IIMS forms an Inland Waterways Working Group and announces first training event

In response to interest expressed recently by IIMS members, a decision has been taken to form a new inland waterways group. IIMS member, Chris Williams, has agreed to head up the group (supported by several others) under the auspices of Large Yacht & Small Craft Working Group Chairman, John Excell. The initial intention of the group is to meet formally twice a year for training days around the UK and to communicate and network through various social media channels to share information and best inland waterways surveying practice. The first practical training event is planned for Thursday 19 April 2018 at Croxley Green, Watford at the P&S Marine Yard on the Grand Union Canal hosted by Ralph Kitts and Tom Pattle.

The schedule for the day is as follows:
09.00 – 10.30: Practical welding session and inspecting good and bad welds.
10.30 – 10.50: Coffee.
10.50 – 12.30: Surveying a narrowboat, to include ultrasonic testing and where to take readings. Hammer – where to hit the vessel. Pitting. Welds.
12.30 – 13.45: Lunch at the Rising Sun (included in the delegate fee).
13.45 – 14.45: How to translate the survey results into a report.
14.45 – 16.30: Overplating discussion including a presentation from Jeffrey Casciani-Wood with a view to creating some surveyor guidance notes.

The cost of the training day is £120 to include lunch at the nearby Rising Sun, tea, coffee and a copy of the introduction to manual metal arc stick welding. To reserve your place use the reservation form below and we will invoice you. Alternatively, call Cathryn Ward on + 44 23 9238 5223 or email her.

New class notations aim to improve stern tube bearing performance

DNV GL has revised its class rules for single stern tube bearing installations and introduced two new class notations, “Shaft align(1)” and “Shaft align(2)”, to help customers better manage the risk of stern tube bearing failure. The new class notations can be assigned to both newbuilds and vessels in service in conjunction with propeller shaft withdrawal.

The classification rules covering shaft alignment are formulated to achieve an acceptable distribution of loading on the shaft bearings and lubrication of the aft bearing, taking into consideration the bending moment induced by the propeller during operation. However, during turning manoeuvers at higher ship speeds, exaggerated propeller bending moments can occur, potentially resulting in a reduced shaft-bearing contact area and an exponential increase in local pressure and thermal loading. This could cause damage to the aft bearing. Most of the reported bearing damages have been observed in the aft-most part of the aft bearing, typically during a starboard turn on a right-handed propeller installation. The new rules put additional focus on the impact of these transient hydrodynamic propeller forces and moments, induced in turning conditions, on the aft-most propeller shaft bearing.

In the “Shaft align” class notations and the revised main class requirements for single stern tube bearing installations, a multi-sloped bearing design is mandatory. This is further supplemented by an additional evaluation of the aft bearing lubrication condition considering an increased propeller-induced hydrodynamic bending moment on the aft bearing in the downward direction. Additional design and installation criteria also assist to increase the operating margins and enhance bearing performance and fatigue lifetime in normal continuous running conditions.

“We are always looking to push the development of our rules forward to help our customers operate and maintain more reliable and safe ships,” says Geir Dugstad, Director of Ship Classification at DNV GL – Maritime. “With this revision to the DNV GL class rules and the two additional class notations, we will enable owners to enhance bearing performance, and benefit from a longer lifetime in their stern tube installations.”

The notation “Shaft align(1)” is intended for propulsion systems installed on vessels with conventional hull forms and incorporates enhanced aft bearing performance during normal and turning operating conditions. “Shaft align(2)” is intended for propulsion systems requiring additional calculations to predict hydrodynamic propeller loads during turning conditions, for example vessels with non-conventional hull forms such as asymmetric stern, twin skeg etc. Design and in-service follow-up rules for the class notations are included in the updated DNV GL rules for the classification of ships, Pt.6 Ch.2 Sec 10 and Pt.7 Ch.1 Sec 6(38) respectively.

“We hope that by introducing the revised main class rules for single bearing installations and ‘Shaft align (1) or (2)’ we can substantially reduce stern tube bearing failures,” says Oddvar Deinboll, Head of the Machinery section at DNV GL – Maritime. “We’ve received a lot of positive responses from the industry and are already working on some concrete projects.”

Annual Western Mediterranean LYSCWG on 26-27 April

As in previous years, IIMS is hosting an event around the Palma Superyacht Show on the island of Majorca on Thursday 26 to Friday 27 April for large yacht and small craft surveyors. In recent years the event has gone from strength to strength and the agenda for this year looks equally appealing.

On the first morning the group will meet outside the Superyacht Show entrance to be transported the few miles to take a look at the METALNOX facility at Calvia.
Meet at 08.45 – Transfer to METALNOX by bus
Amongst other things to be seen at METALNOX is the Prop Scan computer system which measures the size and shape of the propellers of ships and yachts internationally. Prop Scan is the first certified ISO system for the correction, reconfiguration and optimization of propellers.
13.15 – Lunch back in Palma

After lunch the group will meet in the classroom adjacent to the Superyacht Show for a series of specially prepared presentations.
14.30 – Karen Brain: Understanding your insurance cover. What do Marine Professionals need?
15.30 – Phil Duffy (topic to be confirmed)
16.30 – Bob Hoghton: Mini ISM
17.45 – Close
19.15 – Dinner

A prompt start on the second day within the show itself gives Mike Schwarz, IIMS CEO, the opportunity to bring delegates right up to date with what has been happening in and around the IIMS family over the past few months.

The group will then transfer by bus for the second facility visit, this time a trip to Oscar Sierra before returning to the Superaycht Show. At that point the training event officially concludes and delegates can then enjoy the show for the rest of the afternoon courtesy of a free VIP pass from IIMS.

Oscar Sierra Safety Equipment S.L. is one of the leading marine safety specialists in the Mediterranean. They are both manufacturers and distributors of marine safety equipment. The group will focus on looking at life-saving and firefighting equipment during their visit.

The cost of the event is €190. This includes training and bus transfers on both days, plus a complimentary VIP entry ticket to the show which can be used over the weekend too. Lunch and dinner are at the individual’s cost. Attendance at the event also attracts 5 CPD points.

To register your place at the event please complete the reservation form below or email Cathryn Ward or call her on + 44 23 9238 5223. We will invoice you.

Operators and surveyors urged to test cargo hold’s bilge system to minimise claims

Operators and surveyors urged to test cargo hold bilge systems to minimise claims
Operators and surveyors urged to test cargo hold bilge systems to minimise claims

The UK P&I Club has reminded those working in the marine industry that significant insurance damage claims can result if a bulk cargo is damaged due to the leakage of the bilge system into a loaded bulk cargo hold.

To reduce the chance of such cargo damage, operators and surveyors are advised to inspect and test the cargo hold bilge system as part of the routine pre-loading checks of the cargo holds.

Inspection and testing of cargo hold bilge system non-return valves should be included in routine pre-loading checks of the holds. These non-return valves may not be seated tightly, because of the presence of previous cargo residue and scale around the valve seat.

Hold bilge sounding pipes should be positively proven to be unobstructed and comparisons made between the documented maximum pipe height and actual measurement at the deck datum point. The full depth of the sounding pipes should be confirmed when sounding any cargo hold.

Furthermore, maintenance and operational safeguards must be conducted in the hold bilge system:

Bilge system valves and pipework should be periodically checked and maintained as part of the planned maintenance system.

Rigorous procedures should be in place to prevent valves being left open when not in use.
Should a hold ingress alarm be activated, it should be thoroughly investigated, including checking all related systems and pumping of the bilges to observe for any discharge.

All the above have as a purpose to deal with the the risks of potential damaged cargo and the associated insurance claims.
