flag states accept the certificates, with further acceptances expected over the coming year.
“The administrative savings for our customers have been significant, in particular in the ease with which customers always have access to Continue reading “From stamp to screen: DNV GL has already issued over 50,000 electronic certificates”
Tritex NDT has launched a new ultrasonic metal thickness gauge specifically designed for mounting onto drones for high level inspections.
The gauge uses multiple echo to completely ignore coatings up to 20mm thick and the single crystal probe ensures accurate readings on curved surfaces, such as storage tanks and pipelines. Remaining metal thickness and corrosion levels can be quickly and more easily checked without the need for scaffolding or rope access.
The Multigauge 6000 Drone Thickness Gauge OEM transmits real time measurements wirelessly up to a distance of 500 metres using its integrated RF transmitter. The readings are displayed and stored on dedicated Communicator software within templates in a grid or string format.
The gauge weighs just 45 grams and the plastic probe weighs only 15 grams. Jon Sharland, Sales Manager at Tritex NDT Ltd, said Continue reading “Tritex NDT launches a thickness gauge for mounting onto drones”
