At the annual Seatrade Cruise Global 2016 conference in Ft. Lauderdale, Florida, classification society DNV GL introduced a new form of reporting that revolutionizes survey reporting for fleet managers. The newly structured report defines safety barriers and trends, utilizing DNV GL’s extensive experience with barrier management in the offshore oil and gas industry.

In collaboration with a major cruise line, DNV GL successfully implemented the new barrier management reporting programme. Survey data from 23 cruise ships was included in the pilot programme for fleet managers. The test enabled the project partners to identify and present high-impact risk control measures more efficiently than ever before. This allowed the customer to easily measure the effectiveness of risk-control actions.

The capsized Hoegh Osaka

At 2109 on 3 January 2015, the pure car and truck carrier Hoegh Osaka was rounding West Bramble buoy in The Solent when it developed a significant starboard list causing some cargo shift and consequent flooding.

With the list in excess of 40°, the ship lost steerage and propulsion, and subsequently drifted onto Bramble Bank, grounding at 2115.

Hoegh Osaka had sailed from the port of Southampton, bound for Bremerhaven, at 2006. A pilot was embarked and there were 24 crew on board. Following the accident, all crew were successfully evacuated from the ship or recovered from the surrounding waters. There was no pollution. A major salvage operation successfully refloated Hoegh Osaka and it was subsequently taken to a safe berth in Southampton on 22 January.

Dare devil solo round the world yachtsman, Alex Thomson, is once again proving his passion for the extraordinary and showing that a fear of heights can also be overcome too.

After the KeelWalk 2012 and MastWalk 2014, he has now combined his two favourite sports, sailing and kiting, to perform one spectacular stunt. Alex arrived at the beach looking confident in a Hugo Boss suit and tie.

Alvor, near the southern tip of Portugal, is one of the most popular places for kite surfing in the world. With its strong winds and high waves, it is the perfect location for this unique experience. The plan for this new stunt promised pure adrenaline and it certainly more than delivered. Alex was raised up from his yacht with the kite to twice the height of the mast. At this breathtaking height, he severed the connection with the boat and glided back down to the sea, carried only by the kite.

A team of inventors from Sussex, England, has developed a solar and wind-powered boat that can suck up plastic waste.

Bluebird Marine Systems unveiled their proof of concept at the government funded Innovate UK show in London in late 2015 and are now crowd funding the construction of a full-scale vessel.

SeaVax, when built, it will be 44 meters (144 feet) long, have a suction head some 13.5 meters (44 foot) wide, and will be fully autonomous. Deck-mounted solar panels and two wind turbines will feed power to electric pumps and filters that will suck up plastic solids and micro plastics.

Electrical safety: An evaluation of electrical hazards

A series of electrical hazards
A series of electrical hazards

In its latest Safety Bulletin, published in March 2016, the Australian Maritime Safety Authority (AMSA) tackles the issue of electrical hazards full on. Although aimed at those working onboard in an electrical capacity, it serves as a timely reminder of the potential electrical hazards a surveyor may be faced with too.

Electrical hazards can lead to deaths and injuries such as shocks and burns. They can also lead to shipboard fires, explosions and the disabling (through blackouts) of essential equipment and services on board which can compromise safety. Ensuring that the right controls and mitigation measures are in place is critical for maintaining safe operations. To be effective, control measures need to be developed at the organisational, technical and individual levels.

Engine crankshaft deflection measurement

Understanding engine crankshaft deflection measurement will aid a diagnostic engineer

At some time in his career the Diagnostic Engineer may well have to examine the running of a compression ignition engine. Many of the defects that occur on such units are down to wear in the main bearings causing the crankshaft to change its longitudinal straightness. Usually the first diagnostic test on such an engine is to take a series of measurements between the crank webs at various points round the circle of rotation called somewhat in correctly crankshaft deflections. If a driving engine is of the compression ignition type with a cylinder bore above about 250 mm (10 inches), it is also necessary to consider the alignment of its crankshaft. Below that size, the overall stiffness and small size of the unit and the fact that the crankshaft itself is an integral forging make the measurement of crankshaft deflections both extremely difficult and unnecessary.

Updated third generation silicone fouling release coatings

Feature article prepared by the Research & Development Department, Hempel A/S, February 2016 (Original paper published in 2008)

Traditional fouling release coatings consist of a silicone elastomer (PDMS) and rely on a low surface tension (hydrophobic) and a low modulus of elasticity, usually with a good initial foul free performance. With time, the coatings ability to self-clean is lowered, which results in a higher hull skin friction. The invention behind the 3rd generation fouling release coatings is a unique blend of silicone polymers that has and maintains a more hydrophilic surface, with fouling release performance that lasts. The foul free period is longer, and required speed for self-cleaning is lower. This results in a lower hull skin friction over time with potentially lower fuel consumption.

An approach to a modern sailboat lightning protection system

When lightning strikes, and it does, having a lightning protection system can save your life
When lightning strikes, and it does, having a lightning protection system can save your life

We were lucky when we were struck by lightning on our small 35’ GRP cruising sailing boat in Turkey in 2013, but without an LPS. All the plastic and some of the metal gear at the top of the mast exploded (see photo below) and simultaneously the headlining in the saloon exploded downwards with a loud bang. So much smoke that we initially thought we were on fire; but my wife and I survived unscathed to tell the tale. This inspired this article as we need to think about new a approach to a modern sailboat lightning protection system.

The most likely discharge exit was through the propeller shaft, but practically all electronics were violently destroyed and, as an electrical and electronic engineer, my assessment for our insurance claim afterwards showed that most devices had experienced severe arcing with small electronic components having exploded internally (see photo below).

Machinery and its problems for the underwriter

A ships systems – Machinery and its problems for the underwriter

We are haemorrhaging money! This article talks about machinery and its problems for the underwriter. Machinery incidents amount to over 40% of the overall claims paid by underwriters. To give some background, insurers cover the cost of replacing machinery which has broken as a result of negligence by the crew providing such loss or damage has not resulted from want of due diligence by the
insured, owners or managers. This is very wide coverage and effectively acts as warranty insurance for the machinery. Obviously it is open to abuse and insurers trust the owners to be open and honest when presenting a claim for machinery damage.

I have been in the insurance industry for over 30 years and have benefited from the Braemar’s, previously the Salvage Association, monthly reports. The top four causes of casualty are always machinery, grounding, fire and collision in that order. This is also backed up by the International Union of Marine Insurers (IUMI), where the data is kindly provided by Lloyd’s List Intelligence.

In response to a string of major incidents, trade association Interferry has produced operational best practice guidance for fire safety on RO/RO ship vehicle deck.

The guidance is based on input from a questionnaire sent to association members last year following at least seven serious fire incidents on ROpax ferries in Europe since 2010. The two most recent incidents resulted in fatalities and total loss of the ships, prompting the initiative by Interferry’s Operators Policy Committee to identify and publicize a common set of best practice mitigating actions.
