Understanding hull fouling with Britannia P&I Club

Britannia P&I Club logoBritannia P&I Club has published loss prevention guidance on the consequences that need to be considered regarding hull fouling.

Hull fouling refers to a condition when marine organisms such as barnacles, algae, and mussels attach themselves to a ship’s underwater hull surface area. When operating in tropical or seasonal tropical waters the higher temperatures and sunlight provide ideal conditions for the rapid growth of marine organisms, particularly when the ship is stationary at anchorage for a longer period. Furthermore, during seasonal tropical periods, ocean currents transport nutrients from deeper waters to the surface in coastal areas, promoting the growth of photosynthetic organisms.

Streamlining PSC inspections through AI-powered approach

A ship in port for PSC inspectionPort State Control (PSC) inspections are a fact of life in the maritime world — and they’re getting tougher. With rising detention rates, unpredictable inspection criteria, and mounting pressure on crew performance, preparing for a PSC visit can feel like navigating a minefield, says Kaiko Systems.

In 2024 alone, over 73,000 PSC inspections were conducted globally, with a growing detention rate now over 3%. For vessel operators, a failed inspection can mean costly detentions, delayed cargo, reputational damage, and a hit to operational performance.

Minimum Steel Thickness for Narrowboats: A discussion paper

By Tom Keeling MIMarEST and Peter Brookes CEng, MIET, affillIIMS. Tom Keeling and peter Brookes are inland waterways-based marine surveyors. Both have run independent consultancy businesses in this sector for many years, specialising in the survey of steel thickness of narrowboats and their hulls. 

Man on a bargeMarine surveyors and boat owners are regularly heard to say there is a minimum 4.0mm of hull thickness required at time of survey of a steel narrowboat. Some brokers even publish videos of such information, with some surveyors enforcing it (Whilton Marina, 2012 and 2016). Boaters are subject to it and repair often follows. In a recent article, Geoff Waddington (2021) explains there is confusion in the industry about wastage limits, and consequently acceptable residual hull plate thicknesses, and opinions among surveyors ‘vary wildly’, with some quoting 3mm acceptable minimum plate thickness, others using percentage loss. This short paper explores what a standardised acceptable limit for diminution, and therefore residual steel plate thickness for narrowboats, could be. It describes a variety of methods of calculating the design plate thicknesses (scantlings) and the minimum acceptable residual plate thickness. In doing so, this paper aims to serve as a guide for inland waterways marine surveyors, boat owners, repairers, and insurers alike.

The opportunities and threats presented by report writing software

IIMS and its Professional Assessment Committee remain concerned at the quality of reports that it sees, both in general terms, but in particular when assessing a candidate’s suitability for an upgrade.

The emergence of new surveyors into the industry, coupled with their desire (along with more experienced practitioners) to utilise the latest report writing software is creating a concerning trend. In writing this article we want to remind surveyors no matter what method they use to prepare their surveys of the importance of accuracy and giving sufficient meaningful and detailed, factual information to the client. That is and always will be the role of a marine surveyor. To further illustrate this point, the authors have used some verbatim comments taken from legal teams who have been asked to comment and give opinions on surveyors’ report in courts and for insurance companies when assessing claims and considering potential litigation. For obvious reasons, the sources of these comments are not revealed. Continue reading “The opportunities and threats presented by report writing software”

Commercial sail power is back with a bang – who would have thought it?

It seems we have gone full circle. Cargo ships powered by sail were lost to us a century or more ago, and to the current generation such vessels are regarded as outmoded transportation from a bygone era. But now they are back, more sophisticated and sustainable than ever. Recently I read about the Anemos, which has claimed the title of the world’s largest sailing cargo ship as she made her inaugural voyage from Concarneau, South Brittany, France.

MAIB: Small craft passenger safety must be more prevalent

Small craft passenger safety is pulled sharply into focus by recent events
Small craft passenger safety is pulled sharply into focus by recent events

Poor posture, inadequate seating and a host of other factors can lead to life-changing injuries on RIBs as small craft passenger safety is pulled sharply into focus by recent events in the small craft sector. If the sector’s reputation is to survive accidents like Seadogz, owners and operators need to start owning best practice, controlling the risks and demonstrating that their trips are safe, says MAIB (Marine Accident Investigation Branch). Continue reading “MAIB: Small craft passenger safety must be more prevalent”

First Saudi Red Sea Authority yachting regulations released

Saudi Red Sea Authority yachting regulations have been written and published for the first time by the authorities.

The new Saudi Red Sea Authority yachting regulations outline the necessary requirements and conditions for the use of yachts in Red Sea waters, as well as overseeing the issuance of tourism and leisure licenses and permits, the Saudi Press Agency reported. They outline the conditions and procedures for issuing technical licenses for leisure tourism, and the required criteria for yacht owners or authorized tourism maritime agents.

Certified boats have lower chance of accidents

The American Boat & Yacht Council (ABYC) has released the results of a study that examined the effectiveness of its standards in enhancing boating safety. The research firms Industrial Economics and ITA International conducted the analysis, which used NMMA-certified boats to ensure compliance with ABYC standards through their inspection process. And although the results – voluntary standards (for marine safety) reduce the risk of involvement in a focused accident by 43 to 47 per cent – were reported at a recent seminar, it’s now ‘official’, suggesting that certified boats have a lower chance of accidents.

The advice from Jeanneau is to immediately stop sailing. The company has issued a Continue reading “‘Risk of drowning’ alert for some Jeanneau Yachts issued”

UK Office for Product Safety and Standards issues product recall alert for Honda Marine Outboards

Honda Marine Outboard products present a risk of injuries as it has been identified that the actuator link rod may break
Honda Marine Outboard products present a risk of injuries as it has been identified that the actuator link rod may break

The affected Honda Marine Outboard products present a risk of injuries as it has been identified that the actuator link rod may break during use due to a lack of durability. This can then result in a loss of shift operation, leading to a potential loss of control of the vessel. The product does not meet the requirements of the Recreational Craft Regulations 2017. Due to this, the product has been recalled from end users. Continue reading “UK Office for Product Safety and Standards issues product recall alert for Honda Marine Outboards”

Floating sauna in Oslo fjord rescues occupants of sinking Tesla

This is a remarkable story, one of my favourites for ages, which fortunately had a happy ending. What caught my eye specifically were the details of the good Samaritan vessel – a floating sauna – which came to the aid of a sinking Tesla. I must have led a sheltered life as I was completely unaware that such craft existed and that they are indeed popular in Norway and can be hired by the hour! And being a skipper of a floating sauna sounds like a very cool job – never getting cold on the job either! Continue reading “What caught my eye: March 2024”
