Inventory of Hazardous Materials (IHM) surveys, when carried out correctly, can have a range of unexpected benefits for ship owners. A recent experience not only highlights the value to ship owners of having an approved inventory for their vessels, but also reaffirms the need to ensure that surveys are undertaken correctly.
Hazardous materials consultancy Lucion Marine was appointed to assist a major cruise line with work on a 2008-built cruise vessel. In this particular case a shipyard, on a pre-refit visit, claimed that an area where a new scrubber installation was planned contained asbestos in the bulkhead fire insulation.

‘…The ship wherein Theseus {ref.2} and the youth of Athens returned had 30 oars, and was preserved by the Athenians down even to the time of Demetrius Phalereus for they took away the old planks as they decayed, putting in new and stronger timber in their place…’
per Plutarch in Life of Theseus {ref.3}
Like their predecessors of ancient times, the marine surveyors of today inspect and make recommendations in respect of the state of seaworthiness (or lack thereof) of a vessel. Unlike their predecessors, and unsurprisingly, their role has expanded. Continue reading “The role of the marine surveyor – a P&I club’s perspective”
The Maritime and Coastguard Agency (MCA) carried out a second public consultation, which ran from 29 May 2019 to 10 July 2019, on proposals resulting from a review of the standards relating to older domestic passenger vessels, which are currently less stringent in some areas than those which are applied to newbuild vessels. Some proposals had been revised in the light of comments received during the first consultation, which ran from 6 November 2018 to 29 January 2019.
In some cases, there is a safety gap between the standards for new ships and those for older vessels. The review seeks to bring the standards applied to existing vessels into line, wherever possible, with those which apply to new vessels in key safetyareas.
Transport Canada Marine Safety and Security (TCMSS) has published a policy on the acceptance of the American Boat and Yacht Council (ABYC) standards as an approved alternative method for small vessel compliance in Canada. The policy is effective as of October 30, 2019.
“Having one set of standards throughout North America is a huge benefit for engineering, manufacturing, and trade for the marine industry,” said Craig Scholten, ABYC Technical VP. “Being able to design, certify, and produce product to one standard will streamline and simplify everyone’s efforts.”
TCMSS will accept the equivalent standards published by ABYC with some Canadian modifications. The policy affects pleasure craft less than 24 meters and other craft of not more than 15 gross tonnage constructed, manufactured or rebuilt in, or imported into Canada.

A naval architect has warned that as European offshore wind markets continue to expand with larger and more ambitious projects, there is a looming shortage of Crew Transfer Vessels (CTV).
Chartwell Marine said that expedient investment in new builds will be required to tackle a shortage of 22m – 24m offshore wind crew transfer vessels, especially as build slots at yards are limited. Many of these existing vessels, commonly used for UK CTV operations, have reached retirement or require a refit following over 10 Continue reading “CTV shortage as offshore wind growth accelerates warns naval architect”
Salvage companies faces numerous challenges. Image courtesy of Tsavliris Salvage Group
The salvage industry faces numerous challenges nowadays. Salvage cases tend to be more complicated technically and expensive. This is, in large measure, due to the increased size of vessels, increased values of their cargo and external influences such as demanding requirements from governmental organisations and the shore-based authorities. There are fewer cases for salvage companies and yet society’s expectations about protection of the environment have increased.
Speakers at the Gard Conference on container fires
Container ship fires are a growing concern. Fires, originating from dangerous goods in containers, whether wrongfully declared or not, occur with alarming frequency. During the Gard conference it was revealed that Gard’s cargo claims team determined that on average there has been a fire onboard a container ship weekly during the first half of 2019 and this does not include “near misses”. Obviously, such fires endanger the lives of the crew – a burning ship mid-ocean is a very dangerous place and being tasked to tackle such a fire exponentially adds to the risk.
The IVR Association has published an information document explaining the hidden risks of biological corrosion and providing additional information on how to avoid bacteria that damages ship bilges. The technical leaflet Biological Corrosion focuses on a number of cases where the issue of leaking engine rooms seems to be more and more common as a result of this type of corrosion.
In recent years, an increasing number of cases of leaking engine rooms, caused by very local perforations of the ship’s plating have been noted. This happened despite the recent class renewal in which bottom inspection and thickness measurements showed that the plating was sound. In these cases, investigation reveals that the water ingress is by very local corrosion perforations. Continue reading “The hidden risks of destructive biological corrosion”
David Patterson, North P&I Club, the author of a case study on safe working with CO2 systems
North P&I Club has published a study following a recent incident that resulted with the loss of ten people onboard a vessel, highlighting the dangers when the operation of fixed CO2 systems is not fully understood.
The incident occurred whilst the vessel was in dry dock. A junior officer was tasked with getting details of the fixed systems CO2 bottles in the vessel’s CO2 room. While the junior officer was in the CO2 room, he discovered a leak from one of the cylinders. In an attempt to stem the leak, a pressure increasing valve was mistakenly opened, which increased the pressure in the system and resulted in the release of all the cylinders in that bank.
Liftboat, Ram XVIII, overturned in the Gulf of Mexico
The US National Transportation Safety Board published its report on the liftboat Ram XVIII, that overturned in the Gulf of Mexico, on November 18. Due to the incident, three personnel suffered minor injuries, while about 1,000 gallons of hydraulic oil were released. The vessel was declared a constructive total loss at an estimated $1,140,000.
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.
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.
